This paper presents PLCTools, a formal environment for designing and simulating programmable controllers. Control models are specified with IEC FBD (Function Block Diagram), and t...
Correct synchronization among activities is critical in a business process. Current workflow languages such as BPEL specify the control flow of processes explicitly. However, thei...
In order to support the conceptualization and specification of simulation models of complex systems, several formalisms or world views exist. Petri nets, differential equations, d...
Due to computational intractability, large scale coordination algorithms are necessarily heuristic and hence require tuning for particular environments. In domains where character...
High availability (HA) computing has recently gained much attention, especially in enterprise and mission critical systems. The HA is now a necessity that is no longer regarded as...
