PROBLEM TO BE SOLVED: To provide a method for establishing an operation target value which is capable of automatically establishing an optimal final operation target value upon operating an apparatus such as a normal pressure distillation apparatus and the like when the switch of a raw material arises. SOLUTION: The method for establishing the operation target value of the various apparatuses at the time of the raw material switching comprises correlating data relating to the raw material treatment amount, data relating to the type of the raw material, data relating to the raw material of the individual type when the raw material is consisting of two or more types, data relating to apparatus operation including the amount of the withdrawal, the column top temperature and the column top flow rate and data relating to the quality of the fraction, accumulating them as the operation track record data in the data base, inputting the conditions relating to the raw material treatment amount after the switching, the conditions relating to the type of the raw material and the conditions relating to the quality of the fraction at the time of the switching and searching similar one or more among the operation track record data accumulated in the data base to establish the target value based on the operation track record data found at the result of the searching.
