Modelling as a Tool in the Engineering of Systems of Systems

By Jan Roodt



Golden Gate Bridge[1]

Modern engineering is continuing to push the boundaries, just like the civil engineering of the previous centuries did within the context of those days. Building the large span bridges like the Golden Gate Bridge shown above, was not a simple feat. Engineers had to consider new materials, new ways of construction, the geography of the region (on a known planetary fault line and prone to earthquakes), and many other issues. What is interesting is that engineers have been using models since antiquity to first of all sell their concepts, and then to ensure that the final product adhered to the original intent as closely as possible.

In this short article I want to consider the challenges faced by modern system engineers dealing with complexity. A short introduction to the concept of complexity (and why it is relevant to system engineering) will be followed by some ideas around the modelling of systems that exhibit the properties of complex systems.

Complexity surrounds us

There are many definitions and descriptions for the concept of complexity. I like to consider complex systems, mainly because complexity can be thought of as a systemic property [1]. Furthermore, my interest in this article is in those systems with a multitude of interacting, hierarchical elements, some of which may be human, or elements with non-linear behaviour, like fuzzy control systems. The problem with these types of systems is that is almost impossible to determine how all the elements may interact at any given time, or what sort of system level behaviour may emerge. Given a certain behaviour, it follows that it is also difficult to understand how each of the components contribute to the observed, emergent operation.

Complex systems are sensitive to small perturbations: this immediately raises concerns around repeatability, and what worked last time may turn out not to be a solution this time. If the system adapts over time, as all complex systems do, it implies that a strategy that worked today may not work tomorrow. Casti [2] gives us a few pointers to try and identify complex systems. Complex systems:

  1. Have a moderate number of “agents” or elements,
  2. Are intelligent (capable of non-linear response) and adaptive,
  3. Rely on “Small World” interaction.

Agents are entities with input-output behaviour, acting on information and adaptive, taking history into consideration, so they can compare past with present. It has access to a basic learning algorithm. The number of agents is more than a few, but less than a multitude. This means that there is enough interaction to ensure richness, but not so much that we can approximate the behaviour by statistics. Small world interactions dictate that a network is established between “nearest” neighbours and no single agent has access to all the signals in the environment, but relies on the network for access to information. To design and instantiate any system to work in such an environment or to be a part of such a system, one must understand if it itself will be a complex system and how to bound the design space.

By definition a system has a boundary and complex systems have “ports” or porous boundaries through which they interact with the environment (which one could see as a system too). The complex system derives information from the environment, acts on it and reacts on feedback. This supplies the complex system with context and obviously makes demarcation of the appropriate boundary to the space to be considered during design. Philosophically speaking, if one considers the Universe a system, the big question is where the boundaries are, and how the system is “open”. If it is not open, one can claim that it is not complex! In any socio-technical system (a collection of human or “aware” agents and machine elements that interact in an integrated way), the system behaviour arises from multiple interactions amongst the constituent parts, and in as a result of its contextual connectedness to the environment in which it is embedded [3].

As I am interested in developing some ideas around the engineering of systems-of-systems, my argument is that “boundary” establishment and management must be seen as a crucial part of the initial work. Without understanding how the system interacts with its environment, and where the environment “begins and ends”, the task of defining the system context in any sense – ontologically or phenomenologically, is almost impossible.

In short then, most of our modern systems are of a socio-technical nature and are complex. New service-oriented systems must be devised daily, for example and it is expected that the system engineer will ensure that the delivered solutions match the (rapidly changing) market requirements, that it can be adapted over time and sustained and serviced as needed over its full life cycle, and that it is (and remains) interoperable with other systems [4] amongst other things. How do we go about successfully defining and developing new systems in such an environment?

Modelling to Understand

In a recent book on the topic of the design of complex systems, Aslaksen [5] makes an urgent case for top-down design approaches to ensure that systems achieve their required operational goals. I have adapted his diagram slightly to highlight the process.


