Production planning is an important step in supply chain management of refinery enterprises. Based on TBP（true boiling point）distillation

this paper describes the foundation of TBP cut points optimization

and analyzes the feasibility of TBP cut points optimization according to laboratory data of distillates’properties(such as octane number and cetane number ) and cut points. Optimizing the TBP cut points in production planning of refinery was proposed.Studies on TBP cut points optimization were carried out and related LP (liner programming)models were developed under the same crude oil type and feedstock and other production constraints.The case study showed that the optimal TBP cut points could produce higher value products

greatly increasing profit in refinery.
