Uncertain parameter substantial amounts and relationship be complicated, substantially increases event or parameter itself and between each other information
Fog-level, the single layer subordinating degree function method based on Zadeh fuzzy set and TYPE1 fuzzy set seem clearly disadvantageous,
To be difficult to analyze and handle these fuzzy uncertainty events or parameter in direct analog information.As it can be seen that new energy user point
Cloth photovoltaic generating system day output power calculate the prior art all without comprehensively consideration influence factor uncertainty and with
Machine, calculation method applicability, practicability and application are also difficult to be met.
