Meanwhile, production planning problems deal with maximizing the product amount to be produced. Decision-makers need to take optimal decisions for those problem to gain the maximal revenue. In this paper, a novel mathematical model in the class of probabilistic piecewise programming is proposed as a decision-making support that can be used to find the optimal decision in solving both integrated supplier selection and production planning problems involving discounts and probabilistic parameters. The objective is to gain the optimal performance of the supply chain, i.e., maximizing the profit from the production activity. The model covers multi-raw material, multi-supplier, multi-product, and multi-buyer situations. Numerical experiments were conducted to evaluate the proposed model and to illustrate how the optimal decision is taken. Results showed that the proposed decision-making support successfully solved the problem and provided the optimal decision for the given problem. Therefore, the proposed model can be implemented by decision-makers/managers in industries.","PeriodicalId":22384,"journal":{"name":"The Eurasia Proceedings of Science Technology Engineering and Mathematics","volume":"251 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136113071","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the high carbon footprint and global warming effects caused by non-renewable sources have made energy transition a key element to ensure sustainable development. Currently, hydrogen produced from water supplied by renewable energy is considered an ideal and sustainable energy carrier for the future. Herein, we investigate experimentally and theoretically using MatLab modeling the production of hydrogen via PV supplied alkaline electrolysis of water coupled to 40 kHz ultrasonic bath. Nickel plates and nickel foam were used as electrode’s material immerged in 25% of KOH electrolyte while a 12V solar panel was used as a green source of power supply. The experimental and the modeling results related to the ultrasounds effect on hydrogen production efficiency showed a high agreement. The integration of ultrasound showed a reduction in electrode coverage by bubbles of approximately 54.8%, which was equivalent to 9.32% of the reduction in cell voltage according to the experiments.","PeriodicalId":22384,"journal":{"name":"The Eurasia Proceedings of Science Technology Engineering and Mathematics","volume":"14 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136113841","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Solar power, wind energy and hydroelectric power are considered as alternatives that can meet our energy requirements. By incorporating these energy sources into our mix, we can reap benefits such as job creation and economic growth particularly in rural and remote areas. To evaluate the potential of energy production in 11 countries a study was conducted using Data Envelopment Analysis (DEA) EBM analysis. The study considered three factors; the number of patents related to renewable energy, the capacity of energy installations and the gross domestic product (GDP). The output that was analyzed focused on energy production. The countries included in this study were Australia, Brazil, China, France, Germany, Japan, Netherlands, South Korea, Spain United Kingdom, and United States. This study’s findings provide policymakers and investors with a framework for assessing each country’s capability to generate energy. This methodology offers insights that can guide policy decisions concerning energy production across different nations.","PeriodicalId":22384,"journal":{"name":"The Eurasia Proceedings of Science Technology Engineering and Mathematics","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136113508","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In particular, the world of illustration, corporate design/design planning, translation, film production, copywriting, virtual education is all undergoing significant and irreversible change. In this article, we summarize what can be known about the impact of AI-assisted digital applications on the labour market for the illustration professionals. Based on exploratory research used in-depth interviews, opinions are markedly divided. Some see AI-assisted applications as a new opportunity, a rapid development of a hybrid toolkit to gain a competitive advantage. Others argue that they represent a threat to daily livelihoods and devalue hand-made creative work. According to business leaders, they can deliver significant cost savings without compromising on the level of quality expected, and on the contrary, they can enhance the user experience.","PeriodicalId":22384,"journal":{"name":"The Eurasia Proceedings of Science Technology Engineering and Mathematics","volume":"177 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136114587","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
