Salesman: Vende or Not vende Buying: Purchase the 2 or purchase What it is observed is not that in this situation it does not have a consensus position, being that probably the business will not occur. What it is easily verifiable for the presented matrix. The objective of this analysis is to demonstrate that so that the business occurs it will be necessary that both the sides still search the balance, what can be gotten way flexibilizao of the value, or of the conditions of the business, therefore so that both reach its objectives and occur a game IT EARNS? IT EARNS, is basic that the transaction if materialize. The Theory of the Games also is applicable for the analysis of investments, being very common the use of elaborated trees of decision, that allow to mapear the options and to evaluate its impacts, with sights if to opt to the alternative most adequate. It notices that we present the concept of more adequate decision, therefore nor always is possible to reach the yield highest or the lesser costs, without running high risks.
The idea of the matrix of the decision has for purpose to make possible the knowledge of the alternatives and to make possible establishment of occurrence probabilities, as demonstrated below. We go to admit that a company has the possibility to install or not a store in a new Shopping and that its competitor also can be studying this possibility.
