We consider a fractional program with both linear and quadratic equation in numerator and denominator having second order cone (SOC) constraints. With a suitable change of variable, we transform the problem into a second order cone programming (SOCP) problem. For the quadratic fractional case, using a relaxation, the problem is reduced to a semi-definite optimization (SDO) program. The p...
in this paper the issue of evaluating iranian oil refineries performance has been discussed. the research is based on math modelling by operational research techniques. to do so, of the proposed scenarios and different math programming models, a model is made by combining dea with goal programming techniques that compared with the old classical dea models which measures the efficiency and produ...
Background and purpose: Nowdays in almost all organizations, resources are allocated based on traditional methods, personal experiences and mental reasoning power. This causes some dissatisfaction among people and have no generalization ability and mathematical basis. The objective of this research was to propose a fuzzy goal programming model in resource allocation at the university-educa...
