Toch method for solving single-bottleneck product portfolio optimization problem based on process adjustment

Abstract

The invention provides a TOCh method for solving the problem of single-bottle neck product mix optimization based on process control. The method comprises the steps that first, a system resource bottle neck is recognized, product priority is determined, bottle neck resources are distributed according to the product priority, one more processing mode is provided for solving the decimal solution part in the product combining process, and not only is the mode that fractional part resources are conveyed to low priority products considered, but also the mode that resources are demanded from the previous priority products for rounding is taken into account; the ultimate adopted mode is chosen by comparing the effective output variable quantity caused by the two decimal part processing modes; when effective output loss happens to the two modes, the mode with the small loss is selected; when the fact that resources are demanded upwards can cause effective output increase of the production system, the mode that the resources are demanded upwards is selected for rounding. By the adoption of the method, enterprise resource waste can be effectively reduced, and enterprise incomes are effectively increased.

Description

technical field [0001] The invention relates to the problem of redistribution of remaining capacity in product combination optimization, in particular to a TOCh method based on process adjustment for solving the single-bottleneck product combination optimization problem. Background technique [0002] Product mix optimization (product mix optimization) problem is to determine the product category and corresponding quantity that meet the resource capacity constraints under the given market demand, so as to maximize the system profit. The traditional TOC product mix optimization model is as follows: Assume that the enterprise has m equipment resources and is going to produce n different products. Product i occupies device j for t ij , while the capability of device j is limited to β j , it is necessary to determine the quantity y of product i planned to be processed i , to maximize the total effective output of the system. It should be pointed out that y i Need to meet: ① ...

Problems solved by technology

[0064] In order to solve the inadequacies of the traditional TOCh method and the revised TOCh method in the solution process of negatively discarding the fractional solution part, the present invention proposes a TOCh method based on process adjustment to solve the single-bottleneck product combination optimization problem. High-priority products request resource capabilities, and at the same time re-use the remaining resource capabilities, round up the fractional part of this priority product into an integer, and then obtain the optimal solution for product portfolio optimization
