SysMPy 0.0.3

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.

Systems Modeling Script (SMS)

Example 1: Three action nodes

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 entity import *

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 building the 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())
