1. Does organizational support really influence satisfaction and well-being during enforced working from home?Marcin Butlewski, Wiktoria Czernecka, Piotr Janiszewski, Joanna Bogajewska-Danek, Brigita Gajšek, Marcin Suszyński, Jinal Parikh, 2024, original scientific article Abstract: Theoretical background: The transition to enforced working from home (EWfH) due to the COVID-19 pandemic has dramatically altered work dynamics, necessitating a reevaluation of traditional labor relations and service delivery. This shift underscores the need for comprehensive organizational support, with theoretical frameworks like the job demands-resources (JD-R) model and work-life boundary management theory highlighting the impact of remote work on employee well-being, productivity, and job satisfaction. These frameworks suggest that well-being is influenced by the balance between job demands and resources, and how individuals manage work-life boundaries, laying the groundwork for exploring how organizational support can address EWfH challenges. Purpose of the article: This article aims to delve into organizational support during EWfH and its impact on employee well-being. It focuses on identifying critical support aspects and their influence on subjective well-being, providing insights into effective remote work practices and guiding organizations in supporting their workforce post-pandemic. Research methods: Employing a mixed-methods approach, the study surveyed 429 Polish employees across different sectors, complemented by qualitative interviews for deeper insight. This methodology enabled the collection of comprehensive data on employer support perceptions and their impact on remote working well-being, analyzed through statistical and thematic analysis methods. Main findings: Key findings underscore the importance of effective communication, resource access, well-being support, and career growth opportunities as crucial organizational support aspects for remote employees. A significant correlation was found between organizational support levels and enhanced employee well-being, with higher support linked to reduced stress, improved work-life balance, and increased job satisfaction. The study also emphasizes the need for personalized support strategies, accounting for individual differences and home working environments, to foster a positive remote working experience and ensure long-term productivity and well-being. The main application of your paper, which examines the impact of company policies on employee well-being during EWfH, could be the development of a comprehensive guide or toolkit for organizations to better support their remote workforce. This application would be particularly relevant to HR departments, managers and organizational leaders.

2. Process simulate versus inertial Mocap system in human movement evaluationD. Lanzoni, Gregor Harih, Borut Buchmeister, Nataša Vujica-Herzog, 2024, original scientific article Abstract: There are various tools for evaluating physical ergonomics. Two main computer-assisted approaches can be recognized in the literature: analytical evaluation using simulation software like Siemens Jack or Process Simulate, and empirical evaluation by tracking human body movement. Both methods have their own advantages and disadvantages. This article compares an analytical method using Process Simulate software and an empirical evaluation using an inertial motion tracking system and highlights the strengths and limitations of both approaches. The information from the tracking system is processed by the Process Simulate software and an ad-hoc ergonomic analysis module developed in Unity. Given the limited license of Process Simulate, the ergonomic comparison is performed using two indices, RULA and OWAS. Other comparison metrics discussed in the article are the time required for the analysis, the additional functionality each solution offers and the possibility of augmenting the assessment with virtual or augmented reality solutions. The results show some limitations of using Process Simulate with the tracking data and the great versatility of the solution developed in Unity

3. Spatial modelling of the transport mode choice : application on the Vienna transport networkSimona Šinko, Bojan Rupnik, Klemen Prah, Tomaž Kramberger, 2021, original scientific article Abstract: A new approach for spatial modelling of transport mode choice is presented in the paper. The approach tackles the problem by considering the trade-off between subjective and objective factors. To obtain mode Preference Rates (PRs) based on subjective factors, the Analytic Hierarchy Process (AHP) method is applied. The objective factors are expressed with the journey time from any point in the map to destination according to the available transport mode choice on the specific connection. The results are presented as PRs of individual transport modes. The model is validated on the con-ducted the survey, with students of Vienna University of Economics and Business (WU) as a target audience. Members of different target groups (age, national, employment) decide differently regarding the transport choice, so it is better to analyse them separately. The presented model can be used for the city transport planning in any urban area. It can help promote the sustainable modes of transport in the areas that are less adjusted in sustainable manner.

4. Ergonomic evaluation of human–robot collaborative order picking : a combined laboratory and simulation studyMinqi Zhang, Jakob Marolt, Primož Bencak, Eric Grosse, Tone Lerher, 2024, published scientific conference contribution Abstract: Thanks to rapid technological developments in robotics, various automation technologies are being applied in warehouses today. Order picking, as a key process in warehouse operations, has drawn attention in academia and practice for decades. In addition to many studies dedicated to manual and fully automated order picking, efforts have also been made to study semi-automated warehouses in which humans and robots collaborate. However, these studies mostly focused on system efficiency and ignored ergonomic aspects. Order picking was confirmed as a labor-intensive process in an environment in which workers are at a high risk of developing health problems. Therefore, this study addresses the investigation of physical human working conditions in both manual and robot-assisted order picking systems via real-life laboratory experiments and simulation modeling. We used a motion capture system to assess human working postures when working with and without robot assistance. In addition, we estimated the daily workload by applying the energy expenditure concept. Using simulation experiments, we were able to extend the results to various practical scenarios with different design variables, for example warehouse layouts, order sizes, and human-robot team configuration. Our preliminary results reveal that human-robot collaboration can reduce human workload. Posture evaluation also shows a slight improvement.

