Generally speaking, wafer fabrication factories define the photolithography area as the dispatching center of the entire factory. To establish a set of operative dispatching rules in the photolithography area while taking into consideration the rework of defective products would assist in coordinating and balancing the workload of the entire production line. Furthermore, it would help to enhanc...

Handset and channel mismatch degrades the performance of automatic speaker recognition systems significantly. This paper enhances the feature mapping technique by proposing an iterative clustering approach to context model generation which offers an improvement in the performance of feature mapping trained on labelled data and offers the potential to train feature mapping in the absence of corr...

Previous research suggests that an eventual information technology (IT) success depend on both its initial adoption (acceptance) and subsequent continued usage (continuance). Expectancy disconfirmation theory (EDT) has been successfully used to predict users intention to continue using information technologies. This study proposed a decomposed EDT model to examine cognitive beliefs and affect t...

The railway system is vulnerable to disruptions that require careful management of available infrastructure capacity in order to keep operations feasible and attractive for passengers and for the environment. Dispatchers manage traffic with a limited view on the network impact of their actions. Effective large scale dispatching solutions are required to better forecast the delay propagation in ...

Flexible manufacturing systems (FMSs) are advanced and highly integrated manufacturing systems consisting of robots, machining cells, and automated guided vehicles (AGVs) that function under the hierarchical control of computers. The relations between its components are very complex. Scheduling in FMS is an intricate phenomenon owing to the large variability in the operating parameters. Schedul...

We design a dispatching controller for elevator systems during uppeak passenger traffic with the ability to adapt to changing operating conditions. The design of this controller is motivated by our previous paper where we proved that for a queuing model of the uppeak dispatching problem a threshold policy is optimal (in the sense of minimizing the average passenger waiting time) with threshold ...

This paper presents an energy-aware workload dispatching simulator for heterogeneous clusters. Most clusters in a data center are composed of different kind of machines. Among these machines, the front-end nodes distribute incoming requests to the back-end workers. The main concern in such system traditionally focuses on computation performance, but energy consumption has emerged as an equally ...

BACKGROUND Acute allergic reactions often occur in out-of-hospital settings, and some of these reactions may cause death in the short term. However, initial diagnosis, management and processing of acute allergic reactions by Medical Emergency Dispatch Centres are not documented. The aim of the present study was to describe acute allergic reactions and their management by a Medical Emergency Dis...

A common way of dynamically scheduling jobs in a manufacturing system is by means of dispatching rules. The problem of this method is that the performance of these rules depends on the state the system is in at each moment, and no one rule exists that overrules the rest in all the possible states that the system may be in. The system’s state is defined by a set of control attributes. It would t...

Job shop scheduling (JSS) problems are optimisation problems that have been studied extensively due to their computational complexity and application in manufacturing systems. This paper focuses on a dynamic JSS problem to minimise the total weighted tardiness. In dynamic JSS, jobs’ attributes are only revealed after they arrive at the shop floor. Dispatching rule heuristics are prominent appro...
