Combining the assessments interview with the Company' resources, infrastructure and IT structures, it is possible to establish a current level of the company. The mapping step is followed by a gap and process analysis, assessing most relevant areas for the creation of value aiming at constructing an interventions roadmap, setting out priorities and activities to be improved. The selection of the improvement areas defines process initiatives, KPIs and interventions to improve business alignment.
To provide a practical view of the methodology a sample of the Value Modeler tool is presented and discussed.

Das betriebliche Kompetenzmanagement steht daher heute mehr denn je vor der Herausforderung die Transformation der betrieblichen Prozesse zu antizipieren, um die Kompetenzentwicklungsprozesse proaktiv zu gestalten. The implementation of Industry 4. Operational competence management is nowadays more than ever faced with the challenge of anticipating the transformation of operational processes in order to proactively design competence development processes. This article presents the industry-specific competence model for operative logistics which describes the status quo as well as prospective competence requirements within operative logistics and demonstrates its application using the example of "spare parts logistics".
Solutions based on concepts and technologies of the "Internet of Things" or "cyber physical systems" can be used to implement monitoring as well as self-organization of production, maintenance or logistics processes. However, integration of new digital tools in existing heterogeneous manufacturing IT systems and integration of machines and devices into manufacturing environments is an expensive and tedious task.
Therefore, integration issues on IT and manufacturing level significantly prevent agile manufacturing. Especially small and medium-sized enterprises do not have the expertise or the investment possibilities to realize such an integration. The objective is to develop and implement a lightweight and easy-to-use integration solution for small and medium-sized enterprises based on recent web automation technologies. MIALinx aims to simplify the integration using simple programmable, flexible and reusable "IF-THEN" rules that connect occurring situations in manufacturing, such as a machine break down, with corresponding actions, e.
For this purpose, MIALinx connects sensors and actuators based on defined rules whereas the rule set is defined in a domain-specific, easy-to-use manner to enable rule modeling by domain experts. Through the definition of rule sets, the workers' knowledge can be also externalized. Using manufacturing-approved cloud computing technologies, we enable robustness, security, and a low-effort, low-cost integration of MIALinx into existing manufacturing environments to provide advanced digital tools also for small and medium-sized enterprises.
Giannetti, Cinzia; Ransing, Rajesh S. The goal is to increase profits by dramatically reducing the occurrence of unexpected process results and waste. ISO defines risk as effect of uncertainty. In the 7Epsilon context, the risk is defined as effect of uncertainty on expected results. The paper proposes a novel algorithm to embed risk based thinking in quantifying uncertainty in manufacturing operations during the tolerance synthesis process. This method uses penalty functions to mathematically represent deviation from expected results and solves the tolerance synthesis problem by proposing a quantile regression tree approach.
The latter involves non parametric estimation of conditional quantiles of a response variable from in-process data and allows process engineers to discover and visualise optimal ranges that are associated with quality improvements. In TSJ 11 Industrie 4. The mathematical formulation presented in this paper will allow organisations to extend Six Sigma process improvement principles in the Industry 4.
Main features of these systems are the real-time data exchange between various technical and computational elements enabled by communication technologies and data processing ability provided by embedded systems. In the area of manufacturing, this trend boosts the development of cyber-physical production systems CPPS. They enable the optimization of control processes, for example by autonomous decision-making, computational assistant systems for workers, or an extended human-machine collaboration. Subsequently, this increased computerization and automation provokes changes for human work in manufacturing.

Following leading experts, the factories of the future will provide less easy and repetitive but more advanced and complex tasks. This trend changes the way how human factors or human-machine interaction influence the design of manufacturing systems. In order to achieve the promised productivity gains created by CPPS, these human-related topics have to be considered and included into the technical and organizational development of CPPS. As a starting point, a detailed view on remaining and newly added human tasks in CPPS is necessary. In this paper, we provide a listing of human task areas in existing and future CPPS.
In this regard, we provide a trend estimation on the decline, rise, or further change of these tasks. The results can be used to facilitate the integration of human factors in the design of CPPS. We carry out our work by firstly deriving a standard listing of tasks for a generalized manufacturing system.
Secondly, we combine the findings with expert judgments regarding CPPS trends and recent employment data from the German job market. Francalanza, E. This dynamic nature of customer requirements has been described as a constantly moving target, thus presenting a significant challenge for several aspects of product development.
To deal with this constant and sometimes unpredictable product evolution, cyber physical production systems CPPS that employ condition monitoring, self-awareness and reconfigurability principles, have to be designed and implemented. This approach aims to minimise or avoids future consequences and disruptions on the CPPS. This knowledge needs to be provided at the right time whilst not being intrusive to the production system designer's cognitive activity.
To effectively deal with the complexity of the cyber physical production system design activity with a manual method would lead to a time consuming, and complex support tool which is hard to implement, and difficult to use. The CPPS design approach has therefore been implemented in a prototype digital factory tool. This paper describes in detail the system requirements and system architecture for this tool. In order to establish the effectiveness of the proposed approach for designing cyber physical production systems, the prototype digital factory tool has been evaluated with a case study and a number of semi-structured interviews with both industrial and scientific stakeholders.
The encouraging results obtained from this research evaluation have shown that such an approach for supporting the CPPS design activity makes stakeholders aware of their decision consequences and is useful in practice.
This result can lead the way for the development and integration of such knowledge-based decision-making approaches within state-of-theart digital factory and Computer Aided Engineering Design CAED tools. Durao, Luiz Fernando C. The integration of modern Internet technologies enables distributed production using AM on a global scale and conditioning monitoring of machines and processes. The manufacturing of products distributed in locations closer to the final usage point may have several advantages, such as reduced logistics costs and reduced inventory levels over the supply chain.
However, distributed manufacturing imposes many challenges on standards, quality control and information management across different manufacturing sites.
The potential benefits and the difficulties are increased when considering the high value added spare parts market. To supply ad hoc demand in diverse locations, inventory and logistics costs are comparatively high. The advent of Industrie 4.
The aim of this paper is to discuss the technical aspects involved in the conception and implementation of distributed manufacturing use cases based on AM. These use cases have been developed with design and engineering - providing the product model - in Germany, and the AM site - providing the manufacturing structure and machines in Brazil, together forming a distributed development and manufacturing network. Four implemented use cases demonstrate the potential of the approach developed, varying the degree of information control of the central factory over the production.
One critical aspect of advanced manufacturing is how to incorporate realtime demand information with a manufacturer's resource information, including workforce data and machine capacity and condition information, among others, to optimally schedule manufacturing processes with multiple objectives. In general, optimized manufacturing scheduling is a non-deterministic polynomial-time hard problem.
