Abstract

Abstract: In their paper on "A Generalized Systems Engineering Reuse Framework and Its Cost Estimating Relationships, " (Wang, Roedler, et al. 2014) present an approach for estimation of systems engineering effort that extends the COSYSMO equation to account for the effort associated with Design With Reuse and Design For Reuse classification categories in the Generalized Reuse Framework. Implementation of this approach for cost estimation clearly depends on two critical items: (1) the ability to accurately and consistently count the size drivers; and (2) the ability to calibrate the model equation. As part of future work, they also describe the potential to use this approach as a management tool in architecture development – "a cataloging mechanism in organizing components of reference architecture." This paper presents a practical implementation of the COSYSMO cost estimating relationship through extension of a Model Based Systems Engineering (MBSE) modeling environment with SysML for estimating end‐to‐end systems engineering effort in developing a system. The approach provides a new way of rapidly creating cost estimates, conducting cost‐based analysis and trade studies with full traceability from the cost estimation parameters back to the architecture of referenced system of interest.
