Abstract: Based on the research status of analyzing multi-project parallel task，with the problem of resource distribution，the multi-project task scheduling process with the restriction of human resource is described，which is aimed at the limited human resource in the multi-management in enterprise.Then the multi-project task is arranged，based on the back-scheduling method of virus evolutionary genetic algorithm，obtaining the engineering solution before the engineering deadline，and achieving the optimal configuration of human resource in the multi-project parallel task management.

Key words: virus evolutionary genetic algorithm, multi-project, configuration of human resource

摘要： 在分析多项目并行任务资源分配的研究现状基础上，针对企业多项目管理中有限人力资源配置这一核心问题，对人力资源限制下多项目任务调度的过程进行了数学描述，并采用基于病毒遗传算法的倒排法对多项目任务进行排程，力求在满足工期的前提下得出较优的工程解，实现多项目并行任务管理中人力资源的优化配置。
