Abstract

Establishing an observatory often involves complex decisions, such as choosing a site based on multiple conicting criteria. In this study, we develop a multi-criteria decision analysis process by combining Geographic Information System (GIS) analysis with the (MCDA) Multi-Criteria Decision Analysis and use this process to determine the most suitable sites for the construction of an observatory in the Malatya urban area. GIS was used to calculate, classify, and analyze criteria, while FAHP (Fuzzy Analytic Hierarchy Processes, Buckley's method) and BWM(MCDA type Best-Worst Method) methods were used to weight the decision criteria and determine their effects on alternative sites. While the Cloud Cover criterion in the BWM method was the most important criterion with 28%, the most important criterion for the FAHP method had a comparable value of 27.8%. Meteorological criteria were the most important criteria group with values of 50.4% according to the FAHP method and 44.6% according to the BWM method. The study is based on meteorological, geographic, and anthropogenic datasets, suggesting the most appropriate sites for the astronomical observatory within the boundaries of the study area. The proposed sites are the result of site selection, which is the first phase of site selection for astronomical observatories. This site selection is important to limit the number of field alternatives. It is necessary to conduct field tests among the proposed areas and select the final site according to the results. The successful use of GIS and more than one MCDA method will pave the way for the development of various methods for astronomical observatory site determination.
基于模糊层次分析法和BWM方法的天文台选址
建立观测站通常涉及复杂的决策,例如根据多种相互矛盾的标准选择地点。在本研究中,我们通过将地理信息系统(GIS)分析与(MCDA)多标准决策分析相结合,开发了一种多标准决策分析过程,并使用该过程确定在马拉提亚市区建设天文台的最合适地点。GIS用于计算、分类和分析标准,而FAHP(模糊层次分析法,巴克利方法)和BWM(MCDA类型最佳最差方法)方法用于权衡决策标准并确定其对备选地点的影响。而BWM方法中的云覆盖标准是最重要的标准,占28%,FAHP方法中最重要的标准具有27.8%的可比值。气象判据是最重要的判据组,FAHP法占50.4%,BWM法占44.6%。该研究基于气象、地理和人为数据集,建议在研究区域范围内最合适的天文台地点。选址是天文台选址的第一阶段,是选址的结果。这种选址对于限制备选场地的数量非常重要。有必要在建议区域之间进行实地试验,并根据结果选择最终地点。地理信息系统和多种MCDA方法的成功应用将为发展各种天文台选址方法铺平道路。
