CRITERIA FOR VALUE ENGINEERING
Abstract
Engineering techniques for broadening the scope and improving the effectiveness of existing conventional value analysis are investigated. Present value analysis practices consist of re-evaluation of product functions and remedial redesign to effect reduction in product acquisition cost. What is desired is a method for quantitatively expressing value and therefrom formulating an engineering procedure for achieving high levels of value, exercising positive value control, promoting value assurance, and accomplishing cost avoidance from product inception through its operational life cycle. In general, the major objectives were realized. Value is expressed in a manner compatible with the dimensionality of other essential systems engineering parameters. The total resource cost criterion is introduced as an optimizing parameter to permit either optimization of performance with maximized cost or optimization of cost factors with minimum acceptable levels of performance. A mathematical modeling technique is provided to facilitate performance/cost optimization by permitting the evaluation of proposed system design-support alternatives and the identification of the least-cost alternative. The mathematical model operates as a difference equation on quantitative reliability, maintainability, operational readiness and total cost factor inputs. Hence, by the selection of the least-cost alternative, a margin of assurance is provided that performance parameter requirements, as well as function, and total cost have been evaluated. The technique was exercised on a hypothetical system illustrating the mechanics of technique application.
