In this paper, a corresponding particle swarm optimization algorithm is presented to solve the optimization problem of integer resource allocation. This algorithm is easy to programming. Especially, when the total number of resource and departments, profit matrix is changed, we only need to adjust the value of limited parameter in the procedure to get the optimal solution. At last, according the stochastic...
For a three-echelon stochastic inventory system in the supply chain, it is difficult to get optimal inventory control policies by analytical methods. The paper sets up an optimization model, which is built on the basis of the discrete event system simulation theory. The simulation-based optimization method is used to solve the problem by combining the simulation model and the particle swarm optimization...
In order to study the effects of the contract coordination in the supply chain, the complex adaptive system (CAS), Agent model-building and supply chain theories were introduced, and the competitive rules and assumption conditions of simulation of the corporations in the supply chain were described. Then competitive environment of the supply chain was constructed on the Swarm simulation platform,...
The real estate industry has been the pillar industry of national economic. And the high returns and high risks would coexist in this industry. First, this paper established the real estate portfolio model based on information entropy, with the smallest risk as the greatest benefits. In addition, this paper developed a new algorithm to find the optimal real estate portfolio to achieve the smallest...
