Approximate Dynamic Programming by Linear Programming for Stochastic Scheduling

In stochastic scheduling, we want to allocate a limited amount of resources to a set of jobs that need to be serviced. Unlike in deterministic scheduling, however, the parameters of the system may be stochastic. For example, the time it takes to process a job may be subject to random fluctuations. Stochastic scheduling problems occur in a variety of practical situations, such as manufacturing, ...

A Maintenance Packaging and Scheduling Optimization Method for Future Aircraft

This paper proposes an optimization method for aircraft maintenance tasks packaging and scheduling integrated in an aircraft lifecycle simulation. It is demonstrated that the developed methods are feasible to model a prognosis-based maintenance concept. Such maintenance concepts are a prerequisite for a profitable application of prognostics and health management systems in future aircraft. The ...

Stressing Symbolic Scheduling Techniques within Aircraft Maintenance Optimization

Scheduling, or planning, is widely recognized as a very important step in several domains such as high level synthesis, real-time systems, and every-day applications. Given a problem described by a number of actions and their relationships, finding a schedule, or a plan, means to find a way to perform all the actions minimizing a specific cost function. The goal of this paper is to develop, ana...
