Fast Probability Integration (FPI) is a software package designed to aid in probabilistic engineering analysis. It was developed at the (Southwest Research Institute ) for the NASA Lewis Research Center (now known as (NASA Glenn Research Center )). The program is based on the Most Probable Point (MPP) concept. This approach uses a response function that depends on the probabilistic distributions of the input variables. Each particular combination of input variable values has a particular probability of occurrence, which is based on the inputs' distributions. Since each input variable combination results in a particular response value, it follows that the probability of obtaining a given response is equal to the probability of obtaining the corresponding input combination. This information is then applied to determine two quantities of interest: * The probability of meeting or exceeding a requirement (for example, a product that is cheap enough to produce so it can be marketed at a competitive price), and * The most likely combinations of input variables which produce satisfactory response values. ==References== *(Design Considerations For Space Trusses. ) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Fast Probability Integration」の詳細全文を読む スポンサード リンク
