A different intermodal transportation model based on cost analysis considering technical, economical, and operational parameters is presented. The model consists of such intermodal modes as sea-road, sea-railway, road-railway, and multimode of sea-road-railway. A case study of cargo transportation has been carried out by using the suggested model. Then, the single road transportation mode has b...

In this paper I argue—against van Fraassen’s constructive empiricism—that the practice of saving phenomena is much broader than usually thought, and includes unobservable phenomena as well as observable ones. My argument turns on the distinction between data and phenomena: I discuss how unobservable phenomena manifest themselves in data models and how theoretical models able to save them are ch...

This work considers the seats on airplanes, trains, buses and cars as non-regular fixed lifetime inventories developed a revenue generating function for each trip embarked upon by any of these means transportation. Numerical examples use was also discussed.

Although considerable research has investigated perspective making and perspective taking processes in existing communities of practice, little research has explored how these processes are manifest in fluid online collectives. Fluid collectives do not share common emotional bonds, shared languages, mental models, or clearly defined boundaries that are common in communities of practices and tha...

The solid transportation problem is an important extension of the traditional transportation problem. Solid transportation problem with uncertain variables as its parameters is called uncertain solid transportation problem. In this paper, the expected-constrained programming for an uncertain solid transportation problem is given based on uncertainty theory. According to inverse uncertainty dist...
