Assume that there are three Decision-Makers (DMs) with different degrees of expertise in an organization. The What and How criteria are evaluated by these DMs. The DMs have different levels of expertise. The weighted expertise are shown in Figure 1. The DMs follows the linguistic scales as shown in Figure 2.
