Abstract

This paper presents a simulation model by which a mowing operation is analyzed on a day-to-day basis. Included is the effect of rainfall-speed distributions for tractor-mower production as related to terrain features; hourly cost distributions for tractors, mowers, and service trucks; and time distributions for nonproduction activities that occur during the daily mowing operation. The speed and time measurements were observed on 169 acres of a 10.6-mile section of i-95 in the new castle maintenance district in delaware. The simulation model is described in the general purpose simulation system language. Output showing the simulated variation in total project times and costs for 20 observations of various amounts of assigned mowing area are shown. The model provides a tool by which the highway maintenance engineer can evaluate short- and long-range planning decisions that involve a series of highly variable time-consuming activities. Suggestions of other highway maintenance operations to which the model can be applied are presented.
