This paper proposes a hybrid framework combining AHP (Analytical Hierarchy Process), QFD (Quality Function Deployment), Entropy and TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) method to incorporate customer preference and perception into the process of product development. QFD is a useful analysing tool in product design and development to identify these latent customer requirements. In this paper, first by using AHP several customer requirements are identified and prioritised. Secondly, by using fishbone diagram the relationship between technical attributes and customer requirements are listed and these relationships are put in a house of quality. Entropy method is used to calculate sales point. Afterward, TOPSIS method is used to find the best and worst alternative solution. The proposed method is used for evaluating the performance of the bathtub. Then the rankings of the four renowned bathtub companies are determined according to their results.
Cutting fluids are important elements of manufacturing industries and are used in large quantities. But its use poses a serious health issue to the surrounding people working in its atmosphere. Hence, the disposal should be only after neutralization thereby protecting worker and aquatic life. This leads to select an optimal alternative that is not only environmentally friendly but also safe for human beings and aquatic life. Further, it should also perform at par with the mineral oil-based cutting fluid. In the present research, a framework has been proposed to assist the decision-makers in the selection and evaluation of lubricant by the Analytical hierarchical process (AHP) and VIKOR method. In the proposed research three cutting fluids i.e. Neem oil with 5% emulsifier, Neem oil with 10% emulsifier, and a conventional mineral oil-based cutting fluid have been considered as alternatives. These have been evaluated on the basis of different significant parameters like the temperature at the tooltip, surface roughness, and tool wear. The basic aim of this paper is to present the logical selection process of a cutting fluid as well as to show that ranking or choice of cutting fluid may also change if the priority of the parameter is changed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
