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.

Model Understandability

Business process models tend to get more and more complex with age, which hurts the ease with which designers can understand and modify them. Few metrics have been proposed to measure this complexity, and even fewer have been tested in the Business Process Execution Language (BPEL) context. In this paper, we present three related experimental studies whose aim was to analyse the ability of four selected structural metrics to predict BPEL process model understandability and modifiability. We used Spearman’s rho and regression analysis in all three experiments. All metrics passed the correlation tests meaning that they can serve as understandability and modifiability indicators. Further, four of the metrics passed the regression test for understanding time implying that they can serve as understandability predictors. Finally, only one metric passed the regression test for modification time implying that it can serve as a modifiability predictor.

This chapter provides an overview of business process management and business process modeling. We approach business process management by giving a historical classification of seminal work, and define it by the help of the business process management life cycle. Business process models play an important role in this life cycle, in particular, if information systems are used for executing processes. We deduct a definition for business process modeling based on a discussion of modeling from a general information systems point of view. In the following, we detail business process modeling techniques, in particular, modeling languages and modeling procedures for business process modeling. Finally, we discuss some future trends with a focus on the business process execution language for Web services (BPEL), and conclude the chapter with a summary. The chapter aims to cover business process modeling in a comprehensive way such that academics and practitioners can use it as a reference for identifying more specialized works.

Business Process Execution

Purpose Declarative process modelling is a constraint-centric approach that treats business rules as first-class citizens in business process models. Augmenting the declarative process modelling technique with capability to detect the constraint violations during business process execution is of crucial importance. The purpose of this paper is to contribute to the modelling of business rules through a repository of pattern-oriented templates. Design/methodology/approach The semantics of the business rule templates is underpinned by linear temporal logic (LTL). Automated temporal reasoning is then conducted for determining whether process executions adhere to the business rules through the utilisation of the Logics Workbench (LWB). An application of the methodological framework is illustrated by a realistic case study on degree requirements verification. Findings To access the practicality of the approach, the case study of this paper is based on the verification of degree requirements, which is different from the domain area of the case study in the author’s prior work. The findings indicated that the temporal framework could be applied to the declarative process modelling in a consistent and efficient manner. Originality/value This paper is an extended version of the author’s earlier study. More details on the LTL and LWB are provided in the current study. The author introduces 17 new business rule templates and illustrates the utilisation of the new templates via a case study that belongs to a different domain area.

Business Process Execution

Business processes have been widely becoming crucial assets of organisations across various industries and domains. The flexibility in dealing with changes when business processes are executed has significant impact on the success of an organisation's business operations, especially in the current ever-changing business environment. In this context, agent-based systems offer a promisingly powerful platform for business process execution. In this paper, the authors propose an agent-mediated platform for business processes with the aim to contribute to bridge the gap between business process management and agent-oriented development. They present a conceptual mapping method for a seamless transition from business process models in Business Process Modelling Notation (BPMN) to agent-oriented models in the Prometheus methodology, which is implemented using the ATLAS Transformation Language. The authors also developed an Eclipse-based plug-in which allows the designer to import BPMN models into the Eclipse-based Prometheus Design Tool.

Farmed Salmon

The farmed salmon supply chain has a highly complex and integrated structure, where activities occur both in the sea and on land. Due to this complexity, the supply chain needs appropriate decision-support tools to aid the production planning process, which capture the material flows, information flows and behaviours of the decision makers in the chain. This paper proposes a hybrid simulation framework for production planning using the case of the Norwegian Atlantic salmon supply chain. This hybrid simulation comprises agent-based modelling (ABM) to capture the autonomous and interacting decision making behaviour of the supply chain actors, while discrete-event simulation (DES) is employed to model the various production processes within the chain. The simulation is implemented using AnyLogic™ version 8.0 simulation software, using a case study from the Norwegian farmed salmon sector. The proposed modelling framework provides a deeper understanding of the activities in the salmon supply chain, thereby enabling improved decision making.

Kürzere Produktlebenszyklen stellen produzierende Unternehmen in Deutschland vor die Herausforderung, Anläufe häufiger und in immer kürzerer Zeit zu bewältigen. Um dieser Herausforderung zu begegnen, müssen Produktionssysteme im Hinblick auf die Anlaufphase optimiert werden. In Kooperation zwischen dem Werkzeugmaschinenlabor WZL und dem Lehrstuhl für Controlling der RWTH Aachen entstand ein erster Ansatz für soziotechnische Produktionssysteme.   Due to shorter product life cycles, manufacturing companies in Germany have to face the challenge of managing ramp-ups more often and in ever decreasing times. To overcome these challenges, manufacturing systems must be optimized with regard to the ramp-up stage. As a result of the collaboration of the Laboratory for Machine Tools and Production Engineering and the Chair for Management Accounting of the RWTH Aachen university, a first approach for socio-technical manufacturing was developed.

The objective of this research is to develop a new ontology-based approach for the management and control of cyber-physical production systems (CPPSs). In the CPPSs, the management and control functions are integrated with a physical part of manufacturing system. The function of production planning and control of manufacturing systems (PPC) is an important part of the management and control of the CPPSs. The elements of the cyber system structure enable the dynamic management and control of manufacturing systems in real time, through the realization of the digitalized and cybernated functions of PPC. The proposed approach to management and control of the CPPSs is based on the foundational ontology of manufacturing systems. The digitalized production planning, scheduling, and control functions are implemented as a multi-agent system (MAS). The communication between agents was addressed to support the autonomic decision for each individual agent. A case study demonstrates feasibility of the approach through the use of simulation experiments.
