Introduction

Objectives


In an industrial environment we quite often need to

  • describe an industrial plant consisting of a bunch of different parts, each having a certain purpose and set of properties, and which are related in various ways
  • manage process or maintenance data of the plant and its features
  • do a high-performance cost-benefit analysis and create key performance indicators

Therefore we need to

15 px „Dissemble“ the system into theoretical blocks representing the real as well as intangible parts of the system.
15 px Identify the necessary properties of the block.s
15 px Think about how blocks are possibly related to each other.
15 px Think about the functions and features of blocks.
