Shop Floor Control - General Considerations
5 important questions on Shop Floor Control - General Considerations
What is the purpose of gross capacity control?
To stabilize the environment in which the SFC module must operate, to ensure that lines are close to optimally loaded and drastic sings in line speed are avoided.
If a plant already runs three 8-hour shifts, 7 days a week, does this plant have any (gross) capacity control options left?
This is dependent onf the characteristics of the current situation. If the plant is still lacking some capacity, then it could still decide to outsource some part of production (if it isn't an extremely specialized production).
It could also (probably) up staffing or machining levels.
(These are options 5 and 4 in 14.2.1.)
Of course it can also use all, or most of the options in 14.4.2 to go back from a situation of high demand to low demand.
It is important to realize what the current situation is before answering this question.
What is a ''floating bottleneck''?
A floating bottleneck refers to a bottleneck that isn't distinct. This means that, in a multi-product setting, the bottleneck station or machine depends on the product mix and 'switches' accordingly.
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
Why are stable bottlenecks easier to manage?
Because they are simpler to model and control.
What is meant by 'the design of a bottleneck'?
Pro-actively influencing the production process in order to make only (a) certain station(s)/machine(s) act as the bottleneck.
