in order to implement the cellular manufacturing system in practice, some essential factors should be taken into account. in this paper, a new mathematical model for cellular manufacturing system considering different production factors including alternative process routings and machine reliability with stochastic arrival and service times in a dynamic environment is proposed. also because of t...

We investigate architectural properties required for supporting automatic service composition. First, composable service architecture will be described, based on modeling Web services as abstract machines supported by formally defined composition operators. Based on the proposed infrastructure we give several options for achieving automatic service composition by treating it as a search problem...

Retrial queueing systems are characterized by the requirement that customers finding the service area busy must join the retrial group and reapply for service at random intervals. This paper deals with the M/G/1 retrial queue subjected to breakdowns. We use its stochastic decomposition property to approximate the model performance in the case of general retrial times.

Supply chain transportation operations often account for a large proportion of product total cost to market. Such can be optimized by solving the Logistics Service Network Design Problem (LSNDP), wherein logistics service provider seeks cost-effectively source and fulfill customer demands products within multi-echelon distribution network. However, many industrial settings yield instances LSNDP...

 In many practical distribution networks, managers face significant uncertainties in demand, local price of building facilities, transportation cost, and macro and microeconomic parameters. This paper addresses design of distribution networks in a supply chain system which optimizes the performance of distribution networks subject to required service level. This service level, which is consider...

The service provision problem described in this paper comes from an application of distributed processing in telecommunication networks. The objective is to maximize a service provider's proot from ooering computational based services to customers. The services are built from software applications called subservices. The service provider has limited capacity of some resources and therefore must...

Naval research programs are focusing on a distributed architecture approach for successful migration of data from one region to another. This presents a challenging area of modeling and managing the distributed approaches. This article describes a service-based model, which comprises of two steps that are decomposition and orchestration, for effectively managing distributed cluster networks. Th...
