The purpose of this study was to evaluate the suitability of using an existing 25-ft radius centrifuge as a dynamic flight simulator for “full mission” F/A-18 strike fighter mission training with respect to the representativeness of pilot-perceived motion and acceleration cues. The methodology employed in this study consisted of analyzing F/A-18 mission tasks, collecting pilot opinion surveys of important sensory cues needed in simulator training, and conducting an analysis of human pilot perceptual problems caused by centrifuge motion constraints. This study identified a number of issues indicating that a centrifuge-based flight simulator shows limited potential for use in “full mission” F/A-18 training scenarios. Specifically, there is a fundamental mismatch between the 6 degree-of-freedom mission-representative acceleration environment experienced in the aircraft and the 3 degree-of-freedom acceleration environment the centrifuge is able to provide. The centrifuge is not optimized for the typical acceleration environment experienced during F/A-18 missions and has significant limitations in “near one g” and “near zero g” flight conditions. Additionally, the centrifuge causes a variety of undesired, unrealistic, and debilitating vestibular artifacts that are not consistent with what a pilot experiences in the aircraft when performing the same mission task, degrading the effectiveness of training. Despite its limited suitability as a “full mission” F/A-18 simulator, the centrifuge is an essential physiological training device, shows good potential as a part-task trainer for departure/spin training, and should continue to play a role in the F/A-18 training continuum.

The purpose of this research is through building a System Dynamics model to show hospital operating structure as a whole and to find out the interactions between variables. And through the Management Flight Simulator to simulate three policy¡X¡§retrenchment personnel policy¡¨, ¡§retrenchment personnel policy and ¡§raising salary¡¨, ¡§abundant personnel policy¡¨¡X to find out the best manage policy. The case in this research is a Regional Teaching Hospital in southern Taiwan. The model is built according to the information which got by many times interview. The model has four sub-systems; they are ¡§market sub-system¡¨, ¡§human resource sub-system¡¨, ¡§equipment sub-system¡¨ and ¡§finance sub-system¡¨. After the simulation and the evaluation, we find that ¡§abundant personnel policy¡¨ can save more cost than ¡§retrenchment personnel policy¡¨. That is because ¡§abundant personnel policy¡¨ not only can save the physical cost like recruiting cost and training cost, but also can save the invisible cost like the experience of employee can¡¦t be accumulated. Besides, raising salary although can slacken off the decreasing employee satisfaction due to the overloading, but it is cure the symptoms, not the disease. In long-term, it will lead to the increasing cost, decreasing the competitiveness.

A Variable Stability Flight Simulator is being developed in the School of Aerospace, Mechanical and Mechatronic Engineering at the University of Sydney, Australia. The device is being developed both as a teaching tool for use in flight mechanics courses in the department and as a research tool. It is reasonable to state that learning is enhanced through the experience of concepts outside of the classroom environment. It is intended that the device will be integrated into the department�s teaching program in aircraft flight mechanics. Initial studies centred around a PC based flight simulation developed at the Cranfield College of Aeronautics in the United Kingdom. This system utilises a distributed architecture with several computers connected via Ethernet. It also employs a Primary Image three channel visual system. The system has been further enhanced by the addition of a Link flight simulator provided by the Royal Australian Air Force (RAAF). The RAAF had been using the simulator as a training tool for some years until it had become surplus to requirements. Most of the work in the project has centred around re-engineering this simulator into a viable research/education tool. The Cranfield system has been incorporated into the Link simulator�s hardware to provide a fixed base simulation. The majority of the work described in this thesis revolved around the re-engineering of the flight control loading and motion systems. Previously these items were controlled by analogue circuitry with minimal digital interfaces to the main simulation software. The systems have been re-designed to replace much of the single model analogue circuitry with re-configurable digital control software. Doing so allows changes to be made to the systems in real time through a software interface. The software resides on a common computer that extensively interfaces with the rest of the simulation. To support the hardware involved and to provide for system operation and safety, an extensive Supervisory system has also been implemented. This system along with the motion and control loading software has been implemented in the Matlab / Real-Time Workshop environment. This gives the capability of making real-time changes to any part of the overall simulation. A variable stability module (vsm) is under development. The addition of this module will allow changes to be made to the simulation itself in real-time. The simulator is now functional with the motion and control loading systems operating as designed. Tuning of both systems has been done subjectively by the author. An initial objective analysis of the motion system has been undertaken in an attempt to verify the fidelity of the motion cues generated. A significant outcome of this project has been to create a safe, easily maintainable, re-configurable flight simulator from a large, complex, legacy system. The facility now forms a significant research and teaching tool in areas such as flight mechanics, propulsion, aircraft handling qualities and human factors.

