Discrete Event Simulation: Customs Checkpoint Simulation System 【Problem Description] Consider a customs checkpoint responsible for checking transit vehicles and develop a concrete simulation system. For this system, the following basic considerations are assumed: (1) The duty of the customs is to check the passing vehicles, here only one direction of traffic inspection is simulated. (2) Assuming that vehicles arrive at a certain rate, there is a certain randomness, and a vehicle arrives every a to b minutes. (3) The customs has k inspection channels, and it takes c to d minutes to inspect a vehicle. (4) Arriving vehicles wait in line on a dedicated line. Once an inspection channel is free, the first vehicle in the queue will enter the channel for inspection. If a vehicle arrives with an empty lane and there is no waiting vehicle, it immediately enters the lane and starts checking. (5) The desired data include the average waiting time of vehicles and the average time passing through checkpoints. 【Basic Requirements】 The system needs to simulate the inspection process at a customs checkpoint and output a series of events, as well as the average queuing time and average transit time for vehicles. [Extended Requirements Please modify the customs checkpoint simulation system to use a management strategy of one waiting queue per inspection channel. Do some simulations of this new strategy and compare the simulation results with the strategy of sharing the waiting queue.
