# Discrete Event Simulation

Library to run a simple discrete event simulation. Runs on simpy.

## Installation

1. Clone the repository

2. Run the following commands:

  `pip install wheel`

  `pip install .`

3. Now the package `desim` is installed. 

## Running a simulation

To run a simulation the suggestion is to use the interface provided in `desim/interface.py`

There the different types of simulations are provided. 

Example code of running a monte carlo simulation:

```python

from desim.interface import Des

from desim.data import NonTechCost, TimeFormat

from desim.simulation import Process

dsm = dict({

    'Design Process': [0, 1, 0],

    'Testing Process': [0, 0, 1],

    'Manufacturing Process': [0, 0, 0.2]

})

processes = [

  Process(1, 10000, 100000, 0, 'Desing Process', NonTechCost.CONTINOUSLY, TimeFormat.MONTH),

  Process(3, 5000, 30000, 0, 'Testing Process', NonTechCost.CONTINOUSLY, TimeFormat.YEAR),

  Process(4, 300, 200, 100, 'Manufacturing Process', NonTechCost.CONTINOUSLY, TimeFormat.HOUR),

]

non_tech_processes = [

  NonTechnicalProcess("Quality Mangement Process", 10000, 0)

]

flow_time = 3 

flow_rate = 260

flow_start_process = "Testing Process"

non_tech_cost = NonTechCost.CONTINOUSLY

time_unit = TimeFormat.YEAR

until = 30

discount_rate = 0.08

runs = 100

sim = Des()

results = sim.run_monte_carlo_simulation(flow_time, flow_rate, flow_start_process, processes, 

          non_tech_processes, non_tech_cost, dsm, time_unit, discount_rate, until, runs)

```
