Your boss at Xiangling Hu Products, Inc., has just provided you with the schedule and lead times for the bracket. The unit is to be prepared in week 10. The lead times for the components a re bracket (I week), base (1 week), spring ( I week), clamp (I week), housing (2 weeks), handle (I week), casting (3 weeks), bearing (I week), and shaft (1 week).a) Prepare the time-phased product structure for the bracket.b) In what week do you need to start the castings?
Product PI is made of one unit of sub assembly A and four
units of sub assembly B. Sub assembly A is made of 4 units
of component X while sub assembly B is made of 2 units of
X. one unit of Y and 3 units of Z. The manufacturing lead
times PI, A, B, X, Y and Z are 1, 1, 1, 4, 6 and 1 (week)
respectively. The lead time for delivery of PI in weeks
is
One unit of A is made of two units of B and one unit of C. B is made of three units of Dand one unit of F. C is composed of three units of B, one unit of D, and four units of E.D is made of one unit of E. Item C has a lead time of one week; Items A, B, E, and F havetwo-week lead times; and Item D has a lead time of three weeks. Lot-for-lot (L4L) lot sizingis used for Items C, E, and F; lots of size 20, 40, and 160 are used for Items A, B, andD, respectively. Items A, B, D, and E have on-hand (beginning) inventories of 5, 10, 100,and 100, respectively; all other items have zero beginning inventories. We are scheduledto receive 10 units of A in Week 3, 20 units of B in Week 7, 40 units of F in Week 5, and60 units of E in Week 2; there are no other scheduled receipts. If 20 units of A are requiredin Week 10, use the low-level-coded bill-of-materials (product structure tree) to i nd thenecessary planned order releases for all components.

- Tots Toys makes a plastic tricycle that is composed of three major components: a handlebar-front wheel-pedal assembly, a seat and frame unit, and rear wheels. Please note that each tricycle requires two rear wheels, the front wheel is included in the front wheel-pedal assembly. The company has orders for 15,000 of these tricycles. Current schedules yield the following information: component plastic time space cost to manufacture cost to purchase front 2 11 2 7 11 seat/frame 3 7 2 6 10 rear 0.5 2.5 0.2 2 5 available 60000 180000 35000 Develop a linear programming model to tell the company how many of each component should be manufactured and how many should be purchased in order to provide 15,000 fully completed tricycles at the minimum cost. Use Excel's Solver to obtain the optimal solution. How many of each component should be manufactured vs. purchased? What is the overall cost? What are the binding constraints?
