Problems solved by technology

Metaheuristic algorithms commonly used to solve such problems include genetic algorithm, simulated annealing algorithm, tabu search algorithm and ant colony algorithm, etc., but genetic algorithm and ant colony algorithm are prone to shortcomings such as low local search ability and poor convergence in practical applications. The disadvantage of simulated annealing algorithm and tabu search algorithm is that they do not know much about the status of the global search space, and the operation efficiency is low.

[0034] Balance problem description of mixed-flow bilateral assembly line

[0035] The mixed-flow bilateral assembly line balance refers to assigning the task sets of each variety of products to a certain number of workstations under the condition of satisfying various constraints, so that the working time of each workstation is within the set takt time for each variety. Optimize the weighted total cost per unit product, obtain a better task allocation plan, and guide the assembly of large machines.

Abstract

The invention discloses a cost-oriented mixed-model two-sided assembly line balancing method. A mixed colonial competition algorithm is adopted. The method comprises the following steps: empire initialization, intra-empire assimilation, intra-empire updating and colonial competition, colonial reformation and empire cancellation. If the ideal state or the preset number of iteration is reached, a country with the minimum cost is outputted so that a task distribution mode corresponding to the country with the minimum cost is obtained. Compared with a common colonial competition algorithm and a genetic algorithm, the cost value obtained via the method is lower so that algorithm searching performance can be effectively improved and a better solution can be obtained.

Description

technical field [0001] The invention belongs to the technical field of automatic production lines, and in particular relates to a balancing method for a mixed-flow bilateral assembly line. Background technique [0002] The Mixed-model Two-sided Assembly Line Balancing Problem (MTALBP) is an important optimization problem faced by large machine manufacturers such as automobiles and engineering machinery. The mixed-flow bilateral assembly line can meet the diversification of customer needs and reduce the weighted total cost of unit product (WTcost), which can have a direct impact on the economic benefits of the enterprise. The mixed-flow bilateral assembly line is mainly used to assemble different varieties of the same product on the same bilateral assembly line at the same time, so as to realize the diversification of line product varieties and meet the needs of actual production, and there are many similarities between different varieties. It is placed on the same assembly ...
