Exam 1: Introduction

Three production processes-A,B,and C-have the following cost structure: ​ ​ a.What is the most economical process for a volume of 8,000 units? b.How many units per year must be sold with each process to have annual profits of $50,000 if the selling price is $6.95 per unit? c.What is the breakeven volume for each process?

Problem solving encompasses both the identification of a problem and the action to resolve it.

The feasible solution is the best solution possible for a mathematical model.

Decision criteria

The last step in any problem-solving process is to choose the correct alternative among those available.

There is a fixed cost of $50,000 to start a production process.Once the process has begun,the variable cost per unit is $25.The revenue per unit is projected to be $45. a.Write an expression for total cost. b.Write an expression for total revenue. c.Write an expression for total profit. d.Find the breakeven point.

Management science and operations research both involve

A model that uses a system of symbols or expressions to represent a problem is called a(n)______ model.

The volume that results in total revenue being equal to total cost is known as the

The set of decision alternatives

The optimal solution to a model is one in which known,specific values provide the best output.

A valid reason for using a quantitative approach to the decision-making process is when

The breakeven point is the point at which the volume of output produced is the result of total revenue equaling total cost.

An author has received an advance against royalties of $10,000.The royalty rate is $1.00 for every book sold in the United States,and $1.35 for every book sold outside the United States.Define variables for this problem and write an expression that could be used to calculate the number of books to be sold to cover the advance.

The decision-making process includes implementation and subsequent evaluation of the decision.

The field of management science

Decision variables in a production process are those that cannot be controlled by the manager.

To identify the choice that provides the highest profit and also uses the fewest employees,we apply a single-criterion decision process.

A thermometer is an example of a model that does not have the same physical appearance as that which is being modeled; thus,it is a(n)

Which of the following is NOT one of the commonly used names for the body of knowledge involving quantitative approaches to decision making?
