Recently, teaching-learning-based optimization (TLBO), as one of the emerging nature-inspired heuristic algorithms, has attracted increasing attention. In order to enhance its convergence rate and prevent it from getting stuck in local optima, a novel metaheuristic has been developed in this paper, where particular characteristics of the chaos mechanism and(More)
Marine plastic debris is becoming increasingly serious marine pollutant. Based on the comparative positions of marine of plastic debris and marine current movement and in order to describe and comprehend the extent, density and distribution of the plastic debris in the gyre, the cellular automata model was introduced to analyze the marine plastic debris(More)
This paper establishes a Volterra predator-prey model with three biological populations, and specify the steady-state numbers of the three populations. Then, based on AHP, obtain the ratio of different species in the second population. When other species are not totally suppressed, with an improved predator-prey model we simulate the current situation to(More)
Water quality evaluation is an important basic work for the water environmental management and protection. This paper presents a new water quality monitoring method based on principal component analysis-wavelet neural network combined model. First, the establishment of water quality evaluation index system, and then using principal component analysis to(More)
Coal three-tier supply chain system consists of several suppliers, manufacturers and retailers. This paper establishes the supply chain system model base on analysis subsystem membership, analyze and optimists the supply chain system model with Tabu Search algorithm. Finally, many examples show the model and algorithm is feasible and effective. Base on the(More)
This paper established a bin-packing model according to file preservation problems, which is a NP hard problem, the paper use FF and FFD algorithm to obtain the corresponding results, by comparing the results, with the bound theory of the optimal solution to prove the obtained solution from FFD algorithm shall be the optimal solution. This paper further(More)
