The accuracy of the income allotment algorithmic model used for evaluation of technical
assets is dependent on the determination of each parameter, and this is also a problem that is easy to
arouse controversies. A way for calculating the income allotment proportion in the pricing model of
income separation is introduced. The different meanings of several expected revenues and their
determination methods are expounded. The calculation methods for discount rates and for different
technical assets and their life periods are put forward, and some problems that need to be paid
attention to are also put forward. Finally, a practical example is used for analysis of the income
separation.
