“…The random index is one of the most popular and most effectively used decision-making methods developed by Saaty (Shyamprasad & Kousalya, 2020). Random index values are assigned according to Saaty's scale, and in the present case, RI = 1.56.…”

Research background: Circular economy is of great importance, as it plays a vital role in ensuring the reuse of waste created and, therefore, reduces the waste of limited resources, which is the primary goal of the general economic concept. In line with the circular economy, sustainable development gains great attention, as the United Nations announced the sustainable development goals that should be reached by 2030. Hence, the current paper aims at examining whether the circular economy could be treated as an effective assistance tool for sustainable development of OECD countries. Purpose of the article: The paper aims to investigate whether the circular economy could serve as an assistance tool for sustainable development and, therefore, seeks to determine if the circular economy could directly impact a country?s sustainable development. Methods: First, the countries chosen were prioritised using the Analytic Hierarchy Process (AHP) and the Evaluation Based on Distance from Average Solution (EDAS) methodologies. AHP method was used for weight assignment to the circular economy indicators that were further used for OECD countries? prioritisation procedure for which multi-criteria decision-making method EDAS was employed. Second, to reveal a link between the circular economy ranking results and sustainable development, a comparative analysis was done. Third, the impact of the country?s circular economy on sustainable development was evaluated using the fixed-effect regression model on four years of panel data from 2016 to 2019 for the sample of 32 OECD countries. Findings & value-added: The comparative analysis of the circular economy?s prioritisation results and Sustainable Development Goals Index (SDGI) ranking showed 20 out of 32 matches, assuming a link between the circular economy and sustainable development could be made. The fixed-effect regression equation results demonstrate that the unemployment rate, poverty rate, air pollution exposure, and CO2 emission per capita negatively influence sustainable development. In contrast, indicators such as gross domestic expenditure on R&D, renewable energy, number of passenger cars in use, and households with Internet access positively impact SDGI. The hypothesis that the circular economy is seen as an assistance for sustainable development and directly affects a country?s sustainability was approved. The paper contributes to the scientific literature in the field of circular economy and sustainable development interaction and could be seen as an assumption for new research directions, focusing on the linkage between circular economy and sustainable development. Moreover, the obtained results could contribute to a country?s policy-makers by highlighting the essential indicators of a circular economy that should be considered while forming the strategy of a country?s sustainable development.

“…where RI stands for the random index used in the literature [51]. If the consistency ratio (CR) is 0, that is, the consistency index is 0, the consistency of the pairwise comparison matrix is excellent [52] and the approved upper limit for CR is the value 0.1 [53]. This means that the pairwise comparison matrix becomes inconsistent as the consistency index increases.…”

“…A new comparison matrix must be developed in order to increase consistency if the final consistency ratio is higher than this amount (i.e., 0.1) [53]. The random index provided calculates the average values of consistency index and depends on the order of comparison matrices [52].…”

The right choice of polymeric materials plays a vital role in the successful design and manufacture of flexible fluidic systems, as well as heat transfer devices such as pulsating heat pipes. The decision to choose an acceptable polymeric material entails a variety of evaluation criteria because there are numerous competing materials available today, each with its own properties, applications, benefits, and drawbacks. In this study, a comparative hybrid multi-criteria decision-making (MCDM) model is proposed for evaluating suitable polymeric materials for the fabrication of flexible pulsating heat pipes. The decision model consists of fourteen evaluation criteria and twelve alternative materials. For this purpose, three different hybrid MCDM methods were applied to solve the material selection problems (i.e., AHP-GRA, AHP-CoCoSo, and AHP-VIKOR). According to the results obtained, PTFE, PE, and PP showed promising properties. In addition, Spearman’s rank correlation analysis was performed, and the hybrid methods used produced consistent rankings with each other. By applying MCDM methods, it was concluded that PTFE is the most suitable material to be preferred for manufacturing flexible pulsating heat pipes. In addition to this result, PE and PP are among the best alternatives that can be recommended after PTFE. The study supports the use of MCDM techniques to rank material choices and enhance the selection procedure. The research will greatly assist industrial managers and academics involved in the selection process of polymeric materials.

The construction industry is a significant part of the gross domestic product of any country, and its success can lead to the long-term economic and social development of lives in general. Many studies have found a positive link between public infrastructure and the economy. Infrastructure investment directly affects economic growth. Well-designed infrastructure will have long-term financial benefits. The Ministry of Public Works and Housing (Pekerjaan Umum dan Perumahan Rakyat / PUPR) has played an essential role in strengthening the monitoring and evaluation of the implementation of infrastructure development by local authorities, including making the right policies in determining infrastructure development priorities. The Analytical Hierarchy Process (AHP) and Bayes method were used in this study. First, we used AHP to derive independent weights for criteria. Then, we determined the closeness between priorities to produce a sequence of infrastructure development priorities. Based on the results, using Analytical Hierarchy Process (AHP) and Bayes Method showed that Lampihong-Panaitan, Halong-Tabuan, and Bihara-Tariwin roads are Priorities for development. Then the Wangkili-Pudak road, and finally, the Awayan-Bihara. Decision support systems using the AHP and Bayes methods can determine priorities for road infrastructure development at the Office of Public Works and Public Housing in Balangan Regency.
