【摘要】：随着我国新型工业化和城市化的不断推进，建筑施工企业处于多项目建设环境下的情形越来越常见。因而，大部分施工企业为了从激烈的市场竞争中谋求生存并立稳脚跟，逐渐把项目管理的目光转移到多项目管理上来，但是企业的多项目管理还处于初步阶段，在面对多项目管理的过程时还不能很好的解决诸如资源约束下的进度冲突问题。企业从传统的单项目管理转移到多项目管理的同时，项目之间会因为任务的相似性或者相同性而需要用到企业的某种资源或者某些资源，可是企业的资源是有限的，不可能同时满足项目对资源的需求，这样就会导致得不到资源分配的项目的进度被拖延。如何利用有限的资源最大限度的满足多项目进度的要求以及在规定的进度计划要求内如何合理有效地使用资源是多项目管理的难点和重点。本文首先阐述了多项目管理的基本理论和相关知识，根据这些理论基础说明现今建筑施工企业进行多项目管理的迫切性和必要性。在多项目管理时不得不考虑资源的有限性，如果项目不能及时得到应有的资源就会延迟完工，而且一旦个别项目被拖延进度就会产生级联效应导致其他与之相关的后续项目或工序的进度被拖延，所以多项目的进度管理就显得尤为重要。因此接下来本文研究了多项目进度管理时企业所遇到的问题，分析了制约多项目进度的各种因素。然后本文研究了已有的多项目调度的模型和方法，并建立了适合现今建筑施工企业资源约束下的多项目进度集成与资源协调控制模型，设计了用遗传算法分析多项目进度集成与资源协调控制的操作步骤，运用遗传算法求解模型，，紧接着结合案例来说明所建模型在解决多项目管理时的可行性和有效性。本文的最后基于对多项目进度管理与资源协调问题的研究提出了多项目进度集成与资源协调控制的对策。
[Abstract]:With China's new industrialization and city change steadily, building construction enterprises in the construction of multi project environment more and more common. Therefore, most of the construction enterprises in the fierce competition in the market to survive and firmly, gradually put attention to the project management of multi project management, but the enterprise multi project management is still in the initial stage, in the face of the process of multi project management is not a good solution such as resource
Under the constraints of scheduling conflicts. The transfer of enterprises from the traditional single project management to multi project management at the same time, because of the similarity between items or the same task and need to use some resources of enterprises or some resources, but the resources are limited, can not meet the project demand for resources, such will lead to not resource allocation project progress has been delayed. How to utilize the limited resource to meet the requirements of multi project schedule and in
The provisions of the schedule requirements in how reasonable and effective use of resources is the emphasis and difficulty of multi project management. This paper firstly expounds the basic theory of project management and related knowledge, according to these theories explain the urgency and necessity of multi project management of the building construction enterprise. In the multi project management to consider limited resources, if the project can not be completed in time and resources will be delayed, once the individual projects have been delayed progress will have cascading effects lead to other follow-up projects related or the process of progress has been delayed, so multi project schedule management is particularly important. Therefore in this paper multi project schedule management in the enterprise the problems encountered, analyzes the various factors restricting the multi project schedule. Then this paper studies the existing model of multi project scheduling And the method, and establishes suitable for multi project schedule integration and resource coordination control model nowadays construction enterprises under resource constraints, the design of multi project schedule integration and resource coordination control procedure using genetic algorithm, using genetic algorithm to solve the model, and then combined with the case to illustrate the feasibility of solving the model in multi project management time and effective. Finally, based on the research of multi project management and resource coordination problems and puts forward some countermeasures for integration and resource coordination and control of multi project schedule.
