Considering the uncertainty of information, the paper puts forward an improved grey dynamic programming model. After that, treating profit value as positive interval grey number, the paper researches on dynamic programming model, and we could get the optimal strategy after solution by means of defining standard interval grey number. Furthermore, as we can not make the judgment of standard interval...

According to analyze constituent elements of intellectual capital, the index system was proposed by human capital, management capital, technology capital and market capital, index weights were determined by using AHP, the comprehensive evaluation model was established by using...
In the paper, the k-switching reachability set Rk of a single-input positive switched system is introduced, and conditions for the chain of this sets {Rk; k isin Nopf}, to stop increasing after some finite index k are given. For the special class of positive switched systems, which commute among n single-input n-dimensional systems, sufficient conditions that ensure that the n-switching reachability...
In the multi-objective evaluation process for real estate investment, because of the uncertainty and incompleteness of evaluation information, deciding its gray. Therefore, the gray comprehensive evaluation based on gray system theory has feasibility. In this paper, we establish the gray comprehensive evaluation model of real estate investment according to the impact of real estate investment with...
