A significant share of food waste originates in the food services domain and HoReCa (hotels, restaurants, catering) sector. Organizational improvements leading to the decrease of food waste and costs in restaurants are needed. The literature reports on applications of lean management in service businesses, and while food services belong in this category, the literature contains few works on specific applications in this domain. Those studies are limited mainly to economic aspects. Nor was there evidence of the applicability of lean management to achieve food waste elimination. This article analyzes the applicability of lean management methods for food services in order to achieve efficient operations and eliminate food waste, based on a literature review and three case studies from Poland. Lean management was found to be useful in these cases to decrease food waste and reduce operational costs. The case studies suggest a set of activities for organizations delivering food services to streamline their processes by applying lean management practices. This study contributes to the theory and practice of sustainable restaurant management.

A significant share of food waste originates in the food services domain and HoReCa sector. Organizational improvements leading to the decrease of food waste and related costs in HoReCa are needed to make progress in this issue. A systems engineering approach was applied to examine the links between food waste generated in the HoReCa industry and the Sustainable Development Goals (SDGs). A literature review discovered two dimensions of actions leading to decreasing food waste in HoReCa; i.e., actions triggered by companies and by authorities (e.g., governmental policies). Additionally, customers and society were also considered. A framework is proposed to explicitly illustrate the dependencies of different micro actions devoted to food waste reduction in HoReCa in support of the SDGs. The other dimension of this framework is macro policies and their impact on SDGs. To increase food waste reduction awareness and collaboration, stakeholders on both the macro (launched by authorities for the whole sector) and micro (initiated by single organizations on their own) levels must work together. The results of this research will be useful in coordinating the efforts of all (consumers, HoReCa companies and suppliers, policymakers and administrations on different levels) involved in the supply chain of food production and consumption.

The automotive industry is undergoing significant changes due to increased connectivity, data usage, and vehicle autonomy, which pose new challenges and increase the attack surface of vehicles. To effectively address these challenges, all design tasks in automotive projects need to be well-coordinated and prioritize vehicle security. Model-Based Systems Engineering (MBSE) provides a comprehensive approach that allows multiple engineering disciplines to work concurrently. In this study, we propose the integration of well-established security solutions, such as Security Patterns, into safety-critical automotive systems using the MBSE approach. Our work presents a procedural flow for incorporating Security Patterns into the system model, emphasizing the inclusion of cybersecurity (CySe) and functional safety (FS) actions. To meet the regulatory requirements, we selected the IDS (Intrusion Detection System) pattern as a key component of our proposed CyberSafety Design Framework. In a real-world case study of an Advanced Emergency Braking System (AEBS), we evaluated the effectiveness of our framework by integrating the IDS pattern with TARA and HARA assessments. Our results demonstrate the feasibility of merging design processes within an MBSE framework, reducing design effort and aligning with the security by design principle. Future research should explore the application of different Security Patterns in conjunction with SOTIF systems, and industry efforts should be directed towards standardizing the collaboration between cybersecurity and safety.

The transformation trend towards digital technology to achieve sustainability targets and meet legal regulations has been visible in many industries. The printing sector has already been increasingly boosting sustainability performance through digitalization to automate workflows of processes. The goal of this paper is to initially diagnose a sustainable performance of Printing 4.0 (Industry 4.0 in the printing sector). To achieve this goal, qualitative interviews were carried out with representatives of 11 printing companies. Results of the diagnostic study showed that advanced technologies have had a positive impact on sustainability in the analyzed printing companies due to a higher awareness of sustainability. It was observed in the surveyed sample that interviewees confirmed such an assumption. These companies that tailor their operational activities toward digitalization have more quickly noticed a positive effect on their sustainable businesses. This survey has served as a basis for more extensive research.

The SARS-CoV-2 pandemic is spreading rapidly and threatening lives all over the globe. Due to the pandemic, economies all over the world are in deep distress due to disruption in work and operations across all sectors. The present case study was performed for a private Indian manufacturing company that has been affected to a great extent due to this pandemic, as India has the second highest number of SARS-CoV-2 cases after the USA. The deeply troubled company’s current predicament is very complex, as various factors are responsible for the crisis. In order to restore the company back to normal functioning, these factors were studied and evaluated. A diagnostic survey was conducted to obtain data about current working conditions of company. Data from the survey were analyzed qualitatively and quantitatively to identify and evaluate the disruptive factors. Based on this analysis, problems in operational activities were identified and appropriate improvement actions (best practices) were proposed. Furthermore, the proposed improvement actions were assessed from a sustainability perspective to check their feasibility. The best practices framework was generalized to a three-step continuous improvement framework oriented around preparedness for future pandemic-like disruptions. The proposed framework may constitute an indication and set of best practices for consideration by other manufacturing companies that find themselves in a similar situation to the analyzed case study.

The automotive sector is facing challenges in terms of the requirements for guaranteeing the safety and security of cars. In respect of the engineering process, it is challenging to incorporate functional safety, safety of the intended functionality, and cybersecurity requirements into electrical vehicles. All of these aspects impact not only the vehicles or ECUs produced, but also the structures of the organizations by which the products are created. Based on current standards, drafts of future standards, and an analysis of the performance of a real design process for the ECU of an electrical vehicle, we propose an integrated design framework from the perspective of cybersecurity. Therefore, a stronger emphasis is placed on correct estimations of cybersecurity activity processes. As they affect all areas of development, these estimations cannot be isolated considering the ECU’s design process. More cooperation between various stages of the process is required in order to provide complete products at an early stage of design and development. The challenge is the identification of overlapping activities and the combination of design efforts in order to reduce the time and costs of an engineering project. A dedicated process entity will be proposed to an engineering division to manage cybersecurity processes.
