IBM General Business Simulation Environment (GBSE) is a supply chain simulation tool developed by IBM China Research Lab. It can capture supply chain dynamics with finest level of granularity and provides great insights to a supply chain's real operations. GBSE is designed for tactical level decision making; it is proper for supply chain what-if analysis(More)
In this paper, we present a framework for developing discrete-event simulation models for resource-intensive service businesses. The models simulate interactions of activities of demand planning of service engagements, supply planning of human resources, attrition of resources, termination of resources and execution of service orders to estimate business(More)
This paper describes an innovative framework, iFAO-Simo, which integrates optimization, simulation and GIS (geographic information system) techniques to handle complex spatial facility network optimization problems ever challenged from retailing, banking and logistics nowadays. At the top level of iFAO-Simo, an optimization engine serves to generate and(More)
Supply chain managers today face an unremitting challenge to their capabilities in both the volume and complexity of factors to be reconciled. In order to achieve more effective decision making, it is very necessary to link strategic objectives to operational actions. However, little is available to guide managers in translating a set of objectives into(More)
We model supply chain of an industry solution equipment manufacturer, where the merchandise is sold worldwide, but suppliers are mostly located in Asia. The preferred shipment of supply is the ocean shipment, and it takes about 5 weeks. Premium air shipment can be used to expedite delivery, but it costs substantially higher. To hedge against variability of(More)
