We suggest in this paper that voting in political systems can be profitably analysed using complex system analysis. We discuss how we can capture the complexity of voting behaviour by applying graph theory in networks and we develop a simplified theoretical model of voting choice adopting the...

Forest management aims at building ecological networks that minimize the impacts on timber production. We formalize the construction of ecological networks in forest environments as the optimal control dynamic graph-theoretic problem. The ecological network is based on a set of bioreserves and...

We introduce Stochastic Flow Diagrams (SFDs), a new mathematical approach to represent complex dynamic systems into a single weighted digraph. This topological representation provides a way to visualize what otherwise would be a morass of equations in differences. SFDs model the propagation and...

A large portion of Macroeconomic and Financial research is built upon classical applications of Linear Algebra (such as regression analysis) and Stochastic Calculus (such as valuation models). As a result, most Macroeconomic and Financial research has inherited a focus on geometric locations...

Cluster analysis has become a popular instrument in determining the innovativeness and competitive power of national and regional economies. A wide variety of methods have been employed by researchers to identify the key industrial clusters in a regional economy. This paper reports the results...

The minimum weighted dominating set (MWDS) problem is one of the classic NP-hard optimization problems in graph theory with applications in many fields such as wireless communication networks. MWDS in general graphs has been showed not to have polynomial-time constant-approximation if <InlineEquation ID="IEq1"> <EquationSource...</equationsource></inlineequation>

This article reevaluates the impulse response functions (IRFs) to a monetary policy shock of the structural vector autoregression (SVAR). Identifying restrictions are specified and justified based on empirical evidence,i.e., conditional independence relations of variables, which is an important...

This paper presents a procedure for decision analysis in water use conflicts among irrigators. It seeks feasible compromise term among decision makers by using optimal results for different proposals of solutions. The process is developed by applying the Graph Model for Conflict Resolution. The...
