In this paper we have characterized the epimorphisms in the full subcategory of Hausdorff fuzzy topological spaces (introduced by Srivastava et al.[10]) of the category FTS of fuzzy topological spaces and fuzzy continuous functions using the Salbanytype closure operator.

Heterarchical FMS control architectures localize decisional capabilities in each entity, resulting in highly reactive, low complexity control architectures. Unfortunately, these architectures present myopic behavior since decisional entities have limited visibility of other decisional entities’ behavior and the alignment of an entity’s decision with the system’s global objective. In this paper,...

Transport policy research seeks to predict and substantially reduce the future transport-related greenhouse gas emissions and fuel consumption to prevent negative climate change impacts and protect the environment. However, making such predictions is made difficult due to the uncertainties associated with the anticipated developments of the technology and fuel situation in road transportation, ...

Over the last two decades, virtually every facet of fleet management and operation has changed in one way or another. Among the most significant catalysts for change in the fleet industry have been legislation, economic globalization, and technological development. Whereas legislation and globalization can lay claim to significant gains in engine efficiency, reductions in vehicle emissions, and...

On 9th March 1916 the Deputy Surgeon General of the Royal Navy, Robert Hill, joined the Iron Duke as Medical Officer and thus became Medical Officer of the Home Fleet. This position reflected the importance of the vessel as Admiral of the Fleet Jellicoe’s Headquarters at sea. The Royal Navy obviously anticipated action for below is an abridged copy of the report rendered by the Fleet Medical Of...

We present a discrete-event simulation model for maintenance operations of a fleet of fighter aircraft in crisis situations, where the fleet operations are affected by a threat of an enemy's actions. The model describes the flight process and basic modes of periodic maintenance and failure repairs. Features that are specific to crisis situations include battle damages of the aircraft, decentral...
