The Western Australian Government Railways Commission (WestRail) employs several thousands workersunder many different awards. The awards serve to dictate the working and pay conditions of all employees of WestRail. Currently, tens of thousands of recorded time-sheets are processed per year. The present time-sheet processing system is predominantly batch-based and inefficient due to the complexities of many awards and conditions. Consequently, WestRail plans to streamline the entire time-sheet process to a suite of on-line systems. One of the steps towards this goal is to examine the potentials of applying expert system (ES) technology to the complex structures of many different awards.This paper describes an experimental expert system for award implementation at WestRail. The aims in this project are two folds. Firstly, it is to demonstrate to WestRail that the complex award conditions can be captured and applied using the currently available ES technology. The second objective is to show the viability of interfacing the ES with a database. From the results of study, it has been demonstrated that the ES techniques can be used to gather and interpret information from manual time-sheets that are subject to a complex arbitration award. Furthermore, it is believed that the ES technology can and should be integrated into the mainstream programming techniques at WestRail
