Determining the Proper Number of Software Licenses

Abstract:

Software houses sell their products by transferring
usage licenses of various software components to the customers.
Depending on the kind of software, there are several different
license types which allow controlled access of services. Two most
popular types are single-user license which gives the access rights
for an identified workstation and institute-wide license which
restricts the number of simultaneous users to a fixed limit.
The latter of these types is advantageous when the users do not demand
full-time services and occasional lack of access is bearable.
The problem of deciding the number of institute-wide licenses is
studied in the present paper. Based on the expected usage profile
of the software, we calculate the minimal number of licenses which
guarantees that the customers get a service better than a given
lower limit. The problem is studied by using both queuing theory and
simulation. Results of the study may be used for setting the license
prices and for determining the proper number of licenses.
