The refinery business involves tasks spanning across several departments and requiring close coordination and collaboration among them. Present-day business decision support systems are tuned to individual departments and their work processes and are incapable of exploiting the intricate interdependencies among them. There is a need for a decision support system that provides a structured way t...

While ever-growing bio-ethanol production poses considerable challenges to the bioenergy supply chain, the risk of refinery operation disruptions further compromises the efficiency and reliability of the energy supply system. This paper applies discrete and continuous reliable facility location models to the design of reliable bio-ethanol supply chains so that the system can hedge against poten...

Supply chain management is one key area that has gathered much interest from both the academic and business communities. Today’s many uncertainties require that supply chains be nimble and resilient in reacting to disruptions for sustainable operations. We look at a refinery supply chain and present a strategy for recovering from disruptions by heuristic rescheduling. This is important as refin...

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...

Unpublished AIChE shall not be responsible for statements or opinions contained in papers or printed in its publications ABSTRACT The refinery business involves tasks spanning across several departments and using large amounts of data. These processes include crude procurement, logistics scheduling, storage (tank) scheduling and crude scheduling. Integrated decisions based on the entire supply ...

In the face of highly competitive markets and constant pressure to reduce lead times, enterprises today consider supply chain management to be the key area where improvements can significantly impact the bottom line. More enterprises now consider the entire supply chain structure while taking business decisions. They try to identify and manage all critical relationships both upstream and downst...

In the literature, optimization models deal with planning and scheduling of several subsystems of the petroleum supply chain such as oilfield infrastructure, crude oil supply, refinery operations and product transportation. The focus of the present work is to propose a general framework for modeling petroleum supply chains. As a starting point, processing units are modeled based on the framewor...
