Abstract
In some recent papers [2], [3], a state-space discretization technique was presented for the optimal stopping and impulse control of piecewise deterministic processes which reduce the aforementioned problems to a sequence of one-dimensional minimizations. In this note, we show that by doing a time discretization on the set of stopping times the aforementioned problems can be solved via linear programming (LP). Moreover, we present a method that can considerably reduce the number of inequalities of the LP problem. An application to the maintenance of complex systems is given.
