This paper examines the importance of tactical and strategic information sharing between supply chain partners. Through a transaction cost economics theoretical lens, we hypothesize that greater tactical and strategic information sharing volumes are associated with greater survival of supply chain relationships. We also hypothesize that a greater ratio of strategic to tactical information shari...

Airline delay costs are incurred both on the day of operations (tactical cost) and at the planning stage (strategic cost). The latter may take the form of buffer in schedules. Strategic and tactical costs are not independent. Passenger costs of delay to the airline, crew, fuel, maintenance and fleet costs are quantified. Cost trade-offs are presented as a 3D plot assessing the ‘break-even’ poin...

The purpose of this paper is to present a multi-level operational C holonic reference architecture that is applicable to Navy maritime headquarters (MHQ) with maritime operations center (MOC) for assessing, planning and executing multiple missions and tasks across a range of military operations. The control architecture consists of three levels: strategic level control (SLC), operational level ...

Possible dimerization patterns and electronic structures in fullerene tubules as the π-conjugated systems are studied with the extended Su-Schrieffer-Heeger model. We assume various lattice geometries, including helical and nonhelical tubules, and tubules with end caps. The model is solved for the half-filling case of π-electrons. (1) When the undimerized systems do not have a gap, the Kekulé s...

In this paper, virtual cell layout (VCL) based dynamic source routing (VB-DSR) technique is introduced for the mobile subsystem of the next generation tactical communications systems. VB-DSR uses dynamic source routing (DSR) protocol over VCL structure, which is a resource management and clustering technique for tactical communications. The application of the third generation personal communica...

It is known that every class-regular symmetric μ,m -net is tactical. Also it is known that all μ,m nets with m 2 or μ 1 are tactical. In the work of Al-Kenani and Mavron 2003 , it is proved that every symmetric net with m 3 is tactical if and only if it is class regular. In this paper, we construct 2, 4 -net and show that it is class regular and therefore tactical. New necessary and sufficient ...
