An Exploratory Prototype for Reactive Management of Aeromedical Evacuation Plans.
Abstract
This report summarizes the results of an initial, four month project demonstrating the applicability of the DITOPS scheduling system to USTRANSCOM's Aeromedical Evacuation (MEDEVAC) re-planning problem. DITOPS is an advanced prototype system developed at Carnegie Mellon University for development, analysis and revision of large-scale schedules, applied originally to the logistics domain of strategic deployment. DITOPS implements a reactive, constraint-based approach to scheduling, providing techniques and system architecture for efficient, localized revision of plans/schedules in response to changed constraints or decisions. Using DITOPS, a prototype medical evacuation replanner has been designed and implemented for comparison with Carnegie Group's TRAC2ES reactive planner module. From a system development perspective, DITOPS is a toolkit and a class library for configuring planning and scheduling applications; the approach to application design and construction relies on object-oriented programming techniques and software reuse, allowing applications to be constructed as a 'differential' process, focusing primarily on the differences between existing software and the system being constructed. During this project, the medical evacuation domain was modeled using the core modeling primitives available in DITOPS, and rescheduling techniques were developed for responding to common med- medical evacuation replanning problems, again using existing components from DITOPS.
