We analyze the characteristics of the logistics systems including both direct and reverse flows, their activities and structure. We address the strategic planning problem of such systems and propose a facility location model as an extension of the simple plant location problem while taking into account the specific constraints related to reverse flows of directly reusable items. For solving this model,...
Reverse logistics is concerned with the return flows of products or equipment back from the consumer to the logistics network for reuse, recovery or recycling for environmental, economic or customer service reasons. In this paper, we review applications, case studies, models and techniques proposed for the design, planning and optimization of reverse logistics systems. We consider both cases of separate...
This paper discusses the problem of designing a logistic network for Less Than Truckload (LTL) shipments of freight transport providers. These companies have to collect products from many origins (suppliers) and ship them to many destinations (clients) through multi-stop routes and consolidate flows into hubs to achieve economies of scale. This problem is known as the Hub Location Routing Problem...
This paper presents a new tactical optimization problem for non-hazardous waste and end-life product supply chain. Waste transport and recycling become crucial in our modern society, with a huge environmental and economic impact for industrials and communities. Operations on products during transport such as grinding or sorting allows companies to densify transports and reduce the overall supply cost...
Tactical planning consists of developing production plans to fulfill client demands with a minimal logistic cost. However, plans generated by classical models for tactical planning do not consider a minimum financial need in terms of Working Capital Requirements (WCR) to maintain the activities related to the operating cycle. In this paper, we introduce a first link between tactical planning and the...
This paper presents a two-phase method to solve a routing and scheduling problem that arises in public works. In this problem, the quantity of demands generally exceeds the capacity of a truck. As a result, demands have to be split into full truckloads, taking into account the various capacities in the heterogeneous fleet of vehicles that perform the transportation. Full truckload routes have to be...
