Abstract

Highlights: This paper proposed a location-routing problem for biomass supply chains. A novel mixed integer programming model is established for the location-routing problem. A hierarchical heuristic algorithm based on Tabu Search is developed. Comprehensive computational examples are conducted to verify the proposed approach. Abstract: Facility location and vehicle routing are two critical decision problems in the design of biomass supply chains. Different from previous studies considering these two problems separately, this paper integrates the facility location and the vehicle routing problems for biomass supply chains into a single one, namely the location-routing problem for biomass supply chains (LRP-BSCs). A mixed integer programming model is established for the LRP-BSCs, which can achieve the optimal decisions for small-scale instances. Due to the intrinsic computational complexity of the LRP-BSCs, a hierarchical heuristic algorithm based on Tabu Search is developed for the problem solution. Comprehensive computational examples verify that the proposed approach is effective and efficient.
