A COMPARATIVE STUDY OF M| M | 1 AND M| M | C MODELS FOR B2C WITH SUPPLY CHAIN PROCESS

With the emerging technology of electronic commerce, most of the business companies positively tend to offer services to their clients dealing in B2C e-commerce. We pro- posed four models for business to consumer (B2C) with supply chain management. First two models are M |M |1 with and without server breakdown and other models are M |M |C with and without server breakdown. During service when the server breakdown, the re- pairing process of the server begins immediately. During repair period the server serves the customer with slow rate and service period follows exponential distribution. Then numerical results are also illustrated various system performances are calculated.
