Refine schedule and budget estimates based on details of the design model.

基于设计模型的细化时间进行计划和预算的预估。

Model is built by constraints of develop cost and schedule in the example fire control radar conceptual design, calculational conclusion demonstrates the effectiveness of the proposed model.

最后以火控雷达的概念设计为例，以研制费用和研制进度为约束条件建立模型，计算说明此模型是有效的。

Modeling steps: confirm design scheme, model parts, assemble part, edit unit store and make schedule drawing.

造型过程含确定设计方案、零件造型、零件装配、编辑零件库、生成工程图等步骤。
