Batch processing pipeline performance evaluation method

Abstract

The invention provides a batch processing pipeline performance evaluation method. The method is used for evaluating batch processing pipeline average output and each buffer zone level and like indexes; the main existing problem of the batch processing pipeline performance evaluation problem is as follows: the solution of single machine+ batch processor two-machine precise model and the establishment of a batch processor pipeline decomposition equation. The specific process of the invention is as follows: 1, obtaining the precise solution of the two machine models of single machine+ batch processor and single machine+ single machine; 2, decomposing the pipeline containing multi-machine into a plurality of building blocks containing two-machine single-buffer, and establishing the decomposition equations aiming at the building blocks; 3, solving the equations through an iterative method (PDDX method), and finally obtaining the performance index of the pipeline: production yield and number of work in process; 4, performing numerical contrast through summation simulation result to verify the rationality of the method provided by the invention.

Description

technical field [0001] The invention relates to the field of performance evaluation of a production system, in particular to a method for evaluating the performance of a batch processing pipeline, which is used for evaluating the average output of the batch processing pipeline and each buffer level index. Background technique [0002] Rigorous performance analysis, continuous improvement and lean design of the production system can bring great economic benefits to the enterprise, and the research is of great significance. A lot of research results have been obtained on the performance evaluation of pipeline systems with unreliable machines and limited buffer capacity buffers. These studies usually assume that a machine can only process one workpiece at a time. In actual situations, there is also a situation where one machine needs to process one batch at a time, that is, multiple workpieces. For example, in the process of gear manufacturing, after milling and grinding, heat...

Problems solved by technology

[0003] Both analysis and simulation methods can evaluate the production system indicators, but the simulation method can only face a specific problem, does not have general versatility, and is costly and time-consuming; while the analysis method can face the same type of problems and can Provide a more consistent solution
