SISTEM ANTRIAN MODEL GEO/G/1 DENGAN VACATION

Queue  processes  are  stochastic processes  which  involve  the  arrival pro- cess and  the  service  process.  In a queue,  there  is a condition of servers  that become unavailable for a period  of time  called  vacation. The  purpose  of this  research  is to analyze  the  derivation Geo/G/1 queue  systems  model  with  vacation and  its applica- tion.  Furthermore, based  on simulation on vacation model,  with  different values  of traffic  intensity and  vacation parameter, we concluded  that the bigger  traffic  inten- sity and  vacation parameter values,  then  the  mean  of total number of costumers in a system  and  the  mean  of waiting  time  in the  queue  that is caused  by vacation will be decreased.
