Proban – probabilistic analysis

Proban is a general purpose probabilistic analysis program that covers calculation needs for example in structural reliability. Proban calculates probability, distribution, first passage probability, crossing rate, and related sensitivity measures. The program is not restricted to a particular problem, but allows users to define functions on input and to attach function libraries to the program in a DLL (Windows). Supporting tools such as flexible modeling of variables and events, deterministic analysis, distribution fit, parameter study, function libraries and distribution library come with the program. A variety of methods like FORM, SORM, adaptive response surface, nested reliability analysis, (adjusted) Monte–Carlo simulation, stratified simulation, directional simulation, design point simulation, axis orthogonal simulation and Latin Hypercube simulation are implemented. Proban has a graphical user interface, maintains models on a database, records commands on a journal file for possible reread and displays, plots and prints model and results.
