Supporting Digital Production, Product Lifecycle and Supply Chain Management in Industry 4.0 by the Arrowhead Framework xe2x80x93 a Survey While Industry 4.0 targets are theoretically set from various aspects, the approaches for covering some of its key areas are heterogeneous. The main pillars for Productive4.0 xe2x80x93 a European research initiative with the industrial drive xe2x80x93 are Digital Production, Product Lifecycle Management and Supply Chain Management. These are also key areas for Industry 4.0, and so far handled with heterogeneous approaches, toolsets xe2x80x93 and success, indeed.This paper has two aims. First, to provide an overview of the stateoftheart concepts regarding these three areas, filtered through the actual industrial requirements. Second, to survey the Arrowhead Framework concerning these areas, and suggest a homogeneous approach that can support not only the main vision of these three domains but the actual designtime and operationaltime tasks needed to make the vision of Industry 4.0 reality.

Approach for Implementing Industry 4.0 Framework in the Steel Industry The advancements of the Steel Industry require a fully integrated manufacturing and business system for realtime decision making. The main challenge in the Steel Industry is the disconnection between the shop floor systems such as Manufacturing Execution System (MES) and business systems such as Enterprise Resource Planning (ERP). The production process of Steel Industries requires visibility of operations, planning and scheduling, lead times, quality management, machine health, maintenance planning, to name but a few aspects. This study investigates current technologies and investments employed by steel companies and how to leverage these existing investments to attain a smart enterprise and subsequently manage current and future steel demands efficiently. Industry 4.0 simplifies the approach to implement complex systems in a structured and logical manner in manufacturing organisations. This paper deliberates the Industry 4.0 framework and the path to implement Industry 4.0 in the steel sector.
