# SimQ

Queueing network tool based on SimPy.

# Installation

```bash

pip install SimQ

```

# Example

The following is a simple example of using SimQ to simulate a single-node queueing system.

```python

import simpy

from simdist import dists

from simq.core import Network, Node

SIMULATION_TIME: float = 30.0

def leave(customer_id: int, current_queue: Node, queue_system: Network) -> None:

    queue_system.log(

        {

            "customer": customer_id,

            "action": "routing",

            "node": current_queue.name,

            "destination": "exit",

        }

    )

env = simpy.Environment()

queue = Node(

    env,

    name="Queue 2",

    num_servers=1,

    service_time_dist=dists.Gamma(5, 5),

    inter_arrival_dist=dists.Gamma(1, 2),

    routing_strategy=leave,

)

system = Network(env, [queue])

system.start_customer_generation()

_ = env.run(until=SIMULATION_TIME)

for entry in system.event_log:

    print(entry)

```
