4. Introduction • 品質機能展開(QFD)是一個提升顧客滿意度的有效的產品開發工具。 • 品質機能展開(Quality Function Deployment，QFD)是聆聽顧客的聲音，將客戶對產品的需求進行多層次的演繹分析，轉變為產品設計要求、零組件的特性、製程設計要求、生產要求的品質工程管理技術。

5. The components of House of Quality 獲得顧客需求(CNs)，並分析這些顧客需求的相對重要性。

6. The components of House of Quality 對於顧客需求，發展出重要的產品技術需求(PTRs)。

7. The components of House of Quality 決定顧客需求與產品技術需求的相關強度，又稱為關係矩陣。

8. The components of House of Quality 決定產品技術需求之間的相關強度，又稱為相關矩陣。

9. The components of House of Quality 計算設計需求的技術重要評比，及評估它們的技術困難性和成本。

10. The components of House of Quality QFD 規劃過程中，有許多主觀評估，使得資訊不精確。

11. House of Quality Deployment • Deploying the voice of customers from design through production.

17. AHP可以說是ANP的特例。 • ANP 最大的特色在於釐清「因素之間互相依賴與錯綜複雜的回饋關係」，並定義出因素的真正重要性。 Analytic Network Process in QFD • The ANP procedure generalizes the AHP as a widely used multi criteria decision-making tool by replacing hierarchies with network. (Saaty, 1996) • The ANP can be used as an effective tool in those cases where the interactions among the elements of a system form a network structure. (Saaty, 1996)

18. Analytic Network Process in QFD • The hierarchical representation of the HOQ model.

19. Analytic Network Process in QFD • The network representation of the HOQ model.

20. ANP structure in QFD model • The network representation in QFD model is based on the structure of a hierarchy with inner dependencies within components and no feedback. • The network representation of the HoQ model.

21. ANP structure in QFD model • The supermatrix representation of the QFD model. • w1 is a vector on the CNs that represents the impact of the goal, namely manufacturing a product that satisfies the customer. • W2 is a matrix that denotes the impact of the CNs on each of the PTRs. • W3 and W4 are the matrices that represent the inner dependence of the CNs and the inner dependence of the PTRs.

22. Analytic Network Process in QFD • Integrating ANP into modified QFD W4 Using ANP W3 Using ANP W1 W2 W

25. ANP in QFD for a hypothetical writing instrument(1) • The CNs and DRs of a hypothetical writing instrument are schematized in Figure. The whole HOQ can be seen as a network system.

26. ANP in QFD Step 2 W1

27. ANP in QFD for a hypothetical writing instrument(2) • Assuming that there is no dependence among the CNs, the pairwise comparison of the CNs by using linguistic variables is made with respect to the goal. 0.99

28. ANP in QFD Step 3 W2

29. ANP in QFD for a hypothetical writing instrument(3) • By assuming again that there is no dependence among the DRs, they are compared with respect to each CN yielding the column eigenvectors regarding each CN. ALI VSLI SLI WLI EI WMI SMI VSMIAMI

30. ANP in QFD Step 4 W3 Using ANP

31. ANP in QFD for a hypothetical writing instrument(4) • The inner dependence among the CNs is determined through analyzing the impact of each CN on other CNs by using pairwise comparisons.

32. ANP in QFD for a hypothetical writing instrument(4) • The inner dependence among the CNs is determined through analyzing the impact of each CN on other CNs by using pairwise comparisons.

33. ANP in QFD Step 5 W4 Using ANP

34. ANP in QFD for a hypothetical writing instrument(5) • Deal with the dependence among the DRs. As previously accomplished for CNs, the inner dependencies are determined and therequired pairwise linguistic comparisons are performed.

35. ANP in QFD for a hypothetical writing instrument(5) • We deal with the dependence among the DRs. As previously accomplished for CNs, the inner dependencies are determined and therequired pairwise linguistic comparisons are performed.

37. ANP in QFD for a hypothetical writing instrument(6) • We obtain the interdependent priorities of the CNs as 0.99

39. ANP in QFD for a hypothetical writing instrument(7) • The interdependent priorities of the DRs are calculated as follows: 1.01

40. ANP in QFD for a hypothetical writing instrument(8) • Finally, the overall priorities of the DRs, wANP, reflecting the interrelationships within the HOQ are calculated by as follows:

41. ANP in QFD for a hypothetical writing instrument(9) • The HOQ obtained using all the data from the previous steps is depicted in Fig.

42. Formulate and Solve the ZOGP • The general form of the ZOGP model employed in the decision framework is as follows ANP Cost Preference rating of PTR

43. Formulate and Solve the ZOGP ANP Cost Extendibility Manufacturability

44. Conclusion • In the HOQ, there exists symmetric or asymmetric relationships between CNs and DRs and also among them. • Determining the relative importance of DRs is a fundamental problem in HOQ applications for product planning. • Uses the analytic network process (ANP), the general form of the analytic hierarchy process (AHP), to prioritize DRs by taking into account the degree of the interdependence between the CNs and DRs and the inner dependence among them.

45. Questions • Is the ANP network right ? • pairwise comparison. • Is the ANP better than AHP？ • Fuzzy set.
