PT Madubaru Madukismo is a company engaged in the manufacture of granulated sugar. The problem faced by that has not reached set production target. It known target 30,000 quintals per month. So for measuring productivity using objective matrix (OMAX) and fault tree analysis (FTA) methods where partial measurement system developed to monitor each part with criteria accordance existence part, met...

The 4-leg inverter can adjust the load current or output voltage even under unbalanced conditions, but it is known that additional switch arm to 3-leg increase overall cost and failure rate. This paper aims analyze rate mean time between failures (MTBF) of inverters using part count analysis (PCA) fault-tree (FTA), compare price inverters. FTA rate, including type, number connection status circ...

Kebakaran adalah salah satu masalah yang tidak terduga. Kerugian ditimbulkan hanya dirasakan oleh pemilik kantin, melainkan seluruh aktivitas di sekitar kantin. Tujuan dari penelitian ini untuk menghindari terjadinya kecelakaan kerja mengakibatkan kebakaran pada kantin instansi X. Pada proses identifikasi dan survey langsung dilakukan lapangan, kemudian dilanjutkan dengan penerapan bantuan meng...

Quantitative risk analysis (QRA) is a systematic approach for evaluating likelihood, consequences, and risk of adverse events. QRA based on event (ETA) and fault tree analyses (FTA) employs two basic assumptions. The first assumption is related to likelihood values of input events, and the second assumption is regarding interdependence among the events (for ETA) or basic events (for FTA). Tradi...

Pandora is a recently proposed technique that extends classical Fault Tree Analysis to incorporate the effects of the temporal ordering of failure events. In this paper, we extend the conceptual foundation of Pandora with a new Priority-OR (POR) gate and we introduce the concept of a Temporal Truth Table as a mechanism that can be used to prove equivalence of expressions in Pandora logic. We al...

In embedded systems development safety and reliability are important quality characteristics. Fault tree analysis is often used to determine these characteristics. Generalized fault trees improve the readability and thus prevent the insertion of bugs, e.g., during manual modification. Fault tree analyses are usually performed manually. Taking into account the high complexity of large, technical...

Train safety monitoring and fault diagnosis are critically important because of the disastrous results caused by train collisions and derailments. Train safety protection sensors network is capable of autonomously monitoring the working condition and actively control faults. A number of strategically placed sensors in the vehicles form a network that can monitor various vital parameters and pro...

In the last 30 years various mathematical models have been used to identify the effect of component failures on the performance of a system. The most frequently used technique for system reliability assessment is Fault Tree Analysis (FTA) and a large proportion of its popularity can be attributed to the fact that it provides a very good documentation of the way that the system failure logic was...

Fault tree analysis (FTA) is one of the most frequently applied safety analysis techniques when developing safety-critical industrial systems such as software-based emergency shutdown systems of nuclear power plants and has been used for safety analysis of software requirements in the nuclear industry. However, the conventional method for safety analysis of software requirements has several pro...

Grid computing environment due to its scale and heterogeneous nature is more vulnerable to faults. To store and analyze fault and workload information, FTA Fault Trace Archive and GWA Grid Workload Archive are used. Previously researchers have analyzed FTA and GWA as separate research problems but in this research paper we have proposed a method for conducting a combined analysis of FTA and GWA...
