ABSTRACT

Aim to solve all kinds of problem existing in the angle grinder assembly line of the enterprise, such as the unreasonable distribution of work procedures, serious work in progress (WIP) inventory, chaotic production line layout and low assembly line balancing. Value Stream Map (VSM) is used to describe the layout and process diagram of the assembly line and a future value flow chart is established to optimize the angle grinder assembly line in this paper. IE method is utilized to improve the layout of the assembly line and bottleneck location, and the assembly line balance problem in advanced industrial manufacturing is combined with the genetic algorithm (GA). The assembly line improved effectively shortens the product assembly cycle, reduces the inventory and material handling distance, and improves the production line balance.
