Abstract
In this work, we present two MILP models of collection-disassembly problem where a fleet of vehicles is deployed to collect End-of-Life (EOL) products from collection centers and transport them to a dedicated disassembly facility. The problem studied integrates two NP hard problems, Inventory Routing Problem and Dynamical Lot-Sizing Problem, within the context of reverse supply chain. For each model, a multi-level product structure is considered where each item of the product to be disassembled is interconnected and yields different quantities obtained from the disassembly process. The first model covers the periodic decisions involving the vehicle routes, the quantity of EOL products to collect from each collection center, the quantity of each item to disassemble, the inventory level of each component, and the quantity of backlog for each item. In the second model, a facility location-based formulation is developed to provide a better lower bound of the problem.
