Using Operation Process Simulation for a Six Sigma project of Mining and Iron Production Factory
2008 Winter Simulation Conference, 2008Co-Authors: Undram Chinbat, Soemon TakakuwaAbstract:The use of the Operation Process Simulation (OPS) for Six Sigma Projects (SSP) can illustrate visual display of the Process by enabling to define, measure, analyze and improve the current Process virtually but realistically. This paper investigates the quantitative benefits of using the Design for Six Sigma (DFSS) technique for a SSP in a Mining and Iron Production Factory (MIPF). The DFSS was deployed through five distinct phases: DMAIC, for optimizing the current MIPF as a first part of the research. The second part of the research investigates the possibilities of developing the deliverables of the DMAIC for a DMADV for implementing a new MIPF. Use of the OPS in all phases of the DMAIC has provided highly effective and accurate prediction for Factory Process improvement. Furthermore, the paper explored the effective possibilities of developing the deliverables of the DMAIC for the DMADV for building new MIPF.

the three generations of field level networks evolution and compatibility issues
IEEE Transactions on Industrial Electronics, 2010Co-Authors: Thilo SauterAbstract:Field-level networks have been one of the keys to modern automation systems. Be it in Factory, Process, or building automation, networks allow for horizontal and vertical integration of distributed devices and functions. This paper reviews the evolution of field-level networks comprising fieldbus systems, industrial Ethernet, and recent industrial wireless networks. The main focus is on demonstrating the continuity in the development of the three generations that ensured backward compatibility at the expense of radical innovation. Given the wide set of modern communication technologies, this paper then discusses how architectures for future automation networks might look. Particular emphasis is put on hybrid architectures for combined wired/wireless networks. A generic concept for integration of multiple wireless segments will be presented that supports seamless roaming for mobile nodes in industrial environment.

The Role of User Guidance in the Industrial Adoption of MDE Approach
Electronic Communication of The European Association of Software Science and Technology, 2011Co-Authors: Jari Rauhamäki, Outi Laitinen, Seppo Sierla, Seppo KuikkaAbstract:Model-Driven Engineering (MDE) has emerged as an actively researched and established approach for next generation control application development. Technology transfer to the industry is a topical research problem. Since most professional Factory Process control engineers do not have computer science backgrounds, there is an urgent need for studies of the role of user guidance in the professional learning, and thus, of industrial adoption of MDE approaches. In this study professionals were invited to a hands-on assessment of the AUKOTON MDE approach for Factory Process control engineering. Qualitative empirical material was collected and analyzed to identify the role of user guidance in the context of other factors impacting industrial adoption. Challenges in adoption that could be solved by user guidance were identified with the theory of organizational knowledge creation (SECI) model.

integration of biopolymer production with Process water treatment at a sugar Factory
New Biotechnology, 2014Co-Authors: Simon Anterrieu, T. Alexandersson, Luca Quadri, Inez Dinkla, Simon Bengtsson, Anton Karlsson, Monica V Arcoshernandez, Fernando Morgansagastume, Bert Geurkink, Mattias HjortAbstract:The present investigation has focused on generating a surplus denitrifying biomass with high polyhydroxyalkanoate (PHA) producing potential while maintaining water treatment performance in biological nitrogen removal. The motivation for the study was to examine integration of PHA production into the water treatment and residuals management needs at the Suiker Unie sugar beet Factory in Groningen, the Netherlands. At the Factory, Process waters are treated in nitrifying–denitrifying sequencing batch reactors (SBRs) to remove nitrogen found in condensate. Organic slippage (COD) in waters coming from beet washing is the substrate used for denitrification. The full-scale SBR was mimicked at laboratory scale. In two parallel laboratory scale SBRs, a mixed-culture biomass selection strategy of anoxic-feast and aerobic-famine was investigated using the condensate and wash water from Suiker Unie. One laboratory SBR was operated as conventional activated sludge with long solids retention time similar to the full-scale (SRT >16 days) while the other SBR was a hybrid biofilm-activated sludge (IFAS) Process with short SRT (4–6 days) for the suspended solids. Both SBRs were found to produce biomass with augmented PHA production potential while sustaining Process water treatment for carbon, nitrogen and phosphorus for the Factory Process waters. PHA producing potential in excess of 60 percent g-PHA/g-VSS was achieved with the lab scale surplus biomass. Surplus biomass of low (4–6 days) and high (>16 days) solids retention time yielded similar results in PHA accumulation potential. However, nitrification performance was found to be more robust for the IFAS SBR. Assessment of the SBR microbial ecology based on 16sDNA and selected PHA synthase genes at full-scale in comparison to biomass from the laboratory scale SBRs suggested that the full-scale Process was enriched with a PHA storing microbial community. However, structure–function relationships based on RNA levels for the selected PHA synthases could not be established and, towards this ambition, it is speculated that a wider representation of PHA synthesases would need to be monitored. Additionally at the Factory, beet tail press waters coming from the Factory beet residuals management activities are available as a carbon source for PHA accumulation. At pilot scale, beet tail press waters were shown to provide a suitable carbon source for mixed culture PHA production in spite of otherwise being of relatively low organic strength (≤10 g-COD/L). A copolymer of 3-hydroxybutyrate with 3-hydroxyvalerate (PHBV with 15% HV on a molar basis) of high thermal stability and high weight average molecular mass (980 kDa) was produced from the beet tail press water. The mixed culture accumulation Process sustained PHA storage with parallel biomass growth of PHA storing bacteria suggesting a strategy to further leverage the utilization of surplus functional biomass from biological treatment systems. Integration of PHA production into the existing Factory water management by using surplus biomass from condensate water treatment and press waters from beet residuals Processing was found to be a feasible strategy for biopolymer production.
