Question 1

A process is set up in this order. R, A, B, C, D, S

4 parts are fabricated through this process.

Part # Routing Sequence Quantity per day Weight (lbs) Total Weight Relative importance

1 R,A,C,B,S 1000 1

2 R,D,C,A,B,S 1000 4

3 R,B,A,C,S 1000 3

4 R,C,B,S 1000 2

What is the relative importance of each part. (pg 115)

Create a string diagram for these parts. What is the overall efficiency for these 4 parts? (111 - 113)

Create a multicolumn process chart for these parts. What is the overall efficiency for these 4 parts?(113-115)

Create a From-To chart for these four parts in this process. What is the efficiency? (115-117)

Create an OPERTIONS CHART from this data. Follow the example on page 127.

Two components are fabricated, assembled and packaged

Part 1 One fabrication step

Op 25 = Roll Form 375 pcs/hr

Part 2 - Three Fabrications steps

Op 5 = Strip shear 2225 pcs/hr

Op 10 = Chop 1220 pcs/hr

OP 15 = Form 629 pcs/hr

Assemble Part 1 and Part 2 = Operation 55 at 120 pcs/hr

Packout = 120 pieces per hour
