An approximate policy for a dual-sourcing inventory model with positive lead times and binomial yield

This paper studies the inventory system of a retailer who orders his products from two supply sources, a local one that is responsive and reliable, but expensive, and a global one that is low-cost but less reliable. The deliveries from the global source only partially satisfy the quality requirements.Wemodel this situationwith a dual-sourcing inventory model with positive lead times and random ...

Delivery Cost Approximations for Inventory Routing Problems in a Rolling Horizon Framework

The inventory routing problem considered in this paper is concerned with the repeated distribution of a commodity, such as heating oil, over a long period of time to a large number of customers. The problem involves a central depot as well as various satellite facilities which the drivers can visit during their shift to refill their vehicles. The customers maintain a local inventory of the comm...

A Route Improvement Algorithm for the Vehicle Routing Problem with Time Dependent Travel Times

In urban areas, congestion creates a substantial variation in travel speeds during peak morning and evening hours. This research presents a new solution approach, an iterative route construction and improvement algorithm (IRCI), for the time dependent vehicle routing problem (TDVRP) with hard or soft time windows. Improvements are obtained at a route level; hence the proposed approach does not ...
