When? Where? Why? How? By whom? Add a footer TREY research 23 Decision-Making Disciplines Behavioral and Scientific Behavioral: law, political science, psychology Scientific: computer science, decision analysis, economics, engineering, the hard sciences (e.g., biology, chemistry, physics), management science/operations research, mathematics, and statistics Each discipline has its own set of assumptions and each contributes a unique, valid view of how people make decisions Add a footer TREY research 24 Decision-Making Disciplines Better decisions Tradeoff: accuracy versus speed Fast decision may be damaging Many areas suffer from fast decisions Effectiveness versus Efficiency Effectiveness → “goodness” “accuracy” Efficiency → “speed” “less resources” A fine balance is what is needed!

Add a footer TREY research 29 Simon’s Decision-Making Process TREY research Decision Making: Intelligence Phase Scan the environment, either intermittently or continuously Identify problem situations or opportunities Monitor the results of the implementation Problem is the difference between what people desire (or expect) and what is actually occurring Symptom versus Problem Timely identification of opportunities is as important as identification of problems TREY research Decision Making: Intelligence Phase Phase 1 Potential issues in data/information collection and estimation Lack of data Cost of data collection Inaccurate and/or imprecise data Data estimation is often subjective Data may be insecure Key data may be qualitative Data change over time (time-dependence) Add a footer TREY research 32 Decision Making: Intelligence Phase Problem Classification Classification of problems according to the degree of structuredness Problem Decomposition Often solving the simpler subproblems may help in solving a complex problem. Information/data can improve the structuredness of a problem situation Problem Ownership Outcome of intelligence phase → A Formal Problem Statement TREY research Decision Making:The Design Phase Phase 2 Finding/developing and analyzing possible courses of actions A model of the decision-making problem is constructed, tested, and validated Modeling: conceptualizing a problem and abstracting it into a quantitative and/or qualitative form (i.e., using symbols/variables) Abstraction: making assumptions for simplification Tradeoff (cost/benefit): more or less abstraction Modeling: both an art and a science Add a footer TREY research 34 Decision Making:The Design Phase Phase 2 Selection of a Principle of Choice It is a criterion that describes the acceptability of a solution approach Reflection of decision-making objective(s) In a model, it is the result variable Choosing and validating against High-risk versus low-risk Optimize versus satisfice Criterion is not a constraint! See Technology Insight 2.1 Add a footer TREY research 35 Decision Making:The Design Phase Phase 2 Normative models (= optimization) the chosen alternative is demonstrably the best of all possible alternatives Assumptions of rational decision makers Humans are economic beings whose objective is to maximize the attainment of goals For a decision-making situation, all alternative courses of action and consequences are known Decision makers have an order or preference that enables them to rank the desirability of all consequences Add a footer TREY research 36 Decision Making: The Design Phase ▸ Heuristic models (= suboptimization) ▹ The chosen alternative is the best of only a subset of possible alternatives ▹ Often, it is not feasible to optimize realistic (size/complexity) problems ▹ Suboptimization may also help relax unrealistic assumptions in models ▹ Help reach a good enough solution faster ▹ The rule of thumb ▹ An experienced trial and error TREY research 37 Decision Making:The Design Phase Phase 2 Descriptive models Describe things as they are or as they are believed to be (mathematically based) They do not provide a solution but information that may lead to a solution Simulation - most common descriptive modeling method (mathematical depiction of systems in a computer environment) Allows experimentation with the descriptive model of a system Add a footer TREY research 38 Decision Making: The Design Phase Good Enough, or Satisficing “something less than the best” A form of suboptimization Seeking to achieve a desired level of performance as opposed to the “best” Benefit: time saving Simon’s idea of bounded rationality TREY research Decision Making:The Design Phase Phase 2 Risk Lack of precise knowledge (uncertainty) Risk can be measured with probability Scenario (what-if case) A statement of assumptions about the operating environment (variables) of a particular system at a given time Possible scenarios: best, worst, most likely, average (and custom intervals) Add a footer TREY research 40 Decision Making:TheChoice Phase Phase 3 The actual decision and the commitment to follow a certain course of action are made here The boundary between the design and choice is often unclear (partially overlapping phases) Generate alternatives while performing evaluations Includes the search, evaluation, and recommendation of an appropriate solution to the model Solving the model versus solving the problem!
