Assign weights to classes user defined M 4 P 3 S 5 T 5 X 1 Step 4. Filter Table to obtain only columns of required objectives. This step results in Table . Step 5. Remove from the filtered table all methods that have one or more column blank . the method does not meet that objective . See table . Step 6. Convert the methods grades from alphabetical to numerical using conversion factors as follows a 6 b 4 c 3 d 1 Table Method number Class Objective 2 3 6 7 13 9 M c b b b c 14 X b c b b c 20 S c d d b b 37 X c c b b b 38 X d c c b c 39 S b b b b b 43 M c b b b c 50 P b c c c b 68 T b c b b c 94 M c b b b c 98 M d b b c c Decision-making - method selection 51 Table Method number Class 2 3 6 7 13 9 M 3 4 4 4 3 14 X 4 3 4 4 3 20 S 3 1 1 4 4 37 X 3 3 4 4 4 38 X 1 3 3 4 3 39 S 4 4 4 4 4 43 M 3 4 4 4 3 50 P 4 3 3 3 4 68 T 4 3 4 4 3 94 M 3 4 4 4 3 98 M 1 4 4 3 3 The conversion is shown in Table . Step 7. Multiply the weight column grades by the method grade row and replace the result in the grade location as shown in Table . Step 8. For each method row sum the replaced grade values and list them in an additional column method weight for each row as shown in Table . Step 9. Multiply the values in the additional column by the class weights and place the results in the final column Total value of Table . The highest total value is 760 and it recommended that method 39 ERP be used. Example of selection of methods to meet several functions Step 1. The company requires a manufacturing method
