Embodiment Construction
[0026] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the implementation methods and accompanying drawings.
[0027] The present invention adopts the CARVER matrix and the system evaluation method to design the priority rules, then uses the heuristic algorithm to identify the critical chain based on the designed priority rules, and finally completes the buffer setting through the factory physics variability theory and resource utilization measurement. On the premise of ensuring the accuracy of the buffer setting, the multi-objective critical chain production scheduling is realized. Its specific implementation steps are as follows:
[0028] Step 1. Design priority rules.
[0029] 1.1 Set customer importance:
[0030]For the production scheduling of multiple orders, in the case of the same order, the orders of more important customers should be...
