An analysis of the potential formalism, used in the hierarchical system theory is performed, addressing the autonomic computing system design. In that manner, self management of the overall autonomic system can be achieved by influencing the local resources and the goals of the local computing subsystems. Thus, a quantitative formalization of the control… (More)
—In this paper a short chronology of evolution of workflow management systems is given. Classifications according to different criteria of software tools supporting modeling and execution functionalities of workflow management systems are presented.
Noniterative coordination strategy is extended to the case of coordination with prediction. It is applied for optimal resource allocation in a two level system. Appropriate model for steady state optimization is derived.
This paper applies a bi-level formalism for the optimal control of an urban transportation network. The well known store-and-forward model in traffic control is utilized in order to increase the control space of the optimization problem. Mainly, the store-and-forward models apply the split as a control argument, assuming the traffic light cycle as a… (More)
