Economic Aspects and Cost Effectiveness Criteria in Systems Engineering

Massimo Pica

Editor’s Note: the SyEN version of this article is abridged. Click here to download in .pdf format the full version of Mr. Pica’s article, with full calculations.

The devil is in the cost details. At least, this is the case for systems’ users around the world who face the herculean task of procuring, deploying, and maintaining reliable systems, equipment and materiel. If, generically speaking, we refer to a “system” as every type – however complex – of designed asset, system procurement processes are influenced not only by the initial purchasing cost of a system, but particularly by all costs arising before, during and after the system is delivered for operational use. This would also include its respective retirement stage at the end of the system life cycle. The total amount of these costs, for a single system, is commonly defined as “Life Cycle Cost” (LCC).

Designing a system, component, or process to meet desired needs is a decision-making process (often iterative) in which the basic sciences, mathematics, and the engineering sciences are applied to convert resources optimally to meet these stated needs.

Typical users’ expectations are for systems that comply with operational needs and are reliable and competitive from the point of view of costs throughout the system life cycle (system Life Cycle Cost (LCC)). This is the dominating value in the selection of affordable systems to be procured and deployed: in fact, this sort of decision is influenced not only by the initial unit acquisition cost but, more significantly, by all subsequent unit costs, including retirement.

In order to evaluate the Life Cycle Cost of a given system, a basic knowledge of the schedule evolution of the life cycle, and of the procedures involved in its management, is required. ISO/IEC 15288, “Systems and software engineering – System life cycle processes”, describes stages and processes occurring during the life cycle of systems. One of the basic decisions to be made is to choose between the design of a new system (the make option) and the purchase of a system already deployed and available on the market (the buy option). In the first of the two instances, Life Cycle Cost studies are required, so that the LCC can be quantitatively determined, e.g. for the purpose of comparing alternative solutions or different economic options, thereby aiming at the best choice.

In many cases, LCC studies have to be reiterated along the life cycle, e.g. to support modifications of user requirements or configuration change proposals.

According to ISO/IEC 15288, the life cycle of a generic system is composed of the following stages:

C0NCEPT DEVELOPMENT PRODUCTION IN SERVICE RETIREMENT

Figure 1

“The Concept Stage starts after the decision to fill a capability gap with a materiel solution and ends with the requirements specification for this materiel solution. The purpose is to evaluate the needs, potential risks, and cost benefit of a proposed system or a major upgrade of an existing system prior to any commitment of resources. One or more alternative solutions to meet the identified need or concept are developed through analysis, feasibility evaluations, estimations (such as cost, schedule, market intelligence, and logistics), trade-off studies, and experimental or prototype development and demonstration.”

The system LCC estimation serves the purposes of (1) ensuring that all costs to be incurred (typically arranged in a Cost Breakdown Structure (CBS) and explained in the CBS dictionary) are correctly accounted for, and (2) obtaining the system LCC as the minimum reasonably possible. The LCC estimate must include all cost elements, with their estimated costs, which are derived from a technical assessment of the system, as well as from schedule elements of interest; all of these are translated into economic values, using appropriate cost analysis techniques. Technical issues are iteratively re-examined in specific design reviews before reaching confidence concerning compliance of basic design requirements, capability requirements, and fitness to operational scenarios, with respect to the assumptions taken into account in the cost estimates. This is when the budget for the system acquisition program can be prepared.

Traditionally, attention has been given primarily to the optimization of system acquisition costs, whereas operating costs (occurring in the Utilization Stage) and maintenance costs (incurred in Support Stage) are not given thorough consideration. Actually, technological innovations characterising advanced systems require a careful balance of the whole acquisition, ownership, and retirement costs, which comprise the Life Cycle Cost, in order to avoid unjustified trends in cost growth.

In budgeting for the LCC, it is appropriate to build up a cost profile, representing graphically the unit cost behaviour along the system life cycle; all costs are expressed as present values, referred to a single initial point in time. In this way, an ‘equivalence base’ is created, so that LCC values can be estimated and compared for the different alternatives envisaged.

