Abstract
Railroad transportation offers significant economic advantages over other modes of transportation, including low transportation costs per unit, the ability to move large amounts of goods faster and cheaper, efficient use of energy, and a relatively well-developed rail network. Since the deregulation of rail transportation, its market share has declined and freight transport demand has grown, resulting in unprecedented competition. Significantly increasing the efficiency and competitiveness of rail services is a pressing necessity.
Freight transportation is defined by customer requirements, resource classes, and network performance. A freight rail transportation system is made up of a variety of resource categories, including, but not limited to, wagons, locomotives, personnel, infrastructure, and management systems, to name a few. The overall operational efficiency of the rail system is influenced by how well these resources are utilised, and how efficiently they are used.
The previous studies suggest that the wagon distribution process of the case company has been a significant challenge in achieving its business and customer set goals. Reviewing how optimisation strategies can enhance railway planning and execution tools to improve operational efficiencies in the Natal corridor is the main goal of the study. To answer the research question and gain a thorough knowledge of the activities of the case study company, this investigation made use of statistical data approaches and a large body of literature. For the company under study, a model that simply generates distribution plans would greatly enhance the planning process.
The results and data from the case company's operations indicate that their planning procedures are theoretical rather than practical. Poor wagon distribution causes shortages, which leads to dissatisfied customers, lost business, and a deteriorating case company reputation. Second, having an excessively large fleet increases fleet mileage and the capital cost of wagons. Availability, dependability, and management of resources
are crucial to the success of the strategy. The case company should prioritise developing better plans that are executable while still acknowledging operational constraints.
