Evaluating the Efficiency of Iranian Regional Railways
Railway transportation plays an important role in the economic development of Iran. National Iranian Railways includes fifteen regional railways which operate independently, but under the supervision of National Iranian Railways Company. Evaluating the efficiency of regional railways is an important issue in Iran and is one of the bases for budget and resource allocation for further developmen...
متن کاملTechnical Note: The South Eastern and Chatham Railways Managing Committee
In 1898, two railways serving the south-east of England agreed to be managed by a joint committee. This paper finds clear statistical evidence of the negative impact this had on total economic costs, including opportunity costs of capital, as well as working expenditure. Thus, additional support was provided for the then British railway policy already strongly suspicious of railway mergers on c...
متن کاملManaging Energy Efficiency in Manufacturing Processes - Implementing Energy Performance in Production Information Technology Systems
Climate change and unsecured energy supply are topics that become increasingly important in today’s society. Although renewable energy technologies may be a long-term solution, more efficient energy use potentially makes a high and economic contribution to the given challenges in the short term. New CO2 regulations, rising energy prices and environmentally aware customers make energy efficient ...
متن کاملExploiting MAS-Based Simulation to Improve the Indian Railways' Efficiency
Despite being one of the world’s largest railways networks, with a daily transportation of over 25 million passengers and 2.8 million tons of freight, the Indian Railways perform their signaling, traffic management and trains scheduling activities in a completely manual way. The lack of automation causes not only significant delays, but also frequent collisions where passengers die or remain se...
متن کاملEnergy Efficiency in Iran Provinces: DEA Approach
The main aim of this paper is to evaluate the energy efficiency in 30 provinces of Iran by applying the different methods of DEA and Anderson and Peterson during the period of 2009-2013. Also, since classical analysis models do not differentiate efficient cases, the AP method (Anderson-Peterson) was used to rank efficient units for evaluating efficiency correctly. So that combination of input v...