Figure 2

Of course, annual costs are subject to the variable influence of inflation rates; this, in turn, influences the annual expenditure planning, based on the actual value year by year.

Correlation of the following enables the financial analysis to be carried out correctly: i (interest rate or actualisation rate inclusive of inflation), i’ (rate neglecting the inflation), and e f (annual inflation rate).

Editor’s note: Use the link provided at the beginning of this article for the formulas for the calculations.

We can proceed further to arrive at a typical expression for the Life Cycle Cost. LCC is to be considered, as it actually is, comprised of a certain number of cost elements (Cmn) characterised by a double subscript: m (indicating the cost element category, variable between 1 and M) and n (indicating the year corresponding to the generic cost element, variable between 1 and N). Since the cost values Cmn are future values, they can be actualised using the previous relationships.

The LCC estimation process offers a number of basic elements to support decisions not only during the early life cycle stages, but in all subsequent periods. Specific decisions are required to manage maintenance policies and to carry out trade-offs between different possible alternatives, until the system life comes to its projected (and perhaps, to some extent, unpredicted) end.

The following relationship:

FOM =

introduces the helpful quantitative tool called ‘Figures of Merit’ (FOM), by which any system to be procured can be characterised on the basis of calculated values of System Effectiveness and Life Cycle Cost.

From a quantitative point of view, the effectiveness of a generic system is defined as a function of system performance and mission profile. It has to be considered as a goal to be taken into account since the very early stages of the life cycle, in which a larger degree of freedom is allowed in the implementation of system requirements:

SE = A0 * D0 * C

Where:

SE (System Effectiveness) is a measure of the ability of a system to achieve a set of specific mission requirements.

A0 (Operational Availability) is a measure of the degree to which a system is in the operable and committable state at the start of the mission, when the mission is called for at an unknown (random) time.

D0 (Operational Dependability) is a measure of the degree to which an item is operable and capable of performing its required function at any (random) time during a specified mission profile, given system availability at the start of the mission.

C (Capability) is a measure of the ability of an item to achieve mission objectives, given the conditions during the mission.

The three components of System Effectiveness, Availability, Dependability, and Capability, are therefore measures of a system’s ability to operate (in probabilistic terms of duration, repetition, and efficacy) during a specified operational mission.

Editor’s Note: See [URL] for a more detailed version of this paper that includes a case study of System Effectiveness.

System Operational Availability (AO), which is one of the components of this FOM, is, in turn, a function of the mean time between system maintenance operations and of the maintenance downtime:

One of the main design parameters influencing the System Operational Availability is the System Reliability. According to the very basic principles of the Reliability theory, the greater the mean time between system failures (i.e. MTBF), the greater it’s Reliability.

Life Cycle Cost

Figures of Merit are also dependent on Life Cycle Cost, so that LCC values, calculated for a range of solutions to be evaluated for their feasibility, will be correlated with the corresponding values of System Effectiveness.

For a given system, Life Cycle Cost can be plotted, for convenience, against system Reliability (or MTBF). This relationship is illustrated in the figure below.

Figure 3

This graphical representation shows that any increase of MTBF (mean time between consecutive failures) requires higher initial investment costs and higher production costs, due to the insertion of more reliable components. This is counterbalanced by lower costs for logistics (equipment and personnel) and maintenance, both corrective and programmed.

Whenever a system becomes unavailable, its LCC can be significantly influenced. Actually, failures or malfunctions require using alternative equipment or terminating a mission, both of which cause an increase in LCC. There is also an analytical correlation between the failure frequency at component level and the mean time to repair the system and restore its functionality (usually abbreviated as MTTR), which, in turn, influences the system downtime.

