The global demand for ballistic protection systems within civilian armored vehicles (CAVs), particularly in high-security environments, necessitates focused research. Given the paucity of literature addressing the ballistic enhancements design of non-military passenger vehicles, this work concerns the analysis of quality assurance during the armoring process of a standard civilian passenger vehicle while maintaining its original functionality and consumer guarantees. To achieve these metrics, the article presents the Design for Assembly and Armoring (DfA2) methodology in a case study, examining the protection of a front door system of a worldwide compact sport utility vehicle (SUV). This systematic framework optimizes lightweight ballistic systems for CAVs through empirical evaluations and engineering principles. Integrating manufacturing acumen with Design for Excellence (DfX) principles, quality assurance protocols, automotive performance criteria, and ballistic defense requirements, DfA2 addresses the development and integration of armoring solutions with product and process quality in CAVs. Through field research, this study demonstrates the efficacy of the proposed method in refining armoring operations, minimizing armor material mass, and reducing production and design expenditures. Consequently, the findings of this case study with the adoption of DfA2 suggest that the method can be replicated or adapted for diverse vehicle categories, encompassing hatchbacks, notchbacks, SUVs, and commercial vehicles. This research sought to standardize vehicle armoring production, ensuring rigorous quality control while preserving original vehicle functionalities and consumer warranties.

Climate policy goals have now taken on a strongly dominant role in European mobility development. In the current preferred approach, European OEMs are focusing on the BEV strategy, which is considered an established technology. However, the shift towards a purely battery-oriented direction in Europe is advanced, yet there are still long ways to go before speaking of complete market penetration. Meanwhile, Asian, and American providers have embedded themselves in the European market, threatening to snatch significant shares from European OEMs in the overall market. Therefore, a separate approach has emerged to determine possibilities for expanding the product portfolio to FCEVs in Europe, as this market is still in an early stage internationally. An empirical approach was used to identify the factors European OEMs see as implementation or barriers to an FCEV strategy. The results indicate generally that such a strategy extension appears feasible in many factors, yet there are hardly any implementations for real feasibility. Costs and model portfolios are particularly emphasized here. However, there are also cautious attitudes due to a lack of refuelling infrastructure and perceived insufficient demand on the customer side.

Supply chain resilience is a critical determinant of success in the automotive industry, particularly in emerging markets like Morocco. This research employs a comprehensive approach to identify and prioritize external logistical risks threatening automotive supply chains in Morocco. Through interviews with logistics specialists of multinational automotive companies, we utilized the fuzzy Analytic Hierarchy Process (AHP) and the fuzzy Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) to assess the weights of evaluation factors and rank the identified risks, respectively. Our findings reveal that catastrophic events in the factory, extreme weather conditions, and workers’ strikes/labor union issues are the top three risks posing the greatest threat to supply chains in Morocco. Additionally, challenges such as agitated political situations, high maintenance costs, and infrastructure limitations demand attention to enhance supply chain resilience. This research contributes to the understanding of supply chain risk management in emerging markets and offers practical insights for industry practitioners and policymakers aiming to fortify automotive supply chains in Morocco and similar contexts.

Safety cages, constituting essential equipment in sports car, aim to reduce consequences of potential accidents. These structures should provide the highest possible and reproducible level of workmanship aimed to ensure their strength as that assumed at the design stage. Because of the fact that welding is the primary technology used in the fabrication of safety cages it is highly necessary to analyse the effect of welding parameters as well as the choice of welding methods on process repeatability and strength properties of welded joints. The aim of this study was to determine the influence of the welding method on the strength of test cruciform joints of tubes as well as to investigate the effect resulting from the change of MAG and TIG welding current parameters on the linear deformation of welded joints. The article discusses the effect of welding process conditions on the static strength of cruciform joints in steel E355 +N (used in the fabrication of safety cages). The tests revealed that an increase in heat input during welding significantly reduced the strength of cruciform joints as well as significantly contributed to an increase in post-weld linear deformation, which, in terms of spatial safety of cage structure, could lead to a significant pile-up of stresses.

Klatki bezpieczeństwa są niezbędnym wyposażeniem samochodu sportowego, a ich zadaniem jest ograniczenie skutków potencjalnego wypadku. Konstrukcje te powinny zapewniać możliwie najwyższy oraz powtarzalny poziom wykonania, aby ich wytrzymałość była taka, jak założono na etapie projektowania. Z uwagi na fakt, że wiodącą technologią wytwarzania klatek bezpieczeństwa jest spawanie, istnieje istotna potrzeba analizy wpływu parametrów spawania oraz doboru metody na powtarzalność procesu oraz własności wytrzymałościowe połączeń spawanych. Celem badań było określenie wpływu metody spawania na wytrzymałość złączy modelowych w postaci złączy krzyżowych rur, jak również zbadanie wpływu zmiany parametrów prądowych spawania metodami MAG oraz TIG na odkształcenie liniowe złączy spawanych. W niniejszym artykule omówiono wpływ warunków technologicznych spawania na wytrzymałość statyczną połączeń krzyżowych ze stali E355 +N, wykorzystywanych do budowy klatek bezpieczeństwa. Udowodniono, że zwiększenie energii liniowej spawania znacząco obniża wytrzymałość połączeń w węzłach krzyżowych połączeń spawanych, a także istotnie przyczynia się do wzrostu odkształcenia liniowego po spawaniu, co w przypadku przestrzennej konstrukcji klatki bezpieczeństwa znacząco wpłynie na naprężenia w tych konstrukcjach.

