Opis:
The aim of the article is indicating the advantages of utilizing the synergy obtained by introducing two management methods: Lean Construction and Agile Management using the example of the process of deliveries of concrete mix in road construction. Despite the seemingly contradictory assumptions (Lean Management aims at limiting wastefulness and maximizing the value for the customer and agile management serves for creating the possibility for fast, effective response to non-expected changes thanks to the adopted strategy of flexibility, which usually requires engaging additional resources), both management methods deliver the effect of increasing the effectiveness of the machine laying the pavement. Using a “spaghetti diagram” (one of the tools of Lean Management) led to limiting the time losses during loading and unloading the concrete mix destined for constructing highway pavement. On the other hand, the tactic of technological flexibility in the form of a modification of the concrete mix allowed for broadening the time frame for the delivery of concrete to the construction site to as much as two hours. Moreover, applying the real time delivery management system (in accordance with the assumptions of Construction 4.0) created the possibilities for ensuring quick reacting to the changing conditions of delivery and laying the concrete mix in the pavement and ensuring the appropriate functioning of the machine laying the pavement. The presented examples indicated the advantages of the suggested concept in reference to the traditional solution.
Artykuł poświęcony jest metodzie RMCD4.0, która służy zapewnieniu rytmicznych dostaw mieszanki betonowej w oparciu o model quasi-deterministyczny. Opiera się ona na osiągnięciu synergii dwóch metod zarządzania: Lean Construction (której zadaniem jest zapewnienie ograniczenia marnotrawstwa np. czasu podczas załadunku mieszanki betonowej ) i Agile/Flexible Management (zapewnia możliwość dostosowania do zmian ). Istotne znaczenie ma także zastosowanie idei Construction 4.0 - zapewnienie współpracy dzięki komunikacji bezprzewodowej i możliwości lokalizacji urządzeń transportowych w czasie rzeczywistym. Koordynator procesu produkcji, transportu i wbudowania betonu towarowego bazując na modelu symulacyjnym dostaw steruje środkami transportu w sposób zapewniający rytmiczne dostawy mieszanki betonowej w celu osiągnięcia maksymalnej wydajności maszyny wiodącej - zestawu z układarką nawierzchni betonowej.

Opis:
Based on the payments and settlement system, the influence of the topology of capital flow networks on the extra short-term liquidity demand is investigated. Through modelling the circulating mechanism of liquidity in a network, its different influencing factors are analysed. The factors relating to the strength of nodes and leakage of liquidity that influences the liquidity demands of real-time settlements are studied from the perspective of both the system and members, using different simulation methods. The results show that strength will lead the member’s liquidity demand to increase but the strength distribution will lead the system’s liquidity demand to decrease, in cases with no leakage effect or unchanged leakage effect. The liquidity demand of the entire system is positive compared to the amount of leakage effect but uncorrelated to the distribution of the leakage effect among members, if the effect of strength distribution is unchanged. If the effects of strength, strength distribution and leakage are changed together, the latter is the dominant factor that influences the liquidity demand of both system and members. The above findings are useful for the management and supervision of short-term liquidity demand in complex financial systems, and for liquidity risk management and liquidity rescue policymaking.

One of the main issues of operators today is to be able not only to store and manage the huge amount of data generated by the applications and customer contact points, but also to give value to these data. But this implies using tools for storing the data, to manage it, look at it, understand it, exploit it, generate actions such as marketing campaigns. It is therefore obvious that using one tool for each of these functions will discuss here the technical issues involved and show how we turned them into an easy-to-use solution for business users.

Opis:
In the last decade, the oil industry has transitioned from primarily drilling vertical wells to a majority of extended reach complex horizontal wells with help of geosteering techniques for better reservoir and production efficiencies. The overall objective of geosteering and well placement has helped to maximize reservoir contact by the keeping well trajectory in the pay zone with the help of quality real-time data, especially in these uncertain times of pandemic due to COVID-19. This paper illustrates the immense impact of real-time data feeds (special logging tools/images) at operation centers with the full remote expert support of multidisciplinary teams. The proper data communication mechanism is also helpful to share the information across asset teams in a timely manner to drill complex wells remotely. To achieve the desired geosteering objectives, experts monitor and evaluate the real-time data in a landing well accurately in the pay horizon by designing the well path which considers geological variables like (reservoir architecture, permeability and porosity distribution, and fluid contacts) which further helps update the reservoir models in real-time based on the latest subsurface information for better reservoir management and timely decision making.

