The unique and demanding world of aviation always demands better, smarter, and more dynamic solutions for aircraft maintenance. The key driver of the search for new state-of-the-art developments is the need to minimize aircraft downtime. While traditional methods have proven their usefulness with small maintenance hubs, they can struggle to achieve efficient performance in larger operational maintenance environments. Often, realworld scenarios demand multiple dynamic constraints, such as fluctuating delivery dates, resource limitations, material shortages, and work package changes. Ultimately, these changes will require a fast response to accommodate, but at the same time, try to achieve the most efficient way for aircraft redelivery. This paper presents a novel and adaptive module for scheduling and planning designed to reshape how maintenance planning is conducted within the aviation industry. By utilizing constraint programming and modeling, the proposed method aids in making decisions about maintenance planning and scheduling to reduce aircraft downtime by maximizing the utilization of skilled workers, which, in turn, will reflect positively on operational efficiency. This work advances transport planning by providing a scalable, data-driven framework customized to the changing requirements of modern aviation maintenance.

Grand Lomé, Togo’s metropolis and capital city, is experiencing an urban explosion that is creating enormous road and traffic management challenges. Mobility is increasingly marked by heavy congestion, traffic congestion caused by businesses, and illegal parking on the roads, aggravating road safety challenges. This research project aims to analyze the influence of poor road management on the mobility of the population of Grand Lomé. The methodological approach involved drawing up an inventory of the road network through observation and interviews with the stakeholders and road users. The results reveal a lack of appropriate road layout on the one hand and poor management of traffic flow, the absence of parking areas, and poor enforcement on the other. The road network is substandard. The main roads do not have sidewalks or crosswalks. Most of the sidewalks that do exist on some new roads are narrow and illegally occupied by businesses, preventing non-motorized transport users from benefiting from them. Bicycle paths are virtually non-existent on new lanes, which highlights the lane configuration problem. In order to ensure sustainable mobility in cities like Lomé, it is essential to optimize the road network and traffic conditions.

Sedimentary mineral deposits are generally tabular and sub-horizontal, composed of one or multiple welldefined seams, arranged over large extensions, and when close to the surface, they are mined by Surface mining methods. These geometric characteristics make it suitable for the application of the strip mining method as an alternative to the traditional open-pit mining method, which allows the reduction of the truck haulage fleet and the costs associated with waste disposal. Consequently, it reduces the greenhouse gas emissions and carbon footprint associated with excavation and transportation processes. This article presents a two-stage mathematical model based on Integer Linear Programming to address the mine sequencing problem of a strip mining operation in a bauxite deposit, encompassing the allocation of a heterogeneous fleet of excavators. The model is solved through Constraint Programming, an approach first used in strip mining problems. The first stage resulted in a near-optimal solution for panels that reached 94,80% of optimality in 639 seconds for the proposed mathematical model, which is an acceptable computational time. In turn, the second stage resulted in an optimal solution for strips that is more realistic and reached 94,87% of the first stage’s objective function value in just 9 seconds.

With the continuous development of remote sensing technology and the widespread application of high-resolution remote sensing images, digital landscape design based on high-resolution remote sensing image interpretation is gradually becoming a new design concept and method. This study is based on high-resolution remote sensing images to classify gardens, and combined with ground survey data, statistical analysis software is used to invert the landscape elements of gardens. The experimental results showed that the R2 value was relatively large, while the MRE and RMSE values were small, indicating that the analysis results were close to the true values and the fitting effect was relatively ideal. The overall image segmentation was excellent, with an average diameter at breast height of 8.0-17.0 cm, mixing degree of 0.4-0.6, vertical diversity of 0.5-0.8, and a clear forest hierarchy when the average density was between 800-1100 plants/hm2. This indicates that the quality of landscape architecture designed at this landscape scale changes significantly and the effect is good. Digital landscape design based on high-resolution remote sensing image interpretation can not only improve design efficiency and accuracy, but also provide strong support for the sustainable development of urban planning and landscape design.

This study discusses the results of research into changes in the tourist traffic in port cities, which may pose challenges to the planning of city logistics. The analysis draws on the statistical data on tourism. The study sample includes four cities located in Poland’s two coastal areas at the Baltic Sea: Szczecin and Świnoujście (West Pomeranian region), and Gdańsk and Gdynia (Pomeranian region). Covering the years 1995–2022, the analysis has been complemented with a review of the literature on the role of city logistics in solving problems caused by the development of tourism. The rapid growth of tourism generates an increased flow of people, goods, and information, which may be detrimental to the smooth functioning of a city. Insights into the development of tourist traffic over the years may facilitate the planning of city logistics and reconcile the function of a tourist destination with that of a port, which the cities have to perform. It may also support efforts that aim to ensure the sustainable development of port cities.