The unit costs (i.e. costs for each system to be procured), pertaining to the following (indicative) high level cost elements, are taken into account:

CONCEPT, DEVELOPMENT

Management

Design

Test

Technical documentation

PRODUCTION

Investments for production facilities

Manufacture

UTILIZATION & SUPPORT

o Operation

Support

personnel

spares and repair parts

test equipment

packaging etc.

maintainers’ training

support facilities and services

data management

RETIREMENT

System shutdown

System disassembly and removal

Recycling or Disposal

Figure 4

The ‘prime factors’ of a Figure of Merit are graphically represented in the figure above. FOM is a Cost-Effectiveness parameter synthesising the overall life-long system performance and its corresponding cost, referred to the whole system life cycle; System Effectiveness may be regarded as a collective term used to describe the system availability performance, and its design factors, e.g. reliability, maintainability, and logistic support. Acquisition, ownership, and retirement costs should be estimated as early as possible, so that responsible authorities can find an optimum balance between System Effectiveness factors and Life Cycle Cost.

Figure 5

B.S. Blanchard, Professor Emeritus at Virginia Tech, in his bestselling book “Design and Manage to Life Cycle Cost”, albeit written more than 30 years ago, and in a number of further publications captured the iceberg picture to represent the contrast between the acquisition costs (relatively well known, hence placed above the water line) and the ownership and retirement costs (largely unknown, therefore represented below the water level). Two main aspects conceptually significant for the life cycle of any (defense) system are emphasised by Prof. Blanchard, namely:

o different “visibility” of Life Cycle Cost components (in accordance with the iceberg metaphor);

o the fact that it is at the early stages in an acquisition program that the greatest gains can be realised in terms of the system Life Cycle Cost (however taking cautiously into account some downstream events that can occur during the life of the system, influencing the Life Cycle Cost itself, e.g.: life cycle schedule slips, changes in quantity of systems to be deployed and/or in their operational conditions; and significant improvement programs).

Figure 6

Concerning the cost vs. performance relationship, Augustine’s law states that: “The last 10 per cent of performance generates one third of the cost and two thirds of the problems”.

Figure 7

If we need to compare two different solutions (say A and B) to implement a system requirement, the results of a break-even analysis can be useful to illustrate the annual costs of the two configurations and identify the point in time when the costs are equal across the life cycle. This is depicted in the figure below. From the figure, it appears that, if the system is somewhat complex and its life cycle time overcomes a certain duration (10 – 15 years), then Solution A may become preferable.

Figure 8

On the other hand, it is possible that specific constraints from the type of system, its mission profile, the embedded technologies, the life cycle duration and the risks of obsolescence dictate the adoption of Solution B, for example, if the life cycle time is shorter.

Editor’s Note: See the previously referenced link that includes an example of selection between two alternatives on the basis of LCC, and also provides a sensitivity analysis.

Evaluation of System Economic Life

In several Systems Engineering problems, the evaluation of system economic life is a major economic issue, from the point of view of its applications in optimising the LCC (in compliance with system life cycle planning) and in looking for alternative solutions to arrive at the most suitable configuration(s) on the basis of LCC. The previously referenced longer version of this article includes a discussion of how to evaluate (in theory) a system economic life, taking into account the following necessary information: acquisition cost; annual percent value decrease; annual utilisation and support costs; cost compounding rate.

The Economic Life and the System Replacement Problem

The estimated value of the optimum economic life of a generic system makes it possible, for instance, to determine in which point in time it is best to replace the existing system, in accordance with exclusively economic criteria, with a new system suitable for the same operational profile. In order to achieve this goal, the procedure can be different from the aforementioned method based on annual values. The feasible alternative is based on present economic values.

