Purpose – The purpose of this paper is to solve the maintenance management problems of generating units under the reliability criterion. Design/methodology/approach – The problem has been formulated as a combinatorial optimization task, with explicit and simultaneous treatment of multiple...

Purpose: Generation scheduling (GS) is the most prominent and hard-hitting problem in the electrical power industry especially in an integrated power system. Countless techniques have been used so far to solve this GS problem for proper functioning of the units in the power system to dispatch...

Purpose – The purpose of this paper is to solve commitment problem of generating units in thermal power plants and to find the optimal dispatches of the committed units. Design/methodology/approach – The unit commitment (UC) problem has been solved in two stages. In the first stage, the...

Purpose – The purpose of this paper is to solve the optimal power dispatch problem of thermal generating units with cubic fuel cost and emission functions. Design/methodology/approach – The proposed Simplified Direct Search Method (SDSM) is developed from the Direct Search Method (DSM) that...

A linear Fresnel concentrating solar device was developed and its performance was studied. Various combinations of reflecting mirrors were tried to achieve the temperature at focus. A tubular absorber made from aluminium pipe (0.075 m diameter and 0.53 m long) filled with Hytherm-500 oil was...

Integrable evolution equations can take several equivalent forms in a geometrical sense. Here we consider the equivalence of generalized versions involving linear inhomogeneities of three important nonlinear evolution equations, namely the Hirota, Heisenberg ferromagnetic spin and...

This paper has the objective of improving on the issue of forecasting new housing construction, and highlights differences between space demand and investment demand in housing markets. Further, it indicates how these differences will affect construction decisions. The first step is to identify...
