Construction Decision Support System for Delay Analysis (DAS)

延迟分析的施工决策支持系统（DAS -延迟分析系统）用于个人计算机上的开发，以整合现有的项目控制系统和调度程序，通过增加的能力，确定可能的原因延误，并建议替代方案的行动，以防止进一步的延误。DAS的目的是证明提供一个互动的环境，以改善项目控制和分析过程中的知识获取的重要性。互动系统的开发提高了信息处理和决策能力。借助个人计算机监测项目进度、确定延误的可能原因和提出纠正行动的能力，可对项目业绩作出一致的评价。DAS研究第二阶段的目标是包括与合同和项目参数有关的其他知识库，例如不同类型的项目，不同的项目地点和不同类型的公司，以增加其对建筑业不同部门的有用性。收集的数据将使用假设检验进行分析，以确定不同参数和延迟类型之间是否存在相关性。该分析的结果将用于改进DA系统子模型。其他研究目标包括在国际延误领域进行研究，包括文化因素，并创建新的子模型，将包含与国际建设有关的延误知识。还将在建设项目完成后进行研究以解决问题。

The Construction Decision Support System for Delay Analysis (DAS - Delay Analysis System) for use on personal computers was developed to integrate existing project control systems and scheduling programs by adding the capability of determining possible causes for delays and suggesting alternative courses of action to prevent further delays. The DAS was designed to demonstrate the importance of providing an interactive environment for knowledge acquisition to improve project controls and analysis processes. The development of the interactive system enhances information processing and decision-making capabilities. The ability to monitor the progress of a project, and to determine possible causes of delays and suggest corrective actions with the aid of a personal computer provides consistent evaluation of project performance. The objective of the second phase of the DAS research is to include additional knowledge bases related to contract and project parameters such as different types of projects, different locations of projects, and different types of firms to increase its usefulness to the diverse segments of the construction industry. The data collected will be analyzed using hypothesis testing to determine whether there are correlations between the different parameters and types of delays. The results of this analysis will be used to refine the DA system submodels. Additional research objectives include conducting research in the area of international delays, including cultural factors, and creating new submodels that will contain knowledge on delays related to international construction. Research will also be conducted into resolution upon completion of construction projects.