We can calculate both the optimum replacement period for the system and the life cycle duration for the alternative system by evaluating the Net Present Value (NPV) of each feasible combination of the two life cycles, then choosing the minimum cost NPV (or else, the maximum NPV of net incomes), having noted that this procedure is in principle applicable only if time intervals are the same for the two systems. As a consequence, the first basic problem derives from the different combinations between the durations of the life cycles of the existing system and the alternative system: for example, one year plus four years, versus three years plus five years. Therefore, we can conclude that we have to compare the NPV on a total, respectively, of five and eight years, hence altogether 40 combinations. This complication can be overcome by assuming an infinite series of replacements or, for instance, an existing system for one year of life and infinite replacements with alternative systems, each one for four years of life. This assumption can be compared to assuming a system with three years of life and infinite replacements with alternative systems having five years of life each. The utilization of infinite series is an important method to determine the optimum system life duration: in this case, each combination has an overall life cycle of infinite duration and, therefore, the comparative criteria based on NPV are correctly applicable and, furthermore, the analytical process is much simpler.

Editor’s Note: The longer version of this article provides a numerical example appropriate to solve the following problems:

(1) Beginning from now, how long is it convenient to wait before replacing the existing system with an alternative system?

(2) If there is no replacement, what is the optimal remaining life of the current system?

(3) What is the optimal life cycle duration of the alternative system?

Conclusions

Systems of interest to engineers are becoming more and more complex; therefore, it is necessary that engineers have the capability to analyze, synthesise, and design complex systems. Designing a system is a multi-variate challenge, involving complex decisions in selecting among different solutions complying with the same specifications. These decisions are in most cases dictated by economic considerations.

Concerning the most complex cases of Systems of Systems (SoS), as defined by the International Council on Systems Engineering (INCOSE), it should be emphasized that SoS are significantly different from stand-alone systems from the design perspective. For example, in a SoS, composed of interdependent systems connected to one another in order to provide a given performance, losing part of the system will cause a remarkable degradation of the performance of the whole SoS.

From an economic perspective, the choice of applicable cost models is related to a number of discrimination criteria, the major ones being: the SoS stakeholders, the SoS architecture and its lead system integrator, and additionally the degree of independence of SoS components in term of the activities required to them in each life cycle stage. In this respect, for the purpose of useful applications of cost models to SoS, it is essential to refer to strategic objectives of the organization concerned, especially contracting agencies and user communities. Secondly, having defined the identity of lead system integrators, they will be not only responsible for selecting the SoS architecture(s) but also, as a consequence, for the integration and test activities representing significant cost elements to be properly evaluated. Finally, the degree of independence of Life Cycle Management activities for individual components will certainly have an impact on the selection of cost models applicable to CBS elements of the SoS, avoiding overlaps and double counts of the costs.

Realizing a SoS means a trade-off between different systems, both from the point of view of performances and, especially, costs. From the general Systems Engineering perspective, SoS implications with respect to ‘elementary’ systems can be (indicatively) referred to: broader technical content, higher complexity of integration activities, dynamic and challenging design scope, with significant elements of uncertainty, advanced design optimisation needs, continuous architecture review, sophisticated SoS simulation models, careful interface design and management.

Concerning the prevailing economic issues, cost estimates for a SoS represent complex activities, with respect to simpler systems, noting the extreme variety of possible choices for the overall SoS configuration built on its individual systems. Cost analysts should therefore consider the adoption of more appropriate and advanced estimation methodologies, either analytical methods or, as appropriate, Decision Support methods.

The Importance of Emotions in Software Engineering

A recent study by the Carlos III University of Madrid (UC3M) investigates the importance of emotions in software engineering. In the study, requirements engineering is considered. There is a good reason for this specific focus. The scientists have applied a tool of social psychology, the affect grid invented by J. A. Russel. As the authors of the studies explain, this instrument provides emotional outlines for different versions of the requirements, in addition to facilitating an analysis of the emotions of those involved in the development of the system. The results of the study show that emotions need special consideration when negotiating and establishing requirements.

