Problems solved by technology
The traditional production plan selection method usually takes the completion time as the selection standard, and cannot comprehensively consider factors such as economy and applicability. However, through the production plan evaluation method, the comprehensive evaluation of each production plan can be realized, thereby helping enterprises to realize multiple production plans. Therefore, there is an urgent need for an evaluation index system and evaluation method for discrete workshop production planning

Embodiment example
[0167] The process of a specific embodiment of the present invention will be introduced below in conjunction with a specific case.
[0168] Such as image 3 Shown is the workshop layout of an automated production line for structural parts. This production line is used to process aircraft structural parts. The logistics equipment is manipulators with guide rails, and the processing equipment is 4 machine tools. The numbers are VB-825A#01, VB-825A#02, For VB-825A#03 and VB-825A#04, the buffer equipment is a buffer frame (buffer capacity is 10).
[0169] In order to achieve a certain production target, four samples of production planning and scheduling are obtained according to the production scheduling, among which the sample scheduling of y1 is as follows Figure 4 As shown in (a), the y2 sample schedule is as follows Figure 4 As shown in (b), the sample schedule of y3 is as follows Figure 4As shown in (c), the y4 sample schedule is as follows Figure 4 (d) shown.

The invention discloses a discrete workshop production plan evaluation method based on combined weighting. The method comprises the following steps: 1, building a discrete workshop production plan evaluation index system from three dimensions: economy, timeliness and applicability, obtaining an evaluation index value, and carrying out the standardization processing; 2, performing combined weighting on each evaluation index in the determined evaluation index system through an extension analytic hierarchy process, an improved CRITIC method and an entropy method; 3, constructing a discrete workshop production plan evaluation factor set and a comment set; and taking the obtained standardized index value as a score value, combining the determined index combination weight to obtain a comprehensive score value of each production plan so as to obtain an optimal production plan scheme, and further analyzing the factor set to obtain a key index restricting the workshop comprehensive score underthe optimal production plan. The discrete workshop production plan situation can be comprehensively and scientifically evaluated so that the level of making the production plan by the discrete manufacturing enterprise can be enhanced.
Description
technical field [0001] The invention belongs to the technical field of discrete manufacturing production planning evaluation, and in particular relates to a method for evaluating discrete workshop production planning based on combination weighting. Background technique [0002] Discrete manufacturing represented by manufacturing industries such as aircraft, automobiles, ships, and electronics occupies a large proportion in the development of the national economy. Production planning, as the yardstick for the production and management of discrete manufacturing enterprises, is an important part of the business plan of discrete manufacturing enterprises , is the key to production decision-making, and is of great significance to manufacturing resource allocation and control scheduling decisions. Due to the continuous fluctuation of the external market environment and the increasing pressure of market competition, discrete manufacturing enterprises need to have the ability to qua...
