Abstract: With the continuous development of the economy and the rapid advancement of urbanization, the amount of refuse produced nationwide is rapidly increasing, and the cost for refuse processing is in turn on the rise, with refuse collection occupying an increasing proportion of it. A complex refuse collection problem is investigated, i.e., the multi-station refuse collection problem (MSRCP). The MSRCP is mapped to the multi-depot vehicle routing problem (MDVRP), and a model for MSRCP with the goal of minimum vehicle transportation cost is established. According to the characteristics of MSRCP, an approach based on Cooperative Co-evolutionary (CC) as external framework is designed for the problem. Firstly, the improved clustering algorithm is used to assign each collection point to the appropriate station. Then, a hybrid genetic algorithm (HGA) is designed for the vehicle routing problem (VRP) with the stations as the depots and MSRCP being divided into some VRPs. Finally, the refuse collection in Daguan District of Anqing City was taken as an example to verify the model and its algorithm, The results show that the proposed algorithm is effective in reducing transportation cost of complex refuse collection problems.
