Question

b) Write down the mathematical model to identify logical part families and machine groups (do not solve the mathematical model). Parts Machines A B C D E F G H I - 7

Answer 1

to identify the logical part families and machine code use rank-order method and write down its equivalent numbers and arrange it in the rank orders

plz rate the solution so i can improve further
part families and The Mathematical model to identify logical Machines Groups - so given in the problem- Machines A B Parts l c . E LE 6 Now, applying the Ranke Order clustejing technique to identify logical part families and machine groups - for part machine incidence matrix. so in the Rank order clustering technique, use spreadsheet to convert the binary value of each you into decimal equivalent. o Binary secimal equivalent 8 valued / Rank order I- Poart/Machi Al B -nes c DEL F 956 -dlo 11 82- 66 12 288 . 80 0

Now Reorder the rows in part machine based on increase Rauk onde Past Machine ABC D Е H I Binasyvalues Deumal equaivalent 66/12 82 288 256|168 | 133 80 - 6 7 8 9 L Rank Order 1 1 1 2 3 4 from the above table, the Rauk order is in the form of increasing order. so the part families of I is (A, B, C, D) f II (E. FG, HD and machine group of I is (7,1,412) & for II (318,5,6)
