1. An airport management uses a single security line comprising an X-ray scanner for carry on items, and a screening station for passengers. Upon arrival, the customers first prepare themselves for the inspection: They remove belts, coats and shoes, empty their pockets, and separate their electronic devices from other personal items. They then put all bags and electronic devices in trays on the scanner to be monitored, meanwhile they proceed personally to the screening station in parallel. Once the screening (both the passenger and their luggage) is completed, passengers retrieve their belongings, put on their shoes, belts, and coats, and exit the facility. On average, it takes passengers 60 seconds to prepare for the line and to place all carry-on items in the trays for the X-ray scanner. The X-ray scanner takes 40 seconds per tray, and the average passenger utilizes 2 trays. The personal screening station requires 60 seconds per person. Finally, retrieving of belongings and getting reorganized takes 60 seconds. All the times mentioned represent activity time at the various activities and do not include the effects of waiting. 1 draw a process map for the security check process 2. what is the duration of critical path 3. Based on a random sampling and recording the time required for each passenger to clear the security Check, the average of the individual times was 320 seconds. Considering that the theoretical flow time is equal to what you calculated in section 1-2, what is the process flow time efficiency? 4. How much impact on the overall process flow time it will have to expedite the personal screening activity and make it 20 seconds instead of 30?
