Computer solutions of linear programming problems are outlined. Information covers vector spaces, convex sets, and matrix algebra elements for solving simultaneous linear equations. Dual problems, reduced cost analysis, ranges, and error analysis are illustrated.
An evaluation of methods for emergency rescue of space crews using the Earth Orbit Shuttle was conducted. Emergency situations were analyzed for the mission categories of extravehicular activity, space shuttle orbiter, space station, and research applications module (RAM). Five different transfer concept categories were analyzed and each was scored on the basis of its operational effectiveness. A cost analysis of the transfer operations was developed.
A guide for coding the Dynamic Operational Requirements and Cost Analysis Program (DORCA 2) is presented. The manual provides a detailed operation of every subroutine, the layout in core of the major matrices and arrays, and the meaning of all program values. Flow charts are included.
