A waste collection problem with service type option

• A hybrid waste collection system is modeled as an extended periodic location routing problem. New subtour elimination constraints for problems with intermediate facilities are introduced. Factors influencing the service type decision (pickup or bring system) presented. The developed ALNS provides good results also introduction of a pure system. Efficient solid management one most relevant issues urban communities. With regard to household collection, there two approaches in practice: when collecting via door-to-door system, vehicles drive down all streets empty garbage cans on curb. Using accumulated at central sites larger capacity. While residents do have travel additional distance dispose their these sites, can reduce be covered by because they no longer streets. To combine advantages both systems, this article corresponding problem option (WCPSTO) new variant and adaptive large neighborhood search-based solution approach proposed. This not only solves newly presented problem, but outperforms algorithm related seen literature, which special case WCPSTO.
