The invention provides a nuclear
energy engineering construction performance calculation method and
system and a readable storage medium, and the method comprises the steps: carrying out the coding of a project amount, and enabling a code to at least comprise a type code used for identifying the type of the project amount; selecting a corresponding entity
engineering quantity metering model according to the type code, wherein the metering model comprises a first model for a bulk item class and a second model for an equipment module class; on the basis of the selected metering model, entity
engineering quantity data are collected,
nuclear engineering exclusive correction factors are introduced for
coupling calculation, so that an entity
engineering performance value is obtained, and the correction factors comprise a quality compliance factor, a technical difficulty factor and a security
constraint factor; comparing the entity engineering performance value with a plan reference to obtain a completion deviation rate; dynamically correcting the management performance initial value by using the completion deviation rate to obtain a
construction management performance value; and performing weighted
coupling on the entity engineering performance value and the
construction management performance value, and outputting a comprehensive performance value P.
