User Arrival and Demand (TUDi and TUDp) + +* Tokens representing user demand are generated at the `TUDi` and `TUDp` transitions, which simulate user arrivals at the station and park, respectively. The rate of token generation is governed by an exponential distribution based on `userPatience`. + +#### 2. Users Waiting (PSDi) + +* Arriving users are represented as tokens in the `PSDi` place, where they wait for available cars. If cars are available, tokens (users) will move to the `TUSi` transition where they pick up a car. + +#### 3. Car Pickup and Usage (TUSi and PCU) + +* Tokens (users) that successfully pick up cars move to the `PCU` place, representing cars in use by customers. This transition reduces the number of tokens in the `PSRi` place (cars ready) and increases the tokens in `PCU` (cars in use). + +#### 4. Car Return and Charging (TCCi, TCRi, and PSCii) + +* After usage, cars are returned and go through a charging process. The `TCCi` transition moves tokens from `PCU` to `PSCii` (charging state). Once charging is complete, tokens move through `TCRi` back to `PSRi` (cars ready). + +#### 5. Car Maintenance (TCM, TMPR, and PCM) + +* Occasionally, cars require maintenance. The `TCM` transition moves tokens to `PCM` (cars under maintenance). After maintenance, tokens move back to the `TMPR` transition, eventually returning to the pool of available cars. + +#### 6. User Departure (TUNi and TUNp) + +* If a user waits too long for a car, they leave the system. This is represented by the `TUNi` and `TUNp` transitions, which move tokens from the `PSDi` place without satisfying their demand. \ No newline at end of file -- GitLab
