ALGORITHMIC MAINTENANCE OF WKS SUPPORT FOR VOLUME SCHEDULING IN PIPE PRODUCTION

Abstract

Approaches to solving the central problem of the highest hierarchical level of industrial complex management system are conside red. This is the problem of choosing the strategy of volume schedu ling (VC) of pipe production: production to the “warehouse” or production “order”. Each strategy can be characterized by the specific risks of expected revenues losses. The solution of the procedure of forming the optimal structure of the production program (portfolio of orders) is presented. Adequate implementation of this procedure signifi cantly aff ects the performance of the pipe business. This applies primarily to the shops with the multiproduct production of cold deformed pipes. Production logistics in such shops is based on the use of various combinations of technological routes (rolling, broaching, heat treatment, chemical treatment, etc.). The solution was implemented in the form of multicriterial selection process. Decrease in the dimension of optimization problems of VC was implemented using techniques of assortment aggregation of the pipe shop. The technique is based on the algorithm of the synthesis method of principal components factor analysis and automatic classifi cation. Coordination of the production process and the departure sequence of finished products to custo mers were made via an interactive multicriteria iterative procedure. The author has used the method of interval estimation of the substitution criteria, adequate to functionality of the actual users of the services that does not have special training in the theory of decision making.
