The mixed vehicle routing problem with backhauls is investigated using ant system heuristic. This distribution problem seems to suffer from a lack of published work even though it has immense practical applicability especially within logistic systems. Some enhancements to the basic ant system...

The paper is aimed at working out the mathematical models and methods to solve the problems of operation of developing heat supply systems in a competitive market environment. The formation of new principles of functioning in this field is conditioned by the market mechanisms emerging due to the...

This paper presents the key findings of a study conducted in Greek hotels. Energy audits were carried out in 43 cases across Greece. The different technical characteristics of each building have a different effect in the total final energy consumption. The findings of this research showed the...

An economic estimation of a network of distributed energy resources (DERs) forming a power delivery system in an Indian scenario has been made. The mathematical analysis is based on the application of real valued cultural algorithm (RVCA). The RVCA-evaluated total annual cost for power delivery...

Economical harvesting of electrical energy on a large scale considering the environmental issues is a challenge. As a solution, Microgrids (MGs) promise to facilitate the widely penetration of renewable energy sources (RESs) and energy storage devices into the power systems, reduce system losses...

The paper presents shortly some optimization models of energy system operation and expansion that have been created at the Energy Systems Institute of the Siberian Branch of the Russian Academy of Sciences. Consideration is given to the optimization models of energy development in Russia, a...

This work deals with using a method of artificial intelligence, mainly the generic probabilistic meta-algorithm can be used in such a difficult task which is analyzed and control of dynamical systems. Simulated annealing (SA) is used in this investigation. The adaptive control system was used in...

Fuzzy Linear Programming (FLP) approach is an effective approach that has not been attended extensively by research and academic centers in energy planning field up to now. It seems that this inattention roots in some unknown and uninvestigated grounds about this approach that should be...

Energy resource planning in rural is a powerful tool for sustainable development. A fuzzy goal programming approach is used for rural energy resource allocation for heating and cooking. The detail survey has been conducted to determine the potential of biogas and biomass and to find energy...

In Italy, nuclear power is currently on the agenda of the national government. After abandoning nuclear energy 20 years ago, Italy has not had any direct experience since. Besides its social acceptance and the problem of handling radioactive waste, the economic appraisal of nuclear energy...
