Abstract

The invention discloses a discrete procedure inserting and dispatching method in mixed line production, belonging to the fields of modern manufacturing integration technology and automation. The method comprises the following steps of in each idle time of a processing queue on selected processing equipment, selecting an idle time longer than processing time needed by a procedure to be inserted; selecting an idle starting time nearest to a preset insertion time of the procedure to be inserted from the idle time; comparing the idle starting time of idle time with the insertion time; and continuously advancing the insertion time of the procedure. Therefore, the flexibility of discrete production and the efficiency of important part flow production are ensured, the compatible contradiction of the flexibility of discrete production and the efficiency of important part flow production in workshop production is eliminated, production task due date can be ensured, flow and discrete mixed dispatching is realized and the needs of a workshop mixed operation mode is satisfied. After discrete procedure inserting and dispatching algorithm is used, the whole equipment utilization ratio in mixed line production is promoted.

Description

field of invention [0001] The invention relates to a method for inserting and dispatching discrete processes in mixed-line production, which belongs to the field of modern manufacturing integration technology and automation. Background technique [0002] As the current enterprise production mode is gradually transformed into a form of multi-variety variable batches, the phenomenon of shared resources between research and batch products has arisen, which has led to the pursuit of efficiency in the production of batch products and the production of research and development products. The problem of contradiction between the flexibility sought. In order to effectively resolve this contradiction, a mixed-line production model of flow and discrete production can be adopted, thus resulting in a job-shop scheduling oriented to the mixed model of flow and discrete production. [0003] The job scheduling of the so-called flow-discrete mixed mode is mainly reflected in the mixing of f...
