Such as SRF(Solid Refuse Fuel) project or incineration plant designed the most basic analysis of waste, and due to the inaccuracy of the forecast construction after completion of facilities proposed in the design phase, the power output and available energy operating costs increased due to the reduction of the amount in the operation phase, If the situation is causing large losses that often occur. In this study, target areas for project more accurate analysis of population distribution by analysis frequency, sampling points and analysis items by manual, samples can be required to represent the area. Also planned waste component of the future target year is based on the results of waste analysis and predict each changes of waste trends, this based on the goal of the year and calculate calorific value through waste composition prediction, the potential amount of energy(the plan of Waste quality) the estimate it is possible to minimize the difference between the actual value of the operating target year.