Purpose: As with any organisation, one of the most important prerequisites for the effective operation of a research institute is proper planning of its functioning – that is, accurately defining the future and establishing all the resources necessary for scientific, financial and economic activities. This paper is an attempt to illustrate the importance of planning the activities of a research institute over different time horizons for its proper functioning. Design/methodology/approach: To solve the research problem posed in this way, the following was used: (1) a method of analysing and critiquing the literature through literature studies leading to a possibly multifaceted presentation of the issue of planning the functioning of a research institute and (2) a document examination method involving the collection of source materials, which were: financial plans, prospective directions of scientific, development and implementation activities, thematic directional plans for scientific research and development work, the institute's strategy and the procedures and practices used to prepare the plans. Findings: The research shows that the planning process at the research institute is subject to the requirements of the applicable regulations. This implies the necessity to draw up four types of plans in terms of: prospective directions of scientific, development and implementation activities, directional thematic plans of scientific research and development works and annual activity and financial plans. Originality/value: In the article, the authors attempt to adapt universal planning principles to the specific activities of research institutes. This is a new issue and a response to practical needs.

Kołobrzeg, podobnie do innych miast na tzw. Ziemiach Odzyskanych, uległ znacznemu zniszczeniu w wyniku działań wojennych w 1945. Pomimo strat w przedwojennej tkance miejskiej pozostałości dawnego układu urbanistycznego pozostały nadal widoczne. Zaistniałe procesy urbanistyczne można podzielić na kilka wyraźnie zdefiniowanych okresów, kształtowanych przez decyzje polityczne i zmieniające się trendy architektoniczne. Artykuł analizuje przemiany urbanistyczne w Kołobrzegu po II wojnie światowej oraz ich kontekst społeczny, polityczny i kulturowy. Autorzy proponują analizę genezy procesów decyzyjnych, prac projektowych i odbudowy zabytków w celu lepszego zrozumienia ewolucji przestrzennej miasta. Badania oparte są na kwerendach archiwalnych, analizie źródeł i przeprowadzone z wykorzystaniem metody porównawczej. Podkreślone zostały specyficzne problemy związane z odbudową miast w okresie Polski Ludowej, w tym konflikt między służbami konserwatorskimi a pragmatycznym podejściem władz.

Kołobrzeg, like other cities in the so-called “Recovered Territories,” suffered extensively during the military operations of 1945. Despite the losses in the prewar city fabric, the remains of the former urban plan remained visible. The postwar urban processes cab be divided into three clearly defined periods affected by political decisions and changing architectural trends. This paper analyzes the urban transformations in Kołobrzeg and their social, political and cultural context. The authors present an analysis od the genesis of decision-making processes, design work and reconstruction of historic buildings to better analyze the city’s spatial evolution. The study is based on archive queries, source analyses and the use of a comparative method. The paper emphasizes the specific problems concerning the reconstruction of cities in Poland during the communist period, including the conflict between the conservation services and the pragmatic approach of the authorities.

he most effective solution for reducing the substantial electricity consumption in office buildings and hospitals is to utilize rooftops for Solar Power Plants (SPP). One such building with this potential is Makassar Eye Hospital. The research process initiates with the identification of issues concerning electricity availability and daily consumption at Makassar Eye Hospital, as well as an evaluation of solar radiation potential. Subsequently, the design of a SPP system takes place. In addition to this, a location assessment is performed using various tools to gather the requisite data for the SPP design. In this research, the planning process utilized Homer software, encompassing both technical analysis based on electrical energy production and system performance calculations. Furthermore, economic analysis involved assessing the capital costs for installing the SPP based on current market component prices. Capital return costs were calculated based on the feasibility of the SPP investment. The feasibility was determined through calculations of the Payback Period (PP), Net Present Value (NPV), Internal Rate of Return (IRR), Profitability Index (PI), and Return on Investment (ROI). The results of the economic analysis indicate that the initial investment cost for SPP is Rp. 329.878.378. The energy production value per kWh is Rp. 955, with a PP value of 4,44 years, NPV value of Rp. 453.174.500, IRR of 25,0%, and ROI of 27,9%. These findings demonstrate the feasibility of the SPP project at Makassar Eye Hospital, as the IRR exceeds the Discount Rate (8.43%).

