, the SIMPY model may or may not be suitable for conceptual scenarios, and it is easy to imagine that resources are inherently limiting their utilization (for example, if the server computer does not have a satisfactory response within the required timeframe, it interrupts the connection). But as a programming issue, whether a process or resource is an "active" side is not particularly important (just make sure you understand your intentions). The last SimPy class is the monitoring program. In f