The main purpose of this article is to prepare an appropriate plan for the development of the infrastructure of the Bieszczady region for the use of electric cars as the primary means of mass and private transport for residents and tourists in the Bieszczady region. Over the next few years, electric cars will be available to an increasing number of people, thanks to more affordable purchase costs. This is made possible due to the dissemination of technology on the market and the emergence of increasing competition in individual segments of the automotive industry. The decisive condition will be the appropriate infrastructural facilities – i.e., chargers for electric cars, both those “fast” for direct current (DC) and “slow” for alternating current (AC). The development of infrastructure directly contributes to the purchasing decisions of electric cars made by residents of a given territory or people traveling through a given country with their own cars in the context of potential supplementation of electricity. In the first part, a review of the literature on the topic of electric cars is introduced. The second part presents the Bieszczady region in the context of electromobility implementation. In the last part, a detailed analysis of the region’s infrastructure (roads and car parks) is prepared, and, as a consequence, places are selected where the construction of a charging station would be justified. During point selection, the key parameters are the current condition of the road and parking infrastructure, the number of residents and tourists in a given zone of the region, and the strategic importance of the region. This article presents a detailed infrastructure analysis of locations where charging stations could be installed, including their amounts and power, in the Bieszczady region. The latter is divided into communes (i.e., Ustrzyki Dolne, Czarna, and Lutowiska), which provide a total of 14 locations, 55 stations, and 113 charging points.

Armoring civilian vehicles requires specialized knowledge and experience that many armoring companies lack as they are not direct or indirect suppliers of vehicle manufacturers. This limits their access to automotive quality and manufacturing certifications or detailed vehicle designs, which can result in loss or malfunctioning of automotive components during the armoring process. Therefore, this study aimed to investigate the challenges faced by Brazilian civilian armoring companies and identify opportunities for improvement in their production processes. Qualitative research was conducted using a questionnaire-based survey of eight specialized firms in Brazil, as well as literature related to DFMA, design for manufacturing and assembly, quality, automotive, and ballistic references. The study results in clude detailed armoring operation steps, qualitative survey reports, and helpful literature references for armoring practitioners to generate a standard armoring procedure for different vehicle models. Following best practices in automotive and armoring procedures collected in the survey responses can standardize and enhance ballistic protection operations while preserving the original vehicle systems’ functionalities and warranties. This work provides valuable information for armoring companies to improve their operations and interfaces with automotive systems and follow automotive and ballistic references.

Background: An assembly line is a technique used in mass production industries, especially in the automotive industry; it consists of many workstations organized along a conveyor belt system or other material handling equipment. The assembly line balancing problem (ALBP) involves assigning assembly tasks to workstations on the line while meeting optimization goals. It is considered a critical issue in operations management because it directly affects the productivity of the entire manufacturing system. Methods: Based on the mathematical model previously developed by (Esmaeilbeigi, Naderi, and Charkhgard 2015) for the E-type SALBP problem, we proposed a new model adaptable to the automotive sector. The proposed model uses new feasibility rules and optimizes constraints in order to propose better balancing results and efficiency. Results: A computational experiment is presented in this article, using the newly developed model to balance an assembly line in an automotive manufacturing plant consisting of 5 workstations. Conclusions: The experimental results show that the proposed model improved the line efficiency by 15%, which proves that the proposed method has good robustness.

Background: Supply chain management (SCM) practices play a significant role in modern business success through coordinating the continuous flow of goods, services and information within complex networks. At this level, the collaboration between supply chain (SC) members constitutes an important determinant of supply chain performance. Therefore, this study aims to explore the effect of supply chain collaboration dimensions, i.e., such as decision synchronization, collaborative communication, incentive alignment, goal congruence, information sharing joint knowledge creation, and resource sharing, on the level of supply chain performance. Methods: The dataset was gathered using a convenience sampling procedure from middle and senior automotive SC executives. Partial least squares structural equation modeling (PLS-SEM) using SmartPLS software was carried out in order to analyze the data. Results: The results show that collaborative communication, information sharing, incentive alignment, joint knowledge creation, and goal congruence contribute considerably to enhancing the automotive SC performance. Conclusions: These findings have valuable implications for practitioners in order to adopt the appropriate practices to improve automotive SC performance. These insights can help to guide practitioners in implementing the appropriate collaborative practices to meet the specific challenges of the automotive supply chain. By considering these guidelines, practitioners will be able to streamline processes, optimize resource allocation and ultimately deliver more efficient outcomes, leading to improved overall automotive supply chain performance.

The article presents the most important causes of the unstable connection between cast iron ring inserts and the silumin casting of an engine piston. It is shown that manufacturing defects are mainly related to the alfin processing of inserts in Al-Si alloy (the so-called AS9 alloy). Exceeding the permissible iron content in AS9 alloy causes the crystallization of brittle -Al5FeSi phases. Their unfavorable morphology and large size are the main reasons for the weakening of the diffusion connection between the inserts and the piston, causing an unacceptable proportion of defective products. The study presented in this work was conducted under industrial conditions on a population of 10.000 pistons. Quality control data, production parameters, as well as the micro- and macro-structures of the cast iron inserts, and the interface area between the inserts and the silumin piston, were analyzed. Material and technological solutions have been proposed to reduce the occurrence of casting defects at the insert-piston joint. This includes the introduction of so-called "morphological correctors" of the -Al5FeSi phases, reducing the possibility of gaseous impurities in the AS9 alloy and optimizing the temperature of the alfin alloy.
