Application of unified modelling language on firm's supply chain

Supply chain stages are known to be complex and variable. Variability and complexity increase due to the increased numbers of the stakeholders. Unified Modelling Language (UML) is known to be efficient in visualizing complex systems and highlighting both major and minor activities, hence provides stakeholders with better understanding and visualizing of the overall system. In this paper, UML models are developed and employed to model supply chain stages for a manufacturing firm. Functional, behavioral, and structural models are developed and explained throughout the paper. These UML models assist in understanding details of the supply chain process. The result is clear, well-structured models that facilitate the process of decision making, control, and improvement of the firm's supply chain. The models serve as the initial step for building an efficient ERP system that captures relevant details. © 2023 IEEE.
