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...

One of the simplest methods for short-term handling and storage of fish is the refrigeration in combination with dip treatments. This study was conducted to determine the effect of pre-storage α-tocopherol acetate dipping treatments on lipid stability of refrigerated rainbow trout fillets. Trout fillets were dipped in α-tocopherol acetate solutions (200 and 500 mg kg-1 flesh) and subsequently s...

To assess the effects of pre-analytical handling (storage time and temperature) on selected hematological parameters, whole blood samples were collected in EDTA coated tubes from each of 30 clinically normal male adult beagle dogs. Each sample was separated in 2 aliquots, of which one was stored in ambient temperature (25 ˚C) and the other one was refrigerated (2 to 4 ˚C). Complete blood counts...

Introduction In recent years there have been major changes in the composition of cargo to the point where, in Europe, semi-finished products (e.g. car parts) and finished goods represent the greatest transport demand. This type of cargo is typically of lower density and higher value (LDHV) than previous goods and requires faster and more reliable transportation. Currently, LDHV goods are predom...

Freight and passenger transport are two main functions of the infrastructure and transportation networks in each country. It is required to efficiently utilize the transportation infrastructures to increase transportation-related performance measures. In this study, data envelopment analysis (DEA) model is used to evaluate performance of the Iranian provinces from the freight and passenger tran...

The paper discusses requirements for freight modelling and presents specific approaches concerning freight surveys, demand and network modelling, rail freight optimisation and freight assignment including: • Surveying methods for collecting road based demand data. • WIVER/VISEVA: a demand modelling system for urban and regional commercial transport. • SPIN: a multimodal network model for interm...

This study aims to determine the process of handling imported pesticides in red lane by freight forwarders. The used a qualitative approach, with subject employees import operations and customer service PT Link Pasipik Indonusa Surabaya Branch obtained purposive sampling. Data were using interviews, observation documentation, which then analyzed descriptively qualitatively. result this research...

While largely due to conditions outside their control, the configuration and setting of current intermodal rail terminals contribute to congestion and increased freight handling volumes that have resulted in additional transportation costs for shippers and carriers. Although a substantial body of research has focused on improving the efficiency of port operations and multi-modal freight shipmen...

Abstract The Red Squirrel ammonia field experiments were conducted at the DNV Spadeadam site in UK 2022. Field test data currently exists for high‐pressure (ambient temperature) two‐phase releases of from Desert Tortoise (1983) and FLADIS (1996) experiments. No tests have ever been done cold (refrigerated) liquid spills on dry land or into water. handling liquified ammonia, during storage/proce...
