In this maintenance policy, we will fix the operation period and carry out the system maintenance in a short period before the next operation cycle. During this defined time,  some  maintenance  actions,  for  example:  the  replacement  of  an  identical  item,  the  rehabilitation or doing nothing actions will be considered and realized for each component. Due  to  the  fixed  maintenance  period  is  usually  not  enough  for  maintenance  of  all  components in the system, only some components are selected for maintenance during that period in order to maximize availability. A  mathematical  model  is  proposed  to  help  maximize  system  the  availability  according  to  the  time  and  budget  constraints  of  preventive  maintenance.  This  model  is  executed  for  a  serial-parallel  system  and  then  applied  for  the  maintenance  problem  at  a  gas  processing  plant in Vietnam. @Risk Optimizer program is used for solution purpose. From numerical and sensitivity analysis results, some recommendations are also derived.   aThesis (M.Eng.) - Asian Institute of Technology, 2010 0aPlant maintenancezVietnam 0aMaintenancezVietnam1 aHuynh, Trung Luong,eChairperson0 aVoratas Kachitvichyanukul,eExamination Committee2 aPetroVietnam, eScholarship donor        2 aAsian Institute of Technology.tThesis ;vno.
