Modeling and analysis of the effects of QoS and reliability on pricing, profitability, and risk management in multiperiod grid-computing networks |
Abstract:
In this paper we develop a network equilibrium model for optimal pricing and resource allocation inComputational Grid Network. We consider a general network economy model with Grid Resource Providers,Grid Resource Brokers and Grid Users. The proposed framework allows for the modeling and theoretical analysisof Computational Grid Markets that considers a non-cooperative behavior of decision-makers in the same tier ofthe grid computing network (such as, for example, Grid Resource Providers) aswell as cooperative behaviorbetween tiers (between Resource Providers and Grid Brokers). Weintroduce risk management into the decisionmaking process by analyzing the decision-marker's reliability and quality of service (QoS) requirement. Weanalyze resource allocation patterns as well as equilibrium price based on demand, supply, and cost structureof the grid computing market network. We specifically answer the following questions with several numericalexamples: How do system reliability levels affect the QoS levels of the service providers and brokers undercompetition? How do system reliability levels affect the profits of resource providers and brokers in acompetitive market? How do system reliability levels influence the pricing of the services in a competitiveenvironment? How do users' service request types, QoS requirements, and timing concerns affect users'behaviors, costs and risks in equilibrium? How does the market mechanism allocate resources to satisfy thedemands of users? We find that for users who request same services certain timing flexibility can not onlyreduce the costs but also lower the risks. The results indicated that the value of QoS can be efficiently pricedbased on the heterogeneous service demands. |
