An efficient and accurate prediction of a precise tidal level in estuaries and coastal areas is indispensable for the management and decision-making of human activity in the field wok of marine engineering. The variation of the tidal level is a time-varying process. The time-varying factors including interference from the external environment that cause the change of tides are fairly complicated. Furthermore, tidal variations are affected not only by periodic movement of celestial bodies but also by time-varying interference from the external environment. Consequently, for the efficient and precise tidal level prediction, a neuro-fuzzy hybrid technology based on the combination of harmonic analysis and adaptive network-based fuzzy inference system（ANFIS）model is utilized to construct a precise tidal level prediction system, which takes both advantages of the harmonic analysis method and the ANFIS network. The proposed prediction model is composed of two modules： the astronomical tide module caused by celestial bodies’ movement and the non-astronomical tide module caused by various meteorological and other environmental factors. To generate a fuzzy inference system（FIS） structure,three approaches which include grid partition（GP）, fuzzy c-means（FCM） and sub-clustering（SC） are used in the ANFIS network constructing process. Furthermore, to obtain the optimal ANFIS based prediction model, large numbers of simulation experiments are implemented for each FIS generating approach. In this tidal prediction study, the optimal ANFIS model is used to predict the non-astronomical tide module, while the conventional harmonic analysis model is used to predict the astronomical tide module. The final prediction result is performed by combining the estimation outputs of the harmonious analysis model and the optimal ANFIS model. To demonstrate the applicability and capability of the proposed novel prediction model, measured tidal level samples of Fort Pulaski tidal station are selecte

＜正＞To improve economy benefit of quarry enterprises, it should take information industry development and numeric management road. Mining scheduling system is taken as a main craft system of quarry producing scheduling system, its real time modeling and real time optimization of mining scheduling system will become an important task for quarry information management. This paper has constructed mining scheduling system model of cement material quarries with adaptive network-based fuzzy inference system（ANFIS）, which has been solved by parallel genetic algorithms（PGA） subject to market demand, producing craft, quarry quality etc. Namely it can schedule drilling equipment and adjusting its mining parameter of each platform by hybrid intelligent optimization technology and global position system （GPS） technology based on ANFIS and PGA. It is not only to set up a new ideal for real-time optimization problem of mining scheduling system, but also it provides theory innovation for optimizing drilling-blasting parameter, in the meantime, it provides importance reference value for quarry production scheduling system for going for information, intelligent, aggregate and system etc.
