SysMPy 0.0.9

A library for System Modeling Runtime Environment (SMRE)

SysMPy

About

SysMPy is an open-source library for System Modeling Runtime Environment (SMRE), an integrated software environment which offers several built-in libraries to support systems analysis and design, based on a convenient systems modeling script language, which forms a fundamental building block of SMRE.

Install SysMPy via PIP

Example 1: Three action nodes

pip install sysmpy

Systems Modeling Script (SMS) Example

This tutorial walks you through how to run a simple SysMPy project. It will show you how to write a simple system modeling script and execute it.

Example 1: Simple Three Action Model

This tutorial uses a simple project named a simple three action model. If you are unfamiliar with Python, take a time to study Python (https://www.python.org/).

SMS has a simple form as shown the following code. To define a process, a class Process(.) can be used. The return object from it provides a built-in function Action(.). By including the name of an Action, the Action node is defined along the process.

from sysmpy import *
import asyncio

p = Process("Process")
act1 = p.Action("Action1")
act2 = p.Action("Action2")
act3 = p.Action("Action3")

The following figure shows an illustrative graph from the above code.

                +---------------+
                |               |
                |     start     |
                |               |
                +---------------+
                        | Process
                        |
                +---------------+
                |               |
                |     Action1   |
                |               |        
                +---------------+        
                        |
                        |
                +---------------+
                |               |
                |     Action2   |
                |               |        
                +---------------+        
                        |
                        | 
                +---------------+
                |               |
                |      End      |
                |               |
                +---------------+

After writing the action model, we can run a simulation. To execute the simulation, asyncio.run(.) is used with the built-in function sim() of the process p.

asyncio.run(p.sim())

Prerequisites for Matlab

The following package would be needed to run some examples for Matlab.
