The cost of extending airconditioning hours has been dramatically lowered. YOY (%) – Right column Consumption (kwh)－Left column Estimate of the Profitability Improvement ? Power consumption has been lowered by % from the ’02 data (’03 August – October average). ? Extension cost of airconditioning hours has been reduced by % (’03 August – October average). ? Applying these reduction ratio to the full year cost of ’02, we would get the following cost improvement. Power cost： $16,970（Excluding fixed charge/ ’02 total: $180,600） Extension cost of airconditioning：$67,890（’02 total: $133,400） Total：$84,860 （% of the ’02 total: $314,000） $1= Yen/ 682: ’02 – ’05 Average +) Control IMR Chart （’02 Jan.～’ 03 Oct.） ? The process will be controlled with IMR charts for power consumption ( of days adjusted) and the YOY % of airconditioning cost for extra hours. 1 0987654321S u b g r o u p 09 5 0 0 09 0 0 0 08 5 0 0 08 0 0 0 0Individual ValueM e a n = 8 7 6 5 6U C L = 9 4 4 9 2L C L = 8 0 8 1 91 0 0 0 05 0 0 00Moving RangeR = 2 5 7 1U C L = 8 3 9 9L C L = 0I a n d M R C h a r t f o r C 1Power Consumption IMR Chart YOY % of Extra Airconditioning Cost IMR Chart 1 0987654321S u b g r o u p 02 0 01 0 00Individual Value1M e a n = 7 9 . 2 6U C L = 1 7 7 . 0L C L =
