Fuzzy Fault Tree Analysis

In reliability field, the probabilities of basic events are often treated as exact values in conventional fault tree analysis. However, for many practical systems, because the concept of events may be ambiguous, the factors affecting the occurrence of events are complex and changeable, so it is difficult to obtain accurate values of the occurrence probability of events. Fuzzy sets can well deal with these situations. Thus this paper will develop a novel fault tree analysis method in the assumption of the values of probability of basic events expressed with triangular intuitionistic fuzzy numbers. First, a new ranking function of triangular intuitionistic numbers is established, which can reflect the behavior factors of the decision maker. Then a novel fault tree analysis method is put forward on the basis of operational laws and the proposed ranking function of triangular intuitionistic numbers. Finally, an example of weapon system “automatic gun” is employed to show that the proposed fault tree analysis method is feasible and effective.

SAŽETAK: Prirodni plin danas se smatra najvećim izvorom energije potrebne stambenim područjima i industriji. Pogled na tehnologije kojima se Iran koristi otkriva da su plinovodi najbolji i najsigurniji način za distribuciju prirodnog plina u zemlji. Ovaj izvor energije, koji se ponekad naziva čistim gorivom, ima stratešku ulogu u opskrbi potrebne energije. S druge strane, opskrba gorivom mora biti stalna, ali i sigurna. Stoga se zaključuje da su potrebne odgovarajuće mjere za upravljanje rizicima od curenja, požara i eksplozija na ovakvim postrojenjima. Za postizanje toga cilja najpotrebnije je ustanoviti uzroke nesreća i ispitati pouzdanost. Nadalje, neizbježno se mora procijeniti vjerojatnost događanja nesreće na cjevovodima. Jedan od ključnih koraka u procesu vrednovanja rizika jest procjena vjerojatnosti mogućih nesreća. Članak se koristi FTA (fault tree analysis) metodologijom za proučavanje načina procjene vjerojatnosti nesreća na cjevovodima za prirodni plin. Nadalje, ponuđena je i nova metoda temeljena na pridruživanju težina stablu kvarova, a ‘what-if’ (što-ako) scenarij služi za utvrđivanje opasnosti pri transportu prirodnog plina od njegova glavnog izvora. Na osnovi rezultata studije predlaže se da se vjerojatnost događanja nesreća na cjevovodima za prirodni plin kontrolira tehničkim i sustavnim pristupom kojim se utvrđuju i kontroliraju uzroci tih nesreća.

Dual Fuel Diesel Engine (Mesin Bahan Bakar Ganda) merupakan mesin denganpemanfaatan dua bahan bakar dalam proses pembakarannya untuk memperoleh tenaga kerjapada mesin. Jenis bahan bakar yang digunakan meliputi bahan bakar Methane Gas (CH4)dan MGO (Marine Gas Oil). Methane (CH4) dihasilkan dari Vapour Cargo Tank LNG(Liquified Natural Gas). Tujuan dari penelitian ini adalah untuk mengetahui apa sajapenyebab tingginya suhu gas buang terhadap kinerja Dual Fuel Diesel Engine di MV.Tangguh Palung dengan menggunakan metode analisis data Fault Tree Analysis. Darianalisis data penelitian di hasilkan beberapa rumusan masalah yaitu, faktor-faktor yangdapat menyebabkan tingginya suhu gas buang pada Dual Fuel Diesel Engine adalahkurangnya suplai udara pembakaran dalam ruang pembakaran mesin, komposisipembakaran yang tidak sesuai antara bahan bakar minyak dan gas, serta suhu Engine Roomyang terlalu panas. Dampak yang di timbulkan adalah kerusakan pada komponen-komponenpermesinan dan penurunan kinerja dari Dual Fuel Diesel Engine. Untuk mengatasipenurunan kerja pada Dual Fuel Diesel Engine adalah dengan melaksanakan perawatan danperbaikan pada setiap komponen permesinan yang mengalami masalah dan kerusakan sesuaidengan Running Hours dan Instruction Manual Book.
