| Popis: | The main problem of this paper is to improve product planning through the distinction between engineering specifications of the product, and the nomination of the basic engineering specifications that are depend in the development process, according to the opinions of different designers and customers, that take into account more than one goal to achieve the principle of competition for the product. To achieve this goal, a new hybrid methodology has been built. This new methodology utilized Quality Function Deployment (QFD) with fuzzy logic for improving product planning. The methodology was conducted in six models that include four different of House of Quality (HOQ); two of them are in traditional state, and the other in fuzzy state. These models are current crisp QFD model, virtual crisp QFD model, initial fuzzy QFD model, final fuzzy QFD model, optimum fuzzy QFD model and optimum crisp QFD model. Application results show new values and ranking for the new engineering specifications of the desired product to be developed, and it was possible to use the values of these specifications by the designer in its crisp format rather than the fuzzy. Thus were able to find out the critical and important specifications for improving product planning which should be considered in product development process. |
