In brief Calculating carbon emissions for less than truckload (LTL) is more challenging than for other modes of transportation. Each LTL truck combines a wide mix of freight from many shippers, with varying origin-destination pairs. Without visibility to the details about individual shipments on that truck, accurate carbon emission estimates at the shipment level can be difficult to obtain. Gra...

We study performance improvement in multi-echelon, closed loop spare part supply chains using operational interventions based on real-time status information. Our objective is to minimize the total cost relevant costs, consisting of intervention costs and backorder costs. In this paper, we focus proactive interventions, aiming avoid stockouts. assume that all reactive are fixed. Proactive inclu...

Background: Finding trends in freight transportation activities enables businesses and policy makers to build an understanding of patterns their impact on logistics planning when making investments a region’s infrastructure intermodal transport system. To the best our knowledge, there is limited literature data-driven analysis about mode choices influencing factors Atlantic Canada. Methods: In ...

This paper aims to compare a two-echelon and a single-echelon distribution system. A mathematical model for the Single-Echelon Capacitated Vehicle Routing Problem (SE-CVRP) is proposed. This SE-CVRP is the counterpart of Two-Echelon Capacitated Vehicle Routing Problem (2E-CVRP) introduced in the authors’ previous work. The proposed mathematical model is Mixed-Integer Non-Linear Programming (MIN...

 Abstract: The shipments of hazardous materials (HAZMATs) induce various risks to the road network. Today, one of the major considerations of transportation system managers is HAZMATs shipments, due to the increasing demand of these goods (because it is more used in industry, agriculture, medicine, etc.), and the rising number of incidents that are associated to hazardous materials. This paper ...

This guidance represents FDA’s current thinking on sampling and testing yellow corn and dry-milled yellow corn shipments for Cry9C protein residues. It does not create or confer any rights for or on any person and does not operate to bind FDA or the public. 21 CFR 10.115(d). The agency is now issuing final guidance for implementation in accordance with FDA’s regulation on administrative practic...

We study robust network design problems for hazardous materials transportation considering risk uncertainty. Risk uncertainty is considered in two ways: (1) uncertainty on each link for each shipment, and (2) uncertainty on each link across all shipments. We extend an existing heuristic framework to solve these two robust network design problems and propose a Lagrangian relaxation heuristic to ...
