!!What decisions define the capacity strategy of a business?
''Configuring'' the capacity and ''Changing'' the capacity
''Configuring'' - Overall level of capacity - based upon forecasting or [[Category Killers]], [[Economies of Scale]]. The ''location'' of capacity - the number of sites, image , customer service levels, capital requirements, govt grants, education and skills, need to be close to or far away from customer, energy costs, other similar compnaies in the area - silicon valley.

''Changing'' the capcity - is how the capcity should be changed - large or small steps, how fast or slow, lagging or leading demand

''Utilization = Actual capacity/total capacity
''Efficiency = Actual o/p / effective capacity

!! Capacity at three levels
...................................................................................................................................Starting pt for dec
Strategic = years/mths........................Buildings...............all parts of business...................mkts to serve.................how much cap to we need
M-term = mths/wks.............................Employees............site...........................................cap constraints..............should we change staff nos
s-term = wks/hrs.................................Employee..............dept.........................................current cap....................resources to allocate

''Level of Capacity'' is determined by EoS, K, Flexibility and Forecast, changes on future demand, uncertainty and consequnces of over / under supply

!!How do capacity decisions differ for different time scales
the need for resources, where demand fluctuates monthly weekly, scale of investment - buildings

!!How much capacity should a company have
abaility to increase or reduce capacity quickly, ration of fixed to VC

!!How does the timing of capacity change influence performance of the operation
Capacity can lead or lag demand. or be a combination. Lead demand on a new product, using inventory smooting when plateauing and lag demand when mature. Issues - Lead demand - future demand may not be forthcoming - higher cost producer. Smoothing - Higher [[Working Capital]], doesnt work in a service industry . Lag demand - potential loss of sales -

!!How does operation choose between large and small increments of capacity
**Can be significant lags between deamdnand supply when large increments are planned.
**Uisng small increments is less costly but leads to more disruption
**Building new capacity in an laready well served area can reduce prices. Over capacity happens becuase the compnay adding the new capcity can do it for cheaper and wont be affected. Also deciosn were made when demad was high - microprocessors
**Balancing capacity change - deciosn may be right for the manufacturing plant - but how will be affect the capcity of downstream or up stram activities - can suppliers cope with new demand, can distributors store products - what additonal costs are involved
** Building facility for large capcity but only bringing it on stream when needed

Chnaging locations - different types of factories - outsourcing, server, output, source, off-shore -
''what are the characteristics of the factory?
** - low skills v high skills,
** proximity to market,
** access to low costs - labor / materials
** Community factors - decision is multivariate

''What are the market factors
** Image of location - Hotel - prestige area, hosting center - cheap area
** Service level - where to site hospital

''[[Game theory]]

!!Managing capacity changes
**Lagging and leading and smoothing with inventory
**Issues of over capacity in the industry and how that is managed
** [[Disruptive Technologies]] that redine the mkt
**Balancing capacity change with upstream and downstream ops
**Changing loacation
***configuration and coordination - unions-cost-political factors- legal- mkt requirements and operationsal resources
