Incorporating weather factors into construction mobility simulation.

摘要

The prediction of construction equipment mobility in winter is important for both cost and time schedule control. Unfortunately, this prediction is subject to the effects of several factors, which leads to an uncertain result. Among these factors, the effects of winter weather impact mobility the greatest. This thesis presents a mathematical algorithm to address the significant weather factor of snow accumulation and its effect upon the speed of the construction hauling equipment using a regression approach. The thesis also discusses other weather factors that impact mobility. A mobility model considering the effect of weather parameters is developed. This mobility model is applied to earthmoving construction simulation in order to analyze the extent to which cold weather affects project duration. The methodology models the occurrence of factors of uncertainty, quantifies their impact upon mobility, and calculates project duration based upon generated weather conditions. This model provides a better tool for scheduling purposes.
