Generating of multi-criteria alternatives for decision-making in electric light rail control

The purpose of this paper is to study and evaluate genetic algorithms and scheduling theory about the methods of controlling public electric transport. Scheduling theory can be defined as criteria of time constraints for target functions of the optimal electric transport control task and for electrical process diagnostics task. Mathematical models and procedures are developed for the control of electrical processes and the optimization of railway traffic control, using scheduling theory and multi-criteria of decision making. Functional dependencies between electrical processes and dynamics of electric transport flow states are investigated in the research. Genetic algorithms are investigated for getting dynamic multi-criteria optimization of processes in real time mode. Efficiency of proposed methods about procedures for optimal electric transport flow control is analyzed and. Safety is considered as an inherent component of the total transport system, which embraces infrastructures, goods and containers, transport users and operators, vehicles and vessels, measures at policy and legislative levels includes decision support and validation tools. Integrated safety and security systems for surface transport systems includes advanced modeling, simulation and engineering tools, aiming at the improvement of safety and security performance of transport systems. Development will include methodologies and designing environments for risk based design and approval, roll-over test development and pre-normative research towards regulations based on virtual testing methods as well as mechatronic systems for dynamic stability, reliable and effective braking systems for vehicles. The paper is based on authors＇ previous scientific work which researches the intelligent device systems and their applications in transport systems. Intelligent devices are controllers, which have interface to work in global network and wireless networks, and are programmed to use methods of the artificial intelligence. Intelligent devices have possibilities to negotiate with each other and to coordinate their work to get better decision. The results of experiments show the possibility of the developed systems to prevent accidents and to avoid different problems by intelligent diagnostic and coordination devices.

Howard Hopson’s billion dollar fraud: The rise and fall of associated gas & electric company, 1921–1940

Abstract

This is a case study of financial fraud. The Associated Gas & Electric Company (AG&E), controlled by Howard C. Hopson, was one of the largest utility holding companies of the ‘Roaring 20s’. Hopson’s AG&E rose spectacularly in the market boom and fell hard following the 1929 crash. Hopson tried unsuccessfully to save the company, while simultaneously enriching himself, using financial transactions that ultimately were determined to be illegal. The major policy reaction to the financial manipulations of the period, for which Hopson became a public symbol, was passage of the Public Utility Holding Company Act, which mandated the ‘death’ of most electric utility holding companies.
