In this context, capacity optimization goes beyond the traditional aim of capacity maximization, contributing also for organization's profitability and value. Indeed, lean management and continuous improvement approaches suggest capacity optimization instead of maximization. The study of capacity optimization and costing models is an important research topic that deserves contributions from both the practical and theoretical perspectives. This paper presents and discusses a mathematical model for capacity management based on different costing models (ABC and TDABC). A generic model has been developed and it was used to analyze idle capacity and to design strategies towards the maximization of organization's value. The trade-off capacity maximization vs operational efficiency is highlighted and it is shown that capacity optimization might hide operational inefficiency.

Using wind power to produce electricity is a perfect fit. Because wind energy has become the least expensive source of new electric power that is also compatible with environment preservation programs many countries promote wind power technology by means of national programs and market incentives. Also it provides an effective solution for reduction of fossil fuel consumption and pollutant emissions. The wind turbines are used for the generation of wind energy, simple in construction, economical and which gives appreciable output. Wind shear is one of the major factors affecting the working of wind turbines. Vertical shear, or the change of winds with height, either enhances or diminishes the vertical draft strengths. Input parameters and output parameters vary with different turbines. Flicker voltage is one of the major parameter concerned with the wind turbine parameters. Voltage flicker are caused due to heavy loads periodically turned on and off in a weak distribution system. This paper presents the effect produced in the output voltage and flicker voltage due to vertical wind shear in conventional type of wind turbines. The objective of this paper is to introduce the assessment parameters of the wind energy production of sites and pairing between the sites and wind turbines.

The ice accumulated on the wind turbine blade is removed by dielectric heating. High frequency supply is used for heating. The metallic plates are embedded in the wind turbine blades when the blade is being manufactured. The metallic plates are separated by the insulation medium. The plates are completely coverd by the insulating material. This construction also enhances the strength of the wind turbine blade due to reinforcement by the metallic plate. The supply is given to the blade capacitor when the ice is accumulated. The ice is sensed by ice sensor. The supply to the capacitor may be given by the battery bank. The wind turbine is stopped when the ice is being removed by dielectric heating. The area below the wind turbine is vacated. The human beings and animals are not allowed to go near the turbine as the ice may fall below and the person or animal may be injured due to ice.

In the test set ups there is a provision of sea sand, river sand, river pebbles of various sizes, grass, building models of various heights, hills models of various heights and slopes and offshore environment with artificial water waves is available.

The offshore environment can be created by using a tray of water at the bottom of the test set up. Artificial waves of water are created by a motor coupled with four longitudinal cups welded together and mounted on a shaft. Because of this continuous waves are produced. Another method of producing waves is that use a surface with inverted V all along the surface. The water is needed to move continuously with the help of a pump. This will also create the waves. The impact of wave height on flicker will be observed. For the surface of grass actual grass tiles may be fixed on the surface of the wind turbine test set up.

Hot water is used to remove the ice accumulated on the wind turbine blades. The pipes are embedded in the wind turbine blades. The pipes which are embedded may be made up of copper or steel or any other thermally conducting material. The water pipe is connected to the blade from the water tank placed at the ground. The water is heated by water heater. The water heater may be an electric heater. The water may also be heated by gas geyser. The water pump is used to circulate the water from the water tank to the wind turbine blades. When the water pump is started it circulates the water through the water heater and the wind turbine blades. The pump keeps the water circulating through the wind turbine blade until the ice melts and falls down. In the environmental conditions favorable for ice accretion on the wind turbine blades, the pump circulates water through wind turbine blade after frequent intervals of time to prevent ice accretion on the wind turbine blades.