We are all aware of the fact that almost all the large projects we encounter these days require new technology innovations. What Aslaksen is saying is that if we start from our established base and we design solutions with that context only, we will get more of the same and possibly a large mismatch with the required capability of the system. His counter proposal is to start with the conceptual functional solution. I am saying that a process in a tight cycle with bottom-up methods should be followed and the way to achieve this is to use modelling extensively to synthesise existing and conceptual technologies and processes into a continuous evolutionary solution space. This does not mean that we have a shifting baseline in the worst sense, but rather that the technology trends can be utilized more effectively to track the changing requirements space as part of a through-life approach to the solution.

According to Cilliers [6], modelling allows us to build an understanding of things. At the same time he is careful to state that complex systems may be problematic in this sense and one of the reasons mentioned [7] is the notion of incompressibility. The idea is that there is no accurate model of the system that is simpler than the system itself: we need to use the system as the model! This is perfectly reasonable from a philosophical perspective, but has limited value in engineering. As a physicist I believe that Cilliers is correct and as an engineer I hold that we must find ways to work around his constraint. Indeed, Cilliers specifically does not argue against modelling, but only argues that no perfect model can be found for a complex system.

Going back to an earlier statement that the system boundary management is a key element of system engineering, it may be possible to use modelling techniques and tools that start from context setting to derive reasonable and appropriate system solutions. The context will dictate the level of detail needed in the functional and ontological sense. Building software models in a cyclic manner, that is, modelling more detail in a functional sense only up to the point that the system elements seem to deliver a coherent solution to the need, may hold the key. The following diagram shows what modelling methods are appropriate to describe what type of phenomena.

Model Framework.jpg

Some models in physics approach the laws of nature, like the conservation of energy. It is possible to write down equations for these relationships that accurately describe the phenomenon to the best of our current knowledge. I refer to these on the Y-axis as puzzles. At the other end of the scale are the messy realities where we know that it is difficult to derive an optimal solution. We have no way of knowing that we have indeed discovered an optimal solution, or if one in fact exists. Here the only way to describe the problem would be to have a model that frames the context and relationships, a qualitative model rather than a quantitative one.

The interesting thing is that once such a descriptive and coherent model exists, it becomes possible to derive functional and causal models at the level of system behaviour, which in turn allows us to understand how the system elements may be interacting. This does not mean that we have a full understanding of the non-linearities in the system. It only means that we can isolate contextual blocks that can yield to known design approaches, like SysML [8]. Constantly jumping into the detail and then standing back to evaluate the result allows us to develop a system level model and understanding that may be used to design the first functional description of the complex system we need to develop.

The Case of Command and Control Modelling

Command and Control (C&C) in military systems is not a simple thing to model as it relies heavily on the people making decisions and advanced supporting technologies, like networks, radios, etc. It is a classic social-technical system.

A current project allows us to experiment with the methods described above in this domain of military affairs. The goal is to develop an adaptive doctrine and resulting C&C for use in modern warfare. It was found that setting a context and describing the boundary of the system to be developed highlighted several issues. It was discovered that the C&C remains complex, no matter what functional level or hierarchical level of military organization was designated. C&C remains complex in the sense described by Casti and listed earlier, whether it is studied at the level of an air defence battery, or at the level of a battalion. The people and their actions and decision processes are core elements that drive the system behaviour.

However, it is recognized that in terms of relationships and patterns, one can make a case for a process description that could scale, given that the human agents are modelled to interact in a non-linear way with the process, in response to a well defined set of environmental stimuli. Mixing event based (process modelling) and agent based modelling seems to yield a system model that has emergent behaviour that is coherent and similar to that of the real systems.

A top-down and bottoms up cycle is used to link functionality required with known technological constraints or parameters. By “stretching” the ability of the technologies or the doctrine or both, better fit with the stated needs can be demonstrated. From the perspective of the discipline of Systems Engineering, this is a promising result, because once the functional description of the system emerges, classic processes can be used to develop the requirements and to turn out feasible solutions. Once this is done, it is possible to procure systems off the shelf or to develop custom modifications to fit with a local requirement.


