Semiconductor wafer fabrication is a very complex manufacturing process. Many semiconductor processes are not very well understood. The control of semiconductor manufacturing processes is, thus, an active research area. Even though various algorithms have been developed for process control and optimization, the scope of application of these algorithms is not very well-characterized due to the c...

Emergency departments (EDs) have been becoming increasingly congested due to the combined impacts of growing demand, access block and increased clinical capability of the EDs. This congestion has known to have adverse impacts on the performance of the healthcare services. Attempts to overcome with this challenge have focussed largely on the demand management and the application of system wide p...

In this paper we treat mathematical and computational models of thermodynamical systems in viscous and diiusive media as optimal information control problems. Under assumption of suucient smoothness on the perturbed Hamiltonian of the system we propose reformulations of the classical problems using the concept of informational limit. In the general situation we use Steklov's operator technique ...

The shorter cycle time (CT) and higher throughput rate (TH) are primary goals of the industry, including sensors and transducer factory. The common way of cycle time reduction is to reduce WIP, but such action may also reduce throughput. This paper will show one practical healthy heuristic algorithm based on tool time modelling to balance both the CT and the TH. This algorithm considers the fac...
