Abstract

After an emergency outbreak, it is extremely hard to obtain reasonable solutions for emergency decisions facing information asymmetries. This paper aimed at the problem of simultaneous deciding locations of emergency resource centers and the delivery paths in a scenario with uncertain demand. Firstly, the paper introduced the triangular fuzzy number to depict the fuzzy demand and proposed an emergency resource center location-routing model based on the fuzzy demand. Then the algorithm formed the high-level strategy by defining the states, actions, and rewards in Q-learning. Finally, the paper presented a Q-learning based hyper-heuristic by encapsulating the low-level heuristic operators with a new architecture. The numerical experiments verify the effectiveness of the algorithm, meanwhile showing the feasibility of the model and algorithm in practical applications by a case study.
