Abstract:It has been determined that the greatest risk of an error in determining the technical condition of the axle box unit in the so-called "zone of uncertainty" is in the impossibility of unambiguously assessing its technical condition. To solve this problem, a model is proposed in the form of an n-dimensional radius vector, which has a direction towards an increase in the probability of failure and a deterioration in its parameters' values. Such a model for determining the axle box unit's pre-failure condition wi… Show more
“…The railway capacity concept is a fundamental pillar within the realm of railway transportation. Previous studies have underscored that railway capacity is primarily influenced by factors such as train frequencies, timetables, rolling stock capacities, running times, and velocities [10]. Capacity evaluation strategies can be grouped into three main categories: analytical, optimization, and simulation.…”
To enhance railway utilization for freight transportation, it is crucial to integrate railroads with industrial zones and ports. This is particularly important for the central line railroad of North Java, which is located near numerous ports and industrial zones in East Java. A comprehensive analysis of railway capacity is necessary to ensure smooth train traffic flow. This study uses Indonesian methodology equations and a linear programming approach to assess the feasibility of adding more trains and establishing suitable headways. The case studies focus on train insertions from potential stations connected to ports in both westward and eastward directions. The train timetables of PT KAI (Indonesia’s Railway Company) as a train operator for 2019 and 2021 serve as the basis for this analysis. The analysis reveals that in 2019, it is possible to introduce 11 trains per day from Duduk Station heading west and 14 trains per day from Duduk Station heading east. Looking at the 2021 timetable, the analysis suggests the potential introduction of 12 trains per day heading west and 18 trains per day heading east from Duduk Station. These findings provide valuable insights for developing effective strategies to ensure efficient and seamless freight transportation by rail in Indonesia. This analysis highlights the potential for increasing train frequency and capacity, which can contribute to the overall development and growth of the railway sector in Indonesia.
