    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.

    Determinants of Effective Capacity

    FACILITIES

    The design of facilities, including size and provisionfor expansion, is key.

    Locational factors, such as transportation costs,

    distance to market, labor supply, energy sources and

    room for expansion are also important.

    Likewise, layout of the work area andenvironmental factors also play a significant role.

    PRODUCT AND SERVICE FACTORS

    Product and service design can have a tremendousinfluence on capacity.

    The more uniform the output, the more

    opportunities there are for standardization of

    methods and materials.PROCESS FACTORS

    The quantity capability of a process is an obvious

    determinant of capacity but subtle determinant isthe influence of output quality.

    Process improvement that increase quality and

    productivity can result in increased capacity.

    HUMAN FACTORS

    The tasks that make up a job, the variety of activities

    involved, also the training, skill and experiencerequired to perform a job all have an impact on the

    potential and actual output.

    Employee motivation has a very basic relationship tocapacity , as do absenteeism.

    POLICY FACTORS

    Management policy can affect capacity by allowingor not allowing capacity options such as overtime or

    second or third shifts.

    OPERATIONAL FACTORS

    Inventory stocking decisions, late deliveries,

    purchasing requirements, acceptability of purchasedmaterials, quality inspection and control procedures

    also have an impact on effective capacity.

    SUPPLY CHAIN FACTORS It must be taken into account in capacity planning ifsubstantial capacity changes are involved.

    EXTERNAL FACTORS Product standards , especially minimum quality andperformance standards, can restrict managements

    options for increasing capacity.

    Strategy Formulation

    An organization typically its base its capacitystrategy on assumption and predictions about

    long term demand patterns, technological

    changes , and the behavior of its competitors.

    Key decisions of capacity planning The amount of capacity needed

    The timing of changes The need to maintain balance throughout the system

    The extent of flexibility of facilities and the

    workforce.

    Deciding on the amount capacity

    involves consideration of expected

    demand and capacity cost.

    Capacity cushion which is an amount

    capacity in excess of expected demand

    when there is some uncertainty about

    demand. the greater the degree of demand uncertainty , the greater

    the amount cushion used.

    Steps in the Capacity Planning Process Estimate future capacity requirement

    Evaluate existing capacity and facilities and identify

    gaps.

    Identify alternative for meeting requirements

    Conduct financial analyses of each alternative Assess key qualitative issues for each alternative

    Select the alternative to pursue that will be bests in

    long term Implement the selected alternative

    The Challenge of Planning Service

    CapacityThree Important Factors in planning service capacity

    The need to be near customers

    Convenience for customers is often an

    important aspects of services. Generally, a

    service must be located near customer.

    The inability to store service

    Speed of the delivery, or customers waiting time

    become a major concern in a service capacityplanning .

    The degree of volatility

    Demand volatility presents problem for capacity

    planners. Demand volatility tend to be higher forservices than goods, not only in timing of demand,

    But also in amount of time required to the service

    individual customers.

    Make Or Buy

    Once capacity requirements have been determined ,

    the organization must decide whether to produce a

    good or provide a service itself. or outsource (buy)from another organization.

    Factors:

    Available Capacity

    If an organization has available the equipment,

    necessary skills, and time, if often makes sense to

    produce an item of perform a service in-house, The

    additional cost would be relatively small comparedwith those required to buy items or subcontract

    services.

    Expertise If a firm lacks the expertise to do the job satisfactory

    buying might be reasonable alternative.

    Quality Considerations

    Firm that specialize can usually offer higher quality

    than an organization can attain itself. Converselyunique quality requirements or the desire to closely

    monitor quality may cause an organization to

    perform a job itself.

    The nature of Demand

    When demand for an items is high and steady, the

    organization is often better off doing the work itself.

  • 8/12/2019 Vi Module Backup

    19/33

    Cost

    Any cost savings achieved from buying of making

    must weighed against the preceding factors. Costsavings might come from the item itself or from

    transportation cost savings. If there are fixed cost

    associated with making an item that cannot be

    reallocated if the service or product outsourced, thathas to recognized in the analysis.

