1. A method of manufacturing a ceramic matrix composite (CMC) component, the method comprising:
manufacturing a plurality of parts;
determining corresponding weights of the plurality of parts;
determining a plurality of target weights corresponding to a plurality of manufacturing stages of the CMC component; and
performing the plurality of manufacturing stages, wherein each manufacturing stage comprises:
layering at least one ply on a mandrel if a current manufacturing stage is a first manufacturing stage from the plurality of manufacturing stages;
layering at least one ply on the CMC component formed in an immediately preceding manufacturing stage from the plurality of manufacturing stages if the current manufacturing stage is any manufacturing stage subsequent to the first manufacturing stage;
determining an intermediate weight of the CMC component after layering the at least one ply in the current manufacturing stage;
determining a first weight difference between the intermediate weight of the CMC component and a corresponding target weight from the plurality of target weights, the corresponding target weight corresponding to the current manufacturing stage;
determining a second weight difference between the first weight difference and the corresponding weight of each of the remaining parts from the plurality of parts;
selecting at least one part from the remaining parts for which the second weight difference is minimum among the remaining parts; and
disposing the selected at least one part on the at least one ply layered in the current manufacturing stage.
