|Abstract:||This thesis proposes a generic methodology for designing logistics networks integrating reverse logistics into a current supply chain. Such networks involve the recovery of unused products from the end-users, and their processing and redistribution toward new users. According to their state, recovered products may be repaired, disassembled for the recovery of parts and disposed. Reusable products resulting from processing are indicated as valorised products. They represent an economical supply source, which meets a lower quality standard compared to new products. The methodology aims at supporting decisions on location and definition of mission of business units. They relate to the reverse logistics portion of a network, particularly as regards recovery and processing centres as well as warehouses for valorised products, while considering the current operating context of a supply chain. Decisions also tackle the strategic proportion of products to be directed toward processing alternatives according to the product recovery possibilities and network conditions, which relate to the recovery and demand volumes with respect to the capacity constraints and operating costs. The network is evaluated in a stochastic environment with regard to the demand, recovery and processing volumes, according to recovered product states. Modeling approaches are proposed to define key parameters for the related mathematical programming model. A heuristics based on the Sample Average Approximation (SAA) method, involving the Monte Carlo sampling methods, is proposed to solve the stochastic model. The methodology is validated with the wheelchair allocation, maintenance, recovery, processing and redistribution context in the Province of Quebec, Canada, governed and managed by the Quebec Health Insurance Board (Régie de l’assurance maladie du Québec - RAMQ).|
