[Abstract]:With the aggravation of market competition, the traditional paver assembly mode can not meet the market demand. Based on the investigation and analysis of the assembly line of a certain company's wheeled paver, this paper points out the main problems existing in the assembly of the paver in the company, and proposes to adopt the assembly line to assemble the paver. In order to improve the production efficiency of paver, this paper mainly studies the balance of assembly line and layout planning of new workshop. Firstly, the assembly line of wheeled paver is preliminarily planned according to its structural characteristics and technological process. On the basis of analyzing and studying the balance problem of paver assembly line, four kinds of assembly line balance schemes are obtained by using linear programming method, branch and bound method, heuristic algorithm and genetic algorithm to study the balance problem of new assembly line of paver. Secondly, the four assembly schemes are modeled and simulated by eM-Plant simulation software. By comparing and analyzing the balance index and simulation data of the four schemes, it is concluded that genetic algorithm is the first choice algorithm to optimize the balance of paver assembly line. The validity and universality of genetic algorithm in solving assembly line balance problem are verified by a classical example. Finally, according to the shape, size and technological process of the paver assembly workshop, the layout planning of the new workshop is carried out, and three workshop layout schemes are obtained. Analytic hierarchy process (AHP) and AHP- fuzzy comprehensive evaluation method are used to evaluate and select the three layout schemes. The paver assembly line studied in this paper can not only improve the production efficiency of enterprises, but also find a way to solve the problem of assembly line balance of large-scale construction machinery and equipment. It has certain reference significance to the future research similar to the paver assembly line balance problem.
