Human-Computer Simulation and Analysis of Construction Operations

摘要

The first phase of a long-term research and development plan to provide the construction industry with analytical management techniques is reported. Described is a computer-based system which simulates operations such as earth-moving, tilt-up construction, concrete placing, and high-rise building erection. The primary goal is to make this system and its components into everyday working tools for estimators, project engineers, superintendents, and others charged with the planning and management of construction operations. A conceptual introduction to the system is provided, along with brief descriptions of each of four main supporting areas of research--time lapse photography for data acquisition and analysis; network-based stochastic simulation of construction operations; computer graphics; and technical and human factors in designing interactive man-computer systems. The report reviews work accomplished; explains the current level of implementation of the system; and highlights the key steps needed to film an operation, extract and process data, build a simulation model of the operation, and interactively analyze and improve the filmed process. Limitations of the system in its present form are summarized and recommendations for further research are suggested.
