The paper proposes the use of the DEMATEL method (Decision Making Trial and Evaluation Laboratory) for the identification and analysis of cause and effect relationships between sustainable development indicators. The literature studies presented, among other things, the application potential of the selected multi-criteria method, with particular emphasis on the decision-making problems related to sustainable development. Then, on the selected example of the group of sustainable development indicators, the algorithm of the DEMATEL method was presented, its potential advantages and limitations in the context of update Sustainable Development Indicator modules of the Central Statistical Office. The priority objective of the work was to present the DEMATEL method and its main element, i.e. cause-effect chain (impact-relation map) as an alternative approach to the known P-S-R system, i.e. the division of indicators into three functional groups: pressure/cause indicators, state/effect indicators, and response indicators.

Over the past decades, demand for innovation in diverse industries, including the maritime industry, has been steadily growing. One of the primary sources of innovation has been the finding of inventive solutions to the most challenging problems. Until recently, the search for inventive ideas relied heavily on random and chaotic methods of boosting creative capabilities, thus drastically reducing productivity in the generation of new concepts and solutions. With the emergence of systematic methods for generating inventive solutions, the situation has changed. Modern methods such as TRIZ suggest a process of solving problems in a systematic way whereby each phase of the process is supported by the relevant analytical techniques and heuristic tools. This article presents Root Conflict Analysis (RCA+), a technique for problem analysis developed for the top-down decomposition of problems to chains of causes and contradictions. The article provides an example of applying RCA+ to discover the causes and contradictions which led a ferry to lose stability at sea.