Although it is not possible to develop absolute models of complex systems, it is still possible to develop a range of models that will allow the systems engineer to gain the upper hand in the design and delivery of real working systems. The new understanding about the nature of socio-technical systems can be used in this endeavour. I argued that proper contextualization and boundary setting is a critical pre-condition for success. Too often the pressure is there to start from the current technology base and building blocks, with the result that more of the same, and mostly off-the-mark solutions are delivered. The expectations that more smart systems will be developed to support humankind, will grow. With it the tools and approaches have to develop rapidly to take the new reality into account.

Complexity theory is generating increasing interest amongst strategic thinkers. This fascinating book covers issues such as predictability, creativity and relationships as it considers how complexity, and its central principles of emergence and self-organization, are being used to understand organizations. The book:

  • introduces the variety of views put forward by different writers on complexity and management
  • outlines and critiques the way that complexity theory is frequently interpreted purely in the context of systems thinking
  • draws a new perspective on using complexity sciences to understand organizational stability and change by focusing on the emergence of novelty and creativity in the course of everyday processes
  • calls for a radical re-examination of management thinking.

Timely and controversial, Complexity and Management is essential reading for anyone interested in strategy, systems thinking, organization and management theory, and organizational change.

Process Improvement and CMMI® for Systems and Software

Ron S. Kenett, KPA, Ltd., Raanana, Israel;

Emanuel Baker, Process Strategies, Inc., Los Angeles, California, USA

Publisher: CRC Press, March 09 2010

ISBN: 9781420060508

ISBN 10: 1420060503


Presenting the state of the art in strategic planning and process improvement, Process Improvement and CMMI® for Systems and Software provides a workable approach for achieving cost-effective process improvements for systems and software. Focusing on planning, implementation, and management in system and software processes, it supplies a brief overview of basic strategic planning models and covers fundamental concepts and approaches for system and software measurement, testing, and improvements.

The book represents the significant cumulative experience of the authors who were among the first to introduce quality management to the software development processes. It introduces CMMI® and various other software and systems process models. It also provides readers with an easy-to-follow methodology for evaluating the status of development and maintenance processes and for determining the return on investment for process improvements.

The authors examine beta testing and various testing and usability programs. They highlight examples of useful metrics for monitoring process improvement projects and explain how to establish baselines against which to measure achieved improvements. Divided into four parts, this practical resource covers:

  • Strategy and basics of quality and process improvement
  • Assessment and measurement in systems and software
  • Improvements and testing of systems and software
  • Managing and reporting data

The text concludes with a realistic case study that illustrates how the process improvement effort is structured and brings together the methods, tools, and techniques discussed. Spelling out how to lay out a reasoned plan for process improvement, this book supplies readers with concrete action plans for setting up process improvement initiatives that are effective, efficient, and sustainable.

Systems Thinking: A Technique to Find Project Problems

Posted on 16. Jun, 2009 in NETWORK by Bas de Baar

Finding the real cause of a project problem can be a difficult task. You have to look for patterns …

“These patterns are dynamic systems in action, a human system seen over a time period. Patterns are trends over time and involve dependencies with other systems. To spot such trends in projects we use metrics as indicators. If I have the right metrics I can ignore everything around me and focus just on the dashboard.”

A technique that can be used to find patterns and the real cause-effect-chains in projects is systems thinking. “Systems Thinking” is one of the 5 disciplines described in the famous book “The Fifth Discipline” by Peter Senge (for an overview view my posting “Fifth Discipline: What To Do When All Your Projects Are Failing“).

This is the first post in a series that will describe this technique and how to use it in your projects.

Tutorial: Architectural Rendering with ISO/IEC 42010

At 4th European Conference on Software Architecture

August 23, 2010, IT University of Copenhagen, Denmark

IEEE Standard 1471, Recommended Practice for Architectural Description of Software-Intensive Systems, was published in 2000 as the first standard aimed at architecture description. In 2007, it was adopted by ISO and since then has been jointly updated by IEEE and ISO as ISO/IEC/IEEE 42010, Systems and software engineering — Architecture description.

This tutorial introduces the key concepts and mechanisms of the newly revised standard, in the context of practical approaches to architectural rendering of software-intensive systems.
