Quality improvement pilot program selection based on dynamic hybrid MCDM approach

Abstract

Purpose Driven by motivation of quality enhancement and brand reputation promotion, automotive industries try to improve product quality and customer satisfaction by performing quality pilot programs continuously. The purpose of this paper is to develop a dynamic model to select the improvement quality pilot program from competitive candidates based on dynamic customers’ feedback. Design/methodology/approach An extended dynamic multi-criteria decision-making method is developed by embedding dynamic triangular fuzzy weighting average operators into fuzzy VlseKriterijumska Optimizacija I Kompromisno Resenje (VIKOR) method, and the novel evaluation indicator “ζ” is introduced to reflect prioritization performance. Findings The two evaluation indicators (Q and “ζ” ) assist quality managers to identify the best program with respect to multiple conflicting criteria and the best choice based on these two indexes shows high conformity. Besides, ranking sequences obtained by “ζ” can avoid the dilemma that there are several candidates with top priority calculated by comprehensive group utility value Q. Practical implications The dynamic MCDM method has been applied into the quality improvement procedure in Chinese domestic auto factories and contributes to highly efficient promotion. Originality/value Few dynamic models on pilot program selection for quality improvement based on dynamic customers’ feedback, this study deals with the dynamic promotion by an extended fuzzy VIKOR method and presents a case application.

A Fuzzy Decision Support System for Sustainable Construction Project Selection: An Integrated FPP-Fis Model

“…Prascevic & Z. Prascevic, 2017). Therefore, many fuzzy MCDM methods (Mohammed et al, 2019a(Mohammed et al, , 2019bZhou et al, 2018aZhou et al, , 2018b) such as FANP, FTOPSIS, FAHP, FDEA, etc., have been applied for decision making under uncertainty.…”

Service Quality Evaluation of Terminal Express Delivery Based on an Integrated SERVQUAL-AHP-TOPSIS Approach

“…Negative online reviews from social media are extracted to evaluate museums' service failure, and twelve service quality indicators are identified and highlighted [39]. To assist discovering the performance gaps of their products, according to the feedbacks of after-sales service systems, the quality improvement priority index was proposed and developed to identify pilot objective for further improvement [40,41].…”

Identifying the Strategic Priorities of the Technical Factors for the Sustainable Low Carbon Industry Based on Macroeconomic Conditions

“…In these studies, the MCDM approach was used only to rank the alternatives. However, no method was taken into consideration in the calculation of criterion weights (F. Zhou et al, 2018). In this process, criterion weights were either accepted as equal to each other or determined subjectively by the researchers (Debnath et al, 2017).…”
