A New Method for Reliability Calculation of the Active Systems with Time-Dependent Failure Rates based on Weibull Distribution

pedram Pourkarim guilani; Mani Sharifi; parham azimi; maghsoud Amiri

Volume 19, Issue 61 , August 2021, , Pages 95-124


  Due to the high sensitivity in applying of electronic and mechanical equipment, creating any conditions to increase the reliability of a system is always one of the important issues for system designers. Hence, making academic models much closer to the real word applications is very attractive. In the ...  Read More

Availability Maximization of Redundancy Allocation Problem (RAP) of Series-Parallel System by Considering Failure Rates and Non-Exponential Repair

SEYYED ALI Mirnezhad; Parham Azimi; Ahmad Yousefi Hanoomarvar

Volume 18, Issue 59 , January 2021, , Pages 151-180


  In the present study, the redundancy allocation problem (RAP) of series-parallel system has been investigated to maximize the system's availability. To achieve the research objective, budget, weight and volume constraints, and the maximum and minimum number of elements assigned to each subsystem have ...  Read More

Providing a model to optimize preventive maintenance schedules for multi-component systems using GA

Arman Sajedinejad; Meysam Lotfi

Volume 17, Issue 55 , January 2020, , Pages 137-160


  In this paper, a non-periodic preventive maintenance scheduling optimization model for multi-component systems is provided based on the maximum availability of system components. In addition to providing the required level of system reliability and satisfy other system constraints (maintenance activities ...  Read More
