Mobile supply chain management is one of the systems that provide managing petrol transportation efficiently. The application of mobile technology, allow the information of petrol transportation to retrieve ubiquitously and ordering process can be done immediately. It will help the sales executive from the oil and gas company to closely monitor and ensure good delivery of petrol to customers. Thus, this study aims to design a requirement model for mobile supply chain management system for petrol transportation in one of the oil and gas company in Malaysia. The model will provide a better guideline for the mobile system developer to design and develop the system accordingly. There are three main phases involved in the study which are defining, analyzing, and validating requirements. Nevertheless the study only focused on capturing the functional requirements using Unified Modeling Language (UML) and concluded the constraints arose during the course of producing the model. I. INTRODUCTION Nowadays, fleet management system, become one of the elements that contribute to current fleet's productivity and reduce working capital requirements by lowering operational expenses. In addition, the fleet management had become the business challenge in order to find the right alliance of technologies and services to unleash the full management potential. In order for the fleet management company to stay in touch with their marketing and sales information, mobile communication become the component that provide specialized needs to them (Salkintzis, 1999). Silva and Mateus (2003) stated that a lot of opportunities can be created with the combination of three technologies which are Internet, mobile communication and location technologies. Thus, to exhibit the usefulness of mobile fleet management system, petrol transportation is one the services that employed the application of information technologies which can provide the return on investment to the company. In order to establish a well defined mobile fleet management system, analysts or developers of the system need to understand all the requirements needed to build the system. According to Silva and Paton (2000), analyst used requirement model as a data flow model to represent the functional requirement and operational concept as the basis of the design guidelines. Pertaining to this, Unified Modeling Language (UML) has various uses in many different applications and become the industrial standard language for object oriented analysis and designs (Nunes, 2000). Therefore, this study is aimed to design the requirements model using UML model. Petronas Dagangan Berhad (PDB) has been chosen as the case study since the oil and gas multinational company provide petrol supply services for the petrol station in Malaysia.
