Final answer:
An assembly-time chart indicates gross requirements, net requirements, and current available inventory, which are important for managing inventory in manufacturing, particularly under a just-in-time delivery system. The correct answer is 4) All of the above.
Step-by-step explanation:
An assembly-time chart is a tool used in the manufacturing process to indicate a variety of key inventory metrics in relation to the assembly of a product. It includes:
- Gross requirements: The total demand for components before any inventory is considered.
- Net requirements: The actual demand that must be met after considering the current available inventory.
- Current available inventory: The number of parts on hand, ready to use in production.
The chart is critical for managing the manufacturing process efficiently, particularly in systems like just-in-time delivery, where having too much or too little inventory can impact production flow, costs, and quality control.
