Improving product sustainability is becoming an increasingly significant challenge for modern enterprises. A growing number of manufacturers are interested in enhancing product sustainability throughout the product life cycle. This study is concerned with using case-based reasoning to identify ways of improving product sustainability and select variables for model specification. Parametric models are applied to search for opportunities to improve product sustainability. This can be achieved through changes introduced at the product design stage. Simulations are performed using constraint-satisfaction modeling to identify conditions for achieving the sustainability targets of new products. Constraint-satisfaction modeling provides a suitable framework for finding all possible sustainability-enhancing changes (if any) during the new product development process. These changes may support R&D specialists in identifying opportunities to improve the sustainability of new products. We demonstrate the usefulness of the proposed approach with an example in which our method enabled a reduction in the product failure rate and an increase of battery lifespan for a robot vacuum cleaner line. We analyzed several factors affecting two targets of product sustainability: minimizing the product failure rate and maximizing battery lifespan. Our findings indicate that R&D staff size is the biggest factor in reducing the product failure rate, and that battery capacity is the most significant factor in battery lifespan.

European Union (EU) countries are struggling with the high costs of operating healthcare facilities due to energy consumption. The rational use of resources, including renewable energy sources (RESs), is a goal of sustainable development in terms of solving environmental problems. There are few literature studies that analyze the impact of the use of RESs in the healthcare sector on the achievement of sustainable development goals in EU countries. This study examines the potential of RESs to address environmental challenges in EU healthcare systems and their impact on the Healthcare Index (HI). A quantitative analysis explores the relationship between the Environmental Performance Index (EPI), Environmental Health Score (EHS) and HI. Data were taken from Yale Center for Environmental Law and Policy (YCELP), European Environment Agency (EEA), and the Numbeo. This study assessed the relationship by using SPSS 29. This study concluded that RESs should be prioritized in healthcare facilities to increase environmental performance and thus meet sustainable development goals. The use of RESs affects environmental performance and improves HI. The results indicate significant positive correlations, highlighting the benefits of RES adoption for both environmental and health indicators.

Objectives: The aim of the study is to determine the scale of interregional migrating patients’ hospitalizations in Poland in 2013–2017, as well as their demographic and medical factors, total costs and time changes. Material and methods: Data from the NHF (National Health Fund)...
