The paper addresses hierarchical morphological modeling and design of GSM network. The tree-like structure of the system is considered and design alternative (DAs) for each system component (leaf node of the model) are generated. DAs are evaluated upon a set of criteria. Hierarchical Morphological Multicriteria Design (HMMD) approach is used: 1. multicriteria analysis and ranking of alternatives (for leaf nodes of the hierarchical model) to get their ordinal priority on the basis of a common ordinal scale; 2. combinatorial synthesis of composite alternatives while taking into account their priorities (i.e., ordinal quality) and their compatibility (evaluated upon ordinal scale). Electre-like outranking technique is used for multilcriteria ranking. Here Pareto-effective decisions are searching for in a discrete space of system excellence (i.e., quality of elements and quality of their compatibility). Combinatorial synthesis is based on enumerative directed algorithm or dynamic programming approach. The examined hierarchical method for GSM design may be useful in real-world network applications and in education.
