PSAU consumers cooperative main goal is to help improve the quality of life of its members and thereby contribute to inclusive growth, enterprise development, and employment. The objective of the study is to find the number of products per variation to be merchandised in obtaining the optimum (maximum) profit to support the PSAU consumers cooperative in solving problems and maximizing revenues. The researcher used a descriptive-exploratory type of research in this study. Traditional method and excel were used in solving the optimum solution. The researcher used three hundred ten (310) different kinds of products with different variations for the variables, selling price, and merchandising cost for objective function and number of operating days, and daily demand for the constraints. The study obtained an optimum profit of P3,931,966.56 from the resulted optimization model. The study further revealed the following top three quantities of products per variation to be merchandised: 43,854 pieces of medium egg, 29,141 pieces of extra-large eggs and 22,147 pieces of green 555 sardines. On the other hand, the least number of products to be merchandised were kamatis, mango and maxwell 150g. Based on the acquired results, the researcher recommends the following: first, other programs in solving the optimum solution such as AMPL software, CPLEX, MATLAB, integer programming, and Maple may be used. Second, the profit optimization model of this research may be implemented in PSAU Consumers Cooperative to assess its effectiveness. Lastly, future research on the other field of businesses using profit optimization may be considered. Keywords: Optimization, PSAU consumers cooperative, profit, products.
