In this article we will discuss about Managerial Decision-Making Environment: Concept of Decision-Making Environment 2. Decision-Making Environment under Uncertainty 3.
Concept of Decision-Making Environment: The distinction is drawn on the basis of the degree of knowledge or information possessed by the decision-maker. But there is a difference between the two concepts. Risk can be characterized as a state in which the decision-maker has only imperfect knowledge and incomplete information but is still able to assign probability estimates to the possible outcomes of a decision.
Risk is objective but uncertainty is subjective; risk can be measured or quantified but uncertainty cannot be. Modern decision theory is based on this distinction. In general, two approaches are used to estimate the probabilities of decision outcomes.
With the priori method, the decision-maker is able to derive probability estimates without carrying out any real world experiment or analysis. For example, we know that if we toss an unbiased coin, one of two equally likely outcomes i. Uncertainty does not seem to suggest that the decision-maker does not have any knowledge.
Some Characteristics of a Decision Problem: All business decision problems have certain common characteristics. These not only constitute a formal description of the problem but also provide the structure necessary for a solution: Alternative courses of action strategies 3. Events or outcomes 4.
The manufacturer of these has imposed a condition on you: You have to order in batches of But you cannot assign any probability estimate to the alternative levels of demand or sales.
It is not possible for you to wait for some time to study the nature or determine the level of demand, nor can you place more than one order. Thus, a situation of complete uncertainty prevails. The three alternative strategies are to order shirts A1A2 or A3.
The states of nature which are external to and beyond the control of the inventory manager are the events and in this case are three levels of demand: Since the inventory manager does not know which of the events will occur, he is forced to make his decision in the face of uncertain outcomes.
Thus we can say that a payoff matrix provides the decision-maker with quantitative measures of the payoff for each possible consequence and for each alternative under consideration. Positive payoff implies profit and negative pay-off implies loss.
For the T-shirts inventory and ordering problem, the payoff matrix is presented in Table 8. Decision-Making Environment under Uncertainty: Four major criteria that are based entirely on the payoff matrix approach are: The maximization of expected value.
It may be noted that once subjective probabilities are introduced, the distinction between risk and uncertainty gets blurred. The maximin or Wald criterion is often called the criterion of pessimism. That is, the decision-maker should choose the best of the worst.
In our T-shirt example the minimum payoffs associated with each of the actions are presented below: Thus, the criterion is conservative in nature and is well-suited to firms whose very survival is at stake because of losses.
An exactly opposite criterion is the maximax criterion.
The Maximin Approach Involves Choosing The Alternative With The Highest Or Lowest Payoff. Rawls' Maximin Principle: Is It Really The Most Rational Solution? Political philosophy aims to reflect the normative and conceptual dimensions of political life. American philosopher John Rawls is widely recognized as one of the leading political philosophers of the twentieth century. DECISION THEORY Steps involved in decision theory approach: •Determine the various alternative courses of actions from which the final decision has to be made. •Identify the possible outcomes, called the states of nature or events for the decision problem. c. selecting the alternative that has the lowest price. d. selecting the alternative that is the most reliable. e. choosing the alternative you think your boss would prefer.
It is known as the criterion of optimism because it is based on the assumption that nature is benevolent kind. Thus, this criterion is suitable to those who are particularly venturesome extreme risk takers.
The decision-maker would thus choose to order units because this offers the maximum possible payoff. The Hurwicz alpha criterion seeks to achieve a pragmatic compromise between the two extreme criteria presented above. The focus is on an index which is based on the derivation of a coefficient known as the coefficient of optimism.One incurs regret by “failing” to choose the “best” decision (the one with the highest profit or lowest cost).
Depending on the state of nature, you can find the max payoff for each state of nature. the maximin approach involves choosing the alternatives that has the best worst payoff (highest lowest outcome) TRUe decision tree problems should be analyzed backwards.
Note that, for any c >0, the maximin strategy is to choose an effort level of , which guarantees that player a payoff of (1 c). For a given Player i, any other strategy admits the possibility of a lower payoff since any effort level e i > yields payoff .
The maximin approach involves choosing the alternative with the highest or lowest payoff. Answer Selected Answer: False Correct Answer: False Documents Similar To Mat Strayer Quiz2 Week3.

|Game Theory through Examples||Leland The problems of how self-interested players can cooperate despite incentives to defect, and how players can coordinate despite the presence of multiple equilibria, are among the oldest and most fundamental in game theory.|
|Solution Preview:||For reasons to be discussed later, limitations in their mathematical framework initially made the theory applicable only under special and limited conditions.|
Uploaded by. SaideAnneChaar. The mixed maximin strategy is the mixed strategy with the highest lowest entry in the rowit is the mixed strategy that guarantees the highest expected payoff, Beth has a similar maximin strategy of choosing 1/3 "Left" and 2/3 "Right". The expected payoff for both when both play this strategy is 10/3.
