CLSC OnlineShop Model Numeric Solver

This project is part of my master's thesis. The goal is to create a full factorial analysis of some (new) mathematical closed-loop supply chain models.

Installation

You can download this project by clicking Clone or download and Download as ZIP or directly cloning it via git.

Download via git (recommended)

First, you have to install git:

$ sudo apt-get install git

To download the repository, clone it to your pc using:

$ git clone https://github.com/yanickdi/clsc_numeric.git

A new folder called clsc_numeric was created. Make sure to update your local copy by and by, using the git pull command:

$ cd clsc_numeric
$ git pull

Download via direct zip download

Just download and unpack the zip folder, you can use your terminal:

# change to your Downloads folder:
$ cd ~/Downloads/
# download the zip file using wget
$ wget https://github.com/yanickdi/clsc_numeric/archive/master.zip
# and unzip the downloaded package:
$ unzip clsc_numeric-master.zip
$ mv clsc_numeric-master clsc_numeric

Software requirements

This solver requires Python3 and SciPy to run. To create html output you will also need Jinja2 Template Engine. For plotting, you have to have Matplotlib installed.

On Unix environments this may will work:

$ sudo apt-get install python3 python3-scipy python3-matplotlib python3-pip
$ sudo pip3 install jinja2

Usage

documentation in progress. If you want to check whether the solver is working - just open a terminal, change to your downloaded folder and start generator.py like:

# change to your project folder:
$ cd clsc_numeric
#
# start all test cases:
$ python3 tests.py
# start test cases for model one:
$ python3 tests.py TestModelOneNumericalSolver
#
#

# CALC SOME NUMERIC RESULTS

$ python3 generator.py -model 1 -output stdout
# or create a .csv file of some numeric results:
$ python3 generator.py -model 1 -output numeric_results.csv

# csv results for model 2:
$ python3 generator.py -model 2 -output model_2.csv --german-comma

# html results for model 1:
$ python3 generator.py -model 1 -output model_2.html

# want to see only valid solutions:
$ python3 generator.py -model 1 -output model_2.html --only-valid-solutions

# PLOTTING

$ python3 plotter.py -plot profit-difference-man
or
$ python3 plotter.py -plot profit-difference-ret
or
$ python3 plotter.py -plot rho-difference
or
$ python3 plotter.py -plot cases-model-one
or
$ python3 plotter.py -plot cases-model-two
or
$ python3 plotter.py -plot compare-cases
# if you are in a hurry
$ python3 plotter.py -plot any-plot-from-above --low-qual
# plot profit-difference and rho-difference not only be calculated with relative increase but with absolute:
$ python3 plotter.py -plot profit-difference --absolute
# to get a gray-scale colour map:
$ python3 plotter.py -plot cases-model-two --gray
