Cost Model Extensions to Support Systems Engineering Cost Estimation for Complex Systems and Systems of Systems

چکیده
Considerable work has been done in the areas of software development, systems engineering, and Commercial Off-the-Shelf (COTS) integration cost modeling, as well as some preliminary work in the area of System of System Engineering (SoSE) cost modeling. These cost models focus on the engineering product, the processes used to develop the product, and the skills and experience levels of the technical staff responsible for the development of the product. The nature of complex systems and systems of systems (SoS) is that they are often composed of many subsystems, some relatively simple and others rather complex. The Constructive Systems Engineering Cost Model (COSYSMO) is a calibrated cost model that most closely estimates the systems engineering effort associated with these complex systems and SoS engineering activities. However, the current version of COSYSMO only allows the user to characterize the system using a single set of parameters, with no ability to generate multiple characterizations for the various subsystems comprising a complex system or SoS. This paper presents an extension to the COSYSMO cost model that allows a user to characterize multiple subsystems within a complex system or multiple systems within an SoS and illustrates how this can be applied to an example SoS.

Neural networks were used to estimate the cost of jet engine components, specifically shafts and cases. The neural network process was compared with results produced by the current conventional cost estimation software and linear regression methods. Due to the complex nature of the parts and the limited amount of information available, data expansion techniques such as doubling-data and data-cr...
