An Optimization Model for Product Mix Decision Under TOC for Para Rubber Products

Since the prices of Para rubber products in Thailand are fluctuated. Farmers have to use their experience to decide to produce the products which make the highest profit. Each farmer has the different constraint resources which can make the different volume of production. The volumes of Para rubber products can be optimized by using a mathematical model for product mix decision under TOC. This paper proposes an optimization model used for Para rubber product mix decision under TOC to decide the volumes of products and maximize profit base on time evaluation using LINGO 11 to solve the problem. The objective function was to maximize the profit by considering income and additive cost. This model is applied to the one of the Para rubber farmer at Rayong province.
