Traditionally, the prearrangement of the maintenance manpower supply in accordance with the scheduled maintenance tasks is been based on staff experience and been performed manually which is time-consuming as well as an ineffective criterion. Therefore, formulating an optimized framework with the purpose of allocating the right amount of workforce in the right combination of skills and experience levels to eradicate any shortfalls or surpluses is essential for the continuation of efficient and effective maintenance in any organization. Hence, this research mainly aims at devising of a manpower-planning model for the aircraft maintenance industry. Sri Lanka Air Force and Sri Lankan airlines that are the predominant aviation operators of the country reviewed as case studies in identifying the correlation between maintenance manpower requirement with respect to aircraft flying hour demands. In order to ascertain intended outcome, interdependency between an aircraft total maintenance deployment, its operational flying ratio would have identified, and subsequently the maintenance friendliness factor for the individual aircraft type would have determined. The ultimate result of this research would provide a solid framework to eradicate disparities between the current available and the actual required manpower quantities for maintenance events. Moreover, the proposed model would facilitate the aviation industry in solving capacity-planning issues related to manpower scheduling and requirement, and to find feasible roistering and task scheduling of shift workers that minimize peak fatigue while satisfying their days off demands.

Written by experienced U.K. and U.S. based authors this is a unique resource that opens up the initial design process, explores the experience of others on similar projects, and clarifies the processes that are behind the equations and calculations used in aircraft design. Armed with this knowledge, readers will be freer to concentrate on the innovative and analytical aspects of their own project work. Key features include: demonstration of how the basic design process can be successfully applied to a wide range of aircraft; highly illustrated case studies that provide a valuable teaching and learning tool, examining how others have approached particular design challenges; and coverage of commercial, military, and concept aircraft design, plus award winning student projectsthat offer an insight into the conceptual design process from the student perspective.

Wayne Storr has created a very good set of tutorials, ranging from DC- and AC-Theory over the basic devices Resistor, Capacitor, Inductor and Diode to Transistors and Operational Amplifiers and to circuits like Amplifiers, Oscillators and Waveform Generators and Filters. Digital topics are also covered, ranging from the Binary System, Boolean Algebra, Logic Gates to Combination Logic, Sequential Logic and Counters.
Each tutorial consists of about 5 to 15 consecutive pages which should be read one after another. The tutorials are independent of each other, but if you are new to electronics you might find it useful to look at them in the order in which I have listed them in the last paragraph. On the homepage the tutorials are listed in alphabetical order, but going through them in that order does not make much sense.
The tutorials do not assume prior electronics knowledge of the reader. For a few pages of the tutorial, the knowledge of a bit of mathematics would be useful, for example in the DC-Theory tutorial the advanced methods of circuit analysis require linear algebra. But even without this you can understand most of the tutorial. The AC-Theory tutorial contains a good explanation of the necessary trigonometry, and also of complex numbers (for a more in-depth treatment of this topic, please take a look at the resources on my Complex Numbers page).
If you work through the tutorials you will quickly gain a good basic knowledge of electronics. But if the pace of the tutorials is too fast for you, try Lessons In Electric Circuits (allaboutcircuits) by Kuphaldt - it will take more time to work through them, but they might be easier for the absolute beginner. By the way, the allaboutcircuits forum that is associated with Kuphaldt’s book, is a very good place to ask if you have questions about any topic in the tutorials.
Storr is also writing a Blog that contains some additional topics, some of them a bit more advanced than those that are covered in the tutorials. In some posts he explains questions that readers have emailed to him. It is probably best to look first at the tutorials and then at the blog, if you are hungry for more information.
