A manufacturing bottleneck is a constraint or choke point that limits production output. Many manufacturing operations suffer from bottlenecks caused by one or more machines and the bottleneck may change depending upon the actual product being manufactured.
In the case of hiking, a bottleneck means the slowest member in walking. An interval between the bottleneck member and the one before spreads, and narrows with the one after. An important thing about bottlenecks is that bottlenecks determine the throughput of a supply chain.If a bottleneck person in hiking can walk faster, the speed of the whole group will increase.Similarly, if the capacity of a bottleneck in a supply chain improves, the throughput will increase. From the definition of bottlenecks, the operating rate of non-bottlenecks is below 100%. bottleneck (or constraint) in a supply chain means the resource that requires the longest time in operations of the supply chain for certain demand. Usually, phenomena such as increase of inventory before a bottleneck and insufficiency of parts after a bottleneck are often seen.
