A Method for simultaneously Handling
نویسندگان
چکیده
In this paper, we develop a model for uncertain default reasoning. It has the following characteristics: 1) basic uncertainty is estimated in terms of an interval number, and so the ignorance about knowledge can be coped with; 2) it has some capability of handling commonsense knowledge in forms of default rules with uncertainty, in which Reiter's system is a special case; and 3) the propagation for uncertainties is built completely on fuzzy mathematics. Hence, this paper forms an alternative approach that allows us to handle ignorance, uncertainty and incompleteness simultaneously.

Software defects detection is one of the most important challenges of software development and it is the most prohibitive process in software development. The early detection of fault-prone modules helps software project managers to allocate the limited cost, time, and effort of developers for testing the defect-prone modules more intensively. In this paper, according to the importance of soft...
متن کاملA decision making model for outsourcing of manufacturing activities by ANP and DEMATEL under fuzzy environment
Decision making about outsourcing or insourcing of manufacturing activities is a type of multiple criteria decision making (MCDM) problem, which requires considering quantitative and qualitative factors as evaluation criteria simultaneously. Therefore, a suitable MCDM method can be useful in this area as it can consider the interactions among quantitative and qualitative criteria. The analytic...
متن کاملSolving a new mathematical model for cellular manufacturing system: A fuzzy goal programming approach
A fuzzy goal programming-based approach is used to solve a proposed multi-objective linear programming model and simultaneously handle two important problems in cellular manufacturing systems, viz. cell formation and layout design. Considerations of intra-cell layout, the intra-cell material handling can be calculated exactly. The advantages of the proposed model are considering machining cos...
متن کاملThe Combined Reproducing Kernel Method and Taylor Series for Handling Fractional Differential Equations
This paper presents the numerical solution for a class of fractional differential equations. The fractional derivatives are described in the Caputo cite{1} sense. We developed a reproducing kernel method (RKM) to solve fractional differential equations in reproducing kernel Hilbert space. This method cannot be used directly to solve these equations, so an equivalent transformation is made by u...
