The optimization grouping of experts is one of key problems before making the feasibility study for the momentous project. This paper constructs a mathematic model of...
By using multi-criteria projection pursuit coupling model based on the principle of maximum entropy, multidimensional grey relation analysis values can be integrated into the projection value of single dimension which indicates the advantage of each scheme, so the schemes sample can be optimized according to the projection value of each scheme, the larger it is, the better the scheme is. In order...
Allee effect is strongly related to the extinction vulnerability of populations, but no adequate attention has been paid to this phenomenon in multi-species system. Here, both the strong and the weak Allee effect are introduced into the multi-species competition model to explore the species dynamics in the process of habitat destruction. The results show that: (1) The Allee effect greatly affects...
