SIMBOX

Computer program for the simulation of material-, substance-, energy- and monetary flows in anthropogenic systems

The evaluation, modelling, controlling and assessment of substance flows is crucial for environmental management.

In SIMBOX the system is either manually graphic-interactively or automatically (using a system generator) defined and adapted. Data input is possible in two ways: 1.by assigning data graphically to the objects, 2. by using a data-input interface. The model equations for stationary as well as dynamic systems are defined by the users. For standard models like input-output approaches, built in sets of equations can be used.

SIMBOX offers many calculation modules for different purposes:

• Standard module including the calculation of transfer coefficients from mass flows, the determination of missing flows, the total amount of substance flows etc, all quantities with the corresponding uncertainty.

• Least square fit: best estimates for a given set of flow data.

• Simulations: Solving the model equations including uncertainty, sensitivity analysis and parameter variation respectively.

SIMBOX includes many possibilities to analyse and present the results.

• Visualisation of substance flows and their uncertainties.

• Tables and list of results.

• Data files to export results to other programs.

• Graphical representation of key quantities and key functions.

Originally SIMBOX has been developed for internal use, but since 1995 numerous licences for companies, institutes and universities exist.

Hardware requirements:

SIMBOX has been programmed in Rocky-Mountain-BASIC (HP-BASIC). The program development environment HTBasic is produced by TransEra Corporation 1049 South Orem Blvd. Orem, UT 84058, USA. In Switzerland HTBasic is distributed by Niederer Electronic AG, .Gehrenacker 25, CH-9030 Abtwil.
