Abstract

In long term, Mass production has the top status in manufacture industry because of its scale effect. But in recent decades, the market environment has big changed. Manufacture industry itself is on the process of renovation. From stock production to lean production, from mass production to mass customization and then to customization, all of these reflect the changes brought by demand differentiation, diversity production and business mode. Mass customization and even make to order production with small batches, multi-type becomes more and more new developing trend in manufacture industry. But, because of the strong uncertain demands and lower production repetition, the plan and control of production operation process of such make to order production with multi-type and small batches is very complicated.Along with the process of becoming leading manufacturing country in the word, the Chinese manufacture industry is facing develop opportunity never seen before, and at the same time, also feel the pressure of survive and develop in the globe competition environment. Under the make to order production mode, the enterprises face the demand environment with more change and individuation, and the customer has the higher requirement to the enterprise’s ability to meet customer requirement. So, whether the enterprise can realize good operation efficiency, rapid-response customer requirement, not only related to the quantity of enterprise’s profit, but more related to its survive.Railway vehicle and its related components has the character of multi type and specification, less quantity demand of single type and less application of the same type and specification product in different projects. It is a typical make to order industry. Specially, the problems of multi-type, small batch, more unexpected changing and high frequency production line changing exist more in the components and part manufacture enterprises in this industry. In this production mode, the production processes in enterprises are dynamic and changeful. And this dynamic and changeful does not only exist in the enterprise itself, but also expanded to whole supplier chain including suppliers. The on time delivery of purchased and outsourced parts becomes one of the most key factors for whether the enterprise can fulfill the contract delivery date on time. The resource and production capability of supplier becomes part of enterprise’s planning system. So, the production planning method based on mass production can not meet the requirement of production management for make to order mode. In railway vehicle industry, how to setup effective production planning and control system to rapid response the requirement of customer and unexpected change is the concern aspect by enterprises who want to resolve the delivery delay problem which commonly exists in the industry.Through the analysis of the current operation, planning mode and existed problems in a assembly company who provides key component to the railway vehicles, and consider the characteristic of the company, its project and product, this paper discusses the production planning, control method and its implementation under ATO (Assembly to order) mode. By set up a set of long, medium and short term planning system which has forecast, dynamic updating, accuracy and flexible character and its related plan control and information transfer mechanism, to improve the production management of the company to reach the target of capacity balance, dynamic response, accuracy controlling planning progress and rapid response to change. Based on that, this paper uses the actual project data of this company to simulate implementing the plan and control system for verifying its effectiveness. The research of this paper has certain reference meaning to management practice of this company and also to the plan and control work of similar enterprises.
