Capacity planning, del 1 Flashcards
What is capacity planning?
Capacity planning för att säkerställa att en organisation har tillräckliga resurser för att möta forecasted demand på kort, mellan och lång sikt.
The capability of a manufacturing or service system, for example a facility, process, workstation, to accomplish its purpose or to produce output in a period of time.
Example of capacity planning:
Ability to make enough burgers during a weekday lunch hour to meet customer demand
Ability to handle emergency room patients with a waiting time of 20 minutes or less
Does capacity change over time? Why or Why not?
Capacity is not static, it changes over time as it should to meet changes. Due to 3 factors:
Learning curve
Operational safety
Better capacity planning
Vad innebär learning curve?
Productivity increases over time with learning
Vad är operational safety?
It depends on maintenance planning and replacement-/re-investments
- När maskiner och utrustning slits kan de bli mindre effektiva
- Underhåll och reinvesteringar hjälper att behålla / förbättra kapacitet
Vad är better capacity planning?
Öka servicekapacitet under högtrafikperioder, anställa fler läkare under influenasäsong osv
Areas of capacity planning
- Ammunition
- Electricity capacity
- Vaccine production
- Water governance
- Traffic planning
- Public transportation
- Telecommunications
Why is capacity planning important?
Capacity is costly, but the lack of it can be costly aswell.
Three short-term capacity decisions:
Amount of overtime scheduled for the next week
Number of emergency room nurses on call during a downtown festival weekend
Number of call center workers to staff during the holiday season
Three long-term capacity decisions:
Construction of a new manufacturing plant
Expanding the size and number of beds in a hospital
Number of branch banks to establish in a new market territory
Why can demand be a problem for capacity?
Demand fluctuates. Over time, demand for a product or service will vary systematically. The capacity must be higher than the average demand.
When demand exceeds capacity, we will have waiting costs etc. When capacity exceeds demand, it will be the other way.
Explain economies of scale
Achieved when the average unit cost of a good or service decrease when capacity and or volume of throughput increases
Explain diseconomies of scale
Occur when the average unit cost of the good or service begins to increase as the capacity and/or volume of throughput increases
