Dynamic programming value iteration can be made more ef cient on speci c networks by characterizing the transient and “insensitive” states. These methods are demonstrated by nding the optimal policy for a ve-machine series make-to-stock line with machine failures. State space truncations are chosen by checking the recurrent class in previous runs. An approximate model is developed that reduces ...

In this paper, we investigate the advantages and disadvantages of a proposed decentralized Air Tra c Management (ATM) system, in which aircraft are allowed a larger degree of autonomy in deciding their route ("free ight") instead of following prespeci ed "sky freeways". A decentralized management scheme is described, which incorporates a hybrid control system switching among di erent optimal co...

Failures of fiber links can result in major loss of data in high speed optical communication networks. Survivability is of critical importance and assuring high levels of availability becomes an important issue. A typical approach to the design of resilient optical networks is through protection schemes that pre-determines and reserves protection resources considering single and double link-fai...

Two phenomena can produce chattering: switching of input control signal and the large amplitude of this switching (switching gain). To remove the switching of input control signal, dynamic sliding mode control (DSMC) is used. In DSMC switching is removed due to the integrator which is placed before the plant. However, in DSMC the augmented system (system plus the integrator) is one dimension bi...

This paper interprets economic growth as a sequence of transitions between four growth regimes: crisis, stagnation, stable growth, and miracle growth. Countries experience distinct patterns of growth because they switch between the growth regimes with different frequencies. The aim of this paper is to identify countries with similar growth dynamics in order to determine the driving forces behin...
