TPS Manufacturing Corporation is researching into available vendors (suppliers) for sourcing of raw materials, parts, and components. It identified six critical factors and finalized four vendors, and it needs to select only one supplier as a single source. TPS is combining both quantitative and qualitative measurements into one cohesive approach to rank and evaluate these suppliers. Each critical factor is given a weight of 1-10 and each supplier is rated from a scale of 1-10 based on his ability to meet the requirements of each critical factor. The weights and the scale are not related to each other.
