Concurrent Locomotive Assignment and Freight Train Scheduling
The locomotive assignment and the freight train scheduling are important problems in railway transportation. Freight cars are coupled to form a freight rake. The freight rake becomes a train when a locomotive is coupled to it. The locomotive assignment problem assigns locomotives to a set of freight rakes in a way that, with minimum locomotive deadheading time, rake coupling delay and locomotiv...
متن کاملPeriodic Review Inventory Management with Contingent Use of Two Freight Modes with Fixed Costs
We study a stochastic inventory model of a firm, that sources the product from a make-to-order manufacturer, and can ship orders by a combination of two freight modes. The two freight modes differ in lead-times, and each has a fixed and a quantity proportional cost for each use. The ordering decisions are made periodically; however, the inventory holding and back-order penalty costs are incurre...

In this article we estimate external costs for four representative types of freight trains. For each type of freight train, we estimate three general types of external costs and compare them with the private costs experienced by railroad companies. The general types of external costs include: accidents (fatalities, injuries, and property damage); emissions (air pollution and greenhouse gases); ...

negative impact of delays on customer service level by keeping redundant inventory or safety stock. Although safety stock protects companies from disruptions or delays, this comes at a cost because higher inventory levels tie up working capital and increase inventory management costs, such as warehousing and damage rates. In addition, the higher inventory level increases the risks associated wi...
متن کاملContinuous Review Inventory Model with Dynamic Choice of Two Freight Modes with Fixed Costs
We analyze a continuous review stochastic inventory model in which orders placed with a make-to-order manufacturer can be shipped via two alternative freight modes differing in lead-time and costs. The costs of placing an order and using each freight mode exhibit economies of scale. We derive an optimal policy for utilizing the two freight modes for shipping each order. This freight mode decisi...
