Establishes an optimization model for the combined cooling heating and power(CCHP)system with expected value of annual cost as objective function. With a hotel example,studies the influence of uncertain demands on facility scheme and economical efficiency of CCHP system. The result shows that the uncertainty of demands affect the core facilities slightly while affect the assistant facilities largely,and w...
