　　First of all, raw materials and manufactured components comprise the initial physical input in the entire manufacturing process.

　　63.原材料与制成部件到位后先需储存以供后续的组装，但是，组装首先需要依靠生产规划阶段。

　　Once raw materials and manufactured components are obtained, they are stored for later assembly, but assembly first depends on the production planning stage.
