Abstract: With the advent of grid model based on open grid service architecture, the problem about job matching and scheduling has increasingly become important. This paper proposes a service-oriented grid scheduling framework, introduces stochastic process theory, and gives a dynamic algorithm about job matching and scheduling. This solves the dynamic problem in grid computing efficiently.

Key words: Grid service, Poisson stochastic process, Scheduling, Matching, Queuing
