DEVELOPMENT OF COST EFFECTIVENESS ALLOCATION PROGRAMS. MODEL AND OPTIMIZATION TECHNIQUE EXTENSIONS.
Abstract
The results of the second task concerning an investigation of optimization techniques in connection with the Navy Systems Performance Effectiveness program are presented. The approach of the investigation has been first to develop computer programs for solving simple problems and then to generalize the capability for solving more of the problems of interest. Under the first task two programs were prepared. These are: Reliability Cost Trade-off Analysis (RECTA), which is based on a direct search approach, and Separable Integer Program (SIP), which is based on the dynamic programming principle. Under the second task preparation and plans were made for programming modifications and improvements. A major modification to RECTA is a computerized search for the optimal weights on constraint functions and to SIP is to generalize the program for objective and constraint functions which are not completely separable. The Lagrange multiplier technique is to be incorporated into both RECTA and SIP, and both programs are to be modified to facilitate the handling of user-specified objective and constraint functions. A total lifetime cost model for the allocation problem of interest is structured, and the presentation includes relevant highlights of engineering economy on which the model is based. Effectiveness models are identified which are additional to the reliability models used in RECTA and SIP. Models are included for availability, reliability with repair, availability and reliability, and three-state reliability. (Author)
