In this section you get support for everything that is connected to Material Flow Analyses and STAN.

Here you find the online help of STAN 2.5.


A picture says more than a thousand words. And a video is even better. Here you can find help videos that show you how to work with STAN.

In October 2021, STAN was celebrating its 15th birthday! As a present to our users, we have created a brand new series of video tutorials covering every aspect of STAN.

Video 1: Lecture unit "STAN and Uncertainties in MFA" from the course "226.054 Resource Management", recorded on November 08, 2018, at TU Wien (62 min)

This video covers the basics of Material Flow Analysis (MFA) and shows how to handle data uncertainties by using statistical tools like data reconciliation & uncertainty propagation: the goal of MFA (01:55), defining system boundaries (02:26), goods vs substances (04:30), using multiple periods (08:08), equations used in MFA (09:42), a mathematical model of a small example (15:05) + exercise 1 (18:19), introduction to uncertainties (21:17), using significant digits (31:58) + exercise 2 (34:04), error propagation (35:34) + exercise 3 (39:35), data reconciliation (39:46), summary (56:31), books & website (57:37), why is an MFA software needed (58:22), a brief explanation of what STAN is doing (1:00:20).

Video 2: Short introduction into the basics of STAN 2.5, recorded July 26, 2012 (17 min).

This video covers how to adjust the user interface (00:05), reset the user interface to default (01:09), create a simple graphical model (01:26), change the properties of objects (06:13), change process properties (06:51), rename objects (08:50), enter data (09:59), insert a legend (11:50), start a calculation (12:13), insert a transfer coefficient (13:05) and create a nice looking flow diagram (14:35).

Video 3: STAN webinar (hosted by ISIE), recorded on April 20, 2018 (55 min)

This video covers how to download and install STAN (03:27), create a simple graphical model (04:27), change the language of STAN (06:02), enter data and perform calculations (11:07), consider data uncertainties (15:35), use statistical tools like uncertainty propagation (18:00) and data reconciliation (19:55), detect errors like contradictions (20:35) and gross errors (24:54), use multiple layers and periods (27:05) and import data (32:16).

Additionally, at the end of the video, there is a short Q&A session (40:50) covering the topics standard deviation vs standard error (41:17), separation of one flow in different others (42:48 and 50:43), calculation of transfer coefficients (44:55), energy flows in STAN (46:19), plotting time series (48:19), maximum model size and commercial algorithm IAL-IMPL2013 (49:15) and dynamic modeling with additional relations (52:22).

Here you can find a short introduction into the basics of Material Flow Analysis (MFA).
