text: In manufacturing systems with a job shop organization, queues between workstations
create an intermittent process flow, allowing workers to schedule tasks entering
the queue based on their needs and preferences. The resulting scheduling autonomy
of individual workers often leads to inefficiencies in the overall production
process due to the loss of control. Companies are therefore increasingly using
algorithmic scheduling systems to assign task sequences to workers, thereby drastically
reducing their autonomy and negatively affecting their job performance and well-being.
This paper extends the existing flexible job shop scheduling problem by sequencing
preferences (FJSPSP) to incorporate a human-centered perspective by predicting
workers’ task sequencing decisions using learning-to-rank (LTR) methods. By learning
workers’ individual task sequencing preferences, it becomes possible to predict
the processing sequence based on task characteristics. The scheduling algorithm
for the FJSPSP presented in the paper incorporates workers’ learned sequencing
preferences as constraints. Considering workers’ learned task sequencing decisions,
the FJSPSP optimizes only task assignments to maintain workers’ autonomy over
task sequences. The contributions of this paper are fourfold, namely, (1) presenting
an approach to elicit sequencing decision datasets from workers, (2) demonstrating
the successful prediction of humans’ and an actual worker’s task sequencing decisions
with LTR, (3) formulating the FJSPSP variant that integrates workers’ sequencing
preferences as constraints and proving its effectiveness in a simulation study,
and (4) consolidating these steps into an explainable artificial intelligence
(XAI)- and LTR-enabled sociotechnical system design framework. The paper closes
with a discussion of the overall methodology and future research perspectives.

text: In weakly-structured work processes, workers are free to decide in which sequence
to process their tasks. Predicting their decision-making helps plan production
more accurately while preserving workers’ autonomy. The factors that influence
workers’ decision-making depend on the manufacturing process and person considered,
and they must be newly collected for each use case. This paper identifies the
factors influencing workers when deciding in which sequence to process manufacturing
tasks in a medium-sized hydraulic cylinder manufacturer. Five workers and two
lead workers were observed and interviewed during several work shifts about influencing
factors. The authors propose a new interview technique called indifference testing
to overcome subjects’ difficulty articulating their decision-making process. Collected
factors were categorized using inductive category formation and context analysis.
The analyses identified 75 influencing factors comprising 37 decision attributes
and 38 decision rules. The identified decision attributes indicate that worker
preferences are influenced by attributes from the classical scheduling literature
and attributes related to worker well-being, circadian rhythms, and ergonomics.
The identified decision rules are useful constituents of more complex preference
functions. The decision attributes and rules enable the construction of machine
learning models to predict workers’ task sequencing decisions in job shops. Potential
applications include systematically eliminating or controlling influencing factors
through workplace design measures to increase worker well-being and optimality
of their decisions.

text: In einer humanzentrierten Kleinserien- und Einzelfertigung mit Werkstattorganisation
verfügen Fertigungsmitarbeitende häufig über eine hohe Autonomie und Entscheidungsfreiheit.
Das Zusammenspiel individueller Planungsstrategien von Mitarbeitenden innerhalb
eines Fertigungsprozesses kann sich positiv als auch negativ auf das Erreichen
der produktionslogistischen Zielgrößen auswirken. In diesem Beitrag wird eine
Variante des Flexible Job Shop Scheduling Problems vorgestellt, welches das Entscheidungsverhalten
autonomer Arbeitspersonen bezüglich der Bearbeitungsreihenfolgebildung berücksichtigt.
Weiterhin wird die Ableitung arbeitsorganisatorischer Gestaltungsempfehlungen
durch die Analyse individueller Planungsstrategien von Arbeitspersonen mittels
Methoden der erklärbaren künstlichen Intelligenz demonstriert. Betrachtungsgegenstand
der Analyse ist die Entscheidung von Arbeitspersonen, in welcher Reihenfolge sie
ihre täglichen Aufgaben abarbeiten. Der Beitrag schließt mit einer Diskussion
über die Nutzung der vorgestellten Verfahren zur Ableitung von arbeitsorganisatorischen
Gestaltungsempfehlungen.

text: "Microbial food safety is the master key for reducing illness caused by the
consumption of foodstuffs. This demonstration therefore aims to use non-pathogenic
surrogates to draw conclusions whether vegan ready-to-eat model food serves as
a base for growth of pathogenic Escherichia coli and Listeria monocytogenes in
vegan ready-to-eat meat substitute in case of a potential contamination, causing
a reduction of food safety.\r\nPackages of ready-to-eat vegan meat substitutes
were inoculated with certain level of non-pathogenic L. innocua and E. coli and
incubated at varying environmental conditions before they were examined for changes
in the physico-chemical properties.\r\nThe observed ability of the microbes to
grow in the snacks may cause a reduction in food safety. This demonstration shows
that these ready-to-eat-snacks may cause a reduction in food safety if the product
studied is contaminated."

