Extension Transformation Based On Single And Small Batch Of Large-scale Manufacturing Enterprise Problem Fixed Working Hours

Since the beginning of the new century, the global economy has developed rapidly. Thecountries of the world economic and market environment has greatly changed. With theincreasing customer diversity, individual needs, many enterprises have adopted the custommode of production. Single-piece, small batch production strategies used in suchcircumstances is of such enterprises play a very important role. The variability due to therandomness of the orders, the diversity of products, processes, and which to the enterprise inthe development of working hours, working hours costing enormous pressure. When thehour establishment is not quite rational enough science, this to the enterprise in theproduction procurement, production planning, product delivery bring great trouble, not onlymake the enterprise production efficiency is low, the enterprise management level is nothigh, more important is to be able to enable enterprises to gradually lose market competitionability. Therefore, for large single and small batch production-oriented enterprises in theprocess of when to improve the management level of production to meet the demand ofmarket diversification, improve production efficiency, product man-hours to develop thescientific rationality become critical.This article is the basis for the study of fixed working hours in single and small batchdesign and manufacture of relevant theory and industrial engineering-oriented theory.Existing fixed working hours is inadequate, combined with the principle of similarity of theproducts and the product structure tree thinking. Propose a new method for timequota-oriented product structure-product structure fixed method, referred to as the PSN Act（Product Structure Norm）. First, the method relies on the design and manufacture of singleand small batch basic theory of the structural unit of all levels to redefine and rely on a newdefinition of the structure unit was constructed based on the structural model of the method;Again, the method to use when the use of extenics theory and extension of primitive theory,various structural units of extension to describe the hierarchical relationships between thevarious structural units by the description of the primitive expression; Third, the use ofprimitive theory of extension transformation and combination of Industrial Engineering testmethod to establish a set of structural units of time solving techniques, and successfulindividual structural units of time to get the fixed time method and the working hours of thefinal product; Finally, in order to make the method can be efficient implementation,combined with the similarity of large-scale and small batches of products, the proposedaccess and reuse historical data, combined with a related method to develop a structural unittime historical time data reuse and revision process and methods.Finally, A enterprise fixed working hours, investigation and analysis of the state of theproduction. A enterprise application implementation time quota method proposed in thispaper. The results show that: the methods to get the time date can be the better as a basis forA company to develop fixed working hours. In order to verify the proposed fixed workinghours feasibility and effectiveness. Also provide a reference further research andexploration.
