Capacity Planning Capacity is the upper limit or ceiling on the
load that an operating unit can handle. Capacity also includes
Equipment ( 설비 ) Space ( 공간 ) Employee skills ( 작업능력 )
The basic questions in capacity handling are: What kind of capacity is needed? ( 어떤 종류 ) How much is needed? ( 얼마나 ) When is it needed? ( 언제 )
![Page 9: Introduction to Operations Management Ch. 5. Strategic Capacity Planning for Products and Services Hansoo Kim ( 金翰秀 ) Dept. of Management Information Systems,](https://reader035.vdocuments.us/reader035/viewer/2022062304/56649f035503460f94c17279/html5/thumbnails/9.jpg)
Importance of Capacity Decisions
1. Impacts ability to meet future demands
2. Affects operating costs3. Major determinant of initial costs4. Involves long-term commitment5. Affects competitiveness6. Affects ease of management7. Globalization adds complexity8. Impacts long range planning
![Page 10: Introduction to Operations Management Ch. 5. Strategic Capacity Planning for Products and Services Hansoo Kim ( 金翰秀 ) Dept. of Management Information Systems,](https://reader035.vdocuments.us/reader035/viewer/2022062304/56649f035503460f94c17279/html5/thumbnails/10.jpg)
Capacity Design capacity
Maximum output rate or service capacity an operation, process, or facility is designed for
Effective capacity Design capacity minus allowances such
as personal time, maintenance, and scrap Actual output
Rate of output actually achieved--cannot exceed effective capacity.
![Page 11: Introduction to Operations Management Ch. 5. Strategic Capacity Planning for Products and Services Hansoo Kim ( 金翰秀 ) Dept. of Management Information Systems,](https://reader035.vdocuments.us/reader035/viewer/2022062304/56649f035503460f94c17279/html5/thumbnails/11.jpg)
Efficiency( 효율 ) and Utilization(가동률 )
Actual outputEfficiency =
Effective capacity
Actual outputUtilization =
Design capacity
Both measures expressed as percentages
Design capacity = 50 trucks/day
Effective capacity = 40 trucks/day
Actual output = 36 units/day

Key Decisions of Capacity Planning
1.Amount of capacity needed• Capacity cushion = (100% - Utilization)
2.Timing of changes3.Need to maintain balance4.Extent of flexibility of facilities
Capacity cushion – extra demand intended to offset uncertainty
![Page 14: Introduction to Operations Management Ch. 5. Strategic Capacity Planning for Products and Services Hansoo Kim ( 金翰秀 ) Dept. of Management Information Systems,](https://reader035.vdocuments.us/reader035/viewer/2022062304/56649f035503460f94c17279/html5/thumbnails/14.jpg)
Steps for Capacity Planning
1.Estimate future capacity requirements2.Evaluate existing capacity3.Identify alternatives4.Conduct financial analysis5.Assess key qualitative issues6.Select one alternative7.Implement alternative chosen8.Monitor results
![Page 15: Introduction to Operations Management Ch. 5. Strategic Capacity Planning for Products and Services Hansoo Kim ( 金翰秀 ) Dept. of Management Information Systems,](https://reader035.vdocuments.us/reader035/viewer/2022062304/56649f035503460f94c17279/html5/thumbnails/15.jpg)
Forecasting Capacity Requirements
Long-term vs. short-term capacity needs Long-term relates to overall level of
capacity such as facility size, trends, and cycles
Short-term relates to variations from seasonal, random, and irregular fluctuations in demand
Figure5-1 Common demand patterns

Developing Capacity Alternatives
1.Design flexibility into systems2.Take stage of life cycle into account
3.Take a “big picture” approach to capacity changes (not to be sub-optimal)
4.Prepare to deal with capacity “chunks”
5.Attempt to smooth out capacity requirements
6.Identify the optimal operating level

Economies of Scale
Economies of scale If the output rate is less than
the optimal level, increasing output rate results in decreasing average unit costs
Diseconomies of scale If the output rate is more than
the optimal level, increasing the output rate results in increasing average unit costs

Example 3 Adding a new line of pies, which will require leasing
new equipment for a monthly payment of $6,000. Variable costs would be $2.00 per pie, and pies would retail for $7.00 each.
1. How many pies must be sold in order to break even?2. What would the profit (loss) be if 1,000 pies are made and
sold in a month?3. How many pies must be sold to realize a profit of $4,000?4. If 2,000 can be sold, and a profit target is $5,000, what
price should be charged per pie?SOLUTION

