PT Perkebunan Tambi is one of the biggest plantation and processing tea factories in Central Java. Three plantation units of PT Perkebunan Tambi are Tambi Plantation Unit, Bedakah Plantation Unit, and Tanjung Sari Plantation Unit, where 52% of tea produced by Tambi Plantation Unit. There has been some decrease in Tambi Plantation Unit profit for the past few years due to the fact that there is no method to prioritize client’s orders. The goal of the research is to design a decision model to prioritize orders so the factory gets the best profit with minimum risks. The research uses AHP and PROMETHEE to design the decision model. AHP is used to determine the weights of the criteria, while PROMETHEE is used to prioritize tea order alternatives from the clients of Tambi Plantation Unit. There are five respondents that help the research, every one of them contributes to give information related to the criteria. There are seven criteria in consideration to prioritize orders: the complexity of production processes, grade, time, client’s behaviour, the amount of order, client’s status, and client’s character. The criteria are used to test three data sets. The result of the research shows that the decision model could build a production schedule where the orders produced without any overtime. Data set 1 is done within 18 days, data set 2 is done within 22 days, and data set 3 is done within 18 days.
