Description

The instance title presents the number of potential sites (n), the number of periods (h), the number of mobile collection sites (m), the number of shuttles (u), and the number of hospitals (v). Each instance presents the following: First, general information: n: number of potential sites m: number of mobile collection sites u: number of shuttles Q: capacity of the mobile collection sites [whole-blood units] h: number of periods of the planning horizon v: number of hospitals tMax: arrival time limit [units of time] Second, the demand for platelets (PLTs) units in each period t and each hospital z. Third, the demand for red-blood-cells (RBCs) units in each period t and each hospital z. Fourth, parameters related to each node i, where the first and last nodes correspond to the blood center and the others to the potential sites: x and y: coordinates s: service time [units of time] p: total donation level or profit [whole-blood units] e: opening time of activities [units of time] l: closing time of activities [units of time] Finally, the travel times between each pair of nodes
