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...

In this article the place and capacity of combined heat and power [CHP] prediction unit wasdetermined dynamically with use of modified particle swarm optimization (MPSO). It was done inoptimization palace and with a capacity of CHP as a production resource with the aim to increasethe reliability capacity. Decrease the loss and provide the electrical and thermal energies ofindustrial city. The f...

In this paper, we study a supply chain scheduling problem that simultaneously considers production scheduling and product delivery.  jobs have to be scheduled on a single machine and delivered to  customers for further processing in batches. The objective is to minimize the sum of the total weighted number of tardy jobs and the delivery costs. In this paper, we present a heuristic algorithm (HA...

The theory of constraints is an approach to production planning and control that emphasizes on the constraints to increase throughput by effectively managing constraint resources. One application in theory of constraints is product mix decision. Product mix influences the performance measures in multi-product manufacturing system. This paper presents an alternative approach by using of goal pro...

This paper investigates a procedure for identifying all efficient hyperplanes of production possibility set (PPS). This procedure is based on a method which recommended by Pekka J. Korhonen[8]. He offered using of lexicographic parametric programming method for recognizing all efficient units in data envelopment analysis (DEA). In this paper we can find efficient hyperplanes, via using the para...
