Fixed Facility Location Techniques Available to Purchase

Plant location has been an enigma for planners since the Middle Ages. As early as 1647 Cavaliere tried to find a point which minimised the distance between three given locations. A special case of this problem was formulated by Heinen in 1834. Fagano increased the problem from one considering three points to one of four. Fagano's work was extended to the case of n points by Tedenat in 1810.
