A Dedicated Subnetwork (DSN) refers to a subset of lanes with associated loads in a shipper’s transportation network, for which a fleet of resources – trucks, drivers, and other equipment – is exclusively assigned to carry out all shipping requirements. The resources assigned to a DSN are...

This paper analyzes the tradeoff between (demand) substitution costs and (production) changeover costs in a discrete-time production-inventory setting using a two-product dynamic lot-sizing model with changeover, inventory carrying, and substitution costs. We first show that the problem is...

We study zero-inventory production-distribution systems under pool-point delivery. The zero-inventory production and distribution paradigm is supported in a variety of industries in which a product cannot be inventoried because of its short shelf life. The advantages of pool-point (or...

We consider the problem of scheduling operations in bufferless robotic cells that produce identical parts using either single-gripper or dual-gripper robots. The objective is to find a cyclic sequence of robot moves that minimizes the long-run average time to produce a part or, equivalently,...

New currency recirculation guidelines implemented by the Federal Reserve System (Fed) of the United States are intended to reduce the overuse of its currency processing services by depository institutions (banks). These changes are expected to have a significant impact on operating policies at...

Line extensions – variants of existing products with new appearances, functions, or forms – constitute a significant fraction of products launched each year. While line extensions typically share components with existing products and, therefore, require lower development costs (as compared...

The Healthcare Information Exchanges (HIEs) facilitate the electronic transfer of health information among healthcare organizations. Several studies have shown that the HIEs have potential of saving billions of dollars per year and significantly improving healthcare delivery. In spite of that,...

The goals of the Guaranteed Support Price (GSP) scheme, adopted by several developing countries to support their farmers and the underprivileged population, are threefold: (a) as a supply-side incentive, to ensure high output from the farmers, (b) as a demand-side provisioning tool, to subsidize...

"Cloud Kitchens" are delivery-only facilities that house multiple restaurants. Food-delivery platforms operate such kitchens to exploit two advantages: (i) Location advantage, arising due to a cloud-kitchen's central location this enables lower delivery times to customers. (ii) Consolidation...

Problem definition: Revenue management in railways distinguishes itself from that in traditional sectors such as airline, hotel, and fashion retail, in several important ways: (i) Capacity is substantially more flexible, in the sense that changes to the capacity of a train can often be made...
