A study on multicriteria decision making in irrigation planning

A case study of Arignar Anna Suger Mill in Kurungulam, Thanjavur, Tamil Nadu, India. Located on Grand River. The project is mainly meant for irrigation and the command area lies within latitudes $10A∘^38a^∁Z0"$ and Longitude $10A∘^38a^∁Z0"$⁠. The Cavery River and the Grand River are the sources of two canal systems. When examining real-world scenarios, multi-criteria decision-making (MCDM) is commonly understood as a method that uses a variety of qualitative and quantitative criteria in certain, uncertain, and dangerous circumstances to recommend a suitable course of action, choice, strategy, or policy among the available possibilities. When there are competing and non-commensurable criteria and more people involved in making judgments, the situation will get more complicated. Instead of crisp real values between zero and one, requirements in this methodology are represented by interval valued fuzzy sets (real interval). Decision values and similarity degrees range from 0 to 1. The more resemblance and decision there is between interval-valued fuzzy sets, the higher the value. The best possibility is the one that has the greatest degree of decision and similarity.
