Abstract
The paper presents a framework for considering resilience as an integrated aspect in the design of manufacturing systems. The framework comprises methods for the assessment of resilience, supply chain and production planning, flexible execution and control as well as modular and skill-based methods for automation systems. A basic classification of risk categories and their impacts on manufacturing environments is given so that a concept of reconfigurable and robust production systems can be derived. Based on this, main characteristics and concepts of resilience are applied to manufacturing systems. As a lever of increased resilience on business and supply chain level, options for synchronized production planning are presented in a discrete event simulation. Furthermore, a concept to increase resilience on the level of business process execution is investigated, allowing manufacturing tasks to be rescheduled during runtime using a declarative approach to amend conventional business process models.
Highlights
The paper closes with a discussion on the most critical aspects from the presented works, which are related to the representation of complex and interrelated information as well as the derivation of matrix production as a future-oriented and resilient manufacturing system concept
Manufacturing systems require a digital counterpart to enable fast commissioning, optimization, and controller code review in parallel to the production process. All of these aspects diffuse into a “framework for resilient manufacturing systems”, which will be explained in detail
With the example of a model machine that allows for rescheduling the tasks performed by its modules, we examine how resilience can be provided on the level of process execution
Summary
The anticipation, prevention, and mitigation of risks and their corresponding threats are an inherent part of decision making in economy and industry. It suggests the standardized automation pyramid and its corresponding reference architecture model 4.0 as a guideline that covers the relevant levels for production system description and the corresponding solutions that are presented afterwards. It is completed with specific sections of measures for resilience improvements, starting from the supply chain and enterprise down to field level. The paper closes with a discussion on the most critical aspects from the presented works, which are related to the representation of complex and interrelated information as well as the derivation of matrix production as a future-oriented and resilient manufacturing system concept
