Problems solved by technology

[0062] In order to solve the failure of the traditional TOCh method and the revised TOCh method in the solution process, the present invention proposes a product combination optimization problem-solving method based on the redistribution of residual capacity. This method uses a new residual capacity allocation mechanism to make resource utilization With higher efficiency, better product portfolio optimization results can be obtained than existing heuristic methods, making the effective output of the system larger

Embodiment Construction

[0094] The embodiments of the present invention will be described in detail below, and the described embodiments are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0095] In this embodiment, the enterprise production calculation example still adopts the calculation example described in Table 1:

[0096] Calculation description

[0097]

[0098] For the above calculation example, using the product combination optimization problem solving method based on the redistribution of remaining capacity in the present invention includes the following steps:

[0099] Step 1: Identify system bottleneck resources:

[0100] For resource j, j=1,2,...,m, m is the number of resources in the system; calculate the difference d between the required capacity and the available capacity j , if d j <0, resource j is considered to be a bottleneck resource:

[0101] d j = ...

Abstract

The invention puts forward a surplus capability redistribution-based product combination optimization problem solving method which is based on a principle that a product sequence is 1, 2, . . .i, i+1, i+2, . . ., n according to priority ranking is assumed. Bottleneck resources are distributed to products according to the priority ranking, and quantities of all products are calculated; if products J are small in quantity in calculation processes, resources can be requested from preceding products X (i) to process products J, and therefore a good product combination solution can be obtained. Compared with a conventional TOCh method and a revised TOCh method, an adjustment solution via which existing product combinations are adjusted is advantageous in that enterprise resource waste can be effectively reduced, enterprise income can be increased, and effective output of an enterprise can be improved.

Description

technical field [0001] The present invention relates to the technical field of product combination optimization, specifically a method for solving product combination optimization problems based on the redistribution of remaining capacity, through the processing of remaining capacity, the traditional TOC (Theory of constraints bottleneck theory) product combination problem can be obtained Optimal or optimal solution. Background technique [0002] Product mix optimization (product mix optimization) problem is under the given market demand, how to configure the product types and corresponding quantities that meet the constraints of resource capabilities, so as to maximize the system's profits. The traditional TOC product mix optimization model is generally expressed as: 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 CP j , it is necessary...
