The service-oriented architecture (SOA) has been quite prevailing in enterprise applications development, integration, and deployment. In SOA environment, the complex problem can be solved by combining available individual services and ordering them to best suit their problem requirements. Service composition accelerates rapid enterprise application(More)
The introduction of Parallel and Distributed Simulation (PADS) has added great impetus to efforts to use simulation as a strategic tool to support decision making in supply chain management. However, due to the heterogeneity and the dynamic nature of supply chains, there are many challenges that must be overcome if supply chain simulation is to play an(More)
For supply chain optimization, as a key determinant of strategic resources mobility along the value-added chain, simulation is widely used to test the impact on supply chain performance for the strategic level decisions, such as the number of plants, the modes of transport, or the relocation of warehouses. Traditionally, a single centralized model that(More)
Real-time planning and scheduling in a shop floor are not easy to accomplish due to the concurrent flow of various parts as well as sharing of different types of resources. Multi-pass scheduling is a well known method for solving the aforementioned problem. Its success depends largely on selecting the best decision-making rule fast and effectively. Although(More)
Parallel and distributed simulation is concerned with the efficient execution of large-scale discrete event simulation models on multiprocessors and distributed platforms. After the development of World Wide Web (WWW), many efforts in parallel and distributed simulation have been made for modeling, particularly building simulation languages and creating(More)
Lack of interoperability among enterprise applications has become the biggest impediment to their seamless integration. Although inter-enterprise applications are carefully designed and implemented, a close verification on whether they interoperate should be performed before their deployment. Application developers must be able to effectively identify and(More)
