As a new energy project in recent years, biomass power generation is playing a significant role in social and economic life. Recent years, more and more biomass generation projects have been approved, however, some of them are suspending and some are suffering from running troubles. So, it’s very important to build an evaluation system for running and managing such projects. An evaluation system based on the fuzzy synthetic evaluation approach and AHP methods was established in this work, which had been testified effective in practical applications and can be taken as an advisable example of starting and running biomass power generation projects.
