چکیده

Traditional optimization of production system and utility system is carried out separately which cannot ensure that the entire refinery system is optimized globally. In this paper, a novel integrated approach is proposed to optimize process production planning and utility system operation simultaneously. A refinery-wide mixed integer nonlinear programming model is proposed and the traditional method and improved integrated method are compared. A real industrial example is conducted to demonstrate the effect of the proposed mathematical model. The results suggest that the integrated approach can provide not only significant benefits but also better energy utilization.

A Hierarchical Production Planning and Finite Scheduling Framework for Part Families in Flexible Job-shop (with a case study)

Tendency to optimization in last decades has resulted in creating multi-product manufacturing systems. Production planning in such systems is difficult, because optimal production volume that is calculated must be consistent with limitation of production system. Hence, integration has been proposed to decide about these problems concurrently. Main problem in integration is how we can relate pro...

An improved genetic algorithm for multidimensional optimization of precedence-constrained production planning and scheduling

Integration of production planning and scheduling is a class of problems commonly found in manufacturing industry. This class of problems associated with precedence constraint has been previously modeled and optimized by the authors, in which, it requires a multidimensional optimization at the same time: what to make, how many to make, where to make and the order to make. It is a combinatorial,...

Supply Chain Optimization of Petroleum Refinery Complexes

Production planning is a very important step in managing the operation of a single refinery and their complexes. Despite its significance, few contributions have been found in literature and the existing ones rely on linear models. Pinto et al. (Comp. Chem. Engng. 24, 2259-2276, 2000), presented a superstructure that represents a general topology and allows the implementation of nonlinear proce...
