Ideas for modeling and simulation of supply chains with Arena

Abstract: This paper presents a research project being developed at the Industrial and Systems Engineering Graduate Program at the Catholic University of Parana (Brazil). The objective is to develop a system to aid professionals from management and logistics areas to evaluate the performance of supply chains through computer simulation. Among the several possibilities for analysis, simulation can allow one to perform detailed studies on the bullwhip effect in supply chains, caused by the demand variation from the point-of-sale to the suppliers. Two performance measures are of particular interest: average inventory level and service level, both for each stage at and for the whole supply chain. The structure considered in this project is the traditional supply chain composed by suppliers, manufactures, distributors (or wholesalers), retailers and customers. A first version of the proposed arena simulation models is under development and is presented in this paper.

System and method for workforce requirements management

Abstract: The present invention provides a workforce requirements management system and method that determines future demand for service related transactions or activity and optimizes the planning of workforce to meet the future demand. Initially, the workforce requirements management system reviews historical data regarding transaction volume and service activity to determine the future demand for such transactions or service activities. The historical data may come from a conventional enterprise resource planning application and/or include demographic data and/or economic indicators. The workforce requirements management system can optimize a forecast by isolating certain variance factors and refining the forecast accordingly. A forecast can also be optimized by estimating transaction times and correlating variance factors with estimated transactions times. Additionally, the workforce requirements management system can optimize the forecast based on the queuing model employed for the particular service. Finally, the workforce requirements management system can create a long term resource plan that identifies the most efficient balance of full time equivalent and part time equivalent staffing levels to meet the long term forecast need at the desired service level at the lowest overall labor cost. Specific outputs generated by the workforce requirements management system include a transaction forecast, a resource forecast, a resource plan, and a resource schedule.

Supporting QoS-based discovery in service-oriented Grids

Abstract: In this paper the service abstraction is extended to support quality of service (QoS) attributes - and implemented in the Grid QoS Management (G-QoSM) framework. The framework supports three main functions: (1) providing mechanisms for establishing QoS guarantees via service level agreements (SLAs), (2) enabling QoS management on allocated QoS-aware services, and (3) supporting discovery of services based on QoS attributes. The framework relies on each service offering both a "functional" interface and a "management" interface. The functional interface provides attributes on how a service is to be invoked and how it returns results, whereas the management interface is used to provide QoS attributes and performance characteristics associated with a service. The focus of this paper is on implementing a QoS-based service discovery system, which utilises an extended version of the universal description, discovery and integration (UDDI) registry.

A Framework for Pre-computated Multi-Constrained Quickest QoS Path Algorithm

Abstract: The era of advance computer networks and advance communication leads the technology to new heights and the algorithms used for the routing needs to be updated side by side parallel with the advancement. This paper presents the new multi-constrained routing algorithm which gives quality of service full-fill the service level agreements with the user. Finding a multi-constrained path is a NP-complete problem, but still the presented algorithm gives the feasible path for the routing in a given polynomial time. Furthermore the performance comparison shows the best results with presented approach and existed approach.
