THE CHOICE TECHNIQUE OF OPERATIONAL CHARACTERISTICS IMPROVING METHODS AT THE STAGE OF CONCEPTUAL DESIGN
In this article three stages of the technical device conceptual design are considered. Methods, approaches and systems of processes automation are developed for fulfilling the first two stages. On the third stage a design engineer can use versatile methods or the author’s special generalized methods to improve operational characteristics of the device. Now there is no common choice technology of the generalized methods. This article is devoted to the description of the developed choice procedures of the generalized methods on a final third stage of conceptual design. Two choice procedures are step by step considered: a demand to the improved operational characteristics and patentability of the designed device at the inventive level. At the final stage a design engineer needs to select the most promising generalized methods for further use. Therefore in this article a number of criteria, which allow to assess the chosen method, is developed: a versatility and efficiency index, an average rate of improvement or deterioration level, a number of the improved or worsened characteristics. On the basis of the listed criteria the complex criterion is formulated, it can be used to choose the most effective method of operational characteristics improvement of the technical device.
