An optimum design selection approach for product customization development

Abstract

Consumer preferences and information on product choice behavior can be of significant value in the development processes of innovative products. In this paper, product customization evaluation and selection model is introduced to support imprecision inherent of qualitative inputs from customers and designers in the decision making process. Focusing on customer utility generation, an optimum design selection approach based on fuzzy set decision-making is proposed, where design attributes priority is identified from customer preferences using an analytical hierarchy process. A multi-attribute analysis diagram is developed to visualize the preference of each attribute from the expert's group decision. Conjoint analysis is used in the product customization to focus on customer utility generation in terms of multiple criteria. The use of the decision-making method is illustrated with a case example that highlights the utility of the proposed method.

A Decision-Making Model Proposal (Aav) for Selection of Amphibious Attack Vehicles for Landing Platform Dock (Lpd) by Integrated McDm Methods

“…The objective of AHP is to achieve a hierarchical system by branching decision criteria and alternatives. (Albayrak and Erensal, 2004;Liu et al, 2012) Step 2: Perform the pairwise comparisons. In this step, comparison matrices are found out, and pairwise comparisons are evaluating.…”

Application of Multi-Objective Optimization on the Basis of Ratio Analysis (MOORA) Method for Bank Branch Location Selection

“…A decision problem is structured as a hierarchy. With the AHP, the goal, decision criteria and alternatives are arranged in a hierarchical structure similar to a family tree (Albayrak and Erensal, 2004;Liu et al, 2012). Experience and judgement slightly favor one over another 5…”

A Pro-Environmental Method of Sample Size Determination to Predict the Quality Level of Products Considering Current Customers’ Expectations

“…This assessment can be done in a subjective manner by the entity applying the method (i.e., experts) [57,58]. However, in the context of determining the product quality level taking into account customers' expectations, the importance of the attributes should be determined based on customers' assessments [4][5][6]. To achieve this aim, survey research can be conducted [24,25].…”

“…Simultaneously, pro-environmental changes are taking place at the society level, which are mainly manifested by the use of sustainability rules. This coexistence of aspirations to achieve high quality and sustainable development appears to be a natural competitive action of any well-managed organization [4][5][6], which concerns the sustainable design of new products and improvement of the quality level of existing products [7][8][9][10][11]. This process not only results in higher satisfaction of customers and good economic results, but also, and most importantly, the effective implementation of sustainable development [12][13][14][15][16].…”
