Profit and availability optimization of two modules with maintenance
This paper discusses the Profit and Availability Optimization of Two Modules with Maintenance, in which modules can work in complete and reduced capability. In this two module model both the modules can work in reduced state which means the software is having partial features and need corrective maintenance to reach the full capacity working state. This model also contains the perfective maintenance. Proposed model deals with two type of states of failures: Partially failure and fully failure. This model consists of module ‘A’ and module ‘B’. The module ‘A’ or ‘B’ can fail partially and hence can be in upstate. The module failure can be due to S/W or H/W. The software system can work with reduced capacity in a partially failed state. There is a single repairman available for both type of failure. Up-dation are faultless i.e. during repair the repairman never does any damage to the modules and a repaired module is working like a new module. The service time are exponential and is different for both type of failures(S/W and H/W). The software system is considered for steady-state. To measure the performance of the software system Regenerative Point Graphical Technique (RPGT) is used to study system parameters.
