Question

With respect to physical constraints in production, please compare Bottleneck Work Activity Vs. Non Bottleneck Work Activity.

Answer 1

Ans.Resources with no excess capacity are referred to as bottleneck or constraint resources, while those with excess capacity are referred to as non-bottleneck or non-constraint resources.

• Bottleneck Resource: Any resource whose capacity is equal to or less than the market demand placed on it.
• Non-Bottleneck Resource: Any resource whose capacity is greater than the market demand placed on it.

To understand the difference between these two types of resources, then it’s important to recognize how time on each one should be spent. The available time can be used in different ways based upon the following definitions:

·      Processing Time: The time required to process materials at a specific operation, not including setup time.

·      Setup Time: The time required for a specific machine, resource, work center or line to complete the conversion from one product to another product including the testing and acceptance of the new product.

·      Idle Time: Time not used for processing material or setting up a specific machine, resource, work center or line.

·      Wasted Time: Time spent processing materials that cannot be realized as throughput. This time includes rework or scrap materials, work-in-process materials that are not scheduled or needed or finished goods above and beyond immediate demand.
