Abstract :
Equipment grid and equipment pool model of equipment grid are introduced. The process from submitting a job in equipment grid to obtaining of results is analyzed. A fuzzy scheduling method is proposed in equipment pool when a job is submitted to one of equipments within a pool. Fuzziness of this method lies in vagueness of users´ appraisals about experiment results and execution quality of equipments. Equipment in a pool has a probability, which can be adjusted by users´ fuzzy appraisals, to be scheduled. Users´ feedback information is used in this paper to improve execution quality. Some algorithms are provided to increase utilization ratio of equipments with high execution quality and decrease utilization ratio of those with poor execution quality. From simulation result, it is obvious that this method and related algorithms can provide users more chances with high execution quality.
