ExpertFit allows you to determine automatically and accurately what probability distribution best represents a data set.  In many cases a complete analysis can be done in a few minutes.  A secondary goal is to provide simulation analysts with assistance in modeling a source of randomness (e.g., a service time) in the absence of data.

ExpertFit is extensively used by analysts performing discrete-event simulation studies of real-world systems in such application areas as manufacturing, military planning, transportation, healthcare, contact centers, and communications networks.  For these users, ExpertFit will take the selected distribution and put it into the proper format for direct input to your simulation software.  It is also employed in such diverse disciplines as actuarial science, agriculture, chemistry, economics, environmental analysis, finance, forestry, hydrology, medicine, meteorology, mining, Monte Carlo simulation, physics, psychology, reliability engineering, and risk analysis.  

expertfit是flexsim内嵌的随机变量分析工具,它是由Averill Law 和 Associates开发的用来确定输入数据的最佳匹配的统计概率分布的程序我们把实际测得的数据加载到EXPERTFIT随机数据分析软件后,它会迅速而准确的统计出其平均值、方差等各种随机变量分布特征参数,并确定出与样本数据最符合的概率分布类型和相关参数。这对我们用FLEXSIM仿真软件对实际系统进行仿真分析带来了很多方便。
