An approach to measuring developers statistically is prosented in the course of constructing FSEPM(formal software evolution process model)by drawing upon the X-S charts.

The paper addresses an efficiency measurement and an improvement strategy for the Formal Software Evolution Process Model(FSEPM).

With the thought of developing a space debris environment evolutionary model, the process of developing the model is studied.

Based on the Nelson & Winter evolutionary model,it is proved in this paper that the relationship of innovations and regulations with market structure and industrial effectiveness is interactional.

Network traffic flow evolution model considering OD demand mutation

A dynamic evolution model on industry agglomeration based on swarm intelligence was provided with computer simulation,with the result that the accumulation and diffusion of knowledge was the prime motivation of industr.

Based on the parabolic relation between peak stress and SR strain, and the linear relation between ratcheting stress and temperature, the saturated ratcheting evolution models at room and elevated temperatures were presented by using single-specimen m.
