Displacements back analysis in soft pit excavation is a key issue for design. In this paper firstly the five-component soil model is presented to simulate mechanical process of soft soil, and the finite element code is developed. Secondly the model of displacement back analysis is set up. Thirdly the genetic algorithms is adopted to solve the model of displacement back analysis, and the code of displacement back analysis for soft pit excavation based on the genetic algorithms (DB-EV-GA) is developed. Lastly a case study is performed. Our main findings are: (1) The displacement of the pit engineering in soft soil increases with the increment of time. The five-component model can simulate the effect;(2) The displacement back analysis method based on the genetic algorithm presented in this paper is effective, and the calculation displacement data are near to the observational data in case study.

To enhance the running efficiency of elevator group control system (EGGS), the paper presented an optimal fuzzy dispatch strategy based on traffic flow mode. The paper explored the Characteristic of EGCS, discussed the superiority of fuzzy control for dispatch assignment, studied the traffic flow mode, presented the evaluation index system and its evaluation standard, constructed the algorithm model, gave an algorithm flowchart for elevator group dispatch, and made the simplified experiment simulation. The simulation results show that it is reasonable and feasible, higher in running efficiency, and better in energy saving.

To solve the puzzle of multi-parameter optimization problem of intelligent controller, the paper proposed an immune-genetic principle based optimization method of multi-parameter controller. Inspired by biology immune principle, firstly it was defined to some concepts such as antibody, antigen and affinity of the parameter optimization problem. Secondly the immune based optimization process of parameter tuning was depicted in detail. Then it took the parameter timing of human simulated intelligent controller as an example to make the digital simulation for complex system. The simulation result showed that it is better in control quality than other PID tuning method to the intelligent controller, and more suitable for solving the control puzzle of complicated object.

Based on the comprehensive analysis of hazard factors and evaluation indexes in gas stations, gas station safety is assessed in a fuzzy synthetic evaluation approach using the analytic hierarchy process, fuzzy transformation theory and the principle of maximum degree of membership. Through comprehensive evaluation, the specific safety level of gas stations could be determined. The results show that the fuzzy synthetic evaluation approach takes various factors that affect the system into account and gets a better result. Based on the above research conclusion,which provides a theoretic and practic base for other enterprises in the safey assessment.

This essay introduces the concepts of knowledge granularity and information systems. On this basis, we propose two new more general knowledge granularities: the combination granularity and polynomial granularity, which include the current common knowledge granularity. The results for the establishment of granular computing in the complete information system have some theoretical significance and practical values. In addition, we also discuss the digital feature about knowledge divided and the relationship between it and knowledge granularity.

Information systems integration project is based on shared mental model, while it's difficult because of different profit and cooperation condition. Introduce knowledge complementary as another factor that makes influence on shared mental model into traditional four factors taking account of the high intensive knowledge in information systems integration. Then we analysis the connection among these factors on system dynamic review, and built up knowledge accumulation model and calculus this model with two-phrase game theory. According to this, test that knowledge complementary give influence on shared mental model.
