Abstract

The invention relates to the technical field of automatic processing, provides an improved process sequence time-selection comprehensive scheduling method, and provides an improved process sequence time-selection comprehensive scheduling algorithm for solving the problems that when an existing process sequence time-selecting comprehensive scheduling algorithm is used for processing a comprehensive scheduling problem, the solving process is tedious, and operation redundancy occurs. According to the algorithm, when a process sequence time selection strategy is used for determining a process scheduling scheme, the process does not need to be subjected to trial scheduling on all quasi scheduling time points sometimes, the process scheduling scheme can be obtained only by performing trial scheduling on part of quasi scheduling time points, and a result is the same as a result obtained by the process sequence time selection strategy. According to the algorithm, on the premise that the optimization effect of the algorithm is not reduced, the scheduling frequency is reduced, the algorithm complexity is reduced, and the algorithm performance is improved.

Description

technical field [0001] The invention relates to the technical field of automatic processing, in particular to an improved method for timing comprehensive scheduling of process sequences. Background technique [0002] Industrial automation is a general term for information processing and process control such as measurement and manipulation according to the expected goals without the need for direct human intervention by machines and equipment or production processes. Automation technology is to explore and research the methods and technologies to realize the automation process. It is a comprehensive technology involving mechanical, microelectronics, computer, machine vision and other technical fields. The industrial revolution was the midwife of automation technology. It is precisely because of the needs of the industrial revolution that automation technology broke through the egg shell and developed vigorously. At the same time, automation technology has also promoted the...
