Abstract
In humanitarian logistics (HL), prioritizing of relief item distribution under limited transportation capacity is an important and practical problem that relief organizations face. The priority not only depends on the dynamic demand urgency, but also on the different equity concerns between distribution managers (high-level) and point of distribution (POD) managers (low-level). In this paper, through field investigations, we adopt deprivation cost to capture the dynamic priority among different relief items like drinking water or tents, and envy to represent the equity perceptions of victims, based on which we study a bi-level distribution-allocation problem to answer the following research questions: (1) Which kind of relief item at which time point should be distributed in priority with limited transportation capacity? (2) What’s the impact on distribution strategy when there are misalignments between bi-level decision-makers? Should the distribution managers take envy of victims into account? We build a non-linear model which minimizes the sum of deprivation cost of different relief items and the possible penalty caused by envy. A case study based on real-world data is conducted to show the feasibility of our method and model. Summarizing, this paper presents an original approach to incorporate the dynamic priority of relief item distribution in a bi-level system, taking a ‘people-centered’ perspective.
