Tina是一款对时间Petri网支持得比较好的软件，也是我用得较多的一款软件。 它的运行程序是解压后/bin目录下的nd.exe文件(NetDraw)，适用于Windows和Linux操作系统，也就是说他的移植性很好。 Tina的操作也比较特别，很多操作需要借助键盘按键来完成，如：Ctrl + g用来切换软件背景网格线的有无；鼠标中键用来添加库所；Ctrl +鼠标中键用来添加变迁；用鼠标中键在库所与变迁间拖拽可以添加弧。(Tina is a good support for time Petri network software, but also I use more of a software. Its running program is the nd.exe file in the /bin directory after decompression (NetDraw), which is suitable for Windows and Linux operating system, that is to say, his transplantation is very good. The Tina operation is relatively special, many need to use the keyboard to complete the operation, such as: Ctrl + G software used to switch the background grid line has no; the middle mouse button to add library; Ctrl + mouse button to add change; with the middle mouse button in the places and transitions between the drag to add arc.)
