Python class for efficient handling of dynamic stock models
Note: This project is no longer maintained. The dynamic stock model class is now part of ODYM, the open dynamic material systems model. The new dsm class of ODYM includes a number of lifetime distributions, different dynamic stock models, is more thoroughly tested, and consistently uses the survival function (sf) to model the decay of age-cohorts. Please check here: https://github.com/IndEcol/ODYM
This project contains a class and a connected unit test for modelling dynamic stocks of materials or products, as used in dynamic material flow analysis and industrial ecology.

Below, a quick installation guide and a link to the tutorial are provided:
a) Installation from the web repository:
This is the easiest way of installing dynamic_stock_model. Github hosts an installation package for dynamic_stock_model, which can be downloaded directly from the command line using pip:
pip install dynamic_stock_model
b) Installation as package:
Pull package via git pull or download as .zip file and unpack. Choose a convenient location (Here: 'C:\MyPythonPackages'). Then open a console, change to the directory ../dynamic_stock_model-master/, and install the package from the command line:
python setup.py install
This makes the package available to Python. At any other place in a system with the same python installation, dynamic_stock_model is now ready to be imported simply by
import dynamic_stock_model
This setup also allows us to run the unit test:
import unittest
import dynamic_stock_model
import dynamic_stock_model.tests
unittest.main(dynamic_stock_model.tests, verbosity=2)
Or, to run a specific test
unittest.main(dynamic_stock_model.tests.test_known_results, verbosity=2)
c) Manual installation, by modifying the python path
Pull package via git pull or download as .zip file and unpack. Choose a convenient location (Here: 'C:\MyPythonPackages\'). Then include in your code the following lines
> import sys
sys.path.append('C:\MyPythonPackages\dynamic_stock_model-master\dynamic_stock_model\')
from dynamic_stock_model import DynamicStockModel