5. Towards productive and ergonomic order picking : multi-objective modeling approachBrigita Gajšek, Simona Šinko, Tomaž Kramberger, Marcin Butlewski, Eren Özceylan, Goran Đukić, 2021, original scientific article Abstract: The logistics sector should strive for sustainability alongside productivity by protecting its order pickers' health and welfare. Existing storage assignment models are mainly based on the criterion of order picking time and, to a lesser extent, the human factor. In the paper, a solution to a storage assignment problem using a multi-objective model based on binary integer linear programing is presented by developing a solution that considers order picking time, energy expenditure and health risk. The Ovako Working Posture Assessment System (OWAS) method was used for health risk assessment. The downside of solely health risk-optimization is that the average order picking time increases by approximately 33 % compared to solely time-optimization. Contrary to this, the developed multi-objective function emphasizing time has proven to be promising in finding a compromise between the optimal order picking time and eliminating work situations with a very-high risk for injuries. Its use increases the time by only 3.8 % compared to solely time-optimization while significantly reducing health risk.

6. Bi-objective assignment model for lean order picking in a warehouseBrigita Gajšek, Hrvoje Cajner, Tihomir Opetuk, Goran Đukić, Marcin Butlewski, 2022, original scientific article Abstract: With the introduction of Lean Warehousing, we are committed to using lean principles for more efficient warehousing operations, which are performed with quality and safety. Manual order picking, on which the paper is focused, is currently considered the most unfriendly to humans because, in the long run, it contributes to the appearance of musculoskeletal disorders. We record not only the increase in the average age of employees in warehouses but also in the number and duration of sick leave due to back and muscle pain. This paper explores the possibility of productive work while preventing order pickers from Work-Related Musculoskeletal Disorders. Using a laboratory experiment, we determine retrieval times for units with different characteristics and study required postures by guidelines of Revised NIOSH Lifting Equation. The final goal is to create a bi-objective assignment model.

7. Use of ergonomic principles in manual order picking systemsNina Labus, Brigita Gajšek, 2018, original scientific article Abstract: Successful companies are continually striving to streamline costs and optimize processes, enabling them to grow progress, develop and ensure competitiveness on the market. A large part of the costs arises in warehouses, where up to 55% of total costs are generated by order- picking, which makes it important and interesting in terms of research. The paper explores "picker to part" order- picking concept, which enables flexible work and is the optimal choice for most companies. The concept is associated with a high level of work- related injuries and work -related illnesses. Work requires physical efforts resulting from handling heavy goods, performing repetitive movements and using manipulative means. Hum an as the main actor of the concept affects the costs caused by picking and the quality of work done, which depends on technological support, physically and psychologically capable and motivated people. Due to the high costs of service, the focus on time planning and productivity increases. Contrary, the lack of attention is paid to the working conditions and the health status of the pickers. To overcome this gab, a review of scientific and professional literature on ergonomic principles in picking concept "picker to part" was carried out, followed by a quantitative survey of ergonomic properties in warehousing activities. Results revealed that more than 60% of the surveyed order-pickers associate problems with health with the characteristics of work, about 24% of them associate health problems with the use of a particular means of transport, and all agree that provided measures to reduce physical effort and greater support of technologies influence on increased speed of work and better health status of order-pickers.

10. Improving products' ergonomic value using intelligent decision support systemJasmin Kaljun, Bojan Dolšak, 2012, original scientific article Abstract: During the process of defining suitable design solutions, a designer has to consider a wide range of influential factors. Ergonomics certainly belongs to more complex ones. Less experienced designers could encounter several problems during this design stage. Although some literature can be found about ergonomic design of hand tools, a designer still has to have amassed quite a lot of experience and knowledge in the field of ergonomic, in order to choose and carry out appropriate design and redesign actions. Existing computer tools for ergonomic design are not able to assist a designer with higher level advice within design process. An intelligent decision support system has been developed in order to overcome this bottleneck. This paper presents a knowledge base, containing ergonomic design knowledge specific for hand tools design. A pneumatic hammer handle design is used as a case study to show how ergonomic design knowledge built in the system is used to improve the ergonomic value of the product.
