An Aggregated Supplier Selection Method Based on QFD and TOPSIS (Case Study: A Financial Institution)

With daily development of information technology supply chain of service-based organizations like financial institutions and the increased value of outsourced activities, also the importance of customer satisfaction, outsourced affairs must have done by the suppliers who have the ability of accomplishing the organizational demands. To mitigate the risk of invalid supplier selections, verification and selection of the suppliers should be performed with an optimized and systematic solution. In order to help the selection of suppliers in the IT department of financial organizations, a different model by using a hybrid QFD-TOPSIS solution in MCDM methods is suggested, in this study. First goal of the provided model is finding the most related criteria and the second one is offering an optimized solution to the supplier selection problem. To begin the QFD part in the mentioned method, two categories of criteria are needed. Then, after the formation of the House of Quality, in a real case study that was performed in a private bank in Iran, the suppliers are ranked by using the proposed method. The greatest efficiencies of this method are not only finding the best supplier by measuring the nearest distance to the ideal and the farthest one to the negative-ideal solution but also closing the opinions of employers to the technical requirements (sub-criteria) of information technology supplier qualifications. Finally, a model reliability part is designed to indicate the validation of the proposed method and a sensitivity analysis is implemented to find the most sensitive sub-criteria. That is the results of ranking alter if sensitive sub-criteria change .

Formulation of a Manufacturing Strategy Using the House of Quality

This paper describes a framework to formulate a manufacturing strategy based on the House of Quality (HOQ). This method consists of two main phases. The phase I relates what the market wants (the WHATs) with the manufacturing decision categories (the HOWs). The WHATs are expressed as the manufacturing objectives (i.e. cost, quality, delivery, flexibility and innovation) and the HOWs are expressed as the strategic manufacturing decisions areas (such as, facilities, capacity, process technology, new product design and control systems). A matrix is built, where the rows are the WHATs and the columns are the HOWs. The entries of the matrix are the relationships between both types of concepts. The “roof” of the house is the relationships between the manufacturing decisions (the HOWS). The analysis of this House allows managers to generate strategic action plans in order to fill the gap between what the market wants and what manufacturing is achieving. The phase II builds another house, where the WHATs are the manufacturing decision areas and the HOWS are strategic manufacturing plans. In this phase the strategic action plans are ranked. The application of the proposed method in a company that manufactures industrial tanks is shown.

A new hybrid supplier selection model

Selecting the right supplier is one of the most challenging tasks for organisations as it essentially reduces purchasing cost and improves corporate competitiveness. This study aims at developing a hybrid model in supplier selection for a non-homogeneous group decision-making process to select a supplier that best satisfies the purchaser. The analytical hierarchy process (AHP), house of quality (HOQ), and linguistic ordered weighted averaging (LOWA) operator are applied in the proposed model. This model is illustrated with a real world example by applying it to a mechanical manufacturing company in Vietnam. It is found that supplier selection does not only depend on a low price offer, but also on supplier's quality, technological capability, capability of on-time delivery, flexibility and good relationship. This study makes new methodological and practical contributions to supplier selection research and applications through development of a hybrid model for non-homogeneous group decision making in supplier selection, and for the first time this study applies the LOWA operator in aggregating linguistic terms of non-homogeneous group decision making in a supplier selection process.

L.A.R.G. supplier selection based on integrating house of quality, Taguchi loss function and M.O.P.A.

Nowadays, companies are able to obtain the key to success in global competition by choosing the right suppliers who are more align with their strategies. It is clear that applying appropriate attitudes and criteria have a great importance in choosing suppliers in the process of decision-making by chain managers and especially purchasing managers. In this study tried to apply Lean, Agile, Resilient and Green (L.A.R.G.) approach in a model designed to select the consistence supplier. Accordingly, at first, while reviewing and exploiting the literature, the most main logistics needs of the company concerned in the light of the objectives that followed on the fields of the LARG attitudes, are refined and selected, then their degree of significance is determined through Multi-Objective Performance Analysis (M.O.P.A.). The house of quality (H.O.Q.) matrix is applied to determine the importance degree of the technical characteristics of the suppliers and Taguchi loss function is applied to determine the degree of their performance deviation from the target value in each one of the technical characteristics (ultimate judgment about their competency). The considered suppliers are ranked based on the results of the loss function analysis. A sensitivity analysis was conducted to analyse the impact of different conditions on suppliers’ ranking and validation of the ranking results were Satisfied by applying the T.O.P.S.I.S. method.

