MBSE for Sustainment: A Case Study of the Air Force Launch and Test Range System (LTRS)

摘要

Modelling of large legacy systems in the sustainment and operations phase of the lifecycle can present some novel challenges to Model-Based System Engineering (MBSE) practitioners. These include fractured or missing documentation, heterogenous sets of equipment with varying vintages, diverse nomenclature for the same equipment, and the need for upgrades without affecting current capabilities. This makes managing modernization efforts, performing cyber accreditation, and documenting the current state of the system more difficult. For this paper, we will detail how using MBSE eased these challenges for the Air Force Launch and Test Range System (LTRS). We will describe the methods, results, and lessons learned in development of the digital systems model for LTRS and how the model supported the System Engineering and Integration (SE&I) teams.
