摘要
本文介绍了一个正交试验软件，它的特，点在于设置了正交模型库，并使用了用户文件系统。软件可根据用户需求安排正交试验方案，并对试验中得到的数据进行计算分析，得出最优的试验方案，帮助决策者进行快速有效的决策。程序采用Ｃ语言编写，可以在ＩＢＭＰＣ系列兼容机的汉字操作系统下运行，具有广泛的应用价值。
篢his paper introduces an orthogonal experimental software，it was set on the li-brary of orthogonal models，and used user′s files system，The software can draw up the ex-perimental combination of factors according to the user′s needs，make calculation and ana-lysis on the data of orthogonal experiments，come to an optimal experimental plan，help tomake a quick and efficient decisfon. The software is programmed in C language，it can berun in Chinese operational system on a computer of IBM PC series compatible，and it haswide applied value.
