In this paper, a single-source capacitated multifacility location problem with rectilinear distance under unbalanced transportation constraints is studied. The problem is formulated as a mixed integer linear programming problem of which the objective function is the sum of nonlinear functions. An algorithm under decomposition approach combining with logic based techniques is developed. Using th...

In this paper, we develop the fuzzy fixed charge transportation problem when the costs are the fuzzy numbers. The first step it transform into the classical fuzzy transportation problem. The next, we obtain the best approximation fuzzy on the optimal value of the fuzzy fixed-charge transportation problem. This method obtains a lower and upper bounds both on the fuzzy optimal value of the fuzzy ...

The dial-a-ride problem is a classic challenge in transportation and continues to be relevant across a large spectrum of applications, e.g. door-to-door transportation services, patient transportation, etc. Recently a new variant of the dial-a-ride problem, called ride-sharing, has received attention due to emergence of the use of smartphone-based applications that support location-aware transp...

User location prediction in location-based social networks can predict the density of people flow well terms intelligent transportation, which make corresponding adjustments time to traffic smooth, reduce fuel consumption, greenhouse gas emissions, and help build a green cycle low-carbon transportation system. This paper proposes Markov chain position model based on multidimensional correction ...

Growing public awareness of climate change requires transportation professionals to integrate green concepts into the transportation planning, design, construction, and operation processes. For the past decade, while many studies have been done regarding carbon emission reduction strategies for on-road and off-road operations, very few have dealt with emission reduction issues in highway projec...

discrete facility location,   distribution center,   logistics,   inventory policy,   queueing theory,   markov processes, the distribution center location problem is a crucial question for logistics decision makers. the optimization of these decisions needs careful attention to the fixed facility costs, inventory costs, transportation costs and customer responsiveness. in this paper we study t...

Webster’s Dictionary defines location as (1) position in space, and (2) an area marked off for a specific purpose. Hence, a location problem would involve identifying a specific position or place for a specific function or activity. There are several common types of location problem associated with GIS. The most common involves the measurement of where something exists. Given adequate time, it ...

Hinterland transportation has become increasingly critical for global container supply chain performance. However, the literature on the management of the container supply chain tends to overlook the issues related to hinterland transportation. The problem we consider here is faced by a deep-sea terminal operator who wants to open an inland terminal to facilitate its operations. When developed ...

In this paper, a stochastic programming approach is applied to the airline network revenue management problem. The airline network with the arc capacitated single hub location problem based on complete–star p-hub network is considered. We try to maximize the profit of the transportation company by choosing the best hub locations and network topology, applying revenue management techniques to al...
