Concept explainers
a)
To construct: A product structure.
Introduction:
Product structure:
The product structure is a visual representation of the components needed for a product assembly and the sequence at which they must be developed. It will clearly depict the parent and children components at each level.
b)
To construct: A time-phased product structure.
Introduction:
Time-phased product structure:
The time-phased product structure will represent the product visually with the details, when each component must begin the production. It should be done to ensure that all the components are on time.
c)
To develop: A net requirements plan.
Introduction:
Net requirements plan:
The net requirements plan is the plan, which is established on the gross requirements plan formed by deducting the stock on and the

The base is assembled from 1 clamp and 2 housings. Each clamp has 1 handle and 1 casting. Each housing has 2 bearings and 1 shaft. There is no inventory on hand. A. Design a product structure noting the quantities for each item and show the low-level coding. B. Determine the gross quantities needed of each item if you are to assemble 50 brackets. C. Compute the net quantities if there are 25 of the base and 100 of the clamp in stock.arrow_forward

- Figure shows the BOMs for two products, A and B. Table 1 shows the MPS quantity start date for each one. Table 2 contains data from inventory records for items C, D, and E. There are no safety stock requirements for any of the items.a. Determine the material requirements plan for items C, D, and E for the next 8 weeks.b. What specific managerial actions are required in week 1?c. Suppose that a very important customer places an emergency order for a quantity of product A. To satisfy this order, a new MPS of 200 units of product A is now required in week 5.
