Zusammenfassung:	The invention discloses an operation optimization decision-making method for a gas-steam combined cycle unit, and belongs to the technical field of gas turbines. The operation optimization decision-making method for the gas-steam combined cycle unit comprises the following steps: step 1, mining and processing data in a distributed control system of the gas-steam combined cycle unit, and summarizing effective operation data; step 2, decomposing layer by layer based on a calculation relationship and a mechanism relationship of the operation parameters of the gas-steam combined cycle unit, and carrying out classification processing on the effective data; step 3, combining the classified effective data, and carrying out calculation processing by utilizing a performance calculation principle and a consumption difference analysis principle; step 4, drawing the optimal operation mode graph or curve graph according to a calculation result; and step 5, feeding back to an operation center through an information network
