is in the static physically sense of the fixed volume of container or the space in a building

capacity management

is the maximum level of value added activity over a period of time that the process and can achieve under normal operating conditions

capacity of an operation

is the task of setting the effective capacity of the operation so that it can response to the demands place upon it

capacity management

long term changes and demand and the alternative capacity of strategies for dealing with the changes is usually concerned with introducing or deleting major increments of capacity . we called this task

long time capacity strategy

this usually involves an assessment of the demand forecast over a period of _____ ahead during which time plan of output can be varied for example by changing the number of hours the equipment is used

2 to 18 months ahead

objectives of capacity management

quality speed dependability flexibility costs revenues working capital

three requirements from demand forecast

it is express in terms which are useful for capacity it is as accurate as possible it gives an indication of relative uncertainty

this fluctuation and demand are supply may be reasonable forecastable but some are usually also affected by unexpected variation in the weather and by changing economic condition

seasonality of demand

measure is an increasingly popular method of judging the effectiveness of operations equipment

overall equipment effectiveness

oee it is based on three aspect of performance

time that equipment is available to operate quality of the product or service it creates speed or throughput rate of the equipment

the three pure options available for coping with such variation

ignore the fluctuation and keep activity levels constant + level capacity plan adjust capacity to reflect the fluctuation and demand change +demand plan attempt to change demand to fit capacity availability +demand management

the processing capacity is set at a uniform level to out the planning period regardless of the fluctuation and forecast demand this means that the same number of staff operate the same processes and should therefore be capable of delivering the same aggregate output in each period

level capacity plan

opposite of level capacity plan as one which attempts to match capacity closely to the very levels of forecast demand this is much more difficult to achieve than a level capacity plan as different numbers of staff different working hours and even different amounts of equipment may be necessary in each period for this reason ______plans are unlikely to appeal to operation which manufacture the standard, non-perishable products

chase demand plan

methods of adjusting capacity

over time and idle time varying the size of the workforce using part time staff subcontracting

often the quickest and most convenient method of adjusting capacity is by varying the number of productive hours working by the staff in the operation

overtime and idle time

if capacity is larger covered by work for size or one way to adjust it is to adjust the size of the workplace done by hiring extra stock during periods of high demand and laying them off as demandfalls or high and fire

varying the size of the workforce

in period of high demand and operation by capacity from other organization called ______ this might enable that operation to meet its own demand without the extra expense of investing in capacity which will not be needed after the peak and the demand has passed

subcontracting

the most obvious mechanism are demand management has to change demand through price although this is the probably probably the most widely applied approach in demand management it is more common for services than products

manage demand plan

each of the free pure plants is applied only where its advantage strongly outweight its disadvantages for many organization however this pure approaches do not match their required combination of competitive and operational objectives most operations managers are required simultaneously to reduce cost and inventory to minimize capital investment and yet to provide a responsive and customer oriented approach at all times

mixed plans

in operation which have relatively fixed capital such as airlines and hotels it is important to use the capacity of the operation for generating revenue to its whole potential one approach used by such operation is called blank

yield management

yield is management as especially useful where

capacity is relatively fixed the market can be fairly clearly segmented the service cannot be stored in any way the services are sold in advance the marginal cost of making a sale is relatively low

two methods are particularly useful in helping to assess the sequence consequences of adapting particular capacity plans

cumulative representation of demand and capacity queuing theory

there are two problems with this approach cumulative representation

first may not have the same amount of productive time second capacity level which seems adequate may only be able to supply products after the demand for them has occured

are useful where the operation has the ability to store its finished goods as inventory

cumulative representation of capacity plans
