Tétel Szabadon hozzáférhető Development of the Concept of Circular Supply Chain Management: A Systematic Review(2021) Lengyel, Péter; Bai, Attila; Gabnai, Zoltán; Mustafa, Othman Mohammad Ahmed; Balogh, Péter; Péter, Erzsébet; Tóth-Kaszás, Nikoletta; Németh, KornélTétel Szabadon hozzáférhető Direct Optimization of an Automotive Sheet Metal Part Using ANSYS(2020-12-10) Khalid, Usman; Mustafa, Othman Mohammad Ahmed; Naeem, Muhammad Ali; Alkhateeb, Mohammad Yousef Mohammad; Awad, Basil Marwan Abed EljaberOptimization of automotive parts nowadays is mainly used to design lightweight and cost-effective vehicle parts in order to improve the cost and efficiency. In this research, a sheet metal part was taken into consideration and optimized using direct optimization module in ANSYS to evaluate the process. An initial Finite Element Analysis (FEA) was done on the sheet metal part by adding forces and constraints in order to initiate direct optimization. The purpose of the optimization is to minimize the mass of the sheet metal part and maintaining a certain Factor of Safety (FOS) by automatically modifying the sheet thickness and the dimension of the side holes. As a result, the best candidate point with 23% mass reduction was found which complied with FOS value was selected for optimal geometry.Tétel Szabadon hozzáférhető Direct Optimization of an Automotive Sheet Metal Part Using ANSYS(2020) Khalid, Usman; Mustafa, Othman Mohammad Ahmed; Naeem, Muhammad Ali; Alkhateeb, Mohammad; Awad, Basil Marwan Abed EljaberTétel Szabadon hozzáférhető Embracing circular economy in FMCG supply chains: drivers and challenges in Jordan(2025) Mustafa, Othman Mohammad Ahmed; Lengyel, Péter József; Ihrig Károly gazdálkodás- és szervezéstudományok doktori iskolaThis doctoral research explores the drivers and barriers influencing the adoption of Circular Supply Chain Management (CSCM) practices in Jordan’s Fast-Moving Consumer Goods (FMCG) sector. Using a mixed-method approach combining bibliometric analysis, exploratory factor analysis, and structural equation modelling (SEM), the study identifies internal and external factors affecting CSCM implementation. Key drivers include employee involvement, corporate social responsibility (CSR), long-term sustainability orientation, and supplier cooperation, while major barriers encompass traditional organisational culture, inadequate information systems, and poor infrastructure. The findings contribute to both theory and practice by highlighting how CSR, cultural context, and regulatory frameworks uniquely shape CSCM in emerging markets. The study provides actionable insights for policymakers and industry leaders aiming to promote sustainable and circular business practices in developing economies.
