This research applys a fuzzy modeling method based on sampling data to the modeling of cement rotary kiln. By analyzing the sampling data in the actual production process, the mathematical model of the cement rotary kiln calcining system is established using the WM fuzzy modeling algorithm. The modeling method realizes the identification and optimization of the fuzzy rules. The simulation analysis is carried out through the Matlab software. The results show that this method has a high precision. It provides a reference to establish the system's mathematical models.

In order to further improve the efficiency of indoor unmanned transport, a low-power and efficient navigation and positioning system is designed. The system combines the advantages of the detecting method of electromagnetic signals and the indoor positioning technology based on Bluetooth Low Energy (BTLE). By analyzing the magnetic field model, common inductance coils are used as a sensor to detect the magnetic field, and the differential steering mechanism of the motor is controlled by the tracking characteristics of the dual-inductive electromagnetic sensor. For GPS can not provide satisfactory indoor positioning results, on the basis of the electromagnetic tracking system combined with the indoor positioning technology based on spatial information mode, a stable and independent indoor positioning system is finally realized. And with the predetermined electromagnetic track crossing point, the dead reckoning accumulated error for signpost is revised. The experimental results show that the system can achieve stable operation, and the system design is reasonable and basically meets the design goals and users' needs.

Ports played an important supporting role in protecting and driving investment, local exports and regional economic growth hence local governments have accelerated the development and construction of the ports. On the other hand, in order to find its survival and development in such fierce competition, we must enhance ports' vitality and improve competitiveness. In research of how to reasonably and accurately evaluate a port's competitiveness as well as the ways and methods to improve the port's comprehensive competitiveness, for our nation's relevant competent construction department policy, development of the port supply chain management, promoting port resources reasonable allocation, strengthen internal management, all have positive inspirations.
