TLDR
In this paper, the authors describe how a generic multi-period optimization-based decision support system can be used for strategic and operational planning in process industries, based on five fundamental elements: materials, facilities, activities, time periods and storage areas.Abstract:
We describe how a generic multi-period optimization-based decision support system can be used for strategic and operational planning in process industries. Built on five fundamental elements—materials, facilities, activities, time periods and storage areas—this system requires little direct knowledge of optimization techniques to be used effectively. Results based on real data from an American integrated steel company demonstrate significant potential for improvement in revenues and profits.read more
