3. Four workstations (1, 2, 3, and 4) used to produce a family of similar parts A, B and C.The daily flow of parts between workstations is as follows: Part A: 40 parts from stations 1-2-3-4. Part B: 30 parts from stations 1-4-2-3-4, Part C: 60 parts from stations 3 - 1 - 2 - 4 (a) (3 points) Draw the network diagram for this work system. It should show the combination of all the parts and the total flow of parts between stations (b) (5 points) Prepare the From-To table for this work system. Label columns and Rowscorrectly. (c) (2 points) Compute the percentage of in-sequence moves, by-passing moves, and backflow moves for the sequence.
