Strategic Sealift Analysis System (SEASTRAT).
1997
Elwell, Robert G.
The Military Sealift Command, a component of the United States Transportation Command, is responsible for the sealift of military cargo during a crisis. Conceptual plans for these complex moves,called deliberate plans, are continually being prepared. A computer-based scheduling system, the Strategic Sealift Analysis System (SEASTRAT), has been developed to assist in the production of these plans. The ship scheduling portion of this system, the Scheduling Algorithm for Improving Lift (SAIL), combines linear optimization and heuristic methods to determine ship routes and cargo loadings which honor a variety of complex operational constraints. The prototype system was developed in 1986 and the operational model came into operation in 1992, although not all components of SEASTRAT have been developed. Current plans call for SAIL to migrate into USTRANSCOM's Joint Flow and Analysis System for Transportation (JFAST) and for the SEASTRAT at MSC to be terminated. This paper provides a general description of SEASTRAT with emphasis on SAIL and discusses issues related to its planned migration to JFAST.
