Value Path Approach for the Supplier Selection Case Study

1 Value Path Approach for the Supplier Selection Case Study 

The supplier selection case study was solved using four different GP approaches as previously illustrated. A summary of the results is provided in Table 6.38. 

To present these results to the DM, value path approach is used as follows  

Find the best (minimum) value obtained for each criterion. For the price criterion, preemptive GP has the best value of 203,302 for the lead-time criterion Preemptive GP is best with a value of 4648 and for the quality objective the best value of 27.53 is obtained through Fuzzy GP. 

For each solution, divide their objective values by the best value for that objective. For example, for fhe preemptive GP solution, the value
