Study Notes
- Linear Optimization Model (Linear Programming Model) represents objectives and constraints using linear relationships to find the best possible outcome.
- Decision Variables: Controllable variables that represent choices to optimize the objective function.
- Objective Function: This is a linear mathematical expression that represents the goal to maximize or minimize.
- Constraints: Linear inequalities or equations that limit the values of decision variables, representing restrictions.
- Parameters: Fixed numerical values like cost coefficients and resource limits that influence the model.
- Non-Negativity Restrictions: Requires decision variables to be greater than or equal to zero.
- Graphical Method: Solves linear optimization problems with two decision variables by plotting constraints to find the optimal solution.
- Simplex Method: An algebraic procedure for solving larger linear optimization problems by moving from one feasible solution to an optimal one.
- Feasible Region: The set of all possible solutions that satisfy all constraints.
- Decision Theory: A systematic approach to making decisions under uncertainty and risk by evaluating choices.
- Deterministic Decision: A decision made under complete certainty, where outcomes are known.
- Decision Making Under Uncertainty: Decisions are made when the probabilities of potential outcomes are not precisely known.
- Decision Making Under Risk: Decisions are made when the probabilities of potential outcomes are known or can be reasonably estimated.
- Expected Monetary Value (EMV): Weighted average of potential payoffs, with weights being the probabilities of outcomes.
- Expected Value of Perfect Information (EVPI): The maximum amount a decision maker would pay for perfect information.
- Minimizing Expected Loss: A decision criterion focused on selecting the alternative with the smallest average loss.
- Maximin: A pessimistic decision criterion that maximizes the minimum possible payoff.
- Maximax: An optimistic decision criterion that maximizes the maximum possible payoff.
- Expected Utility: Combines probabilities of outcomes with the decision maker's preferences to determine the best action.
- Satisficing: Choosing a satisfactory solution rather than the absolute optimum.
- Decision Tree: A visual tool that represents decisions, chance events, and outcomes in a tree structure.
- Decision Node: Represents a choice that needs to be made in a decision tree.
- Chance Node: Represents an uncertain event with multiple outcomes, each with a probability.
- Alternative Branches: Lines from a decision node, representing possible choices.
- Endpoint Node: A terminal point in a decision tree, representing a final outcome.
