pyspa - An object-oriented python module for structural path analysis

Abstract

pyspa is an object-oriented python package which enables you to conduct a parametric structural path analysis on square A matrices (process or input-output) for any number of environmental, social or economic satellites and for any number of stages upstream in your supply chain (as long you have enough RAM). The package produces a SupplyChain object which includes Pathway and Node objects. Results can be exported to the csv format with a single line of code. The concept behind pyspa was driven by the lack of open source code to conduct structural path analysis in a robust and object-oriented manner.
