Mathematical model for decision making in production of upstream Para rubber product in the supply chain
Abstract:
Para rubber farmers have to use their experience to decide their volume of production in order to make the highest profit. Farmers need to concern about many constraints to find the optimal-solution. This research presents the mathematical models in order to solve the product mix decision problem of the upstream Para rubber products based on Bottleneck method. Necessary constraints such as workstation time limit, machine capacity, raw material requirement, raw material limit and maximum volume were added. Two mathematical models were created to solve product mix decision problem for both a production unit and all production units under the total demand. The objective function is to maximize the profit. Lingo 11 was used to solve the problem. These models were applied to solve the product mix decision problem in two sub-districts, Rayong province. The mathematical model of product mix decision for a production unit provided the production volume and found the maximum profit for each farmer. The mathematical model of product mix decision for all production units under the total demand allocated the production volume to each farmer based on their resources. The constraints of models could utilize the farmer resources properly.
