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]

[0102] In the formula, CP j Indicates the available...

Abstract

The present invention proposes a product combination optimization problem-solving method based on redistribution of remaining capacity. The principle of the method is to assume that after prioritization, the product sequence is 1, 2,...i, i+1, i+2,. .., n. Then allocate bottleneck resources to products according to the order of priority, and calculate the quantity of each product. During the calculation process, if the quantity of product J is a decimal, you can request resource processing J from a certain product X(i) in front of it, so that Obtain a better product mix solution. Adjusting the existing product mix according to this adjustment plan has advantages over the traditional TOCh method and the revised TOCh method in some cases. It can effectively reduce the waste of enterprise resources, increase enterprise income, and increase the effective output of enterprises.

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...
