Value(가치) : Ratio of quality to price paid. Competitive

price while maintaining or improving profit margins

경제적 가치의 의미
Profit (수익)

(수입)
경제적 수익의 발생은 기업의 지속성을 가능하게 한다.
수익을 내지 못하는 기업은 결국 파산
Cost (비용)
Profit = Revenue - Cost
비즈니스: “가치”를 만들어 내는 Framework
•
•
•
가치는 가치 판단 기준에 의해 평가될 수 있다.
같은 사건에 대해서, 판단 기준에 따라 좋은 가
치를 유의한 가치를 갖을수도 있고, 그렇지 않
을 수도 있다.
그렇기 때문에 가치경영은 어떤 가치기준을 가
지고 그 가치를 극대화 하는가에 따라 그 내용
과 결과가 달라질 수 있다.

기업활동을 통해 드러낼 수 있는 올바른 “가치”관
직업과 비즈니스의 궁극적인 목적은 단순히 경제적인 필요를 채우거나,
자아실현을 위한 것이 아니라, 그것을 뛰어넘어 인류의 진정한 가치를
드러내는 행위를 통하여 인류사회에 공헌하기 위한 것이다!

What is OM(生产管理)?
 Operations Management (OM)
 the set of activities that creates value(价值 )
in the form of goods(商品) and services(服务)
by transforming inputs into outputs
 What activities (어떤 活动 이 있는가)?
 How to evaluate (어떻게 评价 할 것인가)?
We need evaluation measures – Productivity!!
(生产性)
What are the better activities?
(어떤 活动을 어떻게 하면 生产性이 좋을까?)

Example: Product Mix
Smart furniture company manufactures two products, Chair and Table.
The profit of selling a Chair is $10.00 and that of Table is $20.00. To make
a Chair, it requires 5 units of wood, 3 units of steel and 20 units of nails
(螺丝), and to make a Table, it requires 10 units of wood, 10 units of steel,
and 10 units of nail. Suppose that the Smart furniture has 1000 units of
wood, 300 units of steel, and 1000 units of nail, how many Chairs
and Tables should be produced to make maximum profits?
Wood: 1000 units
Wood: 5 units
Steel: 3 units
Nail: 20 units
$10.00
Wood: 10 units
Steel: 10 units
Nail: 10 units
$20.00
Steel: 300 units
Nail: 1000 units

3 Key Things in Studying OM
1.
Understanding Problem (问题 상황에 대한



2.
)
What kind of problems are there in an Operation?
Is there any way to control (or decision making)?
What is the evaluation measure? (profit ↑ cost ↓)
Developing Proper Model (적절한 모델 개발)

3.
理解
Let’s Make it Simple but Meaningful!
Trade off between Reality and Problem solving
Finding good model is important!
Finding Solution Techniques (문제 해결 방법 찾기)


Problem solving techniques, and analysis
Efficient solution vs. Effective solution
18
1. Understanding Problem
(문제에 대한 이해)
 From the example,
Need a decision rule for product mix
 How many chairs? How many tables?
 Why it is important?
 Depending on the result of product mix, total profit are
different!!
 Number of chairs and tables can be controlled
 Evaluation measure
 Profit maximization

 We need to find a way to decide number of chairs
and tables to maximize total profit
19
2. Developing Proper Model
(적절한 모델 개발)
 From the example,
 Make it simple but meaningful
 Selling price depends on its selling unit.
 Assumption: No discount!
 Why?
Realistic Model => Difficult to analysis but better result
Simple Model => Easy to analysis but worse result
 We should develop proper model to
solve the problem!!!
20
Mathematical Model
 Decision Variables:

X1:= Number of Chairs, X2:=Number of Tables
 Objective Function:

Max Z= 10 X1 + 20 X2
 Conditions (or Constraints)

S.t. 5 X1 + 10 X2  1000
3 X1 + 10 X2  300
20X1 + 10 X2  1000
X1  0, and X2  0
21
3. Finding Solution Techniques
(문제해결 방법 찾기)
 For the example,
Max Z= 10 X1 + 20 X2
S.t. 5 X1 + 10 X2  1000
3 X1 + 10 X2  300
20X1 + 10 X2  1000
X1  0, and X2  0
 How to solve the problem?
 Solution techniques
 Two types of solution techniques
 Effective (效果的) (or Optimal, Exact) Solution
 The best solution but difficult to find it
 Efficient (效率的) Solution
 Not best solution but easier to find it

We need to know how to solve the problem
efficiently or effectively

3 No Homework -> “D or F” : No Question!
Reading Assignments: Students should read the reading
assignments before they come to the class. Class discussion will
proceed with the assumption that students have read the

homepage!!!
No late homework. If you have proper excuse for late
homework, you can turn in the homework only after talking with
29
the instructor.
