The System Analysis And Design Based On Build-to-Delivery Production Mode In GR Elevator

With severity of the homogeny competition, the customer request of quick respond is much high. More and more companies take shortening lead time as the competition strategy, and that decides the enterprise production mode .Lead Production can provide the less cost as well as the much high quality, and it can also provide the different style products to the customers to choose. But it can't customization. Mass Customization (MC) can make the customization come true and be close to the cost of Mass production, but it can't carry out the instant customerization (IC) and instant delivery. With the request developing, production mode turns to the IC from MC, whose request the time more and more rigor with the low cost. This is the demand of the market development.China has been becoming the most big elevator market, which attracts almost all the elevator companies. Big elevator enterprises share the 80% market by the scale economy, who adopt with MC. Minor enterprises share the 20% market by the economies of scope, which have the advantage of the quick delivery and the customerization. In the same time, there exists the tight relation between the elevator and the building project. The delay of the building project or the need of using of elevator will lead the high inventory in the elevator company. So there produces a new demand for the elevator enterprise to shorten lead time furthest when meets the individuation .The article analysis production system from the elevator market environment , product character, the order fulfill process, and supply chain., construes the reason resulting in the high inventory in the GR Elevator Company by reviewing the production mode and the analyzing of the build-to-order(BTO) in the car industry and the household- electrical- appliances industry , puts forward that the elevator enterprise should establish the production mode of build-to-delivery(BTD) to participate the Time Based Competition(TBC) and solve the problem of high inventory and low profit rate. Through establishing GR 3-dimension harmony model among the product architecture, process architecture and supply chain architecture of the production system, the article sets up the transition logical frame from build-to-forecast(BTF) to BTD by soft systems methodology(SSM), designs the system detailed from how the decision configuring, analysis how GR carries out the BPR in the order fulfilling process and achieve the pull logical extending to the customer. In the end the article confirm the cost advantage of BTD by calculating the minimize cost of elevator Car production with the Excel linear programming.The study have the application value for GR in keeping low cost, shortening lead time and carrying out the quick respond in the elevator homogeny competition ,and then upgrade the enterprise's core competence.
