This work is basically divided into four parts. In the first part the foundations of i4.0 are discussed and accruals are given for any i4.0 project.In the second part the basics of investment calculations are repeated and a transformation system, including an unified nomenclature, is given for the Discounted Cash Flow (DCF) method of E. Fischer into that of A. Rappaport and vice versa. Here a transformed system from Rappaport is used to determine the value of a project, in the limit case that the investment expenses are equal to the depreciation of fixed capital (depreciation), and that additional working capital investments are zero, the same results are obtained, as with the system of Fischer.Finally, in the third and fourth part, two i4.0 examples are given, a fictitious investment and a real investment of the J. Pichler GmbH.Here, by means of Fischers system, the project value is calculated for four different scenarios. According to the previously derived option value theory, which means that project values can be splitted into option values of action implementation, it results that in the first fictitious i4.0 example, the action implementation corresponds to linear i4.0 option values, meaning that different action implementations are independent of the particular strategy, or action implementation. On the other side, in the i4.0 example of the J. Pichler GmbH, a nonlinear i4.0 option value for the simultaneous implementation of two different strategies can be identified and displayed in an option value matrix, making simultaneous implementation advantageous.
