Evaluating Quality of Ziggurat of Ur Using Fuzzy Logic Concept and Fuzzy Logic Models

During the ancient civilizations many methods and techniques were used to build and construct structures, roads, bridges and buildings. Most of these methods and techniques are similar to what is being used nowadays. The significance of these methods and techniques is evaluated and estimated using linguistic expression specifically when dealing with ambiguous condition. These linguistic expressions are usually imprecise, and unclearly defined, yet extraordinarily useful. Using these imprecise expressions will make it difficult to apply mathematical calculations in order to conclude a crisp result with regard to project condition and structure quality. To avoid such difficulty, it is therefore essential to find a solution; that is the use of the concept of fuzzy logic and fuzzy set models. In using the fuzzy set models, it is applicable to manipulate certain expressions and transform them to numerical values on which mathematical calculations can be applied to acquire the consequences of variables and overall conclusion. This thesis presents and discusses three different fuzzy models: 1) The Angular Model, 2) The Translational Model, and 3) Triangular Model. The three models discussed are illustrated using C-Sharp programming language for user-friendliness. Each of the developed models has its own unique calculation process and has its encompassed advantages. The reason behind illustrating three different models is to allow for preference and selection of different users so they can compare between the features of each model and make their own decision in using the model of their choice. These models are used to evaluate the overall quality of the ziggurat and to estimate the integrity of the of the construction process of the ziggurat. Furthermore, the thesis presents an illustration of an intelligent system. An intelligent system program is illustrated to find the quality of the Ziggurat of Ur (Zigg-Ex) via evaluating the reliability of two factors that affect the structure directly. This computer program suggested by the study can be used as an attempt to help evaluate the overall quality of the Ziggurat of Ur.
