In transportation planning there can be long lead times to adapt capacity. This paper addresses two questions. First, in a one mode world (say rail or road), what is the optimal capacity choice when faced with uncertain demand, long lead times and congestion. Using a simple analytical model it is shown that when demand is inelastic, it is socially optimal to invest more than if only the expecte...
This paper presents a new model of two-echelon periodic supply vessel planning problem with time windows mix of facility location (PSVPTWMFL-2E) in an offshore oil and gas industry. The new mixed-integer nonlinear programming (MINLP) modelconsists ofa fleet composition problem and a location-routing problem (LRP). The aim of the model is to determine the size and type of large vessels in the fi...
Mixed convection fluid flow and heat transfer of water-Al2O3 nanofluid inside a lid-driven square cavity has been examined numerically in order to find the optimal distribution of discrete heat sources on the wall of a cavity. The effects of different heat source length, Richardson number and Grashof number on optimal heat source location has been investigated. Moreover, the average Nusselt num...
The Second-Best Toll Pricing (SBTP) problem aims to determine an optimal toll scheme for a given set of links in a transportation network so that traffic can be distributed more efficiently from the system point of view. SBTP can be further categorized as static SBTP or dynamic SBTP (DSBTP), depending on whether traffic dynamics are considered or not. In this paper, we focus on the static SBTP ...
This paper considers the second-best problem where not all links of a congested transportation network can be tolled. The paper builds on earlier work, in which the secondbest tax rule for this problem was derived for general static networks, so that the solution presented is valid for any graph of the network, and for any set of tolling points available on that network. An algorithm is present...
