Voltage stability analysis has been highly concerned by researchers. However, probabilistic techniques cannot handle fuzzy factors in power system. In this paper, a voltage stability analysis method based on adaptive fuzzy logic with consideration of random factors of loads is proposed. System states are classified, fuzzy mathematical model and fuzzy voltage indexes are established, and voltage stability...
Recently, increased attention has been paid to the front end of New Product Development (NPD). In this paper, we report on the key factors for success with regard to the front end activities of NPD in 513 Japanese companies. We develop and test a causal model of relationships among key variables relating to the front end factors and success. The causal model is tested with AMOS using information from...
