In General, a complex real-time system is made up of multiple concurrent members of timed automata. To verify the safety and liveness of real-time system, model checking always use reachability analysis to accomplish. The existing reachability analysis algorithm can be divided into two types: semi- symbolic based on difference bounded matrices (DBM) or equivalent time region map and the full-symbolic...
Reach ability analysis algorithm is the foundation of model checking. State space explosion is accelerated due to the time constraints of timed automata, therefore, the complexity of reach ability analysis algorithm has increased. The existing timed automata reach ability analysis methods can be divided into two types: the first type is the state space traversal algorithm based on equivalent time...
Energy saving and emission reduction (ESER) has caught attention around the world due to the severe environmental challenges. An Evaluation System to assess the consumption and emission of a product during its life cycle is proposed in this paper. The system integrates with the enterprise information systems by adding the consumption and emission data into BOM(bill of material). Based on ESER database,...
Abstract-The differences of industry in space allocation are caused by factors and its mobility. Based on empirical analysis of inner-provincial panel data, our results are that fixed capital and human capital have an impact on the agglomeration of information service industry, while entrepreneur and the quality of the population have a very significant impact especially on enhancing the agglomeration...
This paper proposes that double level programming technique may be adopted in synthesis strategy. Optimization of heat exchanger network (HEN) structural configuration (i.e., the master problem) maybe solved at the upper level, leaving the rest operating conditions(i.e., the slave problem) being optimized at the lower level. With the uniqueness in mind, a HEN synthesis expert system may be applied...
