The principal focus of this paper is to study carrier pricing decisions for a new type of vehicle routing problems defined in a competitive and dynamic environment. This paper introduces the Vehicle Routing Problem in a Competitive Environment (VRPCE), as an extension of the Traveling Salesman Problem with Profits (TSPP) to a dynamic competitive auction environment. In the VRPCE, the carrier mu...

This paper proposes a new bilateral control scheme to ensure both transparency and robust stability under unknown constant time delay in stiff environment. Furthermore, this method guaranties suitable performance and robust stability when transition occurs between soft and stiff environments. This framework is composed of an adaptive sliding mode controller and an adaptive impedance controller,...

This study explored the relative competitive ability and performance of first-feeding growth hormone (GH) transgenic and non-transgenic Atlantic salmon Salmo salar fry under low food conditions. Pair-wise dominance trials indicated a strong competitive advantage for residents of a contested foraging territory. Transgenic and non-transgenic individuals, however, were equally likely to be dominan...

Increasing concentrations of CO2 in the atmosphere are likely to affect the ecological dynamics of plant populations and communities worldwide, yet little is known about potential evolutionary consequences of high CO2. We employed a quantitative genetic framework to examine how the expression of genetic variation and covariation in fitnessrelated traits, and thus, the evolutionary potential of ...

the future economy would be a network-centric economy. networks yield more meaning to the concept of perfect competition market. the successful presence in the network-centric economy requires identification and application of new technologies. in today’s competitive business environment, everything is continuously changing and the only thing remains intact is change. environment pressures forc...
