Lean Improvement of Product P Assembly Line based on Value Stream Map

Abstract

Based on the product P assembly line transformation project of a company, the main problems of the original production line are analyzed with the method of Value Stream Map. Lean improvement measures which is used in the design of new production line are put forward in the aspects of overall layout, process arrangement, production mode, material buffer, auxiliary equipment and personnel allocation to reduce some non-value added activities and wasteful behaviors. By the Value Stream Map of the improved lean production line, the evaluation indexes can be improved significantly. After the new production line is completed and put into production, the workshop stock is reduced, the production efficiency is improved, and the production cost is reduced.
