wherein variables are binary. (0 or 1)
Pure BIP model - ANSWER - A BIP model wherein the variables are restricted to binary
variables
, Mixed BIP model - ANSWER - A BIP model wherein only some variables are restricted
to binary variables
Non-Linear Programming? - ANSWER - the model is a linear programming model
except for having at least one nonlinear formula for an output cell (such as the objective
cell)
Decision Analysis? - ANSWER - It provides a framework that business leaders could
use whenever outcomes to situations become uncertain.
Decision Maker - ANSWER - individual/group responsible for the decision making
Alternatives - ANSWER - A set of options that the decision maker could choose from.
State of nature - ANSWER - A possible situation that could arise due to random factors
that aren't controlled by the decision maker
Payoff - ANSWER - The quantitative measure to the consequences of each outcome.
Prior Probability - ANSWER - The estimated probabilities of the states of nature prior to
obtaining additional information through a test or survey.
Maximax Criterion - ANSWER - This criterion gives an opportunity for the best possible
outcome (the largest payoff in the entire payoff table) to occur
Maximin Criterion - ANSWER - This criterion provides the best possible protection
against being unlucky
Maximum likelihood Criterion - ANSWER - Through basing our decision on the
assumption that the most likely state of nature will occur, there is a higher chance of
better outcome.
Bayes' Decision Rule - ANSWER - decision rule says to choose the alternative with the
largest expected payoff.
Decision tree - ANSWER - Illustration for decision analysis
