Abstract: The rising volume of information conveyed and the speed of work are becoming increasingly necessary applications and devices to meet these requirements. Thus, in the actual society of knowledge, the impact of the new informational technologies was extended even in an important domain of human activity: the adoption of decisions. Consequently, the necessity of objecting at the selection process of the most favorable decision lead to the extension of the usage of information technology also in the conceptual phase. The decision tools suite (DTS) and the expert systems have the answer for the computer science workers at the needs of the deciders, used especially in the case of the decisions adopted in conditions of risk or uncertainty. The PALISADE package of programmers is a support system of decisions, which overlaps the processor tables, increasing the possibility of usage, especially for simulation problems, calculating the risk, building decision trees etc.
Keywords: computerization, simulation, palisade, risk, decision, analysis
