In this paper, linear systems with a crisp real coefficient matrix and with a vector of fuzzy triangular numbers on the right-hand side are studied. A new method, which is based on the geometric representations of linear transformations, is proposed to find solutions. The method uses the fact that a vector of fuzzy triangular numbers forms a rectangular… (More)

In this paper, systems of linear differential equations with crisp real coefficients and with initial condition described by a vector of fuzzy numbers are studied. A new method based on geometric representations of linear transformations is proposed to find a solution. The most important difference between this method and methods offered in other papers is… (More)

We consider a fuzzy linear system with crisp coefficient matrix and with an arbitrary fuzzy number in parametric form on the right-hand side. It is known that the well-known existence and uniqueness theorem of a strong fuzzy solution is equivalent to the following: The coefficient matrix is the product of a permutation matrix and a diagonal matrix. This… (More)

In this paper, a linear system of equations with crisp coefficients and fuzzy right-hand sides is investigated. All possible cases pertaining to the number of variables, n, and the number of equations, m, are dealt with. A solution is sought not as a fuzzy number vector, as usual, but as a fuzzy set of vectors. Each vector in the solution set solves the… (More)

In this study, we consider the aircraft landing scheduling problem (ALS). It is well-known NP-hard problem. This is an indicator that the optimal solution cannot be found at real time. We recommend a greedy algorithm for the solution of problem in this paper. For simplicity, this algorithm that is told for static ALS problem may also be generalized for… (More)

Image segmentation is a process of partitioning the images into meaningful regions that are ready to analyze. Segmentation of rock thin section images is not trivial task due to the unpredictable structures and features of minerals. In this paper, we propose Fuzzy Rule-Based Image Segmentation technique to segment rock thin section images. Proposed… (More)

In this paper, we investigate linear partial differential equations with fuzzy source function, and with fuzzy initial and boundary conditions. Usually, researchers consider solutions of fuzzy differential equations in the form of fuzzy-valued functions. On the contrary, in this study, we are looking for a solution in the form of fuzzy set (bunch) of real… (More)
