A MODEL FOR MEDIUM-OR LONG-TERM PLANNING

The PDAS(Production Distribution Area,Spatial)is an efficient method for optimalanalysis of the existing industrial production spatial distribution.As the main problem formedium- and long-term programming of the industrial production level isproject investmentanalysis,incorporation of project investment into PDAS to evaluate the project investmentcomprehensively over the whole planned period will be an ideal approach.This.however,changes the linear programming problem into a mixed integer programming problem withconstraints which include a step function.To simplify the algorithm,in light of large scalesystem decomposition,a model and an algorithm with coordinative running of schedulingand distribution optimization are proposed.The new version of PDAS,named PDAS-D,will have more practical use in decision support analysis for the medium-and long-termproduction spatial distribution and optimal adjustment of industrial structure by means ofproject investment.

Attack and Defense Strategies in Complex Networks Based on Game Theory

To investigate the attack and defense strategies in complex networks, the authors propose a two-player zero-sum static game model with complete information which considers attack and defense strategies simultaneously. The authors assume that both the attacker and defender have two typical strategies: Targeted strategy and random strategy. The authors explore the Nash equilibriums of the attacker-defender game and demonstrate that when the attacker's attack resources are not so significantly abundant as the defender's resources, there exists a pure-strategy Nash equilibrium in both model networks and real-world networks, in which the defender protects the hub targets with large degrees preferentially, while the attacker prefers selecting the targets randomly. When the attack resources are much higher than defense resources, both the attacker and the defender adopt the targeted strategy in equilibriums. This paper provides a new theoretical framework for the study of attack and defense strategies in complex networks.
