1.

1 point

analog

constrained

2.

1 point

Inputs to a quantitative model

are a trivial part of the problem solving process.

are uncertain for a stochastic model

are uncontrollable for the decision variables.

must all be deterministic if the problem is to have a solution

3.

1 point

Problem definition

includes specific objectives and operating contraints

must occur prior to the quantitative analysis process

must involve the analyst and the user of the results

each of the above is true

4.

1 point

The field of management science

concentrates on the use of quantitative methods to assist in decision making

approaches decision making rationally, with techniques based on the scientific method.

is another name for decision science and for operations research.

each of the above is true.

5.

1 point

In a multicriteria decision problem

it is impossible to select a single decision alternative.

the decision maker must evaluate each alternative with respect to each criterion

successive decisions must be made over time

each of the above is true.

6.

1 point

break-even point.

marginal volume

marginal cost

profit mix.

7.

1 point

When the value of the output cannot be determined even if the value of the controllable input is known, the model is

analog

digital

stochastic

deterministic

8.

1 point

Decision criteria

are the choices faced by the decision maker

are the problems faced by the decision maker.

are the ways to evaluate the choices faced by the decision maker.

must be unique for a problem.

9.

1 point

Decision alternatives

should be identified before decision criteria are established.

are limited to quantitative solutions.

are evaluated as a part of the problem definition stage.

are best generated by brain-storming.

10.

1 point

The first step in problem solving is:

determination fo the correct analytical solution procedure

definition of decision variables

the identification of a difference between the actual and desired state of affairs

implementation

11.

1 point

a mathematical model.

a qualitative model.

12.

1 point

Management science and operations research both involve

qualitative managerial skills

quantitative approaches to decision making.

operational management skills

scientific research as opposed to applications

13.

1 point

George Dantizig is important in the history of management science because he developed

14.

1 point

Identification and definition of a problem

cannot be done until alternatives are proposed.

is the first step of decision making.

is the final step of problem solving.

requires consideration of multiple criteria.
