In this paper, a novel rating based fuzzy analytic network process (F-ANP) model is proposed for the evaluation of ship maneuverability and the improvement of maneuverability standards. By incorporating the F-ANP technique into the American Bureau of Shipping (ABS) maneuverability standards, the proposed model is able to solve the problem of mutual dependencies of the maneuvering factors inhere...

The chemical evolution of the exhaust plumes of ocean-going ships in the cloud-free marine boundary layer is examined with a box model. Dilution of the ship plume via entrainment of background air was treated as in studies of aircraft emissions and was found to be a very important process that significantly alters model results. We estimated the chemical lifetime (defined as the time when diffe...

Maritime safety is an ongoing process in shipping that constantly being improved by the modernization of equipment and constant improvements operators’ procedures training. However, human error remains a significant factor maritime accidents, as it contributes to 75% incidents. Addressing this problem, current paper shows proof principal for on-board fire monitoring extinguishing software agent...

Maritime wireless communication is different from terrestrial wireless communication, due to difference of environments. In this paper focuses to simulate on IEEE 802.16j for ship to ship maritime communication under various sea states. We describe BER level according to sea states under Rician fading channel model. BER patterns are designed using MATLAB.

Manoeuvring ship during berthing has always required vast experience, skill and knowledge to provide desired necessary actions. Presence of environmental disturbances as well as decreased manoeuvrability in low speed often makes the whole procedure so sophisticated that even slight mistake may results catastrophic disaster. By knowing the fact that Artificial Neural Network (ANN) has the abilit...

Helicopters operations on board ships require special procedures introducing additional limitations known as ship helicopter operational limitations (SHOLs) which are a priority for all navies. This paper presents the main results obtained from the experimental investigation of a simple frigate shape (SFS) which is a typical case of study in experimental and computational aerodynamics. The resu...

The traditional Economic Order Quantity (EOQ) model ignores the physical limitations of distribution practices. Very often distribution centers (DC) have to deliver merchandize in manufacturer-specified packages, which can impose restrictions on the application of the economic order quantity. These manufacturer-specified packages, or ship-packs, include cases (e.g., cartons containing 24 or 48 ...
