This work presents and evaluates a functional architecture and a framework for mapping service management policies and constraints into differentiated services (DiffServ) mechanisms. Several simulation scenarios described through the use of service policies are introduced and analyzed. It is shown that the use of service level management allows for efficient dynamic traffic engineering of DiffS...

Management policies for influenza outbreaks balance the expected morbidity and mortality costs versus the cost of intervention policies. We present a methodology for dynamic determination of optimal policies in a stochastic compartmental model with parameter uncertainty. Our approach is simulation-based and searches the full set of sequential control strategies. For each time point, it generate...

Because of different constraints such as the customers unceasing requirements, the large distribution of systems, the permanent modifications of the management environments themselves, etc., the environments devoted to the management of the inter-domain communications security must be generally dynamic and policy based. In this work, we will present a management environment, that is mainly base...

Asset management systems help public works agencies decide when and how to maintain and rehabilitate infrastructure facilities in a cost-effective manner. Many sources of error, some difficult to quantify, can limit the ability of asset management systems to accurately predict how built systems will deteriorate. This paper introduces the use of robust optimization to deal with epistemic uncerta...

Consider a dynamic decision making model under risk with a fixed planning horizon, namely the dynamic capacity control model. The model describes a firm, operating in a monopolistic setting and selling a range of products consuming a single resource. Demand for each product is time-dependent and modeled by a random variable. The firm controls the revenue stream by allowing or denying customer r...

Due to compliance and IT security requirements, company-wide identity and access management within organizations has gained significant importance in research and practice over the last years. Companies aim at standardizing user management policies in order to reduce administrative overhead and strengthen IT security. These policies provide the foundation for every identity and access managemen...
