DX in the engineering domain is indispensable in manufacturing, which is becoming increasingly complex. MBSE has been attracting attention as a means of approaching this issue, but many people say that they are unable to grasp the image of its use in actual design. In this lecture, we will explain the positioning and role of MBSE in the manufacturing industry, focus on how MBSE can be utilized in the business process, and introduce a concrete operation flow using Zuken's MBSE solution "GENESYS". If you are considering implementing MBSE, please attend this seminar.
