A framework is introduced for the identification of controls for single-class timevarying queueing networks that are asymptotically optimal in the so-called uniform acceleration regime. A related, but simpler, first-order (or fluid) control problem is first formulated and, for a class of performance measures that satisfy a certain continuity property, it is then shown that any policy that is op...

In this paper we consider a class of mixed optimal control/optimal stopping problems related to the choice of the best time to sell a single unit of an indivisible asset. We assume that in addition to the indivisible asset the agent has access to a financial market. Investments in the financial market can be used for hedging, but the financial assets are only partially correlated with the indiv...

homogenous charge compression ignition (hcci) engines hold promise of high fuel efficiency and low emission levels for future green vehicles. but in contrast to gasoline and diesel engines, hcci engines suffer from lack of having direct means to initiate combustion. a combustion timing controller with robust tracking performance is the key requirement to leverage hcci application in production ...

In this paper, we propose the new concept of optimal solution for fuzzy variational problems based on the possibility and necessity measures. Inspired by the well–known embedding theorem, we can transform the fuzzy variational problem into a bi–objective variational problem. Then the optimal solutions of fuzzy variational problem can be obtained by solving its corresponding biobjective variatio...

A ladder lottery, known as “Amidakuji” in Japan, is a common way to decide an assignment at random. lottery L of given permutation optimal if has the minimum number horizontal lines. In this paper, we investigate reconfiguration problem lotteries. The on set lotteries asks, two L,L? ?, find sequence ?L1,L2,…,Lk? ? such that (1) L1=L and Lk=L? (2) Li for i=2,3,…,k obtained from Li?1 by moving ba...
