The filed of system of systems engineering (SoSE) represents new challenges to both systems engineering and complex systems and related fields like communication, simulation, modeling, control, etc.
In recent years, there has been a growing recognition that significant changes need to be made in American and other nations’ industries, especially in the aerospace, healthcare, and defense areas. Aerospace industry at least in the United States is undergoing a transformation or evolution. Today, major aerospace and defense manufacturers, including (but not limited to) Boeing, Lockheed-Martin, Northrop-Grumman, Raytheon, BAE Systems, etc. all include some version of "large-scale systems integration" as a key part of their business strategies. In some cases, these companies have even established entire business units dedicated to systems integration activities.
System of systems often consists of transformational, network-centric systems with software intensive characteristics. The emphasis is in inter-operability and capability-based systems leading to system of systems configuration. In such emerging applications traditional sequential acquisition approaches are no longer quite adequate. The need for performance optimization among group of heterogeneous systems in order to realize a common objective is becoming the focus of a diverse range of applications including military, security, aerospace and disaster management. There is an increasing need to achieve synergy between these independent systems in order to achieve the most desired overall system performance. A number of recent papers in the literature have addressed the issue of coordination and interoperability in system of systems.
In US Department of Defense (DoD) many efforts are underway to utilize SoS as a technology where national and regional security can best be attained. As an example, in 2005 US Army announced a joint project with Boeing on the creation of the System of Systems Integration Laboratory (SoSIL) in Huntington Beach, CA, where all 18 platforms in the network-centric warfare can be simulated and tested. The facilities will allow soldiers and civilian experts to work together to develop, test and evaluate the future combat systems (FCS) network that connects vehicles and war fighters on the battlefield. The facility will provide a platform, which culminates in a mission test in which soldiers are brought into red and blue forces using the equipment in a simulated battle. Another DoD mandate prescribes use of Department of Defense Architecture Framework (DoDAF) be the common denominator for all DoD net-centric systems. In addition, some fundamental issues related to autonomous operation and collaboration of heterogeneous teams such as path planning, trajectory tracking, communications, resources allocation, task decomposition and allocation, information sharing and cooperative execution are typical examples where SoS theory of modeling and simulation may be successfully applied, where civil or environmental scenarios of coordination and cooperation such as surveillance, search and rescue imply the use of a solid SoS background.
Modeling and Simulation (M&S) is finding increasing application in important aspects of command and control systems comprised of information intensive component systems. One aspect of such application is the incorporation of M&S functionality into such systems which is also an objective of the Extensible Modeling and Simulation Framework (XMSF). Another aspect is the use of M&S to support the development and testing such systems as instances of System of Systems (SoS). The SoS concept relates to the attempt to integrate disparate systems to achieve a specific goal, typically not co-incident with the goals of the pre-existing component systems. Consequently, the defining concern in SoS engineering is interoperability, or lack thereof, among the constituent system. Achieving such interoperability is among the chief SoS engineering objectives in the development of command and control (C2) capabilities for joint and coalition warfare.
In this light, the present author discussed the role that M&S can play in helping to address the interoperability problems in SoS engineering. The present effort builds upon the recent work by the authors published in international journals by considering not only the parallel between SoS engineering and distributed simulation, but also how M&S can be more integrally included within SoS engineering approaches. The focus of this endeavor is to present fundamental concepts to help tackle the integration of M&S and C2 SoS through the use of concepts and standards for interoperability and testing based on the Discrete Event Systems Specification (DEVS) Unified Process as proposed by Mittal in his PhD dissertation and published in C2 Journals and other conferences. Our ultimate motivation is to bring together M&S concepts and technologies to support collaborative decision making in C2 SoS as well as the testing and evaluation of such systems.
As it was mentioned, SoS and SoSE represent new challenges facing engineers and professionals all over the world. The main objective of this book is to put together various methodologies utilizing Modeling and Simulation as an integral part of the SoS lifecyle development. Following are the goals of the proposed book:
- Provide state of the art M&S methodologies in SoS engineering
- Provide both undergraduate and Graduate text in developing M&S-based net-centric SoS.
- Provide foundation of net-centric systems software engineering
- Provide seminal text in the area of Executable Architectures based on Department of Defense Architecture Framework.