Decision Process
1. Identify the problem2. Specify objectives and criteria for a solution3. Develop suitable alternatives4. Analyze and compare alternatives5. Select the best alternative6. Implement the solution7. Monitor to see that the desired result is
achieved
![Page 31: Introduction to Operations Management Ch. 5. Strategic Capacity Planning for Products and Services Hansoo Kim ( 金翰秀 ) Dept. of Management Information Systems,](https://reader035.vdocuments.us/reader035/viewer/2022062304/56649f035503460f94c17279/html5/thumbnails/31.jpg)
Certainty - Environment in which relevant parameters have known values
Risk - Environment in which certain future events have probable outcomes
Uncertainty - Environment in which it is impossible to assess the likelihood of various future events
Decision EnvironmentsDecision Environments
1. Profit per unit is $5. You have an order for 200 units. How much profit will you make? (This is an example of certainty since unit profits and total demand are known.)
2. Profit is $5 per unit. Based on previous experience, there is a 50 percent chance of an order for 100 units and a 50 percent chance of an order for 200 units. What is expected profit? (This is an example of risk since demand outcomes are probabilistic.)
3. Profit is $5 per unit. The probabilities of potential demands are unknown. (This is an example of uncertainty.)
![Page 32: Introduction to Operations Management Ch. 5. Strategic Capacity Planning for Products and Services Hansoo Kim ( 金翰秀 ) Dept. of Management Information Systems,](https://reader035.vdocuments.us/reader035/viewer/2022062304/56649f035503460f94c17279/html5/thumbnails/32.jpg)
Decision Making under Certainty
Solution:Choose the alternative with the highest payoffIf demand is low, take “small facility” alternativeIf demand is moderate, take “Medium facility” alternativeIf demand is high, take “Large facility” alternative
Payoff tablePayoff table
![Page 33: Introduction to Operations Management Ch. 5. Strategic Capacity Planning for Products and Services Hansoo Kim ( 金翰秀 ) Dept. of Management Information Systems,](https://reader035.vdocuments.us/reader035/viewer/2022062304/56649f035503460f94c17279/html5/thumbnails/33.jpg)
Maximin - Choose the alternative with the best of the worst possible payoffs
Maximax - Choose the alternative with the best possible payoff
Laplace - Choose the alternative with the best average payoff of any of the alternatives
Minimax Regret - Choose the alternative that has the least of the worst regrets
Decision Making under Uncertainty
![Page 34: Introduction to Operations Management Ch. 5. Strategic Capacity Planning for Products and Services Hansoo Kim ( 金翰秀 ) Dept. of Management Information Systems,](https://reader035.vdocuments.us/reader035/viewer/2022062304/56649f035503460f94c17279/html5/thumbnails/34.jpg)
Decision Making under Uncertainty
(a)Maximin
(b) Maximax
(c) Laplace For the Laplace criterion, first find the row totals, and
then divide each of those amounts by the number of states of nature (three in this case).
(d) Minimax Regret (Opportunity Losses)
![Page 35: Introduction to Operations Management Ch. 5. Strategic Capacity Planning for Products and Services Hansoo Kim ( 金翰秀 ) Dept. of Management Information Systems,](https://reader035.vdocuments.us/reader035/viewer/2022062304/56649f035503460f94c17279/html5/thumbnails/35.jpg)
Decision Making Under Risk Risk: The probability of occurrence for each
state of nature is known Risk lies between the extremes of uncertainty
and certainty Expected monetary value (EMV) criterion:
The best expected value among alternatives Determine the expected payoff of each alternative,
and choose the alternative with the best expected payoffWhen demand
probabilities are distributed as followslow = .30, moderate = .50, and high = .20.

Decision Tree
Decision tree: a Schematic representation of the available alternatives and their possible consequences.
![Page 37: Introduction to Operations Management Ch. 5. Strategic Capacity Planning for Products and Services Hansoo Kim ( 金翰秀 ) Dept. of Management Information Systems,](https://reader035.vdocuments.us/reader035/viewer/2022062304/56649f035503460f94c17279/html5/thumbnails/37.jpg)
Example A manager must decide on the size of a video arcade to
construct. The manager has narrowed the choices to two: large or small. Information has been collected on payoffs, and a decision tree has been constructed. Analyze the decision tree and determine which initial alternative (build small or build large) should be chosen in order to maximize expected monetary value.

Expected Value of Perfect Information (EVPI)
Expected value of perfect information: the difference between the expected payoff under certainty and the expected payoff under risk
Expected value ofperfect information
Expected payoffunder certainty
Expected payoffunder risk= -

Sensitivity Analysis Sensitivity Analysis: Determining the range of
probability for which an alternative has the best expected payoff
Useful for decision makers to have some indication of how sensitive the choice of an alternative is to changes in one or more of these values
