چکیده

به‌کارگیری تصمیم بهینه برای اولویت‏بندی عملیات اجرایی در پروژه‏های آبخیزداری برای کاهش خطرات بروز سیل به علت تأثیرپذیری از پارامترهای مختلف، پیچیده و البته مهم و ضروری است. تئوری بازی در به‌کارگیری تصمیم بهینه برای حل مسائل چندهدفه،کارایی بسیار زیادی دارد. در مطالعۀ حاضر، این روش برای اولویت‏بندی بر اساس خطر بروز سیل در حوضۀ آبخیز سزار مد نظر قرار گرفت و با استفاده از دو الگوریتم بوردا و چانه‏زنی در تئوری بازی، مؤثرترین پارامترها در تمامی زیرحوضه‏ها و نیز بحرانی‏ترین زیرحوضه‏ها مشخص شدند. با اجرای روش امتیازدهی بوردا، پارامترهای کاربری مسکونی با امتیاز 5/93، تراکم زهکشی با امتیاز 91 و شیب متوسط و شکل زیرحوضه با امتیاز 5/90 و درنتیجۀ اجرای الگوریتم چانه‏زنی، مؤثرترین پارامترها در رقابت بین 12 پارامتر در تمامی زیرحوضه‏ها، پارامترهای شیب متوسط، طول آبراهۀ اصلی و کاربری مراتع بودند که با توجه به اصول حاکم بر این روش، انتخاب پارامترهای یادشده برحسب دویدن تمامی بازیکن‏ها در همۀ میدان‏ها‌ست. درواقع، سه پارامتر نام‌برده در تمامی زیرحوضه‏ها سریع‌تر خودنمایی کردند و به عدد 16 که تعداد زیرحوضه‏هاست، رسیدند. درنهایت، نقشه‏های اولویت‏بندی زیرحوضه‏های سزار با هر دو روش ارائه شدند که در روش بوردا، زیرحوضه‏های I، N، G، P و O در اولویت نخست قرار داشته و در روش چانه‏زنی، G، H، N، I و F در اولویت نخست قرار دارند.

چکیده [English]

Making the optimal decision to prioritize the operation in watershed management projects is to reduce the risk of flooding due to the impact of various parameters, complex and, of course, important. The game theory has a high performance in making the optimal decision to solve multi-objective problems. In this study, this method was used to prioritize on the watershed of the flood risk in the Sezar watershed. By using two Borda algorithms and bargaining in game theory, the most effective parameters in all sub-watersheds and the most critical sub-watersheds were identified. By implementing the Borda scoring method, residential parameters with 93.5, drainage density of 91 and average slope, and the shape of the sub area with a score of 90.5, and hence the implementation of the bargaining algorithm, the most effective parameters in the competition between the 12 parameters in all sub-watersheds, Moderate slope parameters, length of the main waterways and rangelands were used. According to the principles governing this method, the selection of these parameters is based on the running of all players in all fields. In fact, the three parameters mentioned above are faster in all sub-watersheds, and the number 16 is the number Subways have arrived. Finally, the Sezar watershed Prioritization Plans are presented with both methods, which are in the first place under the Borda method, under the domains I, N, G, P and O, and in the bargaining chamber, G, H, N, I and F are in the first place.
