Mixed Systems

Theoretically, network systems can have numerous structures. In practice, however, only a limited number of them exist, and most of them can be classified into one of those discussed in the preceding chapters, including series, parallel, hierarchical, assembly and disassembly, with only a few left unclassified. Since series, parallel, and hierarchical systems are special types of assembly and disassembly systems, the latter two are the most general ones. The unclassified systems are basically mixtures of the assembly and disassembly ones, which do not explicitly show the relationship between the system and division efficiencies from the viewpoint of efficiency decomposition, although the division efficiencies can always be aggregated, in desired forms, to represent the system efficiency. Once the relationship between the system and division efficiencies is explored, the divisions that have the greatest impact on the performance of the system can be identified. Improvements to these divisions will increase the efficiency of the system the most.