Najskuteczniejszym rozwiązaniem pozwalającym na zmniejszenie znacznego zużycia energii elektrycznej w budynkach biurowych i szpitalach jest wykorzystanie dachów pod elektrownie słoneczne (SPP). Jednym z takich budynków o takim potencjale jest Szpital Okulistyczny Makassar. Proces badawczy rozpoczyna się od identyfikacji zagadnień dotyczących dostępności i dziennego zużycia energii elektrycznej w Makassar Eye Hospital, a także oceny potencjału promieniowania słonecznego. Następnie następuje projektowanie systemu SPP. Oprócz tego przeprowadzana jest ocena lokalizacji przy użyciu różnych narzędzi w celu zebrania danych wymaganych do projektu SPP. W badaniach tych w procesie planowania wykorzystano oprogramowanie Homer, obejmujące zarówno analizę techniczną opartą na produkcji energii elektrycznej, jak i obliczenia wydajności systemu. Ponadto analiza ekonomiczna obejmowała ocenę kosztów kapitałowych instalacji SPP w oparciu o aktualne ceny komponentów rynkowych. Koszty zwrotu kapitału obliczono na podstawie wykonalności inwestycji SPP. Wykonalność określono poprzez obliczenia okresu zwrotu (PP), wartości bieżącej netto (NPV), wewnętrznej stopy zwrotu (IRR), wskaźnika rentowności (PI) i zwrotu z inwestycji (ROI). Wyniki analizy ekonomicznej wskazują, że początkowy koszt inwestycji w SPP wynosi Rp. 329.878.378. Wartość produkcji energii na kWh wynosi Rp. 955, o wartości PP 4,44 lat, wartości NPV Rp. 453.174.500, IRR 25,0% i ROI 27,9%. Ustalenia te wskazują na wykonalność projektu SPP w szpitalu okulistycznym Makassar Eye Hospital, ponieważ IRR przekracza stopę dyskontową (8.43%).

It is critical to estimate the workforce requirements for the production of blocks in shipbuilding. In this study, the number of workforce (man-day) required for the production of a passenger ship’s double bottom block was estimated. Initially, the production of the block was observed, and the average working performance of the mounting, welding, and grinding workers was recorded. Block drawings were examined and the work required was calculated. The amount of work increased, depending on any revisions required due to incorrect or incomplete designs. The average working performance of an employee is uncertain due to environmental factors, including the weather and working conditions, as well as health (both physical and mental). A two-stage stochastic programming model with recourse was established to estimate man-day required and a Sample Average Approximation (SAA) technique was used to obtain a near-optimum solution. The results of the study were compared with shipyard records and an agreement of approximately 90% was achieved.

Istanbul, a city celebrated for its deep historical roots and cultural diversity, reflects the confluence of numerous civilizations. This essay examines the preservation methodologies designed for the Suleymaniye District, a significant World Heritage Site on Istanbul's historic peninsula. Istanbul's geographical location has positioned it as a crossroads of various eras, from ancient hunter-gatherer societies to the present. This has endowed the city with a complex tapestry of cultural layers, both above and below ground. To ensure the preservation of this heritage for future generations, conservation-focused strategies are integral to the city's planning. The Historic Peninsula, Sarayburnu, the Suleymaniye Ottoman Residential Fabric, and the Zeyrek Traditional Neighborhood Fabric with its Black Walls are listed on the UNESCO World Heritage List. Yet, beyond recognition, these areas require robust conservation efforts to fulfill both national and international commitments. Since being designated a renewal area in 2006, the Suleymaniye District has undergone significant changes, shifting from individual to collective ownership. This transition has led to considerable heritage losses. To counter these challenges, the Istanbul Metropolitan Municipality (IMM) launched a conservation study in 2020, led by its Cultural Heritage Department. The study focuses on a 9-hectare area of timber housing, where much of the original fabric has been lost. Using a multidisciplinary approach, the project delves into the city's layers, developing strategies that address both above-ground and underground cultural assets. The study's uniqueness lies in its scalable methodology, integrating historical sources and oral histories to reconstruct the district's lost texture and "authenticity." The research identifies potential underground cultural assets and proposes priority actions for their conservation. In conclusion, the study seeks to rejuvenate the Suleymaniye District, transforming it into a "living" area that meets modern needs while preserving its historical essence. In this paper, we will introduce the current conditions of the Suleymaniye District with a special focus on their historical narratives. Later, we will explain in detail the methodology established for inter-scale and multidisciplinary evaluation of the data gathered for the site. Further, we will describe the approaches established for the preservation of the World Heritage Site. Finally, we will discuss the results of these methodologies through cases within the designated area.

