Transport problems is very important in operational research. The transport problem has been solved several ways: north west corner, minimum cell cost and Vogel’s approximation method. In this study, I discussed a new method to find an optimal solution of transportation simple step. All methods were applied paper evaluate the results compare between them with respect Also, researcher example on...

The paper proposes a new approach to the multi-criteria fractional transportation problem with the same bottleneck denominators, additionally criterion for is also time constraint, i.e. the type bottleneck. We propose to study the case when the bottleneck criterion is not deterministic, but of fuzzy type. In this paper I propose an iterative algorithm for solving the model. It generates the cro...

The purpose of the study is to examine how students manifest social presence in IT-supported teaching methods. Specifically, the research examined how students’ psychological type, as measured by the Myers-Briggs Type Indicator, affects their perception of social presence in a specific IT-supported teaching method. Findings revealed that extraverts felt a higher perception of social presence th...

An algorithm is developd from the associated generator trees of basic dual solutions of a two-step transportation problem. This is completely appropiate for the “Balinski signature method” for the obtention of prime solutions of the two-step transportation problem

In this paper some general transportation models have been discussed and particularly a multi-choice cost stochastic transportation problem (STP) has been reviewed in the light of progressive research works of previous noteworthy researchers. In addition, an analytical approach for the optimal solution (OS) of the proposed stochastic transportation problem has been demonstrated. The analytical ...

We investigate the Nonlinear Generalized Transportation Problem (NGTP), where the transportation costs and the costs that depend on the amount of good delivered to the destination points are strictly convex functions. The amounts of goods change during the transportation process. This model may correspond, for example, with a congested network where the time costs are involved. First, we presen...

2 Introduction We use throughout the e+iωt convention. Acoustic liners are usually described in frequency domain by their impedance. If we use a numerical method in time domain, this is to be translated into an equivalent relation. This is not straightforward. For example, it is principally not possible for an non-real impedance to retain this value for all frequencies. We have to extend the im...

The density dependent flow and transport problem in groundwater is solved numerically by means of the mixed finite element scheme for the flow equation and an innovative time-splitting technique for the transport equation. The proposed approach, of global second order convergence, is used for the simulation of the movement of radioactive brines at the Lake Karachai (Russia).

Transportation Problem is an important problem which has been widely studied in Operations Research domain. It has been often used to simulate different real life problems. In particular, application of this Problem in NP-Hard Problems has a remarkable significance. In this Paper, we present the closed, bounded and non–empty feasible region of the transportation problem using fuzzy trapezoidal ...
