This diploma thesis is focused on cost index. Cost index is one of the method, which is used for cost optimalization in airline operation. Cost index compare time-related costs during flight and cost of fuel. Value of cost index influences cruise speed and fuel consumption, the higher cost index, the higher speed. Costs classification into fixed, variable and time-related costs is very important for cost index calculation. Goal of thesis is decribe importance of using cost index and advantages resulting from correct cost index application in airline operations. Practical part is focued on fuel consumption of Boeing 737 on specific routes and its evaluation. The goal is to compare calculated and real fuel consumption and find, if an airline is able to achieve calculated consumption in real operation.

Sustainability has been heightened to a new level of importance, due to the current global race for commodities and conservation of our environment. Sustainable Buildings are of particular interest since buildings are significant contributors to consumption of resources. Since the inception of the United States Green Building Council (USGBC) in 1993, USGBC has played a key role in providing guidance to the design and construction community in building“green" structures. The Leadership in Energy and Environmental Design (LEED) rating system is an industry accepted standard for the design/construction and measurement of green buildings. Although USGBC provides guidance on performance measurement, a streamlined process of performance tracking and measurement has not been formalized. This research focuses on identifying vital areas of required tracking and measurement; to allow for a systematic analysis of costs and benefits, over the life of sustainable buildings. A case-study based on the recently designed and constructed East Hall LEED-Gold Certified, dormitory building at Worcester Polytechnic Institute (WPI), was undertaken to create and assess a life cycle costs analysis framework. This research is aimed at understanding what the costs of building green at WPI truly are. Life Cycle Cost Analyses of the mechanical, electrical, plumbing and roof components were evaluated to generate percent savings or percent added cost. This research reviewed the various green and non-green costs of construction, consumption, and operations and maintenance costs providing a comparative analysis to leading researchers in the field of costs and benefits of building green.

This thesis deals with the collation of the automotive and wheel tractor transport system with interchangeable superstructures and their use in the business of primary agricultural production in terms of technical parameters, analysis of the use of individual bodies, analysis of investment and operating costs and by comparing the two systems on the basis of the identified parameters. Comparasion was the truck Tatra Phoenix 158 with the superstructures for the transport of powdery and bulky materials, spreaders, manure spreaders and superstructure designed for the transport of heavy materials with tractors transport system John Deere 8320 and tandem semi-trailer Fliegl with manure and conveyor superstructure ASW 268 in the Agricultural cooperative Cizova. In the performance collation of both systems when transporting silage and achieve the highest mass performance at the tractors transport system and it 14,39 t.h-1 which is aganist automotive system less about 5.94 t.h-1. On the other hand fuel consumption to distance traveled, weight and the cycle was recorded the lowest consumption of the lorry Tatra. The economic collation showed that the truck Tatra Phoenix 158 has a lower cost on the distance travelled, the transported amount of cargo and per tonne-kilometre compared to tractors transport system. The cost of the distance travelled makes 90,24 CZK.km-1 which is beside tractor system lower of 100 CZK.km-1. The value of the cost of the transported amount of cargo by lorry moves on 92,10 CZK.t-1 but tractor system has this value lower of 24.83 CZK.t-1.The lowest difference between the costs experienced in the evaluation of the cost per tonne-kilometre where the truck Tatra reached the cost of 9.42 CZK.tkm1 which is compared with tractors transport system, the lower of 3.28 CZK.tkm-1.

This diploma thesis deals with the problem of operating costs analysis and their evaluation on the bus line No. 49 provided by Brno transport company. The first part is focused on history and current status of the Brno transport company. In the second part the route of the bus line No. 49 and technical parameters of Crossway Low Entry bus are further specified. Finally the thesis describes all costs to ensure the operation of this line.
