“…Finally, the AHP became a useful approach to solve complex decision problems that prioritizes the relative importance of a list of criteria (critical factors and sub-factors) through pairwise comparisons amongst the factors by relevant experts using a nine-point scale. However, due to the vagueness and uncertainty of judgements of the decision-makers, the fuzzy number logic was introduced in the pairwise comparison of the AHP to make up for this deficiency in the conventional AHP [60]. Buckley [40] incorporated fuzzy theory into the AHP, calling the resulting theory FAHP.…”

Integration of Balanced Scorecard (BSC), Strategy Map, and Fuzzy Analytic Hierarchy Process (FAHP) for a Sustainability Business Framework: A Case Study of a Spanish Software Factory in the Financial Sector

This paper presents a case study of how a Spanish financial software factory (FSF) has determined the weights of the indicators and objectives included in their strategy map with the aim of ensuring its business sustainability. A strategy map is a graphical representation of the cause-effect relationships between strategic objectives and indicators of a balanced scorecard (BSC). The detailed description of the strategy map development and deployment is not part of the aim of this work as it was described in a former paper. In this study, FAHP, a multicriteria decision-making (MCDM) method using the concepts of fuzzy set theory and hierarchical structure analysis, was used to calculate the weights. The analysis was carried out considering the points of view of different groups of stakeholders (shareholders, top management, middle managers, other employees, customers and some experts in the field of software factories) and the results are presented grouped by role to get a better understanding of the preferences of each kind of stakeholder. The conclusions of this study give a better insight of the corporative sustainability strategies of this kind of firms as well as the different vision of each stakeholder, what could be very valuable to the software factory managers for the decision-making and the strategic management of their organizations.

“…The weight of each machine tool error need be considered to reflect the error's importance and influence to the resultant fuzzy cost, and this is very important to ensure the validity of the optimization results. The weights coefficients of every error are confirmed according to the Analytic Hierarchy Process (AHP) methods shown in literature [25]. The detail flow is as follows.…”

Abstract:Customer-oriented design is very important for machine tool manufacturers to win competition in the market. Mechanical parts with complicated sculptured surface are widely utilized in mechanical systems such as automobiles, aircrafts and wind turbines, and they are often machined by five-axis machine tools with high precision requirements. However traditional machine tool design has not accounted for the varied machining errors in producing complex sculptured surface, which leads to inferior performance. To address this challenge, a novel machining error synthesis model is proposed in this paper for accuracy optimization in designing general five-axis machine tools used for making various sculptured surfaces. The new synthesis model bridges between surface machining profile error and the machine tool accuracy, and it is constructed by integrating a generic machine tool volumetric error model and two new surface machining error production models. The synthesis model is then applied as a constraint in machine tool accuracy design optimization. Also a tolerance-cost function is formulated to construct the objective function, and a meta-heuristic algorithm is developed to implement the optimization. All these modeling and optimization methods are validated by one case study.

“…Where decision making could be a complex task, such problems can be effectively undertaken with multiple attribute decision making (MADM) approach. This approach has provided excellent results in complex decision-making problems in engineering (Zeki Ayağ & Özdemir, 2006;Vats & Vaish, 2013;Zhang, 2004). MADM utilized a lot of methods in literature which includes TOPSIS (Technique for order preference by similarity to ideal solution) (Chen, 2000;Farsijani et al, 2015), VIKOR (VlseKriterijumska Optimisacija I Kompromisno Resenje) (Opricovic & Tzeng, 2004;Yadollahi Farsi et al, 2012), and AHP (Analytic hierarchy process) (Chang, 1996;Kahraman et al, 2003), SAW (simple additive weighting) (Chen & Klein, 1997), etc.…”

“…The Fuzzy AHP approach permits a more perfect depiction of the decision making process. Fuzzy AHP approach is outstanding MADM approach and has been applied to various problems ranging from supplier selection (Kahraman et al, 2003), machine tool selection(Zeki Ayağ & Özdemir, 2006;Durán & Aguilo, 2008),project selection (Huang et al, 2008),Information technology sector (Lee, Chen, & Chang, 2008), manufacturing systems (Weck et al, 1997),and many more (Kaviani et al, 2014;Varmazyar & Nouri, 2014). This study aims to prove the validation of the proposed Fuzzy AHP Approach for selection of critical alternatives for capacity waste on a real life system.…”

Capacity waste management is highly essential because under utilization of capacity is often referred to as a major reason for lower productivity among industries around the world. For better estimation of capacity and its utilization and then for its improved management; newer techniques are being devised in industrial sector. The current case of capacity waste problem has been taken up as a Six Sigma project, where we try to analyze critical factors responsible for the capacity waste. Decisions on critical factor selection in analysis phase of Six Sigma are always very crucial. The paper discusses an approach for selection of capacity waste factors at an automotive industry using fuzzy logic based AHP method. The fuzzy AHP is a well recognized tool to undertake the fuzziness of the data involved in choosing the preferences of the different decision variables engaged in the process of capacity waste factors selection. In this context, we have explored six crucial parameters for selection of capacity waste factors. Final ranking is calculated through priority vector thus obtained and it is seen that conveyor malfunction is found to be the key factor for capacity waste among all alternatives at the selected site.ed.
