Global energy model GEM-10R has been used to analyse the possible conditions and scale of using space and terrestrial solar power plants in the long-term perspective (up to the end of the 21st century). Different external conditions, when these alternative energy technologies may be feasible,...

An approach to the solution of decision problems that is based on the computation and analysis of the pay-off matrix is presented. Special Wald, Laplace etc. criteria, as well as subjective probability estimations are applied. The technique is illustrated with an example drawn from designing...
