Question

.29 Four workstations (1.2,3, and 4) are used to produce similar parts. The stati arranged into a work cell with an in-line layout. The daily flow of parts between stations is as follows: 15 parts from stations 2 to 4,60 parts from stations 3 to 2,35 parts from stations 2 to 1, 20 parts from stations 4 to 3, and 30 parts from stations 4 to 2. (a) Use the Hollier algorithm to determine the most logical sequence of stations in the work system. (b) Draw the network diagram for the system. (c) Compute the percentages of in-sequence, bypassing, and backflow moves for the sequençe work

Answer 1

Solution Hollier algorithm: From()Tol1 23sums From Ratio 0.00 35 50 35 0 0 15 50 0 60 0 060 0 30 20 050 To sums 35 90 20 15 160 0.55 90 60 = 3.00 20 50 - 3.33 15 From the above table, the ratio is 3.33>3>0.55 >04321 Therefore, the most logical sequence of stations in the work system is 4-32-1 Netw ork diagram for thesystem:
