Development of a new calculation core for premium adjustment of a private health insurance company

Due to statutory requirements and rising costs for medical care, the premiums of private health insurance tariffs must be adjusted regularly. A comprehensive set of rules is used to decide which tariff must be changed by which amount for which group of people. There are several adjustment runs spread over the year, each of which covers a specific tariff group. The definition of the parameters for the set of rules lies with the specialist department, so the newly developed calculation core must be parameterized in a format that the specialist department can supply.
