In this paper we try to introduce a new approach and study the notion of efficiency under a multi objectives linear programming problem in the university by using analysis of hierarchy process (AHP)‎. ‎To this end‎, ‎we first extract some effective parameters due to efficiency offices in university and then prioritized these parameters by the AHP method‎. ‎Hence‎, ‎we could classify the most im...

A procedure is presented that synthesizes fractional crystallization separation processes to obtain pure solids from multi-component solutions. The method includes a procedure to generate a network flow model to identify alternative process designs for fractional crystallization. The main advantage of this systematic procedure with respect to other reported procedures is using non-equilibri...

Reverse logistics planning plays a crucial role in supply chain management. Stochasticity different parameters along with time horizon can be challenge solving reverse problems. This paper proposes multi-stage, multi-period lot sizing decisions under uncertainties. The main uncertain factors are return and demand quantities, quality. Moment matching method was adopted to generate discrete set o...

[1] corresponding author e-mail: [email protected]   [1] corresponding author e-mail: [email protected]   lot-sizing problems (lsps) belong to the class of production planning problems in which the availability quantities of the production plan are always considered as a decision variable. this paper aims at developing a new mathematical model for the multi-level capacitated lsp w...

Modern multi-core machines are conceived to efficiently execute explicitly parallel assembly programs. Current technology is moving away from instruction-level parallelism, exploitable without changes in the software, toward task-level parallelism requiring modifications in programs. In this context exploiting parallelism entails either exploiting new parallelizing toolchains, or programming in...
