A Bi-Objective Optimal Task Scheduling Model for Two-Machine Robotic-Cell Subject to Probable Machine Failures

Bahareh Vaisi; Hiwa Farughi; Sadigh Raissi; Heibatolah Sadeghi

Volume 10, Issue 1 , March 2023, , Pages 141-154

  In this study, we model a stochastic scheduling problem for a robotic cell with two unreliable machines susceptible to breakdowns and subject to the probability of machine failure and machine repair. A single gripper robot facilitates the loading/unloading of parts and cell-internal movement. Since it ...  Read More

Residual Lifetime Prediction for Multi-State System Using Control Charts to Monitor Affecting Noise Factor on Deterioration Process

Neda Gol-Ahmadi; Sadigh Raissi

Volume 5, Issue 1 , June 2018, , Pages 27-38

  In this research, multi-state complex systems are analyzed in order to measure reliability and predict residual of systems’ lifetime under the effect of an out of control noise factor. Hence, the analytic method helps us to estimate multi-state system reliability, and then means residual lifetime ...  Read More