    Risk

    Outsourcing may involved certain risks. One is loss ofcontrol over operations. Another is the need to

    disclosed proprietary information.

    Prepare to deal with capacity chunks.

    o no machine comes in continuous capacities.

    Attempt to smooth out capacity requirements.

    o Unevenness in capacity requirements also can create

    certain problems.

    Identify the optimal operating level.o Production units typically have an ideal or optimal

    level of operation in terms of unit cost of output.

    Economies of Scaleo If the output rate is less than the optimal level,

    increasing the output rate results in decreasing

    average unit costs.

    Diseconomies of scale

    o If the output rate is more than the optimal level,

    increasing the output rate results in increasingaverage unit costs.

    Choose a strategy if expansion is involved.

    o Consider whether incremental expansion or single

    step is more appropriate.

    Cost-Volume Analysis

    o Focuses on relationships between cost, revenue and

    volume of output.FC= Fixed Cost

    VC= Total variable cost

    v= variable cost per unitTC= Total Cost

    TR= Total revenue

    R= Revenue per unitQ= Quantity or Volume of output

    QBEP= Break even quantity P=Profit

  • 8/12/2019 Vi Module Backup

    Fixed Costs (FC)

    tend to remain constant regardless of output

    volume

    Variable Costs (VC)

    vary directly with volume of output

    VC = Quantity(Q) x variable cost per unit (v)

    Total Cost TC = Q x v

    Total Revenue (TR)

    TR = revenue per unit (R) x QProfit (P) = TR TC = Rx Q(FC +vx

    Examples:

    The owner of Old-Fashioned Berry Pies, Simon Chen, is

    contemplating adding a new line of pies, which willrequire leasing new equipment for a monthly payment

    of $6000. Variable costs would be $ 2.00 per pie, and

    pies would retail for $7.00.

    a) How many pies must be sold in order to break-even?b) What would the profit be if 1000 pies are made and

    sold in a month?

    c) How many pies must be sold to realize a profit of

    $4000?d) If 2000 can be sold, and a profit target is $5000,

    what price should be charged per pie?

  • 8/12/2019 Vi Module Backup

    27/33

    Solution:

    FC=$6000 VC=$2 per pie REV=$7 per pie

    a) QBEP= FC/R-V =$6000/$7-$2 =1200 pies/month

    b) For Q=1000; P=Q(R-V)-FC =1000($7-$2)-$6000= $1000

    c) P=$4000; SOLVE for Q using Q=P+FC/R-V

    Q=$4000+$6000/$7-$2 = 2000 pies

    d) Profit=Q(R-V)-FC

    $5000=$2000(R-$2)-$6000

    R=$7.50

    A manager has the option of purchasing one, two, or

    three machines. Fixed costs and potential volumes

    are as follows:

    VC is $10 per unit and R is $40 per unit.

    a) Determine the break-even point for each range.

    b) If projected annual demand is between 580 and

    660 units, how many machines should the manager

    purchase?

    I. Solution:

    a) For one machine:

    QBEP= $9600/$40 per unit-$10 per unit

    = 320 units( not in range, so there is no BEP)

    b) For two machines:

    QBEP= $15000/$40 per unit- $10 per unit

    =500 units

    c) For three machines:

    QBEP= $20000/$40 per unit- $10 per unit

    =666.67 units

    B. Comparing the projected range of demand to thetwo ranges for which a break-even point occurs,

    you can see that the break-even point is 500,

    which is in the range 301-600. this means that

    even if demand is at the low end of the range, it

    would be above the break-even point and thus

    yield a profit. At the top end of projecteddemand, the volume would still be less than the

    break-even point for that range, so there would

    be no profit.

    Assumptions of Cost-Volume Analysis

    One product is involved.

    Everything produced can be sold.

    The variable cost per unit is the same regardless of

    the volume.

    Fixed costs do not change with volume changes, orthey are step changes.

    The revenue per unit is the same regardless of

    volume.

    Revenue per unit exceeds variable cost per unit.
