Airline delay costs are incurred both on the day of operations (tactical cost) and at the planning stage (strategic cost). The latter may take the form of buffer in schedules. Strategic and tactical costs are not independent. Passenger costs of delay to the airline, crew, fuel, maintenance and fleet costs are quantified. Cost trade-offs are presented as a 3D plot assessing the ‘break-even’ poin...

organizations particularly in project structure pay specialattention to the efficient management and make a lot of efforts to achievethis goal by reducing delay in projects. gas transmission zones are amongthose kinds of organizations whose main activities are considered to be inproject structure. thus the significance of project management and thepathology of delay that imposes exorbitant cost...

A project is any endeavor involving planned action, for example, developing a new product or constructing a dam. [CE1] Major factors for a project to be successful are applying performance measurement and feedback tool. One such well-known performance measurement tool to control the project execution is earned value management (EVM). EVM uses the fundamental principle that trends in the past ca...

Objective: The aim of this paper is to propose a new approach to assess the aggregated impact of risks on the completion cost of a construction project. Such an aggregated impact includes the main impacts of risks as well as the impacts of interactions caused by dependencies among them. Methods: In this study, Monte Carlo simulation and Bayesian Networks methods are combined to present a frame...

Delay-tolerant networking (DTN) is a term invented to describe and encompass all types of long-delay, disconnected, disrupted or intermittently-connected networks, where mobility and outages or scheduled contacts may be experienced. ‘DTN’ is also used to refer to the Bundle Protocol, which has been proposed as the one unifying solution for disparate DTN networking scenarios, after originally be...
