The Study Of Multi-Project Schedule Optimizing And Resource Balancing Method

With the rapid development of economy and technology, Chineseenterprises have tended to become diversified and large-scale. In recentyears, the enterprises begin to assume more and more projects, andaccompanied by the size of these projects increasing, but it is alsohighlighted some bad phenomena such as project can not be completed ina timely manner, budget overruns seriously or allocation of resourcesbecomes irrational etc. Therefore, in order to make more effective use oflimited resources, multi-project management as a new projectmanagement approach emerged, and it can make Low-cost and highprofit for enterprises.The paper using the theory of modern project management guides usto study the way of project schedule optimization, and establishes thecorresponding multi-project schedule optimization model which dividedinto three layers in the resource-constrained conditions, finally, using theheuristic algorithm to shorten the project duration and distribute therequired resources balanced. The model that established in this paper useshierarchical model which divided into three levels: the first-sub goal is tomake the duration of each project shorter than it’s predetermined duration;the second-sub goal is to make the consumption of shared resources keepin a balanced level; the third-sub goal is to develop a specific schedule bythe project leader according to the limited resources and scheduledduration to shorten the actual duration of this project, so that they can geta minor punishment because of durations been delayed or get a rewardbecause of durations been advanced.In addition, this paper established the priority model by analyzingthe various factors which affected the progress of the project. This priority model will be used to arrange the start-time of each task bycalculating priority coefficient when the shared resources were limited. Inshort, these multi-project schedule optimization models can help developproject schedule and make resource balanced use, providing support forthe overall optimization of the projects.