An Innovative Model to Choose E-Commerce Suppliers

Supplier selection for aquatic products E-commerce has aroused widespread concern due to the characteristics of fresh products and the popularity of the network. This paper proposes a novel fuzzy group decision method, which not only integrates quality function deployment (QFD) and improved technique for order preference by similarity to the ideal solution (TOPSIS) but also combines the qualitative analysis and quantitative analysis. Moreover, this method contains two stages, in the first stage, QFD is applied to determine the weights of customer requirements (CRs) and company strategies (CSs) by analyzing the relationship between CRs and CSs, the subjective importance weights of criteria can be derived, in addition, the house of quality (HOQ) is used to characterize the above process. To address the uncertainty in the selection process, intuitionistic fuzzy numbers (IFNs) are provided to describe the imprecise information, which take membership degree, non-membership degree and hesitation degree into consideration; in the second stage, a novel ranking method is proposed based on the improved TOPSIS, the objective importance weights of criteria are obtained, then the integrated importance criteria weights are calculated and a new ranking index is provided to rank the suppliers. What’s more, a case study illustrates the effectiveness and applicability of the proposed method. Finally, comparative analysis and sensitivity analysis are carried to demonstrate the robustness and effectiveness of the proposed method. The result shows that the proposed TOPSIS-based method can help companies monitor supplier performance and provide customers with quality products and services.

Formulation of an Agile Office Product: An Application of Axiomatic Design in Engineering

Axiomatic Design was applied in an undergraduate student-led project which culminated in the creation of an agile ergonomic monitor stand, a solution designed to optimise the productivity and working conditions of the office environment. The customer domain was determined using a Mendelow’s Stakeholder Analysis followed by contextual inquiries and lead user interviews. These customer needs were organised into different levels via Maslow’s Hierarchy and redefined in terms of functional requirements. The functional requirements were decomposed and classified using the Kano Customer Satisfaction and Long Tail Models, and ultimately organised into a functional requirement tree. Design constraints were considered and listed, and the customer and functional domains were compared using a House of Quality. This allowed potential design paths to be devised with respect to the chosen functional requirements. The path involving the smart ergonomic stand was chosen from a number of potential products assessed against the functional requirements by listing the potential design parameters in a morphologicalmatrix. Concepts were designed by creating combinations of these design parameters, with their suitability being judged using the Independence Axiom. The physical form of the solution was inspired using biological sources. The final details of the design were chosen using the Information Axiom to determine their suitability in practical implementation allowing the final concept to be produced in a 3D CAD model.

One approach to evaluate the influence of engineering characteristics in QFD method

Evaluation of engineering characteristics (ECs) according to customer requirements (CRs) is the most decisive step of the house of quality in quality function deployment (QFD) method. In most cases, high degrees of correlation between ECs exist and should be modelled. The paper develops a specific measure ('influence gap') and novel underlying procedure (smallest gap technique) for ECs evaluation aiming to capture all interdependencies. The influence gap enables to characterise each EC according to its distance from ideal-maximum influence on all requirements. The relationships between CRs and ECs and their inter-relationships are obtained using interval-valued fuzzy DEMATEL method. From the practical point of view, the most important information for decision maker(s) generated by the model is the clear insight about the contribution of each EC when launching a new product/service. Practicability and usability of the proposed methodology is illustrated over a specific transportation service. [Received: 6 January 2018; Accepted: 2 December 2018]

A novel collaborative manufacturing model requiring both geometric and physical evaluations of spiral bevel gears by design for six sigma

Collaborative manufacturing requiring both geometric and physical evaluations has been an increasingly important trend in the industrial applications of spiral bevel gears. It is an innovative attempt that design for six sigma (DFSS) is introduced to establish a model of above collaborative manufacturing system. In the DFSS-based modeling, in addition to establishing the basic framework, the related data-driven decision and optimization are proposed, respectively. The house of quality (HOQ) is firstly established to convert the voice of customer (VOC) into the critical to qualities (CTQs) and determine the geometric and physical evaluations. Then, the conventional machine setting modification is extended to the multi-objective optimization (MOO) modification considering both geometric and physical evaluations. The whole system is divided into the three data-driven sub-problems for their respective decision and optimization. First, the accurate measurement and compensation is used to operate the noise factors in the actual manufacturing. Second, a prescribed ease-off topography is identified as the target flank by MOO of the physical evaluations. An improved high-order modification of the optimal machine setting is performed to optimize the geometric performance. A case of study on measurement-modification-machining (3 M) collaborative manufacturing system is provided to verify the proposed model.
