SMAH: a new software package for evaluating major accident hazard

The mathematical models are very useful tools to predict the impacts of chemical process accidents. However, application of the models requires people competent in mathematic and computer programming. This paper presents a developed tool called ´Simulation of Major Accident Hazards´ (SMAH). It is a software package which would be more users friendly and effective for evaluating the consequences of major accidents. It was developed using visual basic language (VB) whose its state of art consists of a graphic user interface (GUI) as front end and mathematical models as a back end (source code). Furthermore, results of calculations using the codes can be presented in tabulated and graphical forms, can be saved and transferred (exported) to the GIS software for risk presentation. This paper aims to present the framework of the simulator.
