The background of the research was obtained from a practical system example of decision-making problems. The system can be described a functional part of the car, guiding the driver to the desired destination by the displaying route information. This is called a Car Navigation System. When this is used, the drivers depend on the route plan shown on the display. Based on the input given by the driver, the Car Navigation System shows the most efficient route based on time and distance. Generally, drivers do not drive the most direct route to the final destination point. In other words, usually when driving, even if a driver preplans the route, he will have a desire to make impulsive stops along the way. It can be said that the driver's subjective resource can be changed based on objective conditions. A rich description of this process comes, for example, from research on Trukese navigation the open sea reported by Thomas Gradwin (1964). The aim of the analysis then is to view the systematization decision-making process, including its assimilation, in items of constrains posed by asymmetries in the respective situation resources of subjectivity and objectivity. What is notable about Lucy A, Suchman (1987) account of the resources of the Trukese navigator is that nowhere is a preconceived plan in evidence. The basis for navigation seems to be, instead, local interactions with environment. The question of how a route map is produced for specific purpose, how in any actual instance it is interpreted vis-_-vis the situation, and how its use is resource for traversing the situation, is a reasonable and productive one. In the analysis, it is in the interaction of representation and represented where, the action is. In this decision-making model, the expected utility is derived from two influence degrees in the state space. It is an objective influence weights and a subjective influence weights. The relative criticality of the objective expected utility and subjective expected utility are determined for the final route of the expected utility based on preferred. There are three main results. 1. In the situated actions of the decision-making problem, the probability scale by the Markov property was applied to the evaluation based on the ratio scale constructed by the AHP. 2. The expected utility in each state of the decision making process was assimilated, and it weighed the expected utility of the objective item against the subjective item. 3. In the route path selection, the evaluation was done considering the evaluation based on the objective expected utility and the influence of the state transition between routes to other states Although the system's function (NAVI+) can guide the driver to the desired destination points, but it cannot forecast changes in driving conditions. This will not only be effective in Car Navigation Systems but the Markov property can also be used in other decision-making processes. In the future, there is a prospect for a new function of Car Navigation System based on the situated oriented expansion.
