37 Utilization Estimation Factors This chapter introduces the utilization measurement metrics and describes the factors that are important to the utilization estimation of fleet equipment. 4.1 Utilization Measurement Metrics Annual mileage, annual engine hours, usage over the last 12 months, and frequency of use are the utilization metrics most widely used by state DOTs.
|
From page 38... ...
38 The UPM software estimates either average annual mileage, annual engine hours, or frequency of usage for each equipment type and class at a region-level based on the data provided by the user for the equipment types and classes listed in Table 1. The factors contributing to region-level utilization and their definitions are listed in Table 2.

41 Equipment Utilization Management Framework Optimal fleet size and utilization level in a region minimize the total fleet management costs while meeting available budget, maximum utilization thresholds, and demand constraints. A mathematical program is required to account for these constraints, find the optimal fleet size and utilization level in each region, and determine how to achieve these optimal sizes and levels by purchasing, salvaging, and relocating equipment assets while minimizing total fleet management costs.
|
From page 42... ...
42 a weighted average (based on the fleet size in each region) is calculated.

43 Equipment Utilization Management Process Figure 1 shows the general process for fleet UPM. This process heavily depends on equipment input data, and users need to provide accurate data regarding fleet equipment current utilization, costs, and other characteristics.
