CUBE Voyager requires a Windows XP, Windows Vista, Windows 7 or Windows 8 environment in which to function. The system utilizes RAM as needed; most applications will not require any special RAM considerations. The exact amount of RAM required can not be determined until an application actually runs and the combination of user options is diagnosed. It is fairly safe to state that if a computer can run Windows, it has enough RAM to run CUBE Voyager.

About 10GB of disk space is required to install CUBE Base and CUBE Voyager. 100GB or more may be required for model outputs. A typical application will require zonal data files, networks, and matrices. Zonal data files are not very large, and network sizes will depend upon the number of alternatives and variables that the user wishes to employ. The largest networks will be only a few MB. The largest storage requirements will be associated with matrices. A matrix will contain zones × zones cells of information. Each cell value can be from 0 to 9 bytes in size, but CUBE Voyager uses a proprietary data compression technique that helps to reduce the sizes. The user can control the matrix sizing.

CUBE Voyager is designed to run in a multitasking environment. In such an environment, there is a possibility that several simultaneous applications could try to access the same data files simultaneously. This could possibly cause problems if one application is trying to update a file while other applications are accessing it.
