Assign weights to classes user defined M 4 P 3 S 5 T 5 X 1 Step 4. Filter Table 4.1 to obtain only columns of required objectives. This step results in Table 4.3.1. Step 5. Remove from the filtered table all methods that have one or more column blank i.e. the method does not meet that objective . See table 4.3.2. Step 6. Convert the methods grades from alphabetical to numerical using conversion factors as follows a 6 b 4 c 3 d 1 Table 4.3.2 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 4.3.3 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 4.3.3. Step 7. Multiply the weight column grades by the method grade row and replace the result in the grade location as shown in Table 4.3.4. 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 4.3.5. 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 4.3.5. The highest total value is 760 and it recommended that method 39 ERP be used. 4.3.2 Example of selection of methods to meet several functions Step 1. The company requires a manufacturing method
