Research On Product Function Balance Based On Customer Requirement

By balance the mutual influence in function and cost of products, Value Engineering has its unique advantage over other theories to be used in R&D. Nevertheless, Present designers pay more attention at cost analysis according to certain product structure and how to reduce the cost of object when they use VE theory and technique.Furthermore, present functional analysis techniques are mainly on the qualitative but not the quantitative.Because of these deficiencies of present VE theory, dissertation put forward the product function balance base on customer requirement.On the basis of customer requirement, researches are detailed in function system planning and function level positioning. In the first place,the function system planning which aims at core product emphasizes customer requirements analysis, function hierarchy analysis and general function planning, considering these insufficiency at theory. Finally, the method is discussed in process of the function system planning of an multifunctional hairdressing machine.This dissertation has also conducted some research in deficiencies of present VE theory by excepting efficacious foreign method with function level positioning method according to tangible product in modern total product conception. On the basis of QFD technique and IQFD principle, a function level-positioning framework is established according to AHP. In terms of this framework, all elements of planning matrix can be acquired. After quantitative analysis of functional attribute and customer requirement, a linear planning model whose decision-making variables are function attributes is constructed. By this model, we can conduct level positioning of function attributes. In conclusion, the above-mentioned model is applied in the function positioning of the newly ATM which empoldered by company auchor exercitation in.Researches of this dissertation are the perfection and penetration of present value engineering theory, which will have certain theoretical and practical significance to enlarge application of VE and improve early R&D quality of product.
