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

- A firm that produces electric golf carts has just received an order for 200 carts, which must be ready for delivery at the start of week 8. Information concerning the product structure, lead times, and quantities on hand is shown in the following table. Use this information to do each of the following: a. Develop a material requirements plan that will provide 200 golf carts by week 8, assuming lot-for-lot ordering. (Excel)arrow_forwardProduct A is assembled from two units of S1 and threeunits of S2. S1 is made of one unit of C1, four units of C2,and one unit of C3. S2 is made of three units of C2 and twounits of C3.a. Draw a product structure diagram for product A.b. How many C3’s are needed to fill an order for 100 A’s?c. Assume no inventory on hand, products take one day to assemble, subassemblies take two days and compo-nents take three days. When should an order be re-leased for C3 if the 100 A’s are needed by day 7?arrow_forwardConsider the following product structure (bill of material). One hundred and fifty (150) units of Product A are needed in week 10. Assuming no on-hand inventory of A exists, explode the bill of material, and use the following information to construct a net requirements plan for all the items. You must use the template provided by the instructor and provide all the information needed on the template. There are no scheduled receipts for all the items.

- As the production planner for Xiangling HuProducts, Inc., you have been given a bill of material fora bracket that is made up of a base, two springs, and fourclamps. The base is assembled from one clamp and twohousings. Each clamp has one handle and one casting. Eachhousing has two bearings and one shaft. There is no inventoryon hand. a) Design a product structure noting the quantities for eachitem and show the low-level coding.b) Determine the gross quantities needed of each item if youare to assemble 50 brackets.c) Compute the net quantities needed if there are 25 of thebase and 100 of the clamp in stock.arrow_forwardA standing desk consists of a desk top, four legs, and two adjustment motors. Each leg fastens to the desk top with one fastener set. Each adjustment motor requires two fastener sets for attachment to the legs. Currently there is one order outstanding, to make 180 standing desks. There are 500 legs and 20 desk tops in inventory. There are no other large items in inventory, and no scheduled receipts.(a) Draw the product structure tree.(b) Calculate the net requirements to fulfill the outstanding order.arrow_forwardProduct A is assembled from two units of S1 and threeunits of S2. S1 is made of one unit of C1, four units of C2,and one unit of C3. S2 is made of three units of C2 and twounits of C3.a. Draw a product structure diagram for product A.b. How many C3’s are needed to fill an order for 100 A’s?c. Assume no inventory on hand, products take one day toassemble, subassemblies take two days and components take three days. When should an order be released for C3 if the 100 A’s are needed by day 7?arrow_forward
- A table is assembled using three components, as shown in the accompanying product structure tree.The company that makes the table wants to ship 100 units at the beginning of day 4, 150 units atthe beginning of day 5, and 200 units at the beginning of day 7. Receipts of 100 wood sections arescheduled at the beginning of day 2. There are 120 legs on hand. There are 60 braces on hand. Leadtimes (in days) for all items are shown in the following table. Prepare a material requirements planusing lot-for-lot ordering.arrow_forwardDraw a product structure and a indexed bill of materials for the following product: the final product 'A' consists of a subassembly 'B' and two subassemblies 'C'. Subassembly 'B' consists of one component 'D' and two components 'E'. Subassembly 'C' consists of one component 'E', one 'F', and two 'G'.arrow_forwardProduct A consists of subassemblies B and C. Subassembly B requires two parts of D and one part of E. Subassembly C requires one part of D and one part of F.a. Draw a product structure tree (BOM) for this product.b.
