The proposed business valuation system of RFID companies is depicted in Fig 1. It consists of the following modules: key factors, profit forecasting, and business valuation. In the first module the key external and internal factors affecting the company profitability are identified. In the second module, IBFOA is designed to find communities in NG and ECMM is developed to forecast the company profit. Business valuation module assesses the value of RFID companies according to the forecast results of ECMM, which gives a full consideration on the investment opportunity value of the RFID companies.
