Petroglyphs are a form of human artistic expression that can be found in various locations around the world, displaying similar features despite being created in different eras. This art form, commonly found in mountainous and rocky areas, is often associated with shepherds and hunters. The themes depicted in petroglyphs typically revolve around hunting scenes, weapons, goats, sheep, dogs, and other activities related to hunting and herding. However, religious motifs can also be observed in some cases. While a variety of petroglyphs can be found throughout Iran, sites in central regions such as Yazd province have received less attention from archaeologists due to the desert climate. The petroglyphs we will discuss in this article are located in the Chah Abdullah region of south Yazd province, in central Iran. In 2021, the author conducted an archaeological survey of Harat City, identifying various cultural and historical sites from different periods. While most of the sites identified were historical monuments, several historical sites, including the Chah Abdullah petroglyphs, were also discovered. Based on the type of motifs and the depth of carving, this site is associated with different historical periods. However, it is fascinating that the creation of rock motifs continues even in contemporary times.

Objective : This research aims to propose a multi-criteria decision-making model for ranking hospital departments. The primary purpose of this model is to assist managers in the optimal allocation of limited resources, thereby reducing costs while increasing patient satisfaction. The ranking results help managers in decision-making processes such as equipment development, staff training, and addressing patient complaints. Methods : This study evaluated the performance of five hospital departments (Emergency, Ophthalmology, Cardiovascular, Infectious, and Neurology) in Shiraz, Iran, using the fuzzy DEMATEL-MARCOS multi-criteria decision-making method. Firstly, criteria were prioritized using the fuzzy DEMATEL method, after which hospital departments were ranked using the fuzzy MARCOS method. A sensitivity analysis was conducted to validate the results. Results : Performance metrics for the hospital departments were identified based on the Lean, Agile, Resilient, Green, and Sustainable (LARGS) paradigm. The results revealed that patient satisfaction and job satisfaction had the most substantial influence on performance, while reducing excess transportation and over-processing had the least impact. Utilizing the fuzzy MARCOS method, the hospital departments were ranked according to their overall desirability. The sensitivity of these rankings was assessed by adjusting the weights of the criteria. A comparative analysis with four other fuzzy methods (ARAS, COCOSO, EDAS, and WASPAS) confirmed that the fuzzy MARCOS method was the most effective tool for prioritizing hospital departments. Conclusion : The fuzzy MARCOS results indicated that the “Infectious Department” performed well, while the “Ophthalmology Department” required improvement. Enhancing the “Infectious Department” hinged on better staff training, cost reduction, and safe waste management. This research introduces a novel approach using the fuzzy DEMATEL-MARCOS model, enabling hospitals to assess performance through modern methodologies, such as Lean, Agile, Resilient, Green, and Sustainable, even in uncertain conditions
