Reasons of intuitive decision-making Exercise and meaning of decision-making • unknown principle problem • unknown ambitions and criteria • absence of necessary information • absence time • leaving out of systematic methods
Models of decision-making • Rational economic model • optimization principle • Administrative model • satisfaction principle
Types of decision-making problems and situations • Right and wrong structure problems • Decision-making in certainty, risk and uncertainty • Static and dynamic decision-making • Decision-making with and without conflict
Bad structured problem • The global crisis continues find the way to be profitable. • Find new product to our customers. • Excercise • Here you have a sheet of a paper. Do a hole to it and pass through the hole without total destroing the paper.

Information for decision-making • Primary source • Secondary source • Provision of efficient collection of information • setting range of information • right interpretation of information
Rational process of resolution of decision-making problems • Analysis and formulation of a problem • Assessment criteria appreciation • Production variants solving • Appreciation of variants and choice of the most suitable • Realization of acceptable variant • Controlling results of realized variant • Identification of a decision-making problem
Decision-making in risk and uncertainty Decision-making´s matrix
Rules of decision-making in risk • rule of expected mean value • Ej = Uji*pi • rule of expected mean value of variance • D(z) = (zi – E(z))2*pi
Rules of decision-making in uncertainty • Rule of minimax • Rule of maximax • Laplace´s rule • Hurwitz´s rule • Savage´s rule
Selecting the best alternative The company wants to introduce a new product. The presumptive revenues are depended on time how long will be the company in the market alone. With the rules for deciding in condition of uncertainty choose the best from the three variants.