Fuzzy Hierarchical Decision Modeling

Michael Khader

Lambert Publishing Company

Fuzzy Hierarchical Decision Modeling by NJIT Associate Professor Michael Khader has been re-issued by Lambert Publishing Company in a soft-bound text. The book, originally published in 2009 by Walden University, focuses on applying decision modeling rooted in fuzzy theory and hierarchical analysis to complex problems in networks’ design and acquisition. The book features the analytical hierarchy process (AHP) and fuzzy sets which can be used to deconstruct a complex decision with incomplete information into a set of factors and solutions. The factors and solutions are based on business-related goals and objectives to fit business growth and continuity in changing markets. This is especially believed to be true in the telecommunication market, where established players are leaving and new ones entering. Using the described model allows key decision-makers to arrive at conclusions with a high degree of confidence although the information used in the decision-making process remains uncertain. The model is designed for a single decision and group decision-makers. The model is important because, unlike other models based on well-defined factors and well-defined solution alternatives, this model is based on incomplete and uncertain information. The model’s use is not limited to the networking and telecommunications fields, but also can be applied to areas of business and social significance such as choices of alternative energy, real-time fuzzy control, as well as budget and resource allocations.

The 77 Deadly Sins of Project Management offers a compilation of contributions by experienced project managers who discuss common ‘sins’ that hinder, stall, or throw projects off track. From personal experiences and historical events to the costs of failing to understand these project management challenges, this book is a ‘must’ for any technical library strong in project management guides.

Special Issue of Enterprise Modelling and Information Systems Architectures (EMISA)

An International Journal

This Special Issue is dedicated to capturing the current state-of-the art in the area of modelling tool research with a focus on methodical development of modelling tools. We strongly encourage submissions that go beyond ‘yet another modelling tool’ and invite submissions that address research challenges and direct further research. It is expected that the submissions are based on sound methodical, theoretical, conceptual-analytical and, where appropriate, hermeneutic and/or behaviouristic approaches (e. g. case study-based research). Submissions may not have been submitted or be under consideration elsewhere and must constitute original work. It is possible to submit a major revision of a manuscript already published in workshop or conference proceedings given that the earlier publication is properly referenced. In addition, it must be clearly described and/or marked which parts of the manuscript have been revised and of what nature the changes are.

Standards and Guides

ArchiMate 2.0 Technical Standard Approved

ArchiMate is The Open Group’s open and independent modeling language for enterprise architecture, supported by different tool vendors and consulting firms. ArchiMate supports enterprise architects in describing, analyzing, and visualizing the relationships among business domains in an unambiguous way. ArchiMate offers a common language for describing the construction and operation of business processes, organizational structures, information flows, IT systems, and technical infrastructure. This insight helps stakeholders to design, assess, and communicate the consequences of decisions and changes within and between these business domains.

ArchiMate(R) Version 2.0 Technical Standard was approved by the Board of the Open Group, during its Jan-Feb 2012 conference in San Francisco. The ArchiMate 2.0 technical standard represents the ArchiMate language definition as it exists today. The language definition of version 1.0 resulted from the ArchiMate project, and was initially maintained by the ArchiMate Foundation. The ArchiMate 2.0 standard provides a tighter alignment with TOGAF, while still ensuring backward compatibility to the pre-existing ArchiMate 1.0 standard.

The ArchiMate standard is hosted by The Open Group’s ArchiMate Forum, which is actively working on the dissemination and further development of ArchiMate. The standard can be downloaded from The Open Group’s ArchiMate Forum website.

A Definition to Close on

System(s) of Systems, System(s) of Systems Engineering (SoSE)

system of systems: Modern systems that comprise system of systems problems are not monolithic; rather they have five common characteristics: operational independence of the individual systems, managerial independence of the systems, geographical distribution, emergent behavior and evolutionary development:

Source: Sage, A.P., and C.D. Cuppan. “On the Systems Engineering and Management of Systems of Systems and Federations of Systems,” Information, Knowledge, Systems Management, Vol. 2, No. 4, 2001, pp. 325-345.

system of systems: System of systems problems are a collection of trans-domain networks of heterogeneous systems that are likely to exhibit operational and managerial independence, geographical distribution, and emergent and evolutionary behaviors that would not be apparent if the systems and their interactions are modeled separately.

