Assessing the Impact of Development Disruptions and Dependencies in Analysis of Alternatives of System-of-Systems. Phase 1

Abstract

The development of emergent capabilities for a System-of-Systems (SoS) is greatly challenging due to the complex interdependencies between its constituent systems, that often exhibit managerial and operational independence. Current guidelines set forth by the Department of Defense SoS System Engineering guide presents SoS SE as a set of seven core elements which are connected to the 16 technical and management processes in the Defense Acquisition Guidebook (DAG). The DAG and subsequent frameworks (such as the DoD SoSE guide and wave model), are meant as base guidelines in addressing key issues associated with the management and evolution of an SoS gamut. Prior funded work, under RT-36, explored analytical methods to quantify the impact of system interdependencies in the context of SoS capability development and use this to guide system engineering activity for SoS. A variety of approaches were investigated to provide a means to conduct analysis of alternatives while navigating the decision space that simultaneously considers the potential positive impacts of interdependencies (e.g., SoS capability) as well as the negative impacts (e.g. consequences of disruption in development). The work is being continued under this RT-44 initiative, with the end goal of providing an analytical workbench complemented by intuitive and instructive applications on a naval scenario case study. This report details Phase I progress of a (Phase I & II) effort under RT-44 towards the development of a computational analytic workbench. Progress for each of the constituent methods, that comprise the range of tools in the workbench, is presented. Additionally improvements to the Littoral Combat Ship (LCS) inspired Naval Warfare Scenario (NWS) simulation, that serves as our representative SoS problem, is presented as well.
