Determination of rational values of the parameters of the container depot

Today, due to the increase in rail freight traffic, there is a shortage of containers, and the issue of shortage of containers has not been resolved for a long time. This substantiates the practical relevance of the study of container depots in railway transport. Another task is the development of mathematical models of the interconnection of the parameters of the container depot. Currently, there are several different methods and methods for calculating and determining the parameters of container sites, the analysis of which is given in the article. However, there is a need to supplement, clarify and unify the existing methods for calculating all kinds of parameters for a container depot, which justifies the theoretical relevance of the study. Connections with which the purpose of the article is to develop a methodology for the reliable determination of the most rational values of the parameters of the container terminal, thereby improving and increasing the level of customer service in transport in general. Research methods are based on a systematic analysis and generalization of existing methods and methods for calculating the capacity of container depots. The results of the study are presented by the developed methodology for determining the capacity of warehouses on railway transport, which provides a more qualified calculation and selection of container depot parameters, as well as a decrease in erroneous design decisions and an increase in the reliability of projects for the development and improvement of railway transport and the transport network as a whole.

The application of semi-automated gantry cranes in empty container depots

<p>Purpose – The storage and supply of empty containers is a bottleneck in the global supply chain. In the wake of increasing containerisation and globalisation, improving efficiencies of processing within empty container depots can realise efficiencies. The overall objective of this research project is to propose an efficient and effective solution for reducing waste in an empty container depot using a crane. The issue of applying gantry cranes to empty container depots will cover both an operational and a strategic evaluation of the following research questions: 1) What are the potential solutions for a specific yard based on lean thinking, and which solution should be used within the constraints and contexts of this yard? 2) Who are the key stakeholders, and what are their stakes while implementing the solution in the yard to reduce waste? Design/methodology/approach – A review of the literature around empty container depots revealed that while lean operations have been applied to manufacturing, warehousing, and ports, it has not yet been applied to empty container depots. Whereas warehouses primarily deal with stock-holding and ports deal with quayside operations, empty container depots act as a conduit between consignors and consignees. In the vein of American Pragmatism, Design Science Research, and Strategy-as-Practice, this thesis shows that in the context of empty container depots a gantry crane is an artefact that can create efficiencies, reduce costs, as well as explore further effects on the organisation and its wider geo-political habitus. Case Study – A New Zealand company that handles roughly half a million TEUs per annum cooperated with this study. The study was conducted by analysing data from four working depots (Auckland, Tauranga, Napier) selected to illustrate variations in container volumes, types of flows (imports, exports, seasonality), and depot layouts. The current operations of these depots were analysed using lean operations, value stream mapping, and operations interwork centre flow graphs. Of the four sites identified, one (the Auckland OCP site) was shown to achieve the greatest results from a gantry crane. The results of the analysis were then used to develop a potential solution in which waste was identified and eliminated, primarily around excess handling and land utilisation. Findings – A key finding was that efficiency gains differ from site to site based on their unique demands and overall layouts. Furthermore, changes towards the current yard using gantry cranes need to be implemented incrementally based on continuous improvement. This is due to practical constraints around operations, culture change, cashflow management, the acquisition of capital, and broader market/stakeholder influences. Originality/value – The practical applications of this research case are scalable on a vast level. The effects of this research are explored in how the introduction of an artefact affects the organisation, its vision of itself, its strategies, and the broader supply chain in which this organisation operates. The results are further re-contextualisted in order to offer a holistic view of an artefact in its situated environment.</p>

Economic Justification for Development and Operationalization of Rail-Freight-Corridors Between Hub-Seaports and Inland Container Depots in Nigeria

The study provided economic justification for private sector investment in developing, revitalizing and making operable, the rail-freight-corridors between hub-seaports and inland container depots in Nigeria. It estimated the operator-benefits and profitability potentials of investment in each of the ten rail-freight-corridors consisting of existing but inoperable and proposed rail routes from the major seaports to the Inland container depots in different geopolitical regions of Nigeria. Secondary data on the import and export (cargo generation) capacities of each of the ICD regions to and from the respectively connected hub-seaport were obtained from the Nigerian ports authority statistical report covering a period of two years (2018 – 2019) based upon which the annual expected revenue earnings of the operators were estimated. The cost of investment was also obtained. Benefit-Cost-Ratio (BCR) and Net Present Value (NPV) were used to estimate the operator-benefits and profitability potentials of each rail route. It was found that six of the rail routes have BCR > 1; and NPV>0; implying higher operator-benefits over costs within the period while four of the rail-routes have BCR <1; and NPV <0; implying higher operator-costs over benefits.

MODEL OF THE OFF-DOCK DEPOT CONGESTION PROBLEM: VALIDATION THROUGH DELPHI TECHNIQUE

World trade has grown over the last two decades and has led to increasing demand for containers. As such, container transport by truck is growing either inside or outside the port terminal. This study aims to gain expert confirmation of the clarity and practicality of the 'congestion problem model in empty container depots' through the Delphi technique. This technique is carried out in two rounds by several experts who have knowledge and experience in container management. Overall, the Delphi analysis shows that the average value exceeds 75%, proving that the model of the congestion problem chain has been approved by the panel of experts. Finally, all panel of experts has the same view regarding the development of this model that it is able to provide a clear understanding of the factors involved in congestion problems outside of the port. Therefore, this model can also serve as a guideline for stakeholders to reduce delays especially during the operation of empty container pick-up and drop-off.

DESIGN RELAYOUT COMPANY WITH WEIGHTED DISTANCE METHOD FOR MINIMIZE OF TRAVEL TIME

PT IJS is a company engaged in logistics services in the Perak area of ​​Surabaya. PT IJS was founded in 1984 when the need for container depots was urgently needed around the Tanjung Tanjung port area to unravel the shipping queues and shorten licensing. One of the services provided by PT IJS is bounded warehouse rental services. Bounded warehouse owned by PT IJS is currently not able to provide maximum service because there are still many late deliveries which do not result in the sending of goods to the port and there is a closing time that is detrimental to the customer. The length of the delivery process is due to several factors, one of which is a less effective company layout. Travel time is the time required for a vehicle to carry out goods loading activities at PT. IJS from arrival to exit company. Based on travel time calculations when using the initial layout, the travel time value of T = 2002 seconds. The weighted-distance method is a mathematical model used to evaluate the layout based on proximity factors. The design of the relayout design using the weighted-distance method produces alternative layouts that produce shorter travel time calculations, alternative layout with T = 1849 seconds.

Container depot location problem in the frame of the Polish part of the New Silk Road

The Chinese project One Belt One Road, in Europe often referred to as the New Silk Road, triggers infrastructural investments enabling seamless transportation of goods on the Eurasian route. Since most of these goods are transported in containers, the optimal location of inland container depots, where containers wait for future repositioning after they had been emptied at the importers, is an interesting problem. In this paper conditions determining the optimal location of inland container depots in the Polish part of the NSR are analysed. They include proximity of container transhipment terminals located on the Polish stretch of the NSR, structure of highway network enabling distribution of containers by trucks to other destinations, as well as green aspects mainly referring to avoidance of city congestion caused by trucks transporting containers.