text: 'To evaluate the suitability of an analytical instrument, essential figures
of merit such as the limit of detection (LOD) and the limit of quantification
(LOQ) can be employed. However, as the definitions k nown in the literature are
mostly applicable to one signal per sample, estimating the LOD for substances
with instruments yielding multidimensional results like electronic noses (eNoses)
is still challenging. In this paper, we will compare and present different approaches
to estimate the LOD for eNoses by employing commonly used multivariate data analysis
and regression techniques, including principal component analysis (PCA), principal
component regression (PCR), as well as partial least squares regression (PLSR).
These methods could subsequently be used to assess the suitability of eNoses to
help control and steer processes where volatiles are key process parameters. As
a use case, we determined the LODs for key compounds involved in beer maturation,
namely acetaldehyde, diacetyl, dimethyl sulfide, ethyl acetate, isobutanol, and
2-phenylethanol, and discussed the suitability of our eNose for that dertermination
process. The results of the methods performed demonstrated differences of up to
a factor of eight. For diacetyl, the LOD and the LOQ were sufficiently low to
suggest potential for monitoring via eNose. '

text: Natural ventilation in a building is an effective way to achieve acceptable
indoor air quality. Ventilation dilutes contaminants such as bioeffluents generated
by occupants, substances emitted from building materials, and the water vapor
generated by occupants’ activities. In a building that requires heating and cooling,
adequate ventilation is crucial to minimize energy consumption while maintaining
healthy indoor air quality. However, measuring the actual magnitude of the natural
ventilation rate, including infiltration through the building envelope and airflow
through the building openings, is not always feasible. Although international
and national standards suggested the required ventilation rates to maintain acceptable
indoor air quality in buildings, they did not offer action plans to achieve or
evaluate those design ventilation rates in buildings in use. In this study, the
occupant-generated carbon dioxide (CO2) tracer gas decay method was applied to
estimate the ventilation rates in an office room in Seoul, South Korea, from summer
to winter. Using the method, real-time ventilation rates can be calculated by
monitoring indoor and outdoor CO2 concentrations without injecting a tracer gas.
For natural ventilation in the test room, 145 mm-diameter circular openings on
the fixed glass were used. As a result, first, the indoor CO2 concentrations were
used as an indicator to evaluate how much the indoor air quality deteriorated
when all the windows were closed in an occupied office room compared to the international
standards for indoor air quality. Moreover, we found out that the estimated ventilation
rates varied depending on various environmental conditions, even with the same
openings for natural ventilation. Considering the indoor and outdoor temperature
differences and outdoor wind speeds as the main factors influencing the ventilation
rates, we analyzed how they affected the ventilation rates in the different seasons
of South Korea. When the wind speeds were calm, less than 2 m/s, the temperature
difference played as a factor that influenced the estimated ventilation rates.
On the other hand, when the temperature differences were low, less than 3 °C,
the wind speed was the primary factor. This study raises awareness about the risk
of poor indoor air quality in office rooms that could lead to health problems
or unpleasant working environments. This study presents an example of estimating
the ventilation rates in an existing building. By using the presented method,
the ventilation rate in an existing building can be simply estimated while using
the building as usual, and appropriate ventilation strategies for the building
can be determined to maintain the desired indoor air quality.

text: Especially in highly interdisciplinary fields such as automation engineering,
contemporary programming education with tailored assignments and individual feedback
is a major challenge for educational institutions due to the increasing number
of students per teacher and the ever-increasing demand for computer science professionals.
To address this gap, we present ”KIAAA” an AI Assistant for Automation Engineering
Teaching, a work-in-progress approach for an integrated, customized, and AI-based
learning support system for automation and programming courses based on instructor-defined
course objectives. Thereby in the KIAAA system, the individual knowledge level
of the students is determined and individually tailored virtual learning scenarios
are generated based on the knowledge and learning profile of the students. These
are iteratively adapted based on the answers given. To achieve this, KIAAA uses
several AI components, a hybrid rule-based scenario generation component, a Help-DKT-based
cognitive model, and a solution assessor that uses a combination of traditional
code analysis methods and AI-based analyses methods for automated programming
task assessment. These components are the main parts of KIAAA to generate customized
programming scenarios as well as visualization and simulation based on a modern
game and physics engine.

text: Low voltage direct current microgrids (DC-MG) provide a solution for increased
efficiency by the reduction of conversion losses, total reuse of recuperation
energy and an increased share of local power generation. Especially industrial
applications ask for high uptimes and a stable voltage supply, which are both
at stake in a power grid dominated by renewable generation. DC-MGs overcome these
drawbacks by balancing energy distribution and power demand locally. For the planning
and design of these grids a systemic approach is needed, due to the fact that
many components are interacting. The task arises of structuring the knowledge
available for individual technologies in an overall design framework. For this
purpose, current state-of-the-art design processes are discussed in this article.
These processes are mapped into the context of the requirements in an industrial
environment. The findings are transferred to the design of industrial DC networks.
Finally, a complete design process for DC-MGs is derived, which is proposed as
a basis for the development of tools.

