Our study examines the group decision-making process and proposes a multi-criteria framework for e-commerce solution investment in information technology (IT) portfolios. First, the evaluation criteria that fit in the IT evaluation context are constructed. Second, the Fuzzy Analytic Hierarchy Process (FAHP) is employed to determine the weights of decision criteria and the benefit score to the c...

Procurement planning with discrete time varying demand is an important problem in Enterprise Resource Planning (ERP). It can be described using the non-analytic mathematical programming model proposed in this paper. To solve the model we propose to use a fuzzy decision embedded genetic algorithm. The algorithm adopts an order strategy selection to simplify the original real optimization problem...

The following study focuses on the evaluation of a multi criteria decision problem by use of fuzzy logic. We will demonstrate the methodological considerations concerning group decision and fuzziness on the basis of a specific problem: the search for energy alternatives and a proper evaluation of these alternatives (in comparison to existing ones). This issue will be of increasing importance wi...

Healthy assessment weights of using of modern electronic equipment is too subjective problem, it is proposed in this paper that is based on fuzzy analytic hierarchy process and the method based on the theory of the D-S evidence. In solid state transmitter, for example, by analysis of working principle, from the perspective of healthy status evaluation, it will be associated with healthy status ...

The complexity of dynamic system, especially when only qualitative knowledge about the process is available, makes it generally difficult to elaborate an analytic model which is sufficiently precise enough for the control. Thus, it is interesting to use, for this kind of systems, non conventional control techniques, such as fuzzy logic, in order to achieve high performances and robustness [8, 1...

This paper proposes a new fuzzy adaptive exponential synchronization controller for uncertain time-delayed chaotic systems based on Takagi-Sugeno T-S fuzzy model. This synchronization controller is designed based on Lyapunov-Krasovskii stability theory, linear matrix inequality LMI , and Jesen’s inequality. An analytic expression of the controller with its adaptive laws of parameters is shown. ...

The high complexity of socio-economic environments often makes it difficult for a single decision maker (DM) to consider all important aspects of decision problems. Therefore, a group decision making (GDM) process is often preferred by organizations. Moreover, during the decision process, DMs may have difficulties in the prioritization of alternatives. Linguistic interval fuzzy preference relat...

Understanding the importance of the marketing competitiveness of the small and medium enterprises (SMEs) as the premise, analytic hierarchy process is used and the competitiveness of SMEs in the evaluation of the marketing model is put forward in the paper. The design of index system and evaluation model of steps are discussed, it is found that the fuzzy comprehensive evaluation method is an ef...

After 1 July 2006, a major challenge that the manufacturing industry has to confront now is the effect of the lead-free equipment system selection process on companies’ capital expenditure decision. With capital investment, the criteria may be financial (e.g. expected cash flows) and non-financial (e.g. product quality). We use a systems approach with the fuzzy analytic hierarchy process (FAHP)...

A subjective evaluation of services and agents play a fundamental role in open systems. The vague nature of the personal criteria used in subjective evaluations justify the use of fuzzy sets. This distributed approach requires cooperation (information sharing) between agents with similar criteria to improve decision making process. So similarity between criteria is used to decide whether cooper...
