This thesis is a research which proposes a decision supporting system for production planning and scheduling in a kraft paper industry. The decision supporting system is developed on a personal computer with Microsoft Visual Basic 6.0 and Microsoft Access 97 by preparing problems into the transportation model. The system is used to schedule production grouping by paper grade which aimed to minimum loss. Then it is used to calculate the initial solution by the Vogel's Approximation Method and to calculate the objective solution by the Modi Method. This method aims to the optimum solution that are minimum total production cost. This system is tested by using the historical data and is implemented in a model factory. The result shows that the decision supporting system can reduce the total production cost which comes from planning about from 1.2 to 9.3 million bath in each month. It can increase the reliable of the information of the decision making. It also reduces planner's skill requirement, planning time and facilitates to change a plan promptly.
