Assignment 3
1. Customers arrive at a vehicle service centre for check up; customers wait their turn in the waiting area. Customers are served on the first come first served basis. When his turn comes, the receptionist tests the car for preexisting conditions. The customer waits in the waiting area while the vehicle waits its turn. The vehicle is checked for suspension errors at work station 1, then the motor is checked at work station 2, and finally the brake system is checked in work station 3. Vehicles are served on FIFO basis, and the transportation time between work stations is negligible. The vehicle is returned to the waiting area until the customer pays the bill and they both leave.
Draw an outline process map to model the process.
Define entities, locations, resources, networks, and processes used to model the process.
