In this paper we describe our approach to the second phase of SWS Challenge 2006. We present the WebML design of the mediator and its implementation by the means of the CASE tool WebRatio; furthermore, we discuss the integration of Glue WSMO discovery engine in our approach.

Nevertheless, the transportation cost accounts for a major part of supply chain cost, especially when transportation companies offer freight rate discount schedule...

Service network design is critical to the profitability of express shipment carriers. In this paper, we consider the problem of designing the integrated service network for premium and deferred express shipment delivery. Related existing models adapted to this problem are intractable for realistic problem instances, requiring excessive computer memory and solution times. We extend existing mode...

This paper derives optimal production-shipment policy for a single-producer multi-retailer integrated inventory model with rework. We assume that a product is manufactured by a producer. All items are screened for quality assurance. Random defective items will be picked up and reworked in the same cycle when regular production ends. Upon entire lot is quality assured, multiple shipments are del...
