Abstract: This paper presents a mathematical model for a multi-state complex repairable manufacturing system with four types of failures such as common cause, partial, human and catastrophic incorporating waiting time to repair. As regards to repairing of the system, it has to be wait for repair due to unavailability of repair facility after common cause failure. The system may also fail due to...

In this paper an analytical approach for the reliability evaluation of complex manufacturing system is presented, where a manufacturing system is in operative state only if its production capacity requirements are satisfied. We considered a manufacturing system with three types of failures namely type I, type II and type III failures. The proposed system works in four modes: normal, degraded, d...

The design of a suitable interconnection network for inter-processor communication is one of the key issues of the system performance. The reliability of these networks and their ability to continue operating despite failures are major concerns in determining the overall system performance. In this paper a new irregular network IABN (Irregular Augmented Baseline) has been proposed. IABN is desi...

Availability and reliability of a manufacturing system are the most common indicators in the reliability engineering area to assess the quality and on-time deliveries of the products they produce. The purpose of this paper is to analyze the availability, reliability. failure metrics such as MTBF and MTTF, and also steady-state availability of a cooking oilproduction line using a Markov approach...

Reliability models based on Markov chain (Except in queuing systems) have extensive applications in electrical and electronic devices. Here, we consider a k-out-of-n:G system with n parallel and identical elements with increasing failure rates (failure rates are Weibull distributed) and non repairable elements. The failure rate of remaining elements increases when some elements fail. The system...

Reliability is used to estimate the conditions of systems or components in future based on previous conditions. The objects this research are EC 155B1 aircrafts owned by Indonesia Air Transport & Infrastrucure (IAT), and method for analysis markov analysis. Markov widely as an analyzing technique states system that has limited information (memoryless). From research, ATA chapter 62 Main Rot...

The paper is to present a simulation method to search for an optimal (z, Z) (z < Z) values for the (z, Z) production control policy so that the expected inventory cost rate (i.e. expected total cost due to both inventory holding and backlog per unit time) is minimal for a single machine system with buffer. The system is subject to operationdependent failure only and alternates between normal an...

This paper analyses the reliability of a cold standby system consisting of two repairable units, a switch and a repairman. At any time, one of the two units is operating while the other is on cold standby. The repairman may not always at the job site, or take vacation. We assume that shocks can attack the operating unit. The arrival times of the shocks follow a homogeneous Poisson process and t...