Krakow is one of Poland’s most important cultural heritage treasures, but many tourists only visit the city’s iconinc and world-famous monuments. Far fewer people take a walk around the entire Old Town, visit the former suburbs of Krakow, not to mention the parts further afield. The reason for this can be attributed, among other things, to an insufficient number of marked tourist routes that would, on the one hand, encourage people to visit these areas and, on the other hand, be a motivating factor for better exposition of valuable landscape forms. Such measures are already becoming increasingly popular in Poland, also in rural areas, where newly designed tourist routes serve to exhibit even the smallest forms of cultural heritage and encourage tourists to visit a given region. This paper presents student designs of tourist routes running along the northern and southern sides of Krakow’s Old Town, together with the result of the pre-design research on which they were based. From a didactic point of view, they provided an opportunity to sensitise future landscape architects to the beauty and necessity of protecting and displaying Poland’s cultural heritage, both within and outside historic cities. When made available to the public, these routes can encourage people to visit more places of interest in and around the old town of Krakow, with a particular attention to the various forms of urban greenery, as well as their better exhibition and, in turn, the revalorisation of non-existent or forgotten landscape elements.

Kraków jest jednym z najważniejszych skarbów dziedzictwa kulturowego Polski, ale wielu turystów odwiedza tylko kultowe i znane na całym świecie zabytki miasta. Znacznie mniej osób spaceruje po całym Starym Mieście, odwiedza dawne przedmieścia Krakowa, nie wspominając o częściach bardziej oddalonych. Przyczyną tego może być między innymi niewystarczająca liczba oznakowanych tras turystycznych, które z jednej strony zachęcałyby do odwiedzenia tych obszarów, a z drugiej strony byłyby czynnikiem motywującym do lepszej ekspozycji cennych form krajobrazowych. Takie działania stają się coraz bardziej popularne w Polsce, również na terenach wiejskich, gdzie nowo projektowane trasy turystyczne służą do eksponowania nawet najmniejszych form dziedzictwa kulturowego i zachęcają turystów do odwiedzenia danego regionu. W artykule przedstawiono studenckie projekty tras turystycznych biegnących wzdłuż północnej i południowej strony krakowskiego Starego Miasta wraz z wynikami badań przedprojektowych, na których się opierały. Z punktu widzenia dydaktycznego dały one okazję do uwrażliwienia przyszłych architektów krajobrazu na piękno i konieczność ochrony i eksponowania dziedzictwa kulturowego Polski, zarówno wewnątrz, jak i na zewnątrz miast historycznych. Udostępnione publicznie trasy mogą zachęcić ludzi do odwiedzenia większej liczby interesujących miejsc na Starym Mieście w Krakowie i jego okolicach, ze szczególnym uwzględnieniem różnorodnych form zieleni miejskiej, jej lepszej ekspozycji, a tym samym rewaloryzacji nieistniejących lub zapomnianych elementów krajobrazu.

Teaching programming poses countless challenges. One of them is determining the most effective notation to introduce coding concepts to beginners. This paper examines the merits and drawbacks of introducing block-based, text-based, or both notations at the same time when it comes to learning basic programming concepts. In this empirical study, we report on a controlled experiment during short-term visits that promoted programming in primary schools. Our multinational study divided participants into three groups, one using block-based, the other text-based, and one using both notations. After training, participants were solving practical programming assignments. The study results revealed that participants' performance was not influenced by notation usage, as there was no statistical significance between the three groups. However, the performance outcomes were correlated with the duration of the sessions. Our findings from the controlled experiment suggest that educators can confidently utilize different notations while teaching beginners the first steps in programming.

Railroad transportation plays a vital role in the future of sustainable mobility. Besides building new infrastructure, capacity can be improved by modern train control systems, e.g., based on moving blocks. At the same time, there is only limited work on how to optimally route trains using the potential gained by these systems. Recently, an initial approach for train routing with moving block control has been proposed to address this demand. However, detailed evaluations on so-called lazy constraints are missing, and no publicly available implementation exists. In this work, we close this gap by providing an extended approach as well as a flexible open-source implementation that can use different solving strategies. Using that, we experimentally evaluate what choices should be made when implementing a lazy constraint approach. The corresponding implementation and benchmarks are publicly available as part of the Munich Train Control Toolkit (MTCT) at https://github.com/cda-tum/mtct.
