A non-linear multi-objective transportation problem (NMOTP) refers to a special class of non-linear multi-objective problems. In this paper we review goal programming (GP) and fuzzy programming (FP) as two approaches for solving (NMOTP). Meanwhile, by extending Mohamed’s idea about fuzzy goal programming (FGP), we propose a fuzzy goal programming approach to solve the non-linear multi-objective...

stability of foundations near slopes is one of the important and complicated problems in geotechnical engineering, which has been investigated by various methods such as limit equilibrium, limit analysis, slip-line, finite element and discrete element. the complexity of this problem is resulted from the combination of two probable failures: foundation failure and overall slope failure. the curr...

the aim of the present paper is to evaluate the influence of the soil- foundation- structure interaction (sfsi) effects on the component demand modifier factor of concrete gravity beams based on asce 41-06 standard. to this end, the beam on the nonlinear winkler foundation approach is employed which is a simple and efficient method. at first, four sets of 3-, 6-, 10- and 15-storey concrete mome...

Multi objective quadratic fractional programming (MOQFP) problem involves optimization of several objective functions in the form of a ratio of numerator and denominator functions which involve both contains linear and quadratic forms with the assumption that the set of feasible solutions is a convex polyhedral with a nite number of extreme points and the denominator part of each of the objecti...

Sensor nodes are densely deployed to accomplish various applications because of the inexpensive cost and small size. Depending on different applications, the traffic in the wireless sensor networks may be mixed with timesensitive packets and reliability-demanding packets. Therefore, QoS routing is an important issue in wireless sensor networks. Our goal is to provide soft-QoS to different packe...

linear programming has been employed in many areas of constrained optimization including in agricultural planning for a long time. one of the most important disadvantages of such a method is that there is only one optimum solution for a given objective function and constraints set. another method named nearly optimal linear programming has been developed for solving the problem. this method can...

in this paper, a mathematical method is proposed to formulate a generalized ordering problem. this model is formed as a linear optimization model in which some variables are binary. the constraints of the problem have been analyzed with the emphasis on the assessment of their importance in the formulation. on the one hand, these constraints enforce conditions on an arbitrary subgraph and then g...

The co-operative formulation of a nonlinear bilevel program involving nonconvex functions is considered and two equivalent reformulations to simpler programs are presented. It is shown that previous literature proposals for the global solution of such programs are not generally valid for nonconvex inner programs and several consequences of nonconvexity in the inner program are identified. In pa...
