Research On The Process Improvement Of GR Lift Demand Pull Touch

Elevator belongs to the special equipment manufacturing industry, the country has strict laws and manufacturing specifications, and the elevator is customized products, according to customer demand for design, manufacturing, usually use pull mode for process specifications and production. This thesis takes the customer as the center of demand pull mode as the foundation, changing the elevator industry is only concerned about the express needs, the customer express and potential needs in conjunction with identification and management, the use of the value flow chart and other lean production methods, improve the production process, reduce or eliminate waste, take the road of lean production, in the elevator industry has reference significance.First of all, the research objectives, significance, research and description of the supply chain and its operation mode, value flow and other tools are described.The use of the value flow chart, and the status quo of the current situation, the main demand is not identified management, the key is not clear, the information flow, waiting time and the presence of non value-added links, etc., the use of process analysis method to determine the status quo, the main reason is not to identify and manage the customer demand, the key process is more than a special department management, the use of green channel occupy resources, each link inventory follow-up is not timely, information transfer is not clear and so on.Again, through the process analysis method, 5W method on demand are identified, finds out the key factors of demand management, and analyzes the management methods; also of key process one by one design combing, identify the key process, and the specification of information flow, again using the one-piece flow of thoughts, borrow production Kanban management method, to pull mode improves the design, through the value flow graph drawing the value stream chart the future.Finally, the use of comparative analysis method for the application of the situation and the effect of the description, to improve the delivery on time rate and reduce the number of the box head, while reducing the manufacturing waiting time, reduce the ratio of advance manufacturing, reduce the waste of resources.
