Abstract

Earned Value Management (EVM) is the conventional method for controlling and monitoring construction projects. Schedule monitoring with EVM has a lower impact since it measures in budgetary terms. Earned Duration Method (EDM) was presented, which decouples schedule and cost aspects. The parameters in EDM monitors the health of the project schedule and gives the estimated completion date. EDM results are indeterministic, so the estimators require expertise in order to comprehend them. For this purpose, the present study proposes a new methodology entitled "Grey Earned Duration Management (GEDM)" by associating EDM and grey theory. From GEDM, estimators can get a clear idea about the degree of control measures to consider based on the project progress at a particular point in time. GEDM can precisely forecast the upper bound and lower bound of the estimated duration at completion for every tracking point. GEDM significantly enhances the results of EDM by providing a range of the estimated parameter. This paper also presents a case study to distinguish the EDM and GEDM.
灰色挣时管理:一种新的进度监控方法
挣值管理(EVM)是对建设项目进行控制和监控的常用方法。使用EVM进行进度监控的影响较小,因为它是按预算进行度量的。提出了挣时程法(EDM),将进度和成本解耦。EDM中的参数监视项目进度的运行状况,并给出估计的完成日期。EDM结果是不确定的,因此评估人员需要专业知识才能理解它们。为此,本研究通过将EDM和灰色理论联系起来,提出了一种名为“灰色赚取时间管理(GEDM)”的新方法。从GEDM中,评估人员可以清楚地了解基于特定时间点上的项目进度所考虑的控制措施的程度。GEDM可以精确地预测每一个跟踪点完成时估计持续时间的上界和下界。GEDM通过提供一个估计参数的范围,显著提高了电火花加工的结果。本文还介绍了一个区分EDM和GEDM的案例研究。

期刊介绍: The International Review of Civil Engineering (IRECE) is a peer-reviewed journal that publishes original theoretical papers, applied papers, review papers and case studies on all fields of civil engineering. The scope of the Journal encompasses, but is not restricted to the following areas: infrastructure engineering; transportation engineering; structural engineering (buildings innovative structures environmentally responsive structures bridges stadiums commercial and public buildings, transmission towers, television and telecommunication masts, cooling towers, plates and shells, suspension structures, smart structures, nuclear reactors, dams, pressure vessels, pipelines, tunnels and so on); earthquake, hazards, structural dynamics, risks and mitigation engineering; environmental engineering; structure-fluid-soil interaction; wind engineering; fire engineering; multi-scale analysis; constitutive modeling and experimental testing; construction materials; composite materials in engineering structures (use, theoretical analysis and fabrication techniques); novel computational modeling techniques; engineering economics. The Editorial policy is to maintain a reasonable balance between papers regarding different research areas so that the Journal will be useful to all interested scientific groups.
