A very small company is interested in the design and development of two different products, ABC and PQR. Product "ABC" is not a too difficult product, whereas product "PQR" is an extremely difficult product to design. However, both of them use the same parts in different quantities except that one unique part is required for product "PQR". Determine the time it takes to design each of the two products and the total time for both products. 20 Points The details of the models are given in table below. Product ABC Sub-Assembly - 1 2 of part X and 1 of part Y Sub-Assembly -2 3 of parts X, 2 parts of Z Product PQR Sub-Assembly -1 (same as Product ABC ) Sub-Assembly -2 (same as Product ABC ) Sub-Assembly-3 ( 10 parts W, 30 parts Y, and 20 parts Z) Sub-Assembly- 4 40 of part Y and 25 of part Z Note: Time required to design a part or sub-assembly will have to be estimated only once.
