The location of a firm on a network

摘要: Since the pioneering work of Launhardt and Weber (1909), location theory firm has developed from a particular model in which decision criterion is minimisation transportation costs.1 Actually it not surprising that this model, called hereafter Weberian, still basic reference field spite its difference with neo-classical firm. One only to remember minor position held by spatial economics mainstream over several decades.2 Despite appearances, theoreticl hiatus no serious consequences for study problems. Indeed, Weberian now appears be short-cut leading model. The argument simple will used propositions chapter: place maximises profit at same time minimises cost included profit.3 Consequently, characteristics solution remain valid solution. This explains why, some parts chapter, we follow lines proofs given elsewhere. Unfortunately, there are exceptions equivalence rule which, surprisingly, correspond problems easy deal both theoretical numerical points view. Such problem discussed section 3.
