Study Notes
Management Science & Decision Making
- Management science involves a systematic approach to problem-solving.
- Teams are typically involved in applying this approach.
- This approach emphasizes the use of mathematical models, statistical methods, and quantitative tools.
Steps of Modeling
- Formulate the problem: Clearly define the problem that needs to be addressed.
- Construct a model: Develop a representation of the problem using mathematical or other formal methods.
- Test the model: Evaluate the model's accuracy and validity.
- Derive a solution from the model: Use the model to determine the best course of action or solution to the problem.
Decision Making Under Uncertainty: Game Theory
- Payoff (Benefit) Table - Decision Matrix: A tool used to analyze decisions when the outcomes are uncertain.
- The table lists different possible actions (decisions) and their corresponding payoffs for each possible state of nature (event).
Example: Production Level Decision
- Problem: Maximize profit in producing X and Y products.
- Constraints: Limited factory workers (3 machinists and 2 assemblers), each working 40 hours a week.
- Decision Matrix: Rows represent different production plans (products I, II, III, Do Nothing), columns represent different demand levels, and cells contain the profit for each combination.
Equally Likely (Laplace) Criterion
- This criterion assumes that all states of nature are equally likely.
- Step 1: Find the minimum payoff for each row.
- Step 2: Select the row with the highest minimum payoff.
- In this example: Product II has the highest minimum payoff (200$) and is considered the best choice under the equally likely criterion.
Decision Making
- It is a process of selecting a course of action from among several alternatives.
- The process of decision-making involves identifying the problem, gathering information, evaluating alternative solutions, choosing the best solution, and implementing the decision.
- Decision-making can be complex, and there is no one-size-fits-all approach. The best approach will depend on the specific situation.