text: An open industrial DCgrid for energy supply has many benefits. Also new challenges
arise by coupling the DClink capacitors of all devices, e.g. inverters. This paper
presents the effects of component failures causing short circuit faults in combination
with electrically coupled and charged DClink capacitors. Resulting energy flows
are shown, which arise in the DCgrid in case of faults. In addition, measurements
of short circuit tests and two solutions are shown, which enable the safe and
simple operation of an open industrial DCgrid.

text: Stachybotrys (S.) chartarum is a cellulolytic mould with the ability to produce
highly cytotoxic macrocyclic trichothecenes. Two chemotypes are defined according
to their ability to produce either atranones or satratoxins. S. chartarum has
been well known as the causative agent of the lethal disease stachybotryotoxicosis
in horses. Further investigations revealed that this disease is strictly correlated
with the presence of macrocyclic trichothecenes. Furthermore, their occurrence
in water-damaged buildings has been linked to adverse health effects such as the
sick building syndrome. As the chemotypes cannot be characterized via phenotypic
criteria, different methods such as PCR, MALDI–TOF MS, LC–MS/MS, thin-layer chromatography
and cytotoxicity assays have been used so far. Fourier-transform-infrared spectroscopy
(FT-IR) is commonly used for the differentiation of bacteria and yeasts, but this
technique is also applicable to filamentous fungi. Hence, this study aimed at
evaluating to which extent a reliable differentiation of S. chartarum chemotypes
A and S is possible. Besides, another objective was to verify if the recently
introduced third genotype of S. chartarum can be identified. Therefore, 28 strains
including the two chemotypes and the third genotype H were cultivated on malt
extract agar (MEA) and potato dextrose agar in three biological replicates. Each
sample was applied to FT-IR measurements on day 7, 14 and 21 of cultivation. In
this study, we achieved a distinction of the chemotypes A and S via FT-IR spectroscopy
after incubation for 7 days on MEA. In terms of genotype differentiation, the
PCR detecting satratoxin- and atranone-gene clusters remained the only applicable
method.

text: An open industrial DC grid has a lot of advantages. Also new challenges arise
by coupling several DC link capacitors of inverters. This paper presents an approach
and measurements of an active device protection to withstand possible faults that
can occur in the DC grid. In particular, robustness in the event of faults plays
a key role.

text: In this contribution, the effect of the presence of a presumed inert gas like
N2 in the feed gas on the biological methanation of hydrogen and carbon dioxide
with Methanothermobacter marburgensis was investigated. N2 can be found as a component
besides CO2 in possible feed gases like mine gas, weak gas, or steel mill gas.
To determine whether there is an effect on the biological methanation of CO2 and
H2 from renewable sources or not, the process was investigated using feed gases
containing CO2, H2, and N2 in different ratios, depending on the CO2 content.
A possible effect can be a lowered conversion rate of CO2 and H2 to CH4. Feed
gases containing up to 47N2 were investigated. The conversion of hydrogen and
carbon dioxide was possible with a conversion rate of up to 91 but was limited
by the amount of H2 when feeding a stoichiometric ratio of 4:1 and not by adding
N2 to the feed gas.

text: "Order picking has long been identified as the most labor costly and intensively
activity in warehouse management. The orders from the customers need to be fulfilled
tightly and timely. In order to keep the required high service level, the warehouse
has to increase the picking productivity under the constraints of limited capacity.
This paper concerns a man-togoods order picking system, in which the order pickers
have to drive with a pallet jack to the storage locations. Considering that the
orders are mostly small orders which consist of less lines, it is efficient to
combine severalsingle customer orders into one picking order. Under this circumstance,
this paper intends to answer the question of how customer orders should be grouped
into picking orders with the aim of minimizing the total travel length through
the warehouse. Consequently the productivity of the order picking system can be
improved. An optimization problem for order batching is introduced. The optimization
method of order batching is then proposed. Based on the simulation of different
scenarios of incoming orders, it can be concluded that the developed method is
effective in improving the productivity of the concerned order picking system.\r\n"

text: This paper discusses an alternative to common Powerline or Power-over-Ethernet
applications, combining a 100BASE-TX-equivalent full duplex communication and
simultaneous DC power transmission on one single twisted pair wire. The reduction
of wires and connections can potentially ease the modularity and reconfigurability
of industrial production installations, if the data communication offers a sufficiently
high robustness against influences from the DC power transmission. This part of
our research focuses on the necessary electrical adaptations between data and
power circuitry and evaluates interference scenarios that are common for industrial
fieldbus installations.
