Laying the foundations on which to build the cyber-physical world of the Fourth Industrial Revolution comes down to creating a unified platform for transforming existing information solutions to ones, that meet the requirements and capabilities of the new integrated world. The RAMI 4.0 standard aims to introduce the concept of “asset” as part of the cyber -physical world, as well as to describe the hierarchical structure of assets in an industrial enterprise during their life-cycle. A similar purpose has another standard – IEC/EN 62264, which describes the operations resources as objects for integration of information between information systems of different h ierarchical levels, as well as models of operational activities for definitions, planning, execution and collecting and analyzing information on these resources.

The ANSI/ISA-95 (ISO 62264) standard is a key concept driving the implementation of Industry 4.0 in industry. It is a backbone of the Reference Architectural Model for Industry 4.0 (RAMI 4.0) and describes the objects, models and activities on operations management hierarchy level (Level 3). A major model described in the standard is the Planning model, in which is described that the planning activities rely on requirements of personnel, equipment and/or material. Also, a general concept in all models, described in the standard is the process segment that may refer as a combination of specific equipment/asset (with enough capability), a material (with specific quality) and/or a person (with proper qualification). In this article the Segment Dependencies impact on Capacity and Planning models is examined and some conclusions are made.
