Abstract

A resource allocation method is proposed to determine the proper number of resources added to each resource class with cost constraint in order to optimize workflow time performance. The average throughput time of workflow instances is used to measure the workflow time performance. An approach which calculates the average throughput time of workflow instances is proposed. An improved genetic algorithm is presented to realize the allocation method. Experimental results show that the algorithm has good evolution performance and is superior to other allocation methods.
