At least a part of a communications network is designed beginning with an initial network design, a set of traffic handling requirements and an initial set of design rules. Each rule includes a condition portion and an action portion and at least one such rule includes a portion expressed in terms of at least one variable parameter. An iterative procedure is implemented to evolve both a network design and a set of design rules including variations to rules from the initial rule set. A population of rule sets is generated with each rule set using a different combination of assigned parameter values. For each rule set in the population of rule sets, rules for which the condition portion is satisfied are applied to generate a modified network design. Measures of performance, including cost of each modified design are determined through simulation of the operation of the design on the basis of the traffic handling requirements and the performance and cost of different designs compared. A preferred design then forms the basis for further modified network designs and the particular rule set that generated the preferred design forms the basis of a new rule set population in the next iteration. |
