Embodiment

[0093] Let: n be the total number of T beams to be processed, Y and Z respectively represent the length and width of the workshop, J is the total number of production lines, and I is the total number of processes.

[0094] It is assumed that the production of T beams in this embodiment has three processes of ABC, the production workshop has four production lines of A, B, C, D, and 7 pieces of T beams to be processed. That is, in this embodiment, the T beam production is divided into three processes, and the three processes are respectively expressed as process A, process B, and process C according to the processing order.

[0095] Step 1: Establish the objective function

[0096] The objective function is:

[0097] MIN(Tn)=min(max(t fjik ) 1≤j≤J,1≤i≤I -min(t sj11 ) 1≤j≤J,1≤i≤I ) (1)

[0098] Among them, n represents the total number of T beams to be processed, J represents the total number of T beam production lines, and I represents the total number of processes on the ...

Abstract

The invention provides a T-beam production control method and system, and the method comprises the steps: taking each process on a T-beam production line as an independent individual to combine a T-beam processing sequence, and calculating the processing period of each combination in combination with a processing constraint condition, thereby obtaining the shortest processing period as the shortest construction period of a T-beam workshop, and enabling the production of T-beams to be more efficient. According to the method, the T-beam working procedure combination is updated based on the sine and cosine algorithm, the accuracy of solving the shortest construction period of the T-beam workshop is further improved, and the calculation convergence speed is increased.

Description

technical field [0001] The invention relates to the field of workshop scheduling, in particular to a T beam production control method and system. Background technique [0002] The large-scale job shop scheduling problem is an important branch of the job shop scheduling problem. However, the traditional job shop scheduling problem only considers the limitations of the processing process, and cannot linearly optimize the large-scale workshop process sequence according to the factors that affect each process on the workshop production line. The optimization of the T beam production period is not ideal. SUMMARY OF THE INVENTION [0003] In order to solve the above-mentioned defect in the prior art that the T beam production period is not optimized according to the specific conditions of the T beam production workshop. [0004] The invention provides a T beam production control method, which can calculate the T beam production cycle corresponding to different process combinati...