This research is an empirical study on the kind of special restaurants, aiming at understanding the growth strategy in food and beverage industry by means of system dynamics and building the management flight simulator for the research object. Based on several times of interviewing an Italian restaurant, the research model is built and composed of five major parts, which are ¡§Subsystem of customer and market,¡¨ ¡§Subsystem of employee,¡¨ ¡§Subsystem of capacity,¡¨ ¡§Subsystem of service quality and satisfaction¡¨ and ¡§Subsystem of finance.¡¨ Under the property of low repurchasing in this kind of restaurant, conclusions below are found after policy simulating: 1. Strategy of high-price with high-cost is suitable for this kind of restaurant¡¦s long-term management. Though the cost is higher, high-price strategy results in high customer satisfaction. With high revenue and steady customers, the possibility of insufficiency of growth and investment decreases. 2. Even if a restaurant has high customer satisfaction and sufficient capital, growing too fast will fail it easily. Growing too fast will fail a restaurant because of insolvency, especially the kind of special restaurant, of which the frequency of patronage is not as high as that of common restaurants. Therefore, quick expansion will bring out huge expenditure; thus, fails a restaurant even if there is high service quality and high satisfaction. 3. Advertisement makes future customers patronize earlier. Maintaining frequent customers is a better strategy. Advertisement makes future customers patronize earlier, but its effect does not last as long as word-of-mouth effect. 4. Business environment is better when all competitors compete with each other by means of high-price strategy. By adopting low-price strategy, a restaurant will draw lots of customers and need to expand itself. Quick expansion, however, reduces customer satisfaction and leads to fail eventually. Instead, managers who adopt high-price strategy run business better. As a result, business environment is better when market players adopt high-price strategy.

This article is about building a dynamic model of an Italian food restaurant in Kaohsiung, Taiwan. The model contains six sectors, including human resource sector, kitchen sector, quality sector, training sector, market sector and the financial sector. Depending on these six sectors we build a computer simulation model. With this computer simulation model can help people get better understanding of the real operational system and can have better insights of the restaurant management. In this article, we found out that the restaurant manager needs to emphasize the quality and training of their employees. If the restaurant grows without enough qualified employees, the growth will meet its limit and has problems like quality decline, working overtime, high turnover rate, customer base decline and may cause the restaurant to close up. In this article, we also found out that the training must both emphasize the professional training and ethic training and it is better to emphasize a little more on the ethic training. If the restaurant managers focus only on the professional training, it will bring serious problems. Since it has many conflicts during the work, the ethic training can help employees having more stable, social emotions for better customer service and build a trust and harmonious working atmosphere. Otherwise, the conflicts between the coworkers may cause service delay, service mistakes, increasing cost and high turnover rate. All these problems will affect the operation of the restaurant management in long term. In this article, the dynamic model contains many soft variables of the restaurant management. It can provide the learner of dynamic model building to learn about the soft variables modeling.

This research tries to observe an advertizing printing company¡¦s business model and understand the interaction between different policies implemented on the company by System Dynamics. Futhermore, building Management Flight Simulatior can let one simulate the situation and policies to find the effective policies. After the simulation and the evaluation, we find that if the company only pays attention to marketing but didn¡¦t make efforts on the employees¡¦ training, it will block the company¡¦s growth, and the manager always ignored this problem. However, if we only make efforts on training the employees or hiring new employees, it will be just a waste of money in the long run. Therefore, the manager should enlarge his thinking boundary, and considerate not only marketing but training, and even many other policies, and the most important is their interaction, at appropriate time.
