The safe movement of hazardous materials is receiving increased attention due to growing environmental awareness of the potential health affects of a release causing incident. A novel approach developed in this paper through a game theory interpretation provides a risk-averse solution to the hazardous materials transportation problem. The dispatcher minimizes the expected maximum disutility subject to worst possible set of link failure probabilities, assuming that one link in the network fails. The expected cost at the Nash equilibrium is a useful measure to evaluate the routing strategies for the safe movement of hazardous materials.

YAKLASIMSAL HİBRİD METODLA GÜVENLİ TEHLİKELİ MADDE TASIMACILIGI: TABU ARASTIRMA VE OYUN TEORİSİ UYGULAMASI

Öz

Tehlikeli madde tasımacılıgında olusacak herhangi bir kazanın gerek insan saglıgına gerekse de çevreye olacak olan etkilerine karsı olusan duyarlılıgın artmasıyla, bu çesit tasımacılıgın güvenligine yönelik kaygılar artmıstır. Bu makalede tehlikeli madde tasımacılıgı oyun teorisi çerçevesinde en az riski içerecek çözüm metoduyla modellenmistir. Tasımacı organizasyon sebekedeki linklerden maksimum olumsuz etkiyi olusturacak olanın üzerinde bir kazanın oldugu varsayımıyla beklenen maksimum maliyeti minimize etmeye çalısarak Nash dengesi çerçevesinde en güvenli tasıma güzergâhını belirlemektedir.
