Grey Wolf Optimızation Algorithm In Project Scheduling Problems: An Application In The Museum Design Sector

2025-01-30T00:03:23+03:00

In this study, the aim is to address the scheduling problem encountered in the project management of a company operating in the museum design sector by utilizing the Grey Wolf Optimization (GWO) algorithm, a meta-heuristic approach. The completion times of 19 different activities related to the project scheduling problem addressed in the research, which teams will undertake the activities, the precedencies related to the activities and the constraints encountered in the problem are known. The scheduling problem, which focuses on the processes related to interior design and the creation of exhibition spaces, aims to minimize the completion time. The solution to the problem, along with its data and constraints, was obtained using the Grey Wolf Optimization algorithm implemented in Python. The company set a target completion time of 260 days, while the Critical Path Method (CPM) calculated a duration of 242 days. However, the applied GWO method reordered tasks within the framework of constraints and variables, achieving a completion time of 213 days. This outcome represents a successful result compared to the initially defined timeframes. Consequently, solving a real operational process problem in the museum design sector with a successful outcome highlights the originality of this research.

Housing Prices In Turkey: Macroeconomic Factors and Structural Changes

2025-04-17T10:35:59+03:00

This study examines the effects of macroeconomic variables on housing prices in Turkey within the framework of structural breaks. Given Turkey’s geopolitical position and its frequent economic fluctuations driven by both domestic and external dynamics, the originality of this study lies in conducting all analyses by incorporating structural breaks. The empirical analysis utilizes monthly data from 2015 to 2023, employing time series methods to investigate the determinants of housing prices. By considering structural breaks in all analyses, the study emphasizes long-term and permanent effects rather than short-term economic shocks. The analyses are conducted within the framework of supply-side and demand-side variables. The results indicate a significant causal relationship between cement production, construction cost index, and the housing price index among supply-side variables. However, no direct relationship is found between building permits and the housing price index. On the demand side, a significant causal relationship is identified between the housing price index and all demand-side variables. The findings highlight that structural breaks are a crucial determinant of the housing market and provide valuable insights for policymakers regarding the long-term effects of macroeconomic variables.

Energy Poverty, Income Distribution, and Macroeconomic Stability: An Evaluation from the Perspective of Sustainable Development

2025-06-04T19:48:49+03:00

This study approaches energy poverty not merely as an issue of physical access to energy but as a multidimensional development problem, considering its implications for income distribution inequalities, social exclusion, regional development disparities, and macroeconomic stability. Through analyses conducted on the case of Turkey, it is observed that energy poverty is particularly concentrated in the Eastern and Southeastern Anatolia regions, disproportionately affecting vulnerable groups due to infrastructural deficiencies, low income levels, and insufficient social protection mechanisms. It is observed that some households in these regions are unable to adequately heat their homes and struggle to afford energy costs. This situation positions energy poverty not only as a matter of individual welfare loss but also as a structural problem that deepens social inequalities and economic vulnerabilities. In this study, policy recommendations are developed to reduce inequalities in energy access, including enhancing social assistance through more precise targeting mechanisms, promoting energy efficiency projects, and encouraging local renewable energy solutions. Moreover, it is emphasized that energy poverty should be addressed not only within the framework of social policy but also from the perspective of macroeconomic stability. In this context, the study underscores the need to restructure energy policies with a holistic approach that prioritizes social justice, economic balance, and environmental sustainability in line with sustainable development goals.
