<p><P>PROBLEM TO BE SOLVED: To provide a gas supply method enabling each manufactory, in a gas supply system for supplying gas from a plurality of manufactories, to supply gas with stable property to a specified demander while predicting an area for supplying the gas. <P>SOLUTION: The conduit network of the gas supply system is analyzed in advance, whereby the load flow rate and gas pressure of respective nodes n1-n11 and the flow rate, direction and property of the gas flowing each between nodes are determined. Based on this analysis result, the property of the gas to be supplied to a plurality of nodes provided within the conduit network can be analyzed in advance. The property of the gas to be supplied to a demander who receives it through a specified node can be analyzed in advance. When the gas property to be supplied to a specified node, various measures are executed and analyzed in advance, whereby the gas manufacturing amount and the set value of each facility for supplying the gas with stable property can be easily known. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
