Shoe Companies Forming Production Line Balance Research

The background of the effects of mass production in the standard,application of production line in manufacturing industry. Product line has become more and more widely.As an important form of production line manufacturing industry production,the balance or not, has a crucial impact on the enterprise. Production line balancing work load will lead to the operators not balanced, WIP, low productivity and product quality is not stable and so on a series of problems. So the study of assembly line balancing problem, it is particularly important to pay attention to the efficiency and productivity of the manufacturing industry.Based on the summary and analysis of domestic and abroad in recent years on the production line balancing problem solving methods, combined with their own practice in the enterprise. In the production line of A company as the research object, the use of industrial engineering is the analysis and Research on the related theory and technology, a 0-1 integer programming model is built, and the use of Lingo software to solve. In molding production line balancing problem of A company to improve, and achieved good results.First of all, through on-site observation, field measurement, image observation and analysis,data analysis of the production process on the production line of A company analysis. Based on the analysis of the forming process, combining with the analysis method of industrial engineering, the whole process of molding production line. Aiming at the existing problems of the production line and puts forward suggestions for improvement. Secondly, the smallest unit of work division, the use of each operation unit was analyzed by MTM software, standard working time of each operation unit. Finally, a 0-1 integer programming model is built in the first class,molding production line A,class II production line balancing,production and programming by Lingo software, the optimization of two kinds of production line balancing problem solution, the optimized results and improvement of production line before the ratio analysis. The main research results of this paper are:(1) through the study of recent years about the problem of assembly line balance theory and the method of comparison and analysis, choose a kind of method is more suitable for small and medium-sized enterprises to solve the problem of assembly line balance.(2) the time of process operation unit of A company in the production line, standard working time to set the minimum unit of work through the introduction of MTM software. At present, in the small and medium-sized enterprise by using the software of MTM to standard operation time is relatively small.(3) taking A company as an example, this paper provides a set of more perfect to solve the problem of assembly line balance solution for A company.In this paper,through the use of the theory of industrial engineering and technology,this paper, improves the A molding production line workers working environment, reduce the operator’s work load, optimizing the production process of the whole production line,not only improve the line balance rate,and improve the management level of the production site,provides a set of execution standard for enterprise management. By using the method of industrial engineering to improve the existing problems of the production line, a 0-1 integer programming mathematical model of molding production line balance optimization of A company,a satisfactory solution.Optimization of the operating units assigned to workstations,each workstation is consumed by the total balance. Production efficiency and economic benefit of enterprise has been greatly improved, has high practical significance. Of course,this paper studies on the production line balancing problem of A company has some shortcomings, making the operation unit has not reached the standard time of the micro level,worthy of further perfected and improved.
