Abstract

The invention provides a two-machine assembly line performance evaluation method considering a dormancy strategy. According to the method, before performance evaluation is performed, modeling analysis is performed on a two-machine assembly line considering the dormancy strategy, a two-machine assembly line analysis model considering the dormancy strategy is established, and the two-machine assembly line analysis model considering the dormancy strategy is solved; and then specific steps of the two-machine assembly line performance evaluation method considering the dormancy strategy are given. It can be seen from multiple calculation examples of the embodiment that by the adoption of the method, the performance of the two-machine assembly line considering the dormancy strategy can be effectively analyzed.

Description

technical field [0001] The present invention relates to the technical field of production system modeling and performance evaluation, and specifically provides an analytical method for accurately analyzing a two-machine assembly line considering the sleep strategy by adopting a sleep control strategy, so as to evaluate the effective efficiency and buffer zone of the pipeline Level. Background technique [0002] Production Systems Engineering (PSE) is a recently developed branch of engineering, which aims to use mathematical models to study the basic properties and operating laws of production systems, and use these properties and laws to perform performance analysis, continuous improvement and Lean design. [0003] The research difficulties of production system engineering problems mainly come from the unreliability of the machine and the limited capacity of the buffer zone. Machine failure may block the upstream machine and starve the downstream machine due to no part pro...
