7.1.2 System of Systems Engineering Facilitates Integration of Large Scale Complex Systems

ABSTRACT Systems of Systems Engineering, SOSE, is a new field and opens a wide challenge for Systems Engineering researchers who are dealing with large scale complex systems. Integration is one of many tasks required by Systems Engineers who are involved in the process of acquiring a working system that fulfills the main mission of the large scale system. Generally, there are three large scale complex systems cases that need to be integrated: 1) new systems with new systems, 2) old systems with new systems, and 3) old systems with old systems. In the literature, the main focus of the research is on Systems Engineering integration processes for systems which are still under design and before their final phase‐out. This research presents a contribution to define the System of Systems Engineering (SOSE) science through facilitating the integration of two existing large scale complex systems “old system to old system” into one using a simple and clear new process model for integration. One of the reasons for selecting this case is the significant need to integrate “old systems with other old systems”. The integration process has many approaches and models, i.e. V‐Model which is mostly used during the life cycle of building a system. What makes this research unique is the introduction of the “M‐model” that facilitates integration of “existing / old” large scale complex systems with each other. The M‐Model starts with defining the “Problem statement,” then the sequence of building‐up documents and plans leads to a master plan documented called “SOSE Master Plan (SOSEMP).” Some case studies will be discussed.
