【摘要】：随着科技的日益发展,市场竞争也越来越趋于白热化,机械制造企业为了确保在市场上占据一席之地,求得生存和发展,必须加快产品的更新换代,提高产品的创新研发的效率。如何提高企业研发的能力和工作的效率,其关键就在于对企业对项目的管理和进度的控制。现在机械制造企业的企业活动都是以项目的形式来进行的。而机械制造企业所涉及到的项目,其规模越来越大,涉及到的专业也愈加广泛与多样,其内部关系也愈加错综复杂,所要调动的资源数量与种类相对以往也更加巨大和复杂。因此提高项目管理水平对于每一个制造企业都是至关重要。本文根据机械制造企业项目的特点,针对制造业在项目管理上存在的问题:实施过程中中远期目标不明确,任务计划规划不清晰;产品开发仅凭项目经理的经验进行管理,缺乏流程管理,各部门各自为政,无法统一协调;在项目进度的监控与管理上缺乏预见性,计划的执行常常流于形式,无法起到应有的作用;项目经理缺乏必要的项目管理知识和技能,无法解决项目突发情况等,进行了深入研究。提出了一个合理有效的解决方案,主要内容有以下几点:首先,针对项目进度计划的制定,引入了关键链技术以及缓冲机制的思想,对项目任务的工期进行科学的估算,并且对任务的缓冲区进行统一管理分配,避免了传统方法制定项目工期时出现的水分。其次,对于项目进度信息的获取和反馈,提出了基于文档驱动的项目进度控制模型,将项目任务进度信息进行量化计算,实现了项目进度信息的自动、实时、准确的反馈,以便项目参与人员对项目进度信息的获取。最后,针对以往项目进度预警困难,警报信息不准确,反馈速度不及时等问题,提出了多级项目进度预警机制,多角度的对项目进度信息进行分析预警,使项目参与者全面掌控项目的实施。根据以上的研究结果,本论文进行了具体的实践验证,将提出的相关模型、算法以及技术融入到基于PDM的项目进度管理系统的研究和开发中来。通过在企业里的实际应用检测,该系统取得了良好的使用效果,验证了上述思想和技术的合理性和科学性。
[Abstract]:With the development of science and technology, market competition is becoming more and more intense. In order to ensure a place in the market for survival and development, mechanical manufacturing enterprises must speed up the upgrading of products. Improve the efficiency of product innovation and R & D. How to improve the R & D ability and work efficiency of enterprises, the key is to control the project management and progress. At present, the enterprise activities of machinery manufacturing enterprises are carried out in the form of projects. The projects involved in the machinery manufacturing enterprises are becoming larger and larger, involving more extensive and diverse specialties, more intricate internal relations, and the amount and types of resources to be mobilized are more huge and complex than before. Therefore, it is very important for every manufacturing enterprise to improve the level of project management. According to the characteristics of the project in the mechanical manufacturing enterprise, this paper aims at the problems existing in the project management of the manufacturing industry: the long-term goal is not clear, the task plan is not clear, the product development is managed only by the experience of the project manager. Lack of process management, the departments can not be unified and coordinated, in the monitoring and management of project progress lack of foresight, the implementation of the plan is often a mere formality, can not play its due role; The project manager lacks the necessary knowledge and skills of project management, and can not solve the unexpected situation of the project. A reasonable and effective solution is proposed. The main contents are as follows: firstly, the key chain technology and buffer mechanism are introduced to estimate the duration of the project. And the buffer of the task is managed and allocated uniformly to avoid the moisture that occurs when the traditional method is used to make the project duration. Secondly, for obtaining and feedback of project progress information, a documentation-driven project schedule control model is proposed. The project task schedule information is quantified to realize the automatic, real-time and accurate feedback of project progress information. For project participants to obtain information on the progress of the project. Finally, aiming at the problems such as difficulty of project progress warning, inaccurate warning information and untimely feedback speed, a multi-level project progress warning mechanism is put forward, and the project progress information is analyzed and forewarned from many angles. Enable the project participants to take full control of the implementation of the project. According to the above research results, this paper has carried on the concrete practice verification, will put forward the related model, the algorithm and the technology into the research and the development of the project schedule management system based on PDM. Through the practical application in the enterprise, the system has achieved good application effect, and verified the rationality and scientific nature of the thought and technology mentioned above.
