A cost effectiveness study for the selection of a standardized memory system for space and airborne digital computer

Includes bibliographical references (page 65)A cost effectiveness study is made on three of the most promising candidates for a standardized memory system which could be used with a large variety of new and yet to be developed space and airborne computers. A description of the three candidates:\ud A 16K/24 Bit 3D-3 Wire Core Memory System\ud A 16K/24 Bit 2 1/2D-3 Wire Core Memory System\ud A 16K/24 Bit Plated Wire Memory System,\ud and the major design variables of each is presented. Design criteria, threshold levels, weightings, and states of nature were identified and evaluated using Delphi method. The utility function associated with each of the design criteria and the probability that each candidate will achieve specified levels of each criteria is similarly evaluated. The results of the cost effectiveness analysis lead to the selection of the 3D-3 wire core memory design with a relative utility value of 1100, compared to a utility value of 973 for the 2 1/2D-3 wire core memory and a value of 796 for the plated wire memory. A sensitivity analysis reveals that the storage capacity and the power dissipation as the two parameters most likely to affect the decision
