| dc.description.abstract | The year-end road maintenance evaluation is an important annual assessment conducted by the Highway Bureau. Its purpose is to review the effectiveness and performance of maintenance efforts by various engineering sections over the year. The evaluation scores directly impact the bonuses of section personnel, and those who achieve excellent rankings receive additional rewards. Consequently, this evaluation is of utmost importance to each engineering section. The scheduling of road maintenance patrols is based on the duties of each staff member, the requirements of the patrol operations, and their familiarity with the provincial roads. Although the current scheduling model can generally handle the year-end evaluations, there are still areas for improvement. By constructing the scheduling constraints into a mathematical model to obtain the optimal schedule, patrol operations can be completed more quickly and systematically.
This study takes an engineering section of the Highway Bureau as a case example, aiming to determine the optimal evaluation patrol schedule for the section’s engineering personnel. Based on the schedules and patrol areas of each engineer, we establish a mathematical model and use Lingo18 software to output the results to Excel, obtaining the optimal number of patrol days. Subsequently, through sensitivity analysis, we examine the impact of changes in personnel, vehicles, and familiarity with tasks on the schedule optimization. This analysis provides a reference for section supervisors in future scheduling, aiming to save patrol time, improve work efficiency, and achieve the fastest possible completion of patrol assignments. | en_US |
