The Requirements Development Model Based On The QFD And Application In Development Of The Q Type Elevator Car

With the development of the economy, the elevator has become the most widely applied i n approximately traffic tools. But the requirement of people is rapidly changing, the basic nee ds of the original is able to run up and down, until now to pay more attention to the function o f the interaction and comfortable decoration. User satisfaction with the car of GR company pr oduct is not high, compared with the industry benchmark enterprise competitive power is relat ively weak. Implement take the market as the center, to customer requirement for drive produ ct development mode has not been formed. This topic is to GR type high-speed elevator Q car product requirement and development as the research on object, the purpose is to solve more often project requirements on the basis of subjective definition, lack of according to the marke t and customers, and no system requirements development process and mode.For requirements engineering and related tools including QFD, KJ method, AHP method,KANO model have carried on the related research. Combination of requirements engineering with QFD tools such as requirements development model is established, and is systematic ap plication. Research on the preparation of the requirement development; get the influencing fac tors and the research object. From the existing products to obtain requirement, listen to custo mer voice: user satisfaction survey, arrange interviews, and the professional team survey. Hier archy of requirements is divided: application of KJ method for dispersing demand clustering a nalysis. Hierarchy of needs analysis: application stratification grading important judgment ma trixcalculation, to obtain the desired attention prioritization. Press Keno demand model to jud ge the properties, positioning analysis of customer requirements. Convert customer requireme nts into the design requirements, the requirement for quality planning: the development of me asures and programs, the difficulty of adding the adequacy and implementation. Carry out the comprehensive importance calculation, set the target value. Compared with competitors, histo rical data as an improvement point, so that the target value is driven by the customer requirem ent. To carry out the analysis of the relationship between demand and product function test: th e matrix relationship is calculated, and it has the ability of measuring, avoiding the developme nt of product cannot meet the requirements. To carry out the calculation of the matrix relations hip between needs and provide a reference for decision making. Finally, combine the scene an d the goal, formulate the plan oriented demand, and realize the definition of customer require ments.This topic combines requirements engineering and QFD application of requirements dev elopment model, and applied in the Q type car product development. For GR Company the requirement-oriented product development model is established, as well as in traditional industr y product development and get high quality requirements and planning provides a practical so lution can be drawn lessons from and processes.
