In this work, we propose a multi-server queuing system for modeling the processes that occur in a maritime container terminal. In our study, the main operations that take place at the quay and in the yard are first disaggregated into several elementary activities. Then we propose the step-by-step calculation of the times of each operation that influences both the unloading and the loading of a container. Next, we analyze the vessel cycle time while separately investigating the STS (ship to shore) crane cycle time, the RTG (rubber tyred gantry) cycle time, as well as the IMV (internal movement vehicle) transfer time. Finally, we apply two process-driven simulation experiments to the system analysis. The paper demonstrates the proposed model’s effectiveness with data from the BCT Gdynia container terminal. We show that, among others, even with properly planned work of STS cranes and RTGs, there is still a high probability that the quay will become a bottleneck of the described processes.

This article provides the first research on the importance of technological and environmental factors in the context of innovation and strategic management in the film industry. The study employs semi structured interviews, a systematic literature review (SLR) and a computer-assisted web interview (CAWI). First, based on the interviews and SLR, it identifies the most important technological and environmental film business model adaption factors, four in each category. Then, the CAWI results indicate that technological factors supported by social and economic changes substantially impact the film business models, while environmental factors are of minor importance, although noticeable. As with any research, ours also has some limitations. The surveys were conducted with a limited number of experts who agreed to participate in the study. At the same time, the findings of SLR depend on the researchers’ choice of searched keywords, the language of the scrutinised texts and the selection of databases.

Artykuł jest pierwszym opracowaniem poświęconym badaniom znaczenia czynników technologicznych i środowiskowych w kontekście innowacji i zarządzania strategicznego w branży filmowej. W badaniu wykorzystano wywiady częściowo ustrukturyzowane, systematyczny przegląd literatury oraz wywiad internetowy wspomagany komputerowo (CAWI). Po pierwsze, na podstawie wywiadów i systematycznego przeglądu literatury, zidentyfikowano po cztery najważniejsze technologiczne i środowiskowe czynniki adaptacyjne filmowych modeli biznesowych. Następnie, na podstawie wyników badania CAWI, wskazano, że czynniki technologiczne wspierane zmianami społeczno-gospodarczymi w istotny sposób wpływają na modele biznesowe dystrybucji filmów, podczas gdy czynniki środowiskowe mają zauważalne, jednak mniejsze znaczenie. Jak każde badanie, również i to ma ograniczenia. Badania ankietowe przeprowadzono z ograniczoną liczbą ekspertów, którzy zgodzili się wziąć udział w badaniu, a wyniki systematycznego przeglądu literatury zależą od wyboru przez badaczy wyszukiwanych słów kluczowych, języka analizowanych tekstów oraz doboru baz danych.

Purpose: After the outbreak of the covid-19 pandemic and Russo-Ukrainian war, the situation in the Baltic Sea Region (BSR) changed, especially regarding maritime container terminals. The aim of the article is to identify major Baltic container terminals and to perform a multicriteria analysis of their competitiveness. The analysis will be carried out before (2019) and after (2022) the turmoil on the market in question. Design/methodology/approach: The study uses the Preference Ranking Organization Method for Enrichment Evaluations (PROMETHEE II) with subjective criteria weights, as well as the entropy method with objective criteria weights. Findings: The obtained results show that two Polish maritime container terminals, DCT Gdańsk and GCT Gdynia, as well as Finnish Vuossari can be assessed as the most competitive both in 2019 and 2022. At the same time, in the analyzed years, the lowest positions in the rankings were maintained by Swedish GCT Gavle and Vasthamnen, Finnish Euroports Finland as well as Latvian BCT Riga. Research limitations/implications: Limited data availability influenced the choice of criteria used in the study. Moreover, website data sources used in the study may result in the inaccuracy of our calculations. Finally, the subjectivity involved in the selection of chosen criteria and some of their weights could lead to different competitiveness assessment results of maritime container terminals in the BSR. Practical implications: Our findings should be of interest to terminal operators and managers planning their strategy for next years, especially if they want to maintain their competitive advantage in the region after the lifting of sanctions imposed on Russian ports. Originality/value: This is the first paper to compare the multicriteria rankings of competitiveness before and after the turmoil on the BSR container market, especially as industry reports and research on the BSR usually consider the annual results achieved by individual ports, ignoring the efficiency of the terminals that comprise them.

The article examines the competitiveness of small Baltic container terminals. In order to conduct the research, thirty terminals, whose annual maximum throughput capacity does not exceed 150,000 TEU, have been examined taking into consideration a number of criteria which are: length of the quay (C1), number of RTG (C2) and STS (C3) cranes, number of shortsea shipping connections (C4), maximum (technical) depth at the quay (C5), distance from motorways and expressways/national roads (C6), distance from the national railway station (C7). Selected k=7 criteria were used to perform PROMETHEE II (Preference Ranking Organization Method for Enrichment Evaluations II) multi-criteria ranking that enabled specifying those Baltic Sea container nodes which are in the area of strategic benefits for the analysed market sector.
