To effectively express the protective engineering space object, and effectively support various topology operation and military damage applications, a component-based entity model design scheme and its quality was proposed for the active load section of protective engineering. According to the design variety and validity confirmation in component-based protective engineering entity model, the positive and negative ideal intuitionistic fuzzy design project was determined, and respectively comparing the distance from the design project to the positive and negative ideal project, the superiority degree model was established for the component-based entity model design projects, which further gained the sequence of such projects. Case showed that model effectively solved the decision-making problem about entity model design operations, which provided one theory and method for scientific decision-making practice in entity model design operation for such active load section of protective engineering.
