چکیده
Die Planung von fertigungstechnischen Prozessketten über Unternehmensgrenzen hinweg ist aufgrund technologischer Wirkbeziehungen zwischen Prozessschritten eine große Herausforderung. In diesem Beitrag wird Planungsmethode vorgestellt, die mit dezentralen Modulen unternehmensübergreifende Optimierung der Fertigungskosten ermöglicht. Zusätzlich werden Unsicherheiten durch Modellfehler sowie externe Einflüsse in Methode eingebunden. Dadurch kollaborative umgesetzt, zu robusten Ergebnissen führt. Planning of manufacturing process chains across companies is a great challenge due to technological interdependencies. This paper presents planning method enabling cross-company cost optimization with decentralized modules. addition, uncertainties model errors as well external factors made are integrated into the method. allows for collaborative and leads robust results.

Reasoning across scenarios in planning under uncertainty
Planning under uncertainty requires the adoption of assumptions about the current and future states of the world, and the preparation of conditional plans based on these assumptions. In any realistic domain, however, there will be an exponential explosion in the number of conditional plans required. One approach to this problem is to articulate a set of scenarios, which together are representat...
متن کاملBioethanol supply chain system planning under supply and demand uncertainties
Amixed integer stochastic programming model is established to support strategic planning of bioenergy supply chain systems and optimal feedstock resource allocation in an uncertain decision environment. The two-stage stochastic programming model, together with a Lagrange relaxation based decomposition solution algorithm, was implemented in a realworld case study in California to explore the pot...
متن کاملFuzzy optimization for supply chain planning under supply, demand and process uncertainties
In today’s global marketplace, individual firms do not compete as independent entities rather as an integral part of a supply chain. This paper proposes a fuzzy mathematical programming model for supply chain planning which considers supply, demand and process uncertainties. The model has been formulated as a fuzzy mixed-integer linear programming model where data are ill-known andmodelled by t...
