Using the information given below, draw the Product Structure Diagram, perform MRP calculations and answer the questions as listed.

In order to product one unit of the end item ELOG65, three required various subassemblies. One ELOG65 consists one item B, 2 item C and D assembled together in final assembly. Before the final assembled, three item E and forty-five item F are produced to one item B, while two item G and nineteen item H are produced to one item D. However, producing product ELOG65 require one day, and also getting item B, E, and G require two days, and item C, F and H require one day, while item D require 3 days.

The product ELOG65 assembly problem is a three-level MRP system. Level 0 corresponds to the final product, which is the completed product ELOG65. Level 1 relative to the product ELOG65, corresponds the item B, C and D assemblies. Level 2 corresponds to the item E, F, G and H assemblies. The information given present a Bill of Materials (BOM), which will be used for computational.

Therefore, you were hired as the manufacturing manager, your job is to manage the overall production process to ensure that your company have enough raw materials to respond with the production process and customer demands.
