Embodiment Construction

[0040] Now in conjunction with embodiment, accompanying drawing, the present invention will be further described:

[0041]In the method of the present invention, a three-layer distributed negotiation scheduling system of intra-autonomous group scheduling-inter-autonomous group scheduling-conflict arbitration is established to resolve resource conflicts in the scheme. First, the resource agent randomly generates several feasible plans and sends them to the user. At the same time, the user agent independently selects the processing time of its workpiece on each resource according to its own goals; The goal is to score each plan and feed back the scores to the resource agent. The resource agent calculates the score of each plan according to the score fed back by the user agent and the weight of each user agent, and selects the plan with the highest score as the initial plan; the resource agent The initial scheme is adjusted and updated according to the matching results of the use...

Abstract

The present invention relates to a segmented coordination optimization method for multi-agent scheduling. First, the resource autonomous agent randomly generates several feasible solutions and sends them to the user. Self-selection; after receiving the proposals, the user subjects score each plan according to their own goals and feed back the scores to the resource subjects. Score, select the scheme with the highest score as the initial scheme; the resource agent adjusts and updates the initial scheme according to the matching results of the user's self-agent whose initial scheme score is lower than the threshold, and makes it the current scheme. Conflict detection is performed on the current scheme. If there is no conflict, the scheduling is completed; otherwise, intra-autonomous group scheduling is performed.

Description

technical field [0001] The invention belongs to the field of production scheduling, and specifically relates to a segmented coordination and optimization method for multi-agent scheduling. Background technique [0002] The document "Multi-agent single-machine scheduling problem based on combined auction. Computer Integrated Manufacturing System, 2013, 19(1): 106-113." discloses a multi-agent scheduling mechanism based on repeated bidding combined auction. This mechanism combines the general form of combinatorial auction with the modeling technology of machine scheduling, and establishes a multi-agent scheduling model based on combinatorial auction to schedule and allocate resource occupancy time. Use the bidding mechanism, adjust the arrival time and delivery period to coordinate the conflict in the scheduling process. To a certain extent, the utilization efficiency of the machine is improved, and the customer satisfaction is improved at the same time. However, when this m...
