Serial production line buffer zone capacity allocation method based on availability evaluation

Abstract

The invention relates to a serial production line buffer zone capacity allocation method based on availability evaluation. The serial production line buffer zone capacity allocation method specifically comprises: 1) determining the number of serial production line devices and the total capacity of buffer zones; 2) decomposing a serial production line into a plurality of secondary subsystems; 3) determining the state law of secondary subsystem devices; 4) determining the change law of the states of buffer zones of the secondary subsystems; 5) determining an availability evaluation model of thesecondary subsystems; 6) making the secondary subsystems equivalent to a virtual device, and forming new secondary subsystems; 7) performing multiple iterations to determine the availability evaluation model of the serial production line; and 8) using the improved genetic algorithm to solve the model. The invention can reasonably allocate the capacity of the buffer zones of the serial production line and improve the productivity of the serial production line.

Description

technical field [0001] The invention relates to the field of industrial production, in particular to a method for configuring the buffer capacity of a serial production line based on availability evaluation. Background technique [0002] The determination of the buffer capacity in a serial production line will greatly affect the production efficiency of the entire production system. At present, there are still major problems in the design of serial production lines in some industries in our country. There is no scientific theoretical support, and only relying on the experience of designers, the production efficiency of the production line has great room for improvement. If the buffer capacity in the production line is set too small, the upper and lower level equipment will start and stop frequently, which will not only cause unnecessary waste of electric energy, but also greatly reduce the production efficiency; if the buffer capacity in the production line is set too large,...
