This contribution presents the modeling and optimization of the operation of production plants that are coupled via distribution networks and applies it to a part of the petrochemical production site of INEOS in Köln in Germany. The problem is formulated as a mixed-integer linear problem and solved to generate an optimal monthly plan for a set of plants, tanks, and loading/unloading facilities, while...
Large interconnected production sites typically consist of many plants that are physically coupled by networks of shared resources. An optimal site‐wide allocation of shared resources is key to a resource‐, energy‐, and cost‐optimal operation. Market‐based coordination can find the site‐wide optimum with limited data exchange between the subsystems and thus ensures confidentiality. In this contribution,...
Site-wide resource allocation among different partially autonomous production plants in the process industries can be realized by price-based coordination. The individual production plants pursue their own objectives and only report the amount of shared resources that they want to produce or consume as a response to the price signals. In an iterative procedure, known as tatonnement process, a central...
