Abstract

In humanitarian fleet management, the performance of purchase, assignment, and sales decisions is determined by dynamic interactions between the fleet composition, the time-varying and uncertain demands on the fleet, and the depreciation of the vehicles as they are exploited. We propose to evaluate purchase, assignment, and sales policies in a holistic simulation environment that directly models heterogeneous vehicle attributes and tracks their evolution over time. Using data from a large international humanitarian organization (LIHO), the simulator can identify the rationale behind seemingly ad-hoc decisions by field managers at LIHO. For instance, by selling vehicles later than LIHO recommends, managers are actually reducing their costs; similarly, managers decline to switch vehicles between mission types because the benefits to the operational cost turn out to be marginal at best.
