RELIABILITY AND COST ANALYSIS OF A SYSTEM WITH INSPECTION ON FAILURE AND TWO OPINIONS FOR DIAGNOSIS.

: The present paper investigates a reliability model for a system wherein an inspection is carried out on failure to find out as to which part needs to be repaired/replaced. However, there are chances of wrong diagnosis and hence the second opinion is taken. If the second opinion is in consonance with the first opinion, the necessary part/component of the system is repaired/replaced. However, if the two opinions are contradictory, the system is undertaken by an expert for inspection and repair. The possibility of improper diagnosis cannot be ruled out even if the two opinions are in consonance and the same is revealed some time after putting the system under observation during its operation and then also the system goes under repair of the expert repairman. System is analyzed by making use of regenerative point technique. Various measures of system effectiveness have been attained. Profit of the system is evaluated. Numerical examples are given to validate the derived indices. [ABSTRACT FROM AUTHOR]
