An analysis was conducted to examine the market visibility of small aircraft as a transportation mode in competition with automobile and scheduled commercial air travel by estimating the pool of users that would potentially switch on-demand air travel due to cost/time saving. These new aircraft greatly increase the practicality of regional aircraft as a transportation mode that can avoid the co...

In this paper, new methodologies are proposed for solving unbalanced fuzzy transportation problems without converting into a balanced one. The advantages of these methodologies are to get an optimal solution. In the proposed method, transportation costs, demand and supply are represented by triangular fuzzy numbers. To illustrate the proposed method, numerical examples are solved and the obtain...

In this paper, a new method is proposed for solving a special type of fuzzy transportation problem by assuming that a decision maker is uncertain about the precise values of transportation cost only but there is no uncertainty about the supply and demand of the product. In the proposed method transportation costs are represented by generalized trapezoidal fuzzy numbers. To illustrate the propos...

Abstract This paper proposes an optimization scheme of the transportation assignment for the oil product secondary distribution. Firstly, for the multi-variety oil product a cost model of the secondary distribution system for the oil product is established. Then a transportation assignment scheme is designed with the table-manipulation method. Based on the proposed transportation assignment sch...

We compare two methods of measuring melodic similarity for symbolically represented polyphonic music. Both exploit advantages of transportation distances such as continuity and partial matching in the pitch dimension. By segmenting queries and database documents, one of them also offers partial matching in the time dimension. This method can find short queries in long database documents and is ...

A new method using the principle of zero point method [10] is proposed for finding an optimal solution of solid transportation problems. The proposed method yields an optimal solution of the given solid transportation problem directly . It is very easy to understand and apply which can serve managers by providing the optimal solution to a variety of distribution problems involving three items. ...

In the academic and professional literature on freight transportation, computer-based planning methods have a long time ago been identified as a means to achieve cost reduction through enhanced transportation operations efficiency. More recently, inter-firm collaboration in transportation planning has been investigated as a means to provide further gains in efficiency and, in turn, to achieve a...

One abstract method for the study of network transportation is proposed in this paper. By interpolating the properties of the edges that constitute network into the two leading parameters of the nodes, this method can abstract the configuration of real-life transportation networks without losing the influence of the distance and the capability of the physical facilities, which are essential par...
