Product price calculation system of LNG (Liquefied Natural Gas) receiving station

The invention discloses a product price calculation system of an LNG (Liquefied Natural Gas) receiving station. The product price calculation system comprises a data input module, a calculation module and a data output module which are connected in sequence, wherein the data input module is used for inputting project basic data and each tax rate needed by project evaluation; the calculation module comprises an economic indicator calculation module, a project economic model, a price calculation module, a mode converter module and a process controller module; the project economic model is connected with the economic indicator calculation module and the price calculation module; the mode converter module is connected with the project economic model; the process controller module is connected with the price calculation module; the data output module is used for outputting a calculation result; all the modules are arranged in the system. The system disclosed by the invention can be used for calculating a product price according to an indication value of economic evaluation. A price calculation process adopts an iteration method with the very strong commonality and is not sensitive to a function relation between a price and an indicator; a calculation rule does not need to be changed aiming at different pre-set indicators.
