Opis:
In this paper we analyse several ways to compute the weights from the Regularized Han (RH) algorithm, the regularized version of Han’s algorithm for approximating the least squares solutions of inconsistent (incompatible) systems of linear inequalities. We tested our approaches on a classical transportation problem, aiming to provide a cost optimized solution to real world transportation problems, which often are unbalanced and inconsistent.

Opis:
Traversing the river Seine in Paris is challenging for inland vessels due to the density and diversity of local traffic that is encountered in a confined environment. The waterway authority, Voies navigables de France (VNF), commissioned a study to assess the relevance of the current regulations when vessels of varying types cross Paris. A first simulation study showed that regulations based on length only may be too restrictive for ships with smaller beams [1]. This paper presents additional simulations executed on a full mission bridge simulator with ships of reduced beam. The main bottlenecks happen at different locations depending on the ship’s beam and ships with smaller beam can sail at higher water levels than the ships considered in the first study. The maximum water levels for which safe passage is possible were determined for each ship. Finally, recommendations have been formulated, which were then discussed with VNF and stakeholders.

Opis:
The simulation as a tool for the design of port and terminals has emerged as an answer for the demand to enhance the quality and reliability of the project results. Very high costs of the project solution implementation and practically total lack of liquidity of transport infrastructure objects always induced the immense commercial risks in the terminal business. Lately these risks have multiplied significantly due to rapid changes on the global and regional markets of transport services. Today, many experts come to see this volatility as an indicator of the next phase in development of the global trade system and the derivative cargo transportation system, specifically the state of temporal saturation. The shift of the global goods volumes from quick and steady growth to relatively small fluctuations around constant values causes quick oscillations in re-distribution of demand over the oversized supply. This new business and economic environment seriously affected the paradigm of transport terminal design and development techniques. The new operational environment of terminals put a request for the designers to arrange the results not in terms of “point”, but in terms of “functions”. Eventually it resulted in development of the modern object-oriented model approach. The wide spread of this approach witnesses the objective demand for this discipline, while in many aspects it remains in the intuitive (pre-paradigmal) phase of its development. The main reason for it is in the problem definition itself, which usually is formulated as the simulation of a given terminal. At the same time, the task is to assess the operational characteristics of the terminal engaged in processing of a given combination of cargo flows. Consequently, it is not the terminal that should be simulated, but the processes of cargo flows handling performed by this terminal under investigation. Another problem that restricts the practical spread of simulation is in the model adequacy. A model which adequacy is not proved has no gnoseological value at all. The paper describes the approach aimed at development of the models with the features discussed above.

Opis:
The main purpose of the paper is to recognize and characterize the substantial trends and ongoing phenomena as well as processes on the supply and demand side of the global ocean container market and then evaluate their impact on global supply chains and the whole mega logistics system. The author has analysed the dynamics of potential supply and effective demand growth on this market in the recent years and assessed changes observed on both market sides with respect to global logistics area. On this basis, the influence of global container market development on global logistics supply chains has been estimated. There were also presented and analysed the main effects of speeding-up implementation of disruptive innovations such as blockchain technology and digital trade platforms development in maritime container transport and trade sectors on the efficiency and effectiveness of global logistics chains and the whole logistics area. The issues related to the security of smooth digital development of container maritime transport and the mega logistics area were taken into consideration as well.

Opis:
The main research issue refers to the identification and analysis of the key features and trends revealed on the global maritime container transport market in the years 2020-2022, as well as its general assessment in terms of the effects that such a highly concentrated market's supply side can cause for shippers and container shipping operators. The research is aimed at determining the main premises and factors stimulating the consolidation processes of the container shipping operators and ongoing market vertical and horizontal integration, as well as assessing the risks and effects resulting from maintaining the current system of regulation of this oligopolistic market. While conducting this research, the following methods were applied: factor analysis (FA), market analysis (MA) based on statistical data concerning the supply side, as well as desk research (DR), i.e. in-depth analysis of many reports, opinions, bulletins and data issued by international maritime organisations as well as research institutes. The obtained research results indicate that:1. the very advanced consolidation processes among the leading container shipping operators and, consequently, further integration of the container market, radically changes the balance of power in favour of shipping operators and creates the potential to generate serious disruptions in this market and other links in the global supply chains, 2/ regulatory antitrust authorities need to take appropriate regulatory action to limit their market power via legal measures regarding competition.

Opis:
Design and construction of container ships follow consolidated requirements, with standard consideration of fire management. Indeed, cargo fires can have important consequence on crewmembers and cargoes, as well as impacting coastal zone and marine environment. Innovative strategies include prevention of events and mitigation of consequences. Digital solutions, providing with situational pictures onboard and around the vessel are fundamental for new fire management solutions, seamless and integrated into the vessel IT infrastructure, according to IMO regulations and the recent EMSA CARGOSAFE Report. The assessment of these solutions requires theoretical evaluation, validation activities in simulated environment and demonstration activities in real environments, with use cases to prove feasibility and benefits. This paper, after a review of traditional preventing and mitigating solutions against fire and an analysis of container ships fires, proposes applicable innovative technologies and operational measures, emerging problems for their potential implementation and requirements for virtual and real tests design.

Opis:
The year 2022 was marked by economic risks with potentially very sensitive impacts for countries in the Black Sea region. Given the limited capacity of Ukrainian ports, as well as the sanctions imposed on Russia, due to ongoing conflict, it was necessary to identify new destinations capable of taking over the flow of goods that normally went to the countries involved in this conflict. In addition to the risks specific to maritime transport, the risk of armed conflict comes with new challenges that can also materialize in the form of environmental impact. To analyze this potential impact, the study is being focused mainly on the analysis of the pollution risk generated by the emissions caused by the vessels calling the container terminal CSCT, located in Constanța harbor, and the emissions generated by the vehicles moving in the terminal. As estimated from the start all levels of pollution have increased, with the level of CO2 increasing from 11072.7 tons in 2021 to 11915.7 tons in 2022. The NOx emissions have a similar trend, as well as the other emission level measured and calculated.
