This paper presents a genetic algorithm (GA) based fuzzy goal programming (FGP) solution method to multiobjective decision making (MODM) problems with fractional criteria. In the model formulation of the problem, first fractional objectives are transformed into fuzzy goals by defining the imprecise aspiration levels to each of them by employing the proposed GA. Then, the concept of membership functions...
This paper present a new method for multiple response optimization (MRO). Multiresponse problems comprise three stages: data gathering, model building and optimization. The most work in MRO don't consider the results of modeling stage while these outcomes can help in achieving the solution. In this paper, we incorporate the obtained results from stage of model building, i. e. the least significance...
This article presents a linear approximation approach to the fuzzy goal programming (FGP) formulation of solving multiobjective decision making (MODM) problems with chance constraints. In the proposed approach, first the chance constraints are converted into their deterministic equivalent in the decision making environment. Then, the individual best and worst solutions of each of the objectives are...
Weight flexibility is the main reason why the traditional DEA models can' t be directly used in ranking. The current paper proposes a multi-objective DEA model to derive common weights to weaken or eliminate the weight flexibility. In out proposed approach the obtained common weights can be accepted by at least half of all decision making units. The proposed technique is used in the university evaluation...
In this paper, based on the Lebesgue measure of level cutsets and the membership degree of an element in level cut-sets, we introduce the concept of level creditability of fuzzy numbers, present a necessary and sufficient condition of level creditability being equal to 1 for each ?? ?? [0,1], and then consider the basic properties (such as continuity, monotonicity etc.) of level creditability and...
Evacuation is an important issue that all occupants should be able to evacuate to safety from large public buildings under emergency. In this paper, present an individual decision-making model based on agent technology. For this model, a computer program is developed to simulate the flow phenomenon of crowd pedestrian. Three cases have been studied where arching, clogging of pedestrians at the exit...
The concept of decision making is an important issue that has been recognized in requirements prioritization because most projects are constrained by budget and time; therefore it is often difficult to implement all requirements that have been elicited for a system. For prioritization purposes, many approaches have been proposed so far to help the process but still it is not possible to get a real...
This paper is aimed at presenting a linear programming model based on fuzzy set theory. We use linguistic values to assess weights and ratings of supplier selection criteria. And then a hierarchy multiple model based on fuzzy set theory is expressed. According to the fuzzy positive-ideal solution and fuzzy negative-ideal solution, we create the linear programming model which is suited for multi- supplier...
Most software engineering methods presume that requirements are explicitly and completely stated; however, experience shows that requirements are rarely complete and usually contain implicit requirements. The failure or success of a software system depends on the quality of the requirements. The quality of the requirements is influenced by the techniques employed during requirements elicitation. Requirements...
In the context of product customization, customers and manufacturers are often unable to accurately articulate need and solution information. This paper takes product configuration as a process of collaborative design and introduces negotiation as a new method to support interactive decision making. A general framework for negotiation-based configuration is developed based on negotiation analysis...
This paper studies the dynamic decision-making problem in the intuitionistic fuzzy environment. For the decision matrix composed by intuitionistic fuzzy numbers, the intuitionistic fuzzy priority rating model is established to determine the membership relation of each alternative to the excellent alternative set, which is also described by intuitionistic fuzzy number. Furthermore, based on the score...
This paper develops a supplier evaluation approach based on the analytic network process (ANP) and fuzzy synthetic evaluation under a fuzzy environment. Instead of the classical eigenvector prioritization method, employed in the prioritization stage of the ANP, a fuzzy preference programming method is applied, which obtains crisp priorities from inconsistent interval and fuzzy judgments. The resulting...
Although the benefits are well-known and undisputed, sharing architectural knowledge is not something architects automatically do. In an attempt to better understand what architects really do and what kind of support they need for sharing knowledge, we have conducted large-scale survey research. The results of our study indicate that architects can be characterized as rather lonesome decision makers...
A decision by the Department of Defense (DoD) to recommend the use of the Resource Adapter Information (RAI) Framework element in Automatic Test Systems (ATS) acquisition will involve a combination of factors, decisions, and program requirements. Significant work in the last few years has produced a definition and helped to clarify the requirement for RAI. The IEEE Std. 1641 Standard for Signal and...
The concept of ordered weighted averaging (OWA) operator weights arises in uncertain decision making problems, however some weights may have a specific relationship with other. This information about the weights can be obtained from decision makers (DMs). This paper intends to introduce a theory of weight restrictions into the existing OWA operator weight models. Based on the DMs' value judgment the...
According to the current application and maintenance situation of numerical control equipment (NCE), a novel remote fault diagnosis expert system is designed to prevent fault occurrence and quicken the recovering process by online real-time monitoring the working state of NCEs. The article addresses the overall framework and relevant application technology of fault diagnosis system (FDS) and emphasizes...
In professional tennis training matches, the coach needs to be able to view play from the most appropriate angle in order to monitor players activities. In this paper, we present a system which can adapt the operation of a series of cameras in order to maintain optimal system performance based on a set of wireless sensors. This setup is used as a testbed for an agent based intelligent middleware that...
Flow shop production lines have been practiced for many years in manufacturing systems. Makespan is the total completion time of all the activities and is known as one of the most criteria in manufacturing systems. Minimizing this criteria causes more efficiently use of the resources specially machinery and manpower. By assigning some budget to some of the operations the operation time of these activities...
Proper partner selection is the key factor in successful logistic outsourcing. The paper firstly reviews the literature in partner selection at home and abroad. Then, combining with the characteristics of logistic cooperation partner, puts forward a multi-stage partner selection mode integration with data envelopment analysis (DEA) and 0-1 target programming. Based on the above-mentioned research...
The task to design a reliable engine protection system with highest reliability while considering system cost, weight and volume constraints under uncertain environments is very challenging. In this study, a fuzzy-based data envelopment analysis (DEA) reliability modeling approach is developed for designing reliable aircraft engine protection systems.
