In this paper, we study fixed-point theorems in metric spaces in the form of the fundamental part of nonlinear analysis and how they have been widely applied across numerous scientific and technical disciplines. Here is a comprehensive study of the application of these theorems, particularly focusing on contraction mappings and their role in ensuring the existence and uniqueness of fixed points in the interactive type. We constructed fixed-point models that accommodate uncertainty, iteration, and convergence which are -essential elements in real-world computations and simulations. Furthermore, we explore how these theoretical foundations can be applied to areas such as numerical algorithms, control theory, biological models, and engineering system design. Through illustrative examples and comparative analysis, these study demonstrates how fixed-point theorems can effectively solve dynamic problems in science and technology. The study reinforces the significance of fixed-point results as versatile tools for analyzing complex systems governed by deterministic and approximate behaviors.
