SIVILAŞTIRILMIŞ DOĞAL GAZ TAŞIMA YOLLARININ AĞ TABANLI OPTİMİZASYONU

Öz

Son yıllarda, uygun fiyatlı ve verimli bir temiz enerji kaynağı hızlı bir gelişme dönemine girmiştir: sıvılaştırılmış doğal gaz (LNG) yanma sırasında petrol veya kömürden daha az karbondioksit yayar. Aslında, LNG sadece enerji üretimi, kentsel gaz ve sanayi için yaygın olarak kullanılmamıştır. Ayrıca, LNG kamyonlarının hızla artmasında başı çeken bir otomotiv yakıtı olarak kademeli biçimde benimsenmiştir. Bununla birlikte, LNG kamyon taşımacılığı ile ilgili güvenlik sorunları giderek daha belirgin hale gelmiştir. LNG yanıcı olduğundan ve patlama riski içerdiğinden, bir kaza meydana geldiğinde, sızıntı nedeniyle yangına ve patlamalara neden olmaya eğilimlidir. Daha önceki çalışmalar, tehlikeli madde taşıma yolları için en kısa yol sorununu basitleştirmiştir. Ancak, bu yöntem, kazalardan sonra kurtarma yeteneklerinin de göz önünde bulundurulması gereken gerçek durumları kolayca yansıtmaz. Bu nedenle, LNG taşıma yollarının optimize edilmesi önemlidir. Bu optimizasyon, düşük kaza riski ile ulaşım verimliliğinin sağlanması, kurtarma tesislerinin güvenliğinin sağlanması ve çevre üzerinde çok az etkiye sahip olması üzerine yoğundur.

NETWORK-BASED OPTIMIZATION OF LIQUEFIED NATURAL GAS TRANSPORTATION ROUTES

Öz

In recent years, one affordable and efficient clean energy resource has entered a period of rapid development: liquefied natural gas (LNG) emits less carbon dioxide during combustion than oil or coal. In fact, LNG has not only been used widely for power generation, urban gas, and industry. It has also been adopted gradually as an automotive fuel, leading to the rapid growth of LNG trucks. However, safety issues related to LNG truck transportation have become increasingly prominent. Because LNG is flammable and entails risk of explosion, once an accident occurs, it is prone to cause fire and explosions because of leakage. Earlier studies simplified the shortest path problem for dangerous goods transportation routes. However, this method does not readily reflect actual situations in which rescue capabilities after accidents must also be considered. Therefore, optimizing LNG transportation routes is important. That optimization is premised on ensuring transportation efficiency with low accident risk, securing rescue facilities, and with little effect on the environment.
