Station balance design method of aero-engine general assembly pulse assembly line

Abstract

The invention relates to a position balance design method for an aero-engine final assembly pulsation assembly line, which comprises the following six steps of: inputting a balance process condition of the aero-engine final assembly pulsation assembly line, setting and verifying an operation arrangement rule, encoding a particle swarm, decoding the particle swarm, dynamically constructing a directed acyclic network diagram module, and carrying out reverse differential evolution on the particle swarm. Through a mutation operator, a crossover operator, a selection operator and a reverse transition operator, in combination with population evolution state monitoring and disturbance application, the particle swarm is iteratively evolved in a high-dimensional solution space, and an optimal solution is finally found. According to the method, the design complexity of the aero-engine pulse movement assembly production line is reduced, optimal operation distribution of all the assembly stations is intelligently achieved, the method adapts to the situation that parallel operation and procedures in the stations have constraints on the distributed stations, meanwhile, the maximum takt of operation of all the stations is minimized, total duration balance is considered, and the production efficiency is maximized.

Description

technical field [0001] The invention relates to a station position balance design method of an aero-engine general assembly pulsation assembly line, which belongs to the technical field of design of an aero-engine general assembly production line. Background technique [0002] There are various types of assembly lines, which can be divided into continuous mobile type and pulse mobile type according to the continuous degree of production process. In the continuous mobile upper assembly line, the product is continuously carried out between the processes from input to output, without waiting and interval time. Assembly lines are generally used for mass production and are a relatively complete form of organization. The necessary condition for organizing a continuous assembly line is that the process is mature and stable, and the processing time of all processes is equal to the takt time or an integer multiple of the takt time, so the production organization is difficult; Equal...

[0031] The present invention is designed to provide a station balance design method for the pulsating assembly line of the general assembly of the aero-engine just aiming at the above-mentioned existing technical conditions. The manual calculation is very complicated and the total load balance of the station operation is difficult, especially the hardware facilities have been installed in place, and the assembly process needs to be distributed to each station, so as to reduce the complexity of the station balance design of the aero-engine pulse mobile assembly production line, Intelligently achieve the optimal assignment of each assembly station operation, and at the same time balance the total operation time of each station to maximize production efficiency
