as route planning and resource handling. Using static domain analysis techniques, we have been able to identify certain commonly occurring subproblems within planning domains, making it possible to abstract these subproblems from the overall goals of the planner and deploy specialized technology to handle them in a way integrated with the broader planning activities. Using two such subsolvers o...

Nowadays, one of the greatest challenges companies have to face is the change towards flexible and demand-driven production. More information has to be handled and a considerable speed-up of development and manufacturing processes is needed. However, the actual situation is characterized by strong borderlines between process planning, production control and scheduling systems, caused by extreme...

A large body of work exists in process industry supply chain optimisation. We describe the state of the art of research in infrastructure design, modelling and analysis and planning and scheduling, together with some industrial examples. We will consider two network design type problems in more detail and then draw some conclusions about the degree to which different classes of problem have bee...

development of water resources projects are recognized as a basis of the development planning in the water resources sector. in addition to the quality of output results, following the schedule , continuous documentation and evaluation during the project is the one of the major challenges. in order to improve water study framework with high quality and scheduling and reduce the study process, t...

Train path (infrastructure), rolling stock and crew scheduling are three critical planning decisions in railway transportation. These resources are usually planned separately in a sequential process that typically starts from planning (1) train paths and goes further on to (2) rolling stock and (3) train drivers. Such a sequential approach helps to handle the complexity of the planning process ...

The MAV ’08 competition in Agra, India focused on the problem of using air and ground vehicles to locate and rescue hostages being held in a remote building. Executing this mission required addressing a number of technical challenges. The first such technical challenge was the design and operation of a micro air vehicle (MAV) capable of flying the necessary distance and carrying a sensor payloa...

The integrated problem of production and distribution scheduling is relevant in many industrial applications. Thus, many heuristics to solve this integrated problem have been developed in the last decade. Most of these heuristics use a sequential working principal or a single decomposition and integration approach to separate and solve subproblems. A heuristic using a multi step decomposition a...

Scheduling is the process of devising or designing a procedure for a particular objective, specifying the sequence or time for each item in the procedure. Qpical scheduling problems are railway time-tabling, project scheduling, production scheduling, and scheduling computer systems as in flexible manufacturing systems and multiprocessor scheduling. Further, there are a number of related problem...

Theoretical scheduling has reached a mature state but there are difficulties in using the theory in practice. One of the issues is the occurrence of disturbances. Studies have been done to investigate the possibility of using control chart techniques to detect disturbances in production planning and scheduling. Appropriate control chart techniques have been developed that avoid statistical prob...
