The optimization of maintenance time and total site crew for Base Transceiver Station (BTS) maintenance using Reliability Centered Maintenance (RCM) and Life Cycle Cost (LCC)

摘要

In a telecommunications network architecture, BTS holds a very important role. In the event that causes disruption of BTS and BTS to be down, it will result in loss of potential revenue and lead to loss of consumer loyalty in the company. Hence the need for an effective method of treatment BTS and BTS efficient so that availability can be maintained properly. The method used in the treatment of BTS in this study is the RCM method (Reliability Centered Maintenance) to determine treatment priorities of existing equipment in the BTS based on vital functions and data destruction in order to obtain its value MTTF and MTTR, as well as LCC method (Life Cycle Cost) to determine the optimal number of sites crew for treatment BTS. By using the RCM method, the results of the determination of the critical components based on damage data, are obtained two set of equipment as critical components. They are generator and transmission module BCKM. Calculation and data processing of field data acquisition and secondary data the previous year, the value of the MTTF BCKM module is 1109.635 hours and MTTR BCKM 6,095 hours, while the value of the generator is 1647,373 hours MTTF and MTTR generator is 3.6 hours. While the number of site crew required in the BTS treatment based on the results of calculation and data processing with the LCC method, obtained the most optimal amount based on the cost is 4 site crews.
