Representation of work spaces using a parametric model to support time-space conflicts analysis (A case study for time-space conflict analysis for the International Linear Collider project)

摘要

Time-space conflict analysis has been used to improve work schedule in the construction industry. This paper presents a case study where we test the validity of 4D-based timespace conflict analysis for improving the installation schedule of the system components in the International Linear Collider (ILC) project. Conducting time-space conflict analysis for the installation work requires representing work spaces necessary to install the components. In this paper, we explore the most suitable methods to represent the work spaces to support the time-space conflict analysis. Throughout the exploration, we apply three different methods (i.e., a method using isotropic “tolerance” concept, a method using traditional 3D solid modeling, a method using parametric modeling) to represent the work spaces. From the application of these three different methods, we compare and discuss the strengths and weaknesses each of the three methods.
