Game Theory Based Multi-attribute Negotiation between MA and MSAs

Part VI: Services, Supply Chains and OperationsInternational audienceThis paper focuses on the multi-attribute negotiation between Manufacture Agent (MA) and Material Supplier Agent (MSA) of supply chain network (SCN). A modified two-stage negotiation protocol is proposed based on the two-stage negotiation protocol proposed in the previous work. The negotiation between MA and MSAs, where the quantity of the order of MA depends on the demand of Consumer Agent (CA), are discussed to decide the final supplier and the final strategies. The strategies of the negotiation are the wholesale price of the product, the quantity of the order, and the lead time. The final solution is solved by finding the Stackelberg equilibrium of MA-Stackelberg game. Numerical case is provided to illustrate the proposed protocol

Multiagent System-Based Simulation Method of Service Diffusion in Consumer Networks – Application to Repeatedly Purchased Plural Services –

Part VI: Services, Supply Chains and OperationsInternational audienceThis paper presents a simulation based analysis method for service diffusion in consumer networks. Services with good qualities do not always diffuse because service quality is often unstable because of the nature of service delivery systems involving human. Consumers cannot also confirm the quality of service before purchase because service has no shape. Therefore, it is necessary to study diffusion process of service by computer simulations to clarify the process of acceptance among consumers in consideration with heterogeneity of consumer utility due to the unstable service quality. This paper proposes a multiagent-based model for diffusion of plural competing services repeated purchased in consumer networks including heterogeneity of consumer utility. It is verified that the heterogeneity of consumer utility and network structure affect service diffusion process in the results of computer simulations. Finally, the diffusion process of services is concluded in terms both of the number of service and repetition of service purchase

Improving Customer’s Subjective Waiting Time Introducing Digital Signage

Part VI: Services, Supply Chains and OperationsInternational audienceIn the 1970s, the Japanese restaurant industry introduced the chain store system, which was later introduced into the retail industry in the USA to enhance productivity [1] [2]. The chain store system was designed to realize “low-cost operations”. For instance, chain store restaurants simplify and automate service operations to reduce the number of service staff. Moreover, they standardize service operations by introducing service manuals for use in training part-time staff. Prices of dining decreased throughout chain store systems, and Japanese consumers came to enjoy restaurants casually. Consequently, the market scale of the Japanese restaurant industry expanded from 8 trillion yen to 250 trillion yen during the 1970s to 1990s. Restaurants in Japan numbered approximately 737,000 in 2006 [3]
