چکیده

Résumé en anglais This paper deals with formal modelling of Petri nets including shared resources. These phenomena appear widely in the production management context, for the modelling of manufacturing cells. But, they usually cannot be formally represented in dioid algebraic structures based on sets of scalars. In this paper, we design a method to describe such a phenomenon in a dioid of intervals. In fact, the resourcesharing problem is turned into a time uncertainty problem, regarding the access to the shared resource. In this new problem, time uncertainties are bounded and can be described by intervals. Both bounds of the behaviours of the studied production systems can be manipulated in the scope of the Zmax dioid, even though the original systems are not Zmax linear by essence.

Toward end-to-end fairness: a framework for the allocation of multiple prioritized resources

As flows of traffic traverse a network, they share with other flows a variety of resources such as links, buffers and router CPUs in their path. Fairness is an intuitively desirable property in the allocation of resources in a network shared among flows of traffic from different users. While fairness in bandwidth allocation over a shared link has been extensively studied, overall end-to-end fai...

Employing a Multi-Criteria Approach under Bankruptcy Conditions for Optimal Allocation of Shared Water Resources through Using Asymmetric Nash Bargaining Method

Management based on the flexibility, fairness, and sustainability characteristics of water resources may play a key role in preventing the continuation of the crisis process as well as reducing water users’ conflict. In the present research, the framework for the optimal allocation of shared water resources was presented using a combination of bankruptcy concepts and asymmetric Nash bargaining....

Optimal control of a hybrid production/remanufacturing system using one shared resource

In our problem, a company can use both a remanufacturing facility to sell returned products and a classical production facility to satisfy the demand that cannot be fulfilled by returns. Such systems are called hybrid production/remanufacturing systems and have received a growing attention in recent years. To perform production and remanufacturing, a company can use dedicated or shared resource...
