  摘要:软件项目管理人员须对软件过程中的各种资源进行优化调度,但依靠主观判断和个人经验的资源调度方法具有不稳定性和不可靠性,需要提供客观可靠的软件过程资源调度方法和工具。基于收益的资源调度优化方法通过对软件过程的资源调度进行建模,描述和定义投入资源产生的收益,分析软件过程中活动、资源和收益的各种约束关系,采用基于动态规划的优化算法以较高效率完成资源调度,使资源在软件过程中有效利用。

  Abstract:Resource scheduling in software processes is one of principle challenges in software project management. Resource scheduling based on subjective discretion and personal experiences of project managers is inherently instable and unreliable. In order to control and optimize software processes effectively, an objective and reliable approach to resource scheduling is very helpful. Benefit-based approach to resource scheduling optimization proposed a new model of resource scheduling in software process, described and defined benefits of resource investment, analyzed constraints and relations among activities, resources and benefits. Designed an efficient optimization algorithm derived from dynamic programming, which could be added or integrated into real software engineering environments.
