| This paper summarizes the research results of production line balance and production sequencing at home and abroad.By using traditional industrial engineering method and Flexsim software simulation method,the multi-variety valve production line of WD Company is optimized,and good results have been achieved,and the efficiency and output of E8 production line have been improved.Firstly,this paper briefly introduces and summarizes the literature theory of production line balance and production sequencing,and introduces in detail the definition,related concepts and evaluation system of production line balance;the content of traditional industrial engineers on Method Research and job analysis;the concept of Flexsim software,related terms and interface composition.Based on the author’s internship experience in WD Company,the E8 production line of the company is described about the B-type multi-variety valve production line,and the optimization of the production line in this paper is put forward.Then,the traditional industrial engineering method is used to balance the production line operation time.By determining the standard time to calculate the production balance rate,the bottleneck process is found out.Man-machine operation analysis method,model method and process method are used to improve,shorten the production cycle and achieve the goal of balancing the production line.Subsequently,in order to further increase production,this paper first excludes the ineffective production time,constructs the E8 production line model using Flexsim software,and simulates 30 production schemes of E8 production line’s multi-variety valves under the restriction of common production batch conditions,and obtains the final results by combining the waste rate of three products of B type,and follows the comparison.The best principle is the best choice.Finally,the production simulation of forging,heat treatment and inspection stage is carried out to verify the rationality of the optimal production plan.In this paper,the traditional industrial engineering method and Flexsim simulation method are used to improve the production line balance and production scheduling of WD Company.The research results show that the research methods in this paper have a certain reference value in solving similar production line optimization problems,and have a good effect on improving enterprise production efficiency and industry competitiveness. |
