Approaches for optimizing surrogate models considering uncertain parameters

Bayesian approaches for optimizing warranty length of products

‎Today's manufacturers face increasingly intense competition and to remain profitable they needed to design‎, ‎develop and produce high reliable products‎. ‎One way by which manufacturers attract consumers to their products is by providing warranties on the products‎. ‎Consumers are willing to purchase a longer warranty period product‎. ‎While maintaining such a policy needs very high cost for ...

Comparing different approaches for solving optimizing models with significant nonlinearities

The property of saddle-path instability often arises in economic models derived from optimising behaviour by individual agents. In the case when underlying functional forms are nonlinear, it is likely that the stable and unstable arms defining the saddle-path dynamics will also have nonlinear properties. While closed-form analytic solutions can always be derived for linearised deterministic ver...

Interval Approaches for Uncertain Reasoning

This paper presents a framework for reasoning using intervals. Two interpretations of intervals are examined, one treats intervals as bounds of a truth evaluation function, and the other treats end points of intervals as two truth evaluation functions. They lead to two different reasoning approaches, one is based on interval computations, and the other is based on interval structures. A number ...

Developing Robust Project Scheduling Methods for Uncertain Parameters

A common problem arising in project management is the fact that the baseline schedule is often disrupted during the project execution because of uncertain parameters. As a result, project managers are often unable to meet the deadline time of the milestones. Robust project scheduling is an effective approach in case of uncertainty. Upon adopting this approach, schedules are protected against po...
