Benefit-Function Of Two- Identical Cold Standby Communication Satellite System Subject To Failure Due To Inclement Weather Or Failure Due To The Unfavorable Weather Conditions (High Altitude Winds)

Abstract
BENGALURU: Hit by inclement weather, the launch of India's latest communication satellite GSAT-16 was deferred for the second time after it was rescheduled to be put into space in the early hours tomorrow by Ariane 5 rocket from the space port of Kourou in French Guiana. After the satellite launch originally scheduled for today was put off, Indian Space Research Organization had announced that the lift-off would be at 02.09 AM (IST) on Saturday but within hours said it had been postponed again, citing the inclement weather at the launch base. Ariane 5 VA221 is to place in orbit GSAT-16 which is designed to augment the national space capacity in communication services, along with DIRECTV-14, built by SSL (Space Systems/Loral) for operator DIRECTV to provide direct-to-home television broadcasts across the US. "GSAT-16 launch rescheduled on early morning of December 6, 2014 at 02:09 hrs (IST) is postponed due to inclement weather conditions at French Guiana," Isro said on its website. In this paper we have taken Failure due to inclement weather or Failure due to the unfavorable weather conditions (high altitude winds). When the main unit fails due to Failure due to the unfavorable weather conditions (high altitude winds)then cold standby system becomes operative. Failure due to the unfavorable weather conditions (high altitude winds). cannot occur simultaneously in both the units and after failure the unit undergoes very costly repair facility immediately. Applying the regenerative point technique with renewal process theory the various reliability parameters MTSF, Availability, Busy period, Benefit-Function analysis have been evaluated. Keywords: Cold Standby, Failure due to inclement weather or Failure due to the unfavorable weather conditions (high altitude winds), first come first serve, MTSF, Availability, Busy period, Benefit -Function.
