3. 14.11 An airport baggage handling department has evaluated two proposals for baggage delivery conveyor systems. A present worth analysis at i = 15% per year of estimated revenues and costs resulted in PWA = $460,000 and PWB = $395,000. In addition to this economic measure, three more attributes were independently assigned a relative importance score from 0 to 100 by the department manager and a senior team supervisor. Table Summary: Table divided into 2 main columns summarizes the importance scores given to 4 attributes important in baggage handling by the Manager and Supervisor. The column headers are: Column 1: Attribute, I; Column 2: Importance Scores. Column 2 is further divided into 2 columns with the headings: Manager and Supervisor.
