Absenteeism prediction and labor force optimization in rail dispatcher scheduling
… labor hours. This can be costly in railroad dispatcher scheduling because every absence must be filled through overtime or a qualified extra dispatcher. One factor that complicates this problem is the uncertainty of unplanned employee absences. The ability to predict unplanned absences would …

An Industry Assessment: Are Aircraft Dispatchers in a Holding Pattern?
… provided an in-depth view of the aircraft dispatcher industry. An assessment of the industry was needed to project the future of the aircraft dispatcher profession, as well as indicate the necessity of additional aircraft dispatcher training facilities in the United States. The position of …

Distributed dispatching for embedded generation
… generators themselves, and others handled by dispatcher software associated with a group of generators and loads. The dispatcher operates a small virtual market where energy can be traded between agents representing: generators, loads, network functions (AVR etc), and other dispatchers. This …

Preliminary development and flight trials of a cruise altitude and speed optimization decision support tool
… tunnel, was developed to aid flight crew and dispatcher situational awareness and decision-making in vertical trajectory planning in order to reduce fuel and time costs. As the optimal altitude for an aircraft changes with speed, weight, outside air temperature, and winds, flight crew …

A distributed CPU-GPU framework for large-scale pairwise alignment
… of the following components: a cluster-level dispatcher, a set of node-level dispatchers, and a set of CPU- and GPUworkers. The cluster-level dispatcher progressively distributes work to the compute nodes and aggregates the results. The node-level dispatchers distribute alignment tasks to …

Policies and Mechanisms for Networked Control Systems
"The second mechanism we present is a ""Message Dispatcher"" (MD) layer for information dissemination in wireless vehicle-to-vehicle communication. The MD enables efficient and flexible transmission of data elements between vehicles. It has been implemented in several vehicles at Toyota, and has …

Short term load forecasting based on hybrid artificial neural networks and particle swarm optimisation
… become vulnerable. This information allows the dispatcher to prepare the necessary corrective actions. The third application of STLF is to provide the system dispatcher with more recent information i.e., the most recent forecast with the latest weather prediction and random behaviour taken into …

Evaluation of a digital communication device for railroad worker safety
… a smartphone to be used by roadway workers and dispatchers that was based in a wireless data link service. The main purpose of using a smartphone in railroad communications is to eliminate errors due to radio and pronunciation deficiencies. Previous studies analyzed the communication environment …

Does Simulation Training Increase 9-1-1 Operator’s Ability to Recognize the Need for Cardiopulmonary Resuscitation Instruction?
… Methods/Design: Analysis was conducted on dispatchers from thirteen call centers who were randomized to receive mock caller scenarios, as part of a randomized controlled study of the use of simulation for training 9-1-1 operators in recognition of cardiac arrest. The simulation consisted on …

Delay, stability, and resource tradeoffs in large distributed service systems
… is conveyed through messages from servers to the dispatcher, and stored in a limited local memory. Our objective is to understand the best possible performance of such systems (in terms of stability region and delay) and to propose optimal policies, with emphasis on the asymptotic regime when both …

Distributed dispatchers for partially clairvoyant schedulers
… scaling up the number of processors used by the dispatcher is also studied. The results validate the superiority of the distributed strategies over sequential dispatching and scalability of the distributed strategies. Certain system limitations which lead to Loss of Dispatchability in the …

Investigating team collaboration in the fire department of New York using transcripts from September 11, 2001
… between responding units and the Manhattan Dispatcher. The goal of this thesis is to use these transcripts to provide a real world example to validate the Structural Model of Team Collaboration, sponsored by the Office of Naval Research. This model focuses on individual cognitive processes …

Design and evaluation of a GPS-aided communication device for railroad workers
… workers try to establish communication with dispatchers at the Traffic Control Center. This problem is expected to grow with the introduction of new rail services. At the same time, roadway worker fatalities still occur every year. Moreover, railroad workers' disorientations also cause …

Implementation of Intermittent-robust Computing on RISC-V Architecture
… saved state upon power resumption; and the Dispatcher, which transparently arbitrates memory bus usage between normal execution and backup transfers. In addition, the instruction set architecture is extended with the .ICA primitive, which allows programmers to define atomic code regions that …

Assessment of the expert locomotive engineer's mental Model through expert-novice interactions
… responding to signals, speed restrictions and dispatcher orders. Each subject pair consisted of one expert and one novice subject. One subject was seated at the controls and the other subject was seated in the conductor's position. The subject at the controls had limited access to information …

The effects of system response time and cognitive loading on accessing an automated telephone emergency service: examining elderly and young users
… avoiding the need for verbal interaction with a dispatcher. The interface was designed in terms of providing the necessary instructions for activation and considering various input strategies and feedback. Icons, written instructions, and voice feedback were employed in the development of a …

Bytes of Evolution : essays on applying social physics lessons for management effectiveness
… to the "optimized" route provided to them by the dispatcher. Traffic congestion, delays at customer sites, familiarity with the customer, and on-site parking led to drivers making decisions that best suited their needs. At the Roskilde Music Festival experiment, we use crowdsourcing to collect …

Onpeak Market Dispatchable Energy From Megawatt Scale Fuel Cells And Stored Digester Methane
… fuel cell systems operated by a spot market dispatcher can provide revenue streams that are double to quadruple the revenue that would be collected from net metered biogas generation. When configured as recommended, these systems can provide up to 38 to 59% of the theoretical revenue from a …

Energy-efficient control of a smart grid with sustainable homes based on distributing risk
… algorithms: 1) market-based contingent energy dispatcher for an electrical grid, 2) a risk-sensitive plan executive for temperature control of a residential building, and 3) a chance-constrained model-predictive controller with a probabilistic guarantee of constraint satisfaction, which can …
