Construction of the Structure Function of Multi-State System Based on Incompletely Specified Data

A Multi-State System (MSS) is the type of mathematical model of a system in the reliability analysis in which both the system and its components may experience more than two reliability states. One of the possible approaches of MSS evaluation is based on system representation by a structure function that maps the system components states into the system state/reliability/availability (performance level). But the structure function can be used for completely specified data only. In this paper new method for structure function construction based on incomplete data is proposed. This method is based on the use of decision tree that is inducted according to initial data. A structure function is constructed as decision table that is formed by inducted decision tree.
