Problems solved by technology

However, this kind of multi-model and multi-color car mixed line production will also cause problems such as low production capacity, unbalanced production load, increased production cycle, and increased cost. The reason is that the lack of reasonable production schedules causes frequent spraying of colors in the paint shop. A series of problems such as transformation, unbalanced load in the assembly shop, etc.

Embodiment Construction

[0041] The present invention will be further described in detail below in conjunction with the accompanying drawings and examples of implementation.

[0042] Such as Figure 1-Figure 2 As shown, a multi-rule-constrained production schedule is specifically aimed at the vehicle industry, where multiple varieties are produced on the same line. Sort the problem. Include the following steps:

[0043] Step 1: Initialize the constraints that affect production scheduling as a rule set composed of a series of production rules, expressed as where R i Production rules are divided into the following types: delivery date priority rules, color concentration rules, color distribution rules, model concentration rules, model distribution rules, high, medium and low configuration distribution rules, engine concentration rules, engine distribution rules, gearbox concentration Rules, gearbox distribution rules, load balancing rules, logistics consumption leveling rules;

[0044] Step 2: Acc...

Abstract

The invention relates to a production scheduling method with multi-rule constraints, in particular to a vehicle industry, multi-species collinear production, in order to ensure on-time delivery, reduce painting replacement frequency of a painting workshop, improve load balance of a general assembly workshop, and arrange orders to be scheduled. The steps are as follows: Step 1: Initializing; 2, decomposing the order to be scheduled; 3, generating a welding shop production plan based on constraint rule; 4, generating a painting workshop production plan according to that result of the step 3 andthe constraint rule of the painting workshop; 5, generating a general assembly workshop production plan according to the result of the step 4 and the constraint rule of the general assembly workshop.The invention can effectively solve the problems of frequent change of painting colors, unbalanced load in the general assembly workshop, reduced production capacity, high spraying cost and high production efficiency caused by non-sorting in the production of mixed lines in the whole automobile industry.

Description

technical field [0001] The present invention relates to a multi-rule-constrained production schedule, which is specifically aimed at multi-variety collinear production in the production process of the vehicle industry, lack of a reasonable production schedule, frequent changes of spraying colors in the painting workshop, and unbalanced load in the assembly workshop, etc. series of questions. Background technique [0002] my country's vehicle industry adopts a mixed-flow assembly line production model, that is, the same production line can produce vehicles of various models and colors. This production model can well adapt to the market environment of the vehicle industry: various varieties, small order batches, and tight delivery dates. This model can effectively enhance market competitiveness and strive for more market share. However, this kind of multi-model and multi-color car mixed line production will also cause problems such as low production capacity, unbalanced prod...
