In the paper, the problem of machine replacement in the changing technological environment is formulated as a problem in modern control theory. The objective is to maximize the present value of all future net profits over a class of infinite chains of machines where each link in the chain represents a uniform length replacement cycle with identical preventive maintenance. The control is affected by varying the length of the replacement cycle, and the schedule of preventive maintenance. The optimal control is determined by applying the maximum principle of Pontryagin and resulting influence functions are provided economic interpretations. Author
