Optimization Modeling for Sustainable Production and Scheduling of Crude Palm Oil Milling Industries

Crude palm oil (CPO) can be obtained from the milling process of raw materials, called fresh fruit bunch (FFB) into end products palm oil. The process usually through a series of steps producing and consuming intermediate products. The CPO milling industry considered in this paper does not have oil palm plantation, therefore the FFB are supplied by several public oil palm plantations. Due to the limited availability of FFB, then it is necessary to choose from which plantations would be appropriate. This paper proposes a mixed integer linear programming model for the supply chain integrated problem, considering waste. The mathematical programming model is solved using neighborhood search approach.
