"Movable platform" - the idea and energy consumption

This paper presents the application of the concept of moving sidewalks at railway stations (the movable platform) including the calculation of electricity consumption. Particular focus was placed on issue of energy profit and loss in two stages - through the loss (consumption) of energy by using a moving sidewalk at a railway station platform and the profit (reduced consumption) of energy, by the lack of having to start the train, that supports movable platform, from the initial speed of 0 km/h

Simulation study of an agile high-speed machining system for automotive cylinder heads

There is a continuous need within most manufacturing environments for more flexible production equipment, particularly where customer satisfaction and responsiveness promote quality improvement. In this paper, an automated agile manufacturing system that uses high-speed computer numerically controlled (CNC) machines to make automotive cylinder heads is proposed and evaluated by means of discrete event simulation using the ARENA simulator. Two alternative agile system configurations are constructed and simulated to achieve the production target. The simulation shows some significant benefits in using the agile system and demonstrates that high-speed CNC equipment is a viable option for cylinder head manufacture at a production volume of 550 000 units per annum. It is shown that the agile system can provide more flexibility and half the throughput time of the transfer line

The work's results were made obtainable for use in the aviation industry and in specific aviation education programs.Ця кваліфікаційна робота присвячена розробці далекомагістрального пасажирського літака з максимальною вмістимістю 380 осіб. У цьому дослідженні було використано метод порівняльного аналізу прототипів літаків для вибору найнеобхідніших та обґрунтованих параметрів проектування літака. Крім того, були використані інженерні розрахунки для отримання основних геометричних та компонувальних характеристик проектуваного літака. У спеціальній частині цієї роботи презентовано новий механізм для навантаження пасажирського багажу, який має велике значення у зменшенні трудових навантажень на працівників, скороченні часу, необхідного для завантаження та розвантаження, а також підвищенні ефективності роботи у відділенні багажу. Практичне значення цієї кваліфікаційної роботи проявляється у поліпшенні продуктивності та швидкості роботи у відділенні багажу на довгих перельотах. Результати, які були представлені, можуть бути застосовані в навчальному процесі на спеціальностях, пов'язаних з авіацією, а також у авіаційній індустрії

An ergonomic assessment of the airline baggage handler

A material or baggage handler is responsible for loading and unloading baggage and materials from inbound/outbound aircraft flights and transferring the materials to and from the baggage holding and sorting areas and back to the passengers or output source. Baggage handlers work in all types of inclement weather, all over the airport, and in-and-around the aircraft. The baggage handler\u27s job entails repeated lifting pulling, pushing, squatting, twisting, kneeling, and stretching of the arms and back, which makes the baggage handler\u27s job one of the more challenging material handling jobs to ergonomically assess and make corrections for. The aim of the present study is to evaluate the current literature available pertaining to baggage handlers and ergonomics, as well as examine all aspects of the baggage handlers\u27 job in an effort to develop ergonomic solutions. This thesis is based on the literature review of a core set of articles that thoroughly cover the major aspects of the baggage handlers\u27 job, work environment, and ergonomic afflictions pertinent to the baggage handlers using ergonomic evaluation techniques. It was shown that typical solutions to ergonomic problems of baggage handlers, such as wearing back support belts, are not conclusively effective in reducing the back injury rate amongst airline baggage handlers. The redesign of workstations and aircraft holds, although thought to be the most effective idea due to success where already applied, was not the most practical or readily available solution financially. The future of ergonomic advancements in the field of airline material handling will rely on future research. Such a research will need to develop a benefit analysis to quantify the dollars spent on back-related injuries against the cost of remodeling aircrafts and workstations

Optimization of Cargo Handling Equipment at the Airport

Delaying an aircraft during ground handling costs the airline a lot of money. In critical situations, it is even possible that some flights have to be canceled due to delays. It is therefore the endeavor of all personnel involved in ground operations that they proceed without delay. This paper shows what methods can be used to optimize the required number of handling equipment and what can affect its number

Disrupting Complex Systems with Emerging Technologies: A Study on United States Airport Operations

The number of United States domestic commercial flight passengers are growing every year, which means the number of people checking-in, dropping off their bags, and going through TSA within airports is equally growing. With the increasing number of passengers and aging airports, there are several areas of pain points within airports where passengers hit a bottleneck due to the current systems that airports have in place. There are three main areas that we are going to reference. First the check-in process, where customers have to get their tickets, input identification information, and check-in for their flight. Second, baggage-drop off, where customers get their baggage weighed and tagged. Lastly, is Transport Security Administration (TSA). This is where consumers get their carry-on bags scanned as well as their person. In each of these areas, there are some levels of inconvenience imposed on the customer by the current system. With technological advancements being used in other industries, the goal of this thesis is to look at what existing technologies can be modified and used within airport operations to reduce the long lines that customers face every time they travel

Status - based routing in baggage handling systems : searching verses learning

This study contributes to work in baggage handling system (BHS) control, specifically dynamic bag routing. Although studies in BHS agent-based control have examined the need for intelligent control, but there has not been an effort to explore the dynamic routing problem. As such, this study provides additional insight into how agents can learn to route in a BHS. This study describes a BHS status-based routing algorithm that applies learning methods to select criteria based on routing decisions. Although numerous studies have identified the need for dynamic routing, little analytic attention has been paid to intelligent agents for learning routing tables rather than manual creation of routing rules. We address this issue by demonstrating the ability of agents to learn how to route based on bag status, a robust method that is able to function in a variety of different BHS designs.<br /

Applicability of siberian placer mining technology to Alaska

The result of Perestroyka and Glasnost has been an awakening of potential for cooperation between East and West. Nowhere has that been better demonstrated than between Alaska and Magadan Province, USSR. This report summarizes a one year effort financed by ASTF, with participation from several technical organizations, to establish contacts with the Siberian placer mining industry. The purpose of the project was to provide initial assessment of the Soviet technology for placer mining in permafrost. A ten day trip to Magadan province by an ASTF team and a similar length visit to Alaska by the Soviet mining group representing the All Union Scientific and Research Institute of Gold and Rare Metals, (VNII-I), Magadan are described. The report also reviews translated data on mining in permafrost and describes surface and underground placer mining technology developed by the Soviets. The report also lists relevant publications on Soviet mining research and state of the art Soviet mining technology and expertise
