The invention discloses a sensor network software modeling platform development method based on a unified modeling language and a genetic algorithm. By combining with the thought of an intelligent agent and the genetic algorithm, a model suitable for sensor network software development is built with the unified modeling language; the built model is optimized by the genetic algorithm; and a modeling platform based on the model is built. A model formed the unified modeling language based on the intelligent agent is built, and by defining a meta-model of a domain model formed by the unified modeling language based on the intelligent agent, the domain model comprises a plurality of diagrammatic figures, namely, an activity diagram of a group, an intelligent agent diagram owned by the group, a group diagram to which the intelligent agent belongs, a role diagram owned by the group and a relational graph between groups. The model is optimized by the genetic algorithm, so that attribute redundancy in the group in the model is lowered, and the model with the perfect performance is obtained. According to the sensor network software modeling platform development method, a purpose that a sensor network software model is visually built is realized, and the sensor network software development difficulty is lowered.
