| Abstract | This paper presents new formulations of the approximate mean value analysis (MVA) algorithms for the performance evaluation of closed product-form queueing networks. The key to the development of the algorithms is the derivation of vector nonlinear equations for the approximate network throughput. We solve this set of throughput equations using a nonlinear Gauss-Seidel type distributed algorithms, coupled with a quadratically convergent Newton's method for scalar nonlinear equations. The throughput equations have enabled us to: (a) derive bounds on the approximate throughput; (b) prove the existence, uniqueness, and convergence of the Schweitzer-Bard (S-B) approximation algorithm for a wide class of monotone, single class networks, (c) establish the existence of the S-B solution for multi-class, monotone networks, and (d) prove the asymptotic (i.e., as the number of customers of each class tends to ∞) uniqueness of the S-B throughput solution, and the asymptotic convergence of the various versions of the distributed algorithms in multi-class networks with single server and infinite server nodes. The asymptotic convergence is established using results from convex programming and convex duality theory. Extension of our algorithms to mixed networks is straighfoward. Only multi-class results are presented in this paper. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
