Push-type high-efficiency and high-accuracy intelligent production scheduling algorithm and information recording medium

Abstract

The invention discloses a push-type high-efficiency high-accuracy intelligent production scheduling algorithm and an information recording medium, and the algorithm comprises the following steps: (a),obtaining the production related information of a workpiece; (b) defining the states of K semi-finished workpieces; (c) according to the K states of different semi-finished workpieces; (d) judging whether the time is within the range of ST and EN of the corresponding finished product or not; (e) recording scheduling starting time; (f) performing semi-finished product production scheduling according to the starting time; (g) calculating plan end time; (h) judging whether the planned end time is within the range of ST and EN of the corresponding finished product or not; (i) if the steps (d) and(h) do not meet the manufacturing delivery time requirement, providing an alarm and suggestion; and (j) adjusting the scheduling parameters, and returning to the step (a). According to the invention,intelligent scheduling of production work orders is achieved, and the problems of low efficiency, slow period and the like caused by a large amount of manual operation can be reduced.

Description

technical field [0001] The invention belongs to the technical field of production control, and more specifically relates to a push-type high-efficiency and high-accuracy intelligent production scheduling algorithm and a computer-readable information recording medium. Background technique [0002] Production planning is the engine of the supply chain, especially for manufacturing enterprises with the characteristics of single piece, customization, small batch, short cycle, and discrete production mode. Production planning scheduling and adjustment efficiency and accuracy are the core competition for enterprises to improve The research on intelligent production scheduling has become one of the important topics in the development of this type of enterprise. The production plan of manufacturing enterprises with the characteristics of single piece, customization, small batch, short cycle and discrete production mode changes frequently and greatly. In order to pursue a short cycle...

Problems solved by technology

[0003] At present, the production scheduling and production plan management of this type of enterprise mainly have the following problems: (1) The efficiency of production planning and scheduling is low, and the production scheduling needs to manually enter the scheduling start time in the system, and then schedule; (2) Production The workload of plan adjustment is heavy. Due to abnormal production and frequent changes, the production plan needs to be adjusted frequently. It needs to be manually calculated and re-entered to re-enter the start time of the rescheduling of the production work order to be adjusted, and then execute the system scheduling; (3) Manufacturing The simulation man-hour lags behind and the statistical workload is large, resulting in low accuracy of the production plan. Due to the adoption of the agile manufacturing production method, the process preparation, manufacturing simulation, and production planning and scheduling adopt a parallel operation method. Since the manufacturing simulation takes a long time, the actual production The manufacturing simulation in China often lags behind the production planning and scheduling, resulting in that the process man-hours used in the production planning can only be manual evaluation man-hours, and the accuracy is poor; (4) The production planning and scheduling are labor-intensive and have low work added value, and the production planning and scheduling and Adjustment requires manual statistics of the arrival of a large number of procurement plans, actual arrival, process release, production work order completion, etc., and then formulate the start time of the schedule according to the current state of the semi-finished workpiece and execute the system schedule
