工业工程生产线平衡毕业论文（Graduation thesis on balance of industrial engineering production line） Shandong University of Science and Technology bachelors degree thesis introduction 1 Introduction 1.1 research background water flow assembly line this production organization was born in 1914 in the United States Ford company, can greatly improve labor productivity. On the eve of the birth of the assembly line, in 1913 August, the Ford assembly workshop, each chassis operated by a worker, completed 12.5 hours per assembly. A few months later, when the assembly line test flow is successful, the completion of an automobile chassis for 93 minutes, labor productivity has increased by more than 8 times. The flow assembly line created a huge car market, and also made the Ford Motor Co more productive than general motors. It can be said that Ford invented the assembly line, opened the prelude to modern production. The ALB problem is the balance of the production line with the advent of the production line, at the same time, since 1913, HenryFord invented the first assembly line, until 1950s, precisely before 1954, balancing assembly line only Trail-and-Error method in the attempt. Research published no problem ALB publicly, officially put forward and solve this problem is the Bryton Braces COMSOALComputer Method of of American Sequencing Ope rationfor Assembly Lines, the system records the simple way of random assignment of distribution operations element, enterprises in practice this method is universal. Another famous heuristic algorithm, RPWThe RankedPosition Weight Heuristic, sorts the assigned jobs elements according to certain rules and assigns them to each workstation. As we all know, there are mainly two ways to improve the efficiency of the system: first, to increase input to improve. Most of the enterprises have a tendency to go this way, generally the use of advanced management methods (such as ERP) to improve the management or purchase a large amount of equipment to improve t
