This　paper　advances　a　new　method　of　self-organizing　network.　This　method　resolves　the　problem　of　the　SOM　which　can＇t　change　the　number　of　the　network,　and　the　structure　of　the　neural　network　can＇t　be　changed　on-line.　And　this　new　method　combines　with　the　fuzzy　arithmetic,　then　the　fuzzy　rules　can　be　changed　on-line,　it　takes　the　experience　out　of　the　necessary　side　for　the　number　of　the　fuzzy　rules.　The　results　of　the　simulations　prove　the　superiority　of　this　arithmetic　in　the　non-line　systems　approach.
