Abstract

In dynamic production environments, bringing flexibility to production planning and control (PPC) against continuously changing requirements is key to fulfill production objectives. Such environments often involve various information systems that make the integration of knowledge on the current state of production more challenging. In this paper, we present a conceptual approach of Digital Shadows that allow for a holistic data view on PPC-specific tasks based on an ontology, serving as a knowledge base of semantic-enriched data and production constraints. An exemplary real-world application for PPC in injection molding demonstrates the benefits of the concept. • Stakeholders in PPC are overwhelmed with information from less interlinked IT system. • Digital Shadows are a promising approach to support decisions in PPC. • Concept of Digital Shadows for Production Planning and Control. • Decision support provided through purpose driven information generation. • Exemplary concept application for minimizing rejection rates in injection molding.
