摘要：

为了反映本地任务到达和失效对网格任务执行的影响，采用确定与随机Petri网描述了制造资源的运行状态，并给出了不考虑本地任务到达情况下制造资源的网格任务可靠性表达式。对于考虑本地任务到达的情况，采用蒙特卡洛仿真方法，研究了在本地任务优先策略下制造资源的网格任务可靠性问题，分析了本地任务到达率、本地任务执行率等因素对任务可靠性的影响，从而为网格资源管理系统更好地实现网格任务调度提供依据。

Abstract:

To describe the impact of local task arrivals and failures on grid

task execution,a state analysis of manufacturing resources based on deterministic and stochastic Petri net was discussed and the formula of grid task reliability without considering local task arrival was given.In order to describe the influence of local task arrival,

research on grid task reliability based on the Monte Carlo simulation was studied and the influence of local task arrival rate and local task execution rate on grid task reliability was analyzed.The simulation results can provide some information to grid resource management so as to make grid task scheduling better.

Key words: manufacturing grid;manufacturing resource;Monte Carlo simulation;grid task reliability
