Improvement of preproduction machine components on the base of applying formal estimation of similarity project decisions

It is show, that technological design automation systems are system of only operation level, which don’t allow to estimate a similarity of project design objectively. Relevance of the researches directed to identification and use for increase efficiency of preproduction communications and quantitative formal estimates of similarity of constructive and technology project solutions is proved. Scientific and methodical approach to determination and use by quantitative estimates of similarity of constructive and technology project solutions in preproduction machine components is stated. Applications of estimates of similarity of project decisions are specified in preproduction. It is shown that the ratio estimation of similarity of route technological processes structure of production any two details of one group and estimation of constructive similarity on structure of technological complexes of the same details allows to predict the expected values of estimates of technological similarity of the set detail and a detail of an estimated analog. It allows to organize the automated search of the technological processes analogs demanding the minimum adjustment when transforming to single processes of production the set details. Use formally determined according to the offered approach estimates of similarity of constructive and technology project solutions promotes increase in efficiency of preparation of production for the account: directed search of the next processes analogs, objective forming of groups of technologically similar details, objective estimation of technological capabilities of a production system.
