In the course of globalization, many enterprises change their strategies and are coupled in partnerships with suppliers, subcontractors and customers. This coupling forms supply chains comprising several geographically distributed production facilities. Production planning in a supply chain is a complicated and difficult task, as it has to be optimal both for the local manufacturing units and f...

People produce long sequences such as speech and music with incremental planning: mental preparation of a subset of sequence events. The authors model in music performance the sequence events that can be retrieved and prepared during production. Events are encoded in terms of their serial order and timing relative to other events in a planning increment, a contextually determined distribution o...

We study the problem of recovering a production plan after a disruption, where the disruption may be caused by incidents such as power failure, market change, machine breakdown, supply shortage, worker no-show, and others. The new recovery plan we seek after has to not only suit the changed environment brought about by the disruption, but also be close to the initial plan so as not to cause too...

Theories of language production need to account for how speakers produce prosodic structure. Very few models have addressed the role of prosodic phrasing in speech planning, and little experimental work examining this question has been conducted so far. Four studies designed to investigate the effect of phrase length and prosodic phrasing on speech planning are presented. The first experiment e...

Due to the progress of high technology, TFT-LCD (Thin Film Transistor – Liquid Crystal Display) has been widely put in use recently. The manufacturing technology of the TFT-LCD industry mainly consists of array, cell, module processes, in which there exists special characteristics such as different objectives of individual process’s scheduling, complexity of manufacturing processes, and multi-s...

Multistage stochastic programming is a key technology for making decisions over time in an uncertain environment. One of the promising areas in which this technology is implementable, is medium term planning of electricity production and trading where decision makers are typically faced with uncertain parameters (such as future demands and market prices) that can be described by stochastic proc...

Preventive maintenance is the essential part of many maintenance plans. From the production point of view, the flexibility of the maintenance intervals enhances the manufacturing efficiency. On the contrary, the maintenance departments tend to know the timing of the long term maintenance plans as certain as possible. In a single-machine production environment, this paper proposes a simulation–o...
