One of the architectural concerns in the present design of the Muon Trigger Track Finder (MTTF) is the large number of inputs to the Track Assembler (TA). In the TA block, input track segment pairs from many Extrapolation Units (EU) are associated into tracks. The relative contribution of these inputs to the assembled tracks is studied with simulated track patterns for low and high pt muons ove...

An advanced safety architecture is the 2 out of 4-system (2oo4). In order to trigger the safety function at least two of the four channels must work correctly. It is said: “A 2oo4-system is 2-failure safe”. In order to classify the quality of a system we calculate different parameters. In the report equations are indicated for PFD for normal and common-cause-failures. Also the Markov-model for ...

Abstract This paper deals with the availability analysis of a complex system that consists of two subsystems namely subsystem 1 and subsystem 2.Subsystem 1 is working under k-out of –n good policy and subsystem 2 has two identical units in parallel configuration. Controller for proper functioning controls the subsystems 1. All failure rates are constant and follow exponential distribution but r...

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...

Soft errors are a growing concern for processor reliability. Recent work has motivated architecture level studies of soft errors since the architecture level can mask many raw errors and architectural solutions can exploit workload knowledge. My dissertation focuses on the modeling and analysis of soft error issues at the architecture level. We start with the widely used method for estimating t...

Sistem perawatan yang dilakukan selama ini adalah bersifat breakdown maintenance yaitu pemeliharaan setelah mesin mengalami kerusakan. belum memberikan data akurat kapan suatu atau komponen kerusakan, sehingga strategi tepat untuk menjaga tetap beroperasi menentukan interval waktu optimal.Hasil analisis dengan menggunakan metode Failure Mode Effect Analysis (FMEA) maka didapat kritis pada Mesin...

Based on damage data owned by PT XYZ, the compressor engine that has a history of high is D32 CP8 Compressor Engine. Critical components CP 8 are determined using risk matrix. The critical selected from Engine Screw Motor, Refrigerant Air Cooler, and Cylinder Bearing Oil Cooler. This study uses Reliability Centered Spares (RCS), Min-Max Stock, Reorder Point (ROP) methods. collection processing ...

PT. XYZ is engaged in the production of snacks. This company makes products from raw materials to finished products. In packaging section using a machine called CingFong, problem that often occurs there buildup due waiting for machines have not maintenance so it can reduce productivity this factory. Overall method used Preventive Maintenance by looking Mean Time To Failure (MTTF) identify criti...

Here, a new buck–boost converter with reliability analysis is proposed. The has utilized voltage multiplier cell at the input side to boost output voltage. It continuous current wide range of duty cycle operations. achieves unity gain 26.8% and can also operate in discontinuous conduction modes buck modes. detailed proposed using improved Markov modelling presented by considering both open circ...
