摘要
本文基于集中式能力约束设置方法的不足,采用分散式能力约束缓冲设置法,考虑任务延期的积累性,将能力约束缓冲设置到关键任务之前;针对前置式分散能力约束缓冲,提出综合考虑关键资源紧张度、关键任务网络复杂度、关键任务间的间隙度和关键任务的自由时间等因素来计算能力约束缓冲的尺寸大小。模拟结果表明:本文提出的能力约束缓冲的计算方法在不确定性大的情况下,可以有效地避免项目的延期和缓冲区的溢出。
Setting method based on centralized capacity constraints,distributed capacity constraint buffer set method,and considering the delaying of the task,accumulating,buffer capacity constraints can be set to the key tasks before; Buffer against superposed dispersing ability constraint,we present a comprehensive consideration of critical resources tensity,mission-critical network complexity,the degree of clearance between key tasks,and such factors as the key task of free time to calculate the size of the buffer capacity constraints. Simulation results show that the proposed the calculation method of buffer capacity constraints in the case of large uncertainties,can effectively avoid project delay and buffer overflow.
