What are some conditions under which business decisions are made using subjective probability concep

Share on Facebook Most every business decision you make relates to some aspect of probability.

A preference model is a representation of the value judgments needed for decision making. I recommend using a utility function for representing preferences.

The utility function may be a single-attribute utility functionin which case it represents that there is only a single decision objective e. A multi-attribute utility function may be used to represent multiple decision objectives and to express willingness to tradeoff achievement of the different objectives.

A utility function may also be used to represent risk aversion I recommend using an exponential utility functionin which case risk preference is captured by a single parameter called risk tolerance. If a decision produces outcomes that occur over time, time preference is typically represented by using discounting to collapse those outcomes into an equivalent present valuein which case the discount rate is a necessary value judgment.

Attribute X is said to be preferentially independent of attribute Y if preferences for levels of X do not depend on the level of Y. Mutual preferential independence where all subsets of the attributes are preferentially independent complements is a necessary condition for using an additive value function to measure the value of projects.

To use a common example, suppose that when ordering a meal at a restaurant you are concerned about two attributes: Suppose you prefer beef to fish regardless of the color of wine you drink, in which case your preferences for food may be preferentially independent of wine.

However, suppose you prefer white wine with fish and red wine with beef. Then your preferences for wine depends on the food you order, so wine is not preferentially independent of food.

As the example shows, one attribute may be preferentially independent of another without that other attribute being preferentially independent of it. That's why mutual preferential independence is needed.

A subset of the attributes X1, X2, If this property holds for all levels x1, x2, For example, suppose there are three attributes, X1, X2X3, and suppose x1 and x'1 are two levels for X1; x2 and x'2 are two levels for X2, and; x3 and x'3 are two levels for X3. Demonstrating that each pair of attributes is preferentially independent of its complement means finding that preferences for: Demonstrating mutual preferential independence would appear to require showing that each individual attribute is preferentially independent of its complement, each pair of attributes is preferentially independent of its compliment, then each triplet, and so forth, which is a lot of assessments.

However, as it has been proven that if Xi and Xj can be shown to be preference independent of the remaining attributes for any fixed attribute Xi and for all other Xj attributes, then mutual preferential independence must hold.

Mutual preference independence is important because it is a necessary but not sufficient condition for the existence of an additive value function applicable when there is no uncertainty over the levels of attributes: As an example of what happens when preferential independence is violated, suppose you are at a restaurant and want to select a meal with a glass of wine.

As demonstrated above, your preferences for wines may not be preferentially independent of your preferences for main dishes. Thus, the combination of your favorite wine from the wine list with your favorite entree from the menu won't necessarily result in the dinner meal you'd like best.

Note that preferential independence does not require statistical independence or causal independence. Mutual preferential independence can hold even when performance against different criteria is highly correlated, provided that the criteria express separate aspects of value e.

Uncertainty, Probability and Money. was the basis for the further development of the issue of decision making under uncertainty in Keynes’s Treatise on Probability. (): ) entrepreneurs form two kinds of expectations in order to make their business decisions. The first, called short-term expectations, relate to the price of. Understanding the Dynamics of Decision-making and Choice: A scoping study of key psychosocial theories to • An examination of what is understood about some specific decision-making situations: making decisions on behalf of someone else; shared decision- include formal logic, probability theory, and decision theory. Descriptive. Some conditions in which a business decision is made using subjective probability (educated guess) would include estimating the probability that a person may win drawing or estimating the probability that the company .

Thus, a project that reduces pollution from company operation might simultaneously improve the health of local populations and be good for the environment. In that case, the project would produce both human health value and environmental value.

Because they are separate types of value human health and environmental health are preferentially independentthere is no double counting when adding the two types of value. Present value is computed via a discount rate and the net present value formula.

PRINCE2 Similar to PMBOKPRINCE2 is a process-based, project management methodology based on the application of best-practices such as continued business justification, learning from experience, defining roles and responsibilities, managing by stages, managing by exception, and focusing on products and tailored to suit the project environment.

PRINCE2 was originally developed by the government of the United Kingdom and is now widely used there, as well as internationally and in the private sector especially in information technology IT environments.

The term is also used to refer to the training and accreditation of authorized practitioners of the methodology who undertake accredited qualifications to obtain certification. The process of assigning priorities to things or tasks for the purpose of deciding how best to allocate time, money, or other limited resources.

Prioritization involves ranking items into an ordered list. The list indicates the order or preference for choosing the items, assuming that constraints or limits make it impossible to freely choose all items. In the case of projectstime, money, and resource constraints make prioritization necessary.

Project prioritization involves displaying in a list the order in which projects would be added or removed as constraints governing what can be accomplished are relaxed or tightened.

Prioritization is generally utilized in the domain of portfolio management as a methodology that utilizes one or more quantitative or qualitative metrics to generate a rank order of projects Importantly, as described in the paper on mathematical methodsthe ratio of project benefit or value to project cost can in some cases be used as a priority measure for ranking projects.

When independent projects are ranked using such a measure, selecting projects in rank order until the budget is consumed will approximately identify the projects that generate the greatest total benefit value for the available budget. The concept of project prioritization is less helpful in situations where there are interdependencies among projects and when there are multiple constraints that limit the set of projects that can be conducted e.

In such circumstances, it is generally still possible to show as a list the order in which projects would be added or deleted from the project portfolio, but the list would change depending on the particular constraint that is adjusted.

Also, the list will not be a strict ranking. For example, as the budget is increased, a project that is initially added might be dropped to accommodate a larger project with a higher benefit-to-cost ratio see the discussion on the efficient frontiers vs.presents the expected utility approach to decision making under probabilities, and belief functions.

A proposition for decision making under ambiguity is developed in Section 5. Also, the ﬁswitchingﬂ behavior, as observed by EH, is discussed in Section 5.

Section 6 validates the proposition using the EH empirical results. Identify the conditions in which individuals are most likely to use intuition in decision making.

A fuzzy concept is a concept of which the boundaries of application can vary considerably according to context or conditions, instead of being fixed once and for all. This means the concept is vague in some way, lacking a fixed, precise meaning, without however being unclear or meaningless altogether.

It has a definite meaning, which can be made more precise only through further elaboration. 4 Decision Making Under Risk (or Decision Making with Probabilities) judgment experience. Subjective Probability Determined by an estimate based on personal belief.
