Construction Decision Support System for Delay Analysis

9522629开发了用于个人计算机的延误分析施工决策支持系统(DAS-延误分析系统)，以集成现有的项目控制系统和进度计划，增加了确定延误的可能原因并提出防止进一步延误的替代行动方案的能力。数据分析系统旨在证明为获取知识提供一个互动环境以改进项目控制和分析过程的重要性。互动系统的开发增强了信息处理和决策能力。监测项目进度的能力，以及在个人计算机的帮助下确定可能的延误原因和提出纠正措施的能力，提供了对项目业绩的一致评估。DAS第二阶段研究的目标是包括与合同和项目参数有关的额外知识库，如不同类型的项目、不同地点的项目和不同类型的公司，以增加其对建筑业不同部分的有用性。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。这一分析的结果将用于改进DA系统的子模型。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，其中将包含与国际施工有关的延误知识。还将进行研究，以便在建设项目完成后解决问题。***

9522629 Yates 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 in to resolution upon completion of construction projects. ***