Source: DeLaurentis, D. “Understanding Transportation as a System of Systems Design Problem,” 43rd AIAA Aerospace Sciences Meeting, Reno, Nevada, January 10-13, 2005. AIAA-2005-0123.

Robert’s Comments: I like the above definitions of system of systems a lot, because they make a useful distinction between systems in general, and systems, the engineering of which gives rise to particular challenges and emphases, because of the distinguishing features stated in the definitions. Of course, in a purely literal sense, almost any system is a system of systems (things constructed of two or more interacting parts).

System-of-Systems Engineering (SoSE): System-of-Systems Engineering (SoSE) is a set of developing processes, tools, and methods for designing, re-designing and deploying solutions to System-of-Systems challenges.

Source: http://en.wikipedia.org/wiki/System_of_systems_engineering

Robert’s Comments: The above definition of System-of-Systems Engineering (SoSE) sits perfectly with the two definitions of system of systems.

System-of-Systems Engineering (SoSE): System of Systems (SoS) Engineering is an emerging interdisciplinary approach focusing on the effort required to transform capabilities into SoS solutions and shape the requirements for systems. SoS Engineering ensures that:

individually developed, managed, and operated systems function as autonomous constituents of one or more SoS and provide appropriate functional capabilities to each of those SoS

political, financial, legal, technical, social, operational, and organizational factors, including the stakeholders’ perspectives and relationships, are considered in SoS development, management, and operations

a SoS can accommodate changes to its conceptual, functional, physical, and temporal boundaries without negative impacts on its management and operations

a SoS collective behavior, and its dynamic interactions with its environment to adapt and respond, enables the SoS to meet or exceed the required capability.

Source: Systems of Systems Engineering Center of Excellence

Robert’s Comments: The first bullet point above seems to capture the essence of System-of-Systems Engineering (SoSE). Regarding the second bullet point, one would hope and expect that applicable political, financial, legal, technical, social, operational, and organizational factors, if any, including the stakeholders’ perspectives and relationships, are considered in system development without exception, regardless of the system. To do otherwise is bad systems engineering. The third bullet point seems obtuse. The last bullet point would seem to apply to every engineered system, no exceptions.

System-of-Systems Engineering (SoSE): System of Systems (SoS) Engineering deals with planning, analyzing, organizing, and integrating the capabilities of a mix of existing and new systems into a SoS capability greater than the sum of the capabilities of the constituent parts.

SoSs should be treated and managed as a system in their own right, and should therefore be subject to the same systems engineering processes and best practices as applied to individual systems.

Differs from the engineering of a single system. The considerations should include the following factors or attributes:

Larger scope and greater complexity of integration efforts;

Collaborative and dynamic engineering;

Engineering under the condition of uncertainty;

Emphasis on design optimization;

Continuing architectural reconfiguration;

Simultaneous modeling and simulation of emergent System of Systems behavior; and

Rigorous interface design and management.

Source: Defense Acquisition Guidebook (DAG) – 2006 Definition of SoSE

Robert’s Comments: The above definition of System of Systems (SoS) Engineering would seem to apply to the engineering of all systems. Of the list of so-called differences, the first is arguable; continuing architectural reconfiguration may or may not apply to any system depending on circumstances, and the rest of the alleged differences would seem to be factors in engineering of any system.

I am not convinced that a differentiation of “system of systems engineering” and “systems engineering” is helpful, at least with respect to choice of words. However, recognition of the specific additional challenges of engineering systems from subsystems that are subject to operational and managerial independence, may be geographically distributed, and may well exhibit evolutionary behaviors not under the control of the developers of the parent (SoS) system – that is extremely valuable. Research in this area from participants such as Purdue University’s College of Engineering (USA), National Centers for System of Systems Engineering (Old Dominion University – USA), and others will contribute to mankind’s ability to successfully engineer complex socio-technical systems.
