Note—Dynamic Facility Location and Simple Network Models

Wesolowsky [Wesolowsky, G. O. 1973. Dynamic facility location. Management Sci.19 (11, July) 1241–1248.] has examined a dynamic version of the location problem for a single facility, obtained by allowing relocation of the facility over time to optimize a cost or benefit expression. This problem is essentially one of facility replacement, and may be expressed and solved through a simple network model as in deterministic equipment replacement situations ([Veinott, A. F., Jr., H. M. Wagner. 1962. Optimal capacity and scheduling—I. Oper. Res.10 (4, July–August) 518–532 and Wagner, H. M. 1969. Principles of Operations Research. Prentice-Hall, Englewood Cliffs, New Jersey, pp. 180–181 and pp. 340–342.]).
