비경제적 가치

Value( 가치 ) : Ratio of quality to price paid. Competitive “Happiness” is being able to increase quality and reduce price while maintaining or improving profit margins<Jacobs, Chase, “Operations and Supply Management, 2008>

경제적 가치의 의미

Cost ( 비용 )

Profit ( 수익 )

Revenue( 수입 )

경제적 수익의 발생은 기업의 지속성을 가능하게 한다 .

수익을 내지 못하는 기업은 결국 파산

Profit = Revenue - Cost

비즈니스 : “ 가치” 를 만들어 내는 Framework

• 가치는 가치 판단 기준에 의해 평가될 수 있다 .• 같은 사건에 대해서 , 판단 기준에 따라 좋은

가치를 유의한 가치를 갖을수도 있고 , 그렇지 않을 수도 있다 .

• 그렇기 때문에 가치경영은 어떤 가치기준을 가지고 그 가치를 극대화 하는가에 따라 그 내용과 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 ?)

16

Example: Product Mix

Smart furnitureSmart 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 makea 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 furnitureSmart 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 profitsto make maximum profits?

$10.00 $20.00

Wood: 5 unitsSteel: 3 unitsNail: 20 units

Wood: 10 unitsSteel: 10 unitsNail: 10 units

Wood: 1000 units

Steel: 300 units

Nail: 1000 units

3 Key Things in Studying OM

1. Understanding Problem ( 问题 상황에 대한 理解 ) 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 ↓)

2. Developing Proper Model ( 적절한 모델 개발 ) Let’s Make it Simple but Meaningful! Trade off between Reality and Problem solving Finding good model is important!

3. Finding Solution Techniques ( 문제 해결 방법 찾기 ) Problem solving techniques, and analysis Efficient solution vs. Effective solution

19

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 We need to find a way to decide number of chairs and tables to chairs and tables to maximize total profitmaximize total profit

20

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

resultSimple Model => Easy to analysis but worse result

We should We should develop proper develop proper modelmodel to solve the problem!!! to solve the problem!!!

21

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

22

3. Finding Solution Techniques( 문제해결 방법 찾기 )

For the example, 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 We need to know how to solve the problem problem efficientlyefficiently or or effectivelyeffectively

Max Z= 10 X1 + 20 X2S.t. 5 X1 + 10 X2 1000 3 X1 + 10 X2 300 20X1 + 10 X2 1000 X1 0, and X2 0

23

To be OM Expert !!!

UnderstandingProblem

OM EXPERT!!

24

Purpose of the class By: introducing basic knowledge of operations

management and control with various quantitative and qualitative techniques Types of OM activities Types of problems Types of solution techniques

To: Improve the abilities to analyze the problem occurred in OM fields, to present the efficient and effective solutions for

the problems in the modern production and logistics systems

25

After finishing this course… YOU CAN

The most important effects You can talk with other OM people You can identify the types of problem in OM You can understand the basic principles of

problem-solving techniques.

Other important effects You can become an Expert having “Intuition”

Knowledge, Responsibility, and Professionalism

About Class (continued) 3 Absences -> “F” : No Question! 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 assignment.

Individual Assignments: Students will need to turn in the homework each week.

Team Project: Students will work as a team of 4 or 5. Team members will work on the cases together and will take turns to present their work. Each team is required to submit a written report prior to the assigned class.

The lecture notes and other materials will be uploaded on the class homepage. Before attending class, please check class homepage!!!

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