A Simulation Approach for Evaluating Urban Snow and Ice Removal Planning and Operations

摘要

This paper presents a graphical discrete-event simulation (DES) model for the planning and operation of snow and ice removal in urban areas. The modeling is developed based on the scenarios previously described in Alprin (1975) using a new version of stochastic Petri nets (SPN) called Abridged Petri Nets (APN). The importance of flexible vehicle assignment to different snow removal routes is demonstrated. The model includes constraints with respect to limited vehicle and infrastructure resources as well as allowing for the possibility of mid-mission vehicle failures.
