An approximation method is provided for calculating the present worth of nonintegrable continuous cash flows that have common industrial economic applications. Two limiting cases of particular use in engineering screening analyses are given for each model. Practical examples are presented to illustrate the application of the cash flow models to manpower reductions due to computerized process control and to cash flows for a pollution-abatement facility.