Opis:
The popularity of TCP/IP has resulted in an increase in usage of best-effort networks for real-time communication. Much effort has been spent to ensure quality of service for soft real-time traffic over IP networks. The Internet Engineering Task Force has proposed some architecture components, such as Active Queue Management (AQM). The paper investigates the influence of the weighted moving average on packet waiting time reduction for an AQM mechanism: the RED algorithm. The proposed method for computing the average queue length is based on a difference equation (a recursive equation). Depending on a particular optimality criterion, proper parameters of the modified weighted moving average function can be chosen. This change will allow reducing the number of violations of timing constraints and better use of this mechanism for soft real-time transmissions. The optimization problem is solved through simulations performed in OMNeT++ and later verified experimentally on a Linux implementation.

Opis:
The healthcare system today faces numerous challenges due to lack of visibility of resources and low utilisation, excessive rental as well as purchase of medical equipment. The article attempts to identify the possibilities of implementing a system of identification and location of assets in healthcare system institutions. This research presents market analysis in the context of available technological solutions. The implementation of real-time location system (RTLS) would enable not only tracking of equipment and inventory in medical facilities, but also increase visibility of inventory and manage the entire supply chain. Presentation of the proposed solution made it possible to assess costs, potential savings and the implementation process. This article is a starting point for a discussion on the cost-effectiveness of using RTLS in the healthcare system.

In this paper we propose estimation procedure in which traffic flows resulting from rerouting model are matched with traffic flows observed during unexpected events. We show practical value of observing a entire cut-set of the transportation network and propose theoretical closed-form formulation of estimation problem for the rerouting model. We apply proposed framework on field-data from Warsaw bridges to observe rerouting phenomena. Most importantly we observed that: a) around 20% of affected traffic flow reroutes, b) rerouting flows are increasing in time, c) drivers show strategic capabilities, d) and maximize their utility while rerouting. All of the which were hypothesized in Information Comply Model (Kucharski et. al., 2014) and are now supported with field observations.

Opis:
A state-of-the-art monitoring global navigation satellite system (GNSS) system has been originally designed and developed for various positioning and atmosphere-sensing purposes by the authors and updated to fulfil the challenging requirements for monitoring of ionospheric perturbations. The paper discusses various scientific and technically challenging issues, such as the requirement for an autonomous operating ground GNSS station and how this can be fulfilled. Basic algorithms for monitoring of local ionospheric perturbations with GNSS receivers are described. The algorithms require that inter-frequency hardware biases be known. Although the satellite transmitter biases can be obtain from the IGS services, the user takes responsibility for the estimation of frequency dependent receiver hardware biases and for the control of their variations. The instrumental signal delays are important for timing applications and GNSS monitoring of the ionosphere and are also required for recovering of the integer carrier-phase ambiguities. The paper presents an algorithm for calibration of inter-frequency biases of global positioning system (GPS) receivers and validates the first set of results.

Opis:
The GOOSE (GNSS Receiver with open software interface) Software-Defined Receiver has been developed at the Fraunhofer Institute for Integrated Circuits (IIS) in Nürnberg, Germany. The main motivation for the development of this platform was to control the receiver at all stages, from digital signal processing to the PVT domain, and to enable controlled feedback to the hardware. Besides having access to all raw data including correlation values, the GOOSE receiver also enables for example tight- or ultra-tight integration with an inertial navigation system or other dead reckoning systems, as these kinds of architectures require access to the acquisition and tracking loops. In this paper, the tracking performance of the GOOSE platform was evaluated and compared to a reference receiver (Septentrio PolaRx5S). Several long data sessions were recorded on a “zero baseline” in which both receivers used the same precise geodetic antenna that was also developed at Fraunhofer IIS. The measurements were performed in a harsh environment (obstructions, multipath, possible interferences), as well as on a site with an unobstructed sky view. Quality and performance analyses were performed using raw measurements (in the domain of primary observables) of three civil GPS signals: L1CA, L2CM, and L5. The data were processed using the “zeroEdit” module of the TUB-NavSolutions academic software for education and research. The quality of the raw observables and tracking performance were described by the following parameters: number of cycle slips detected, number of un-correctable cycle slips, number of loss of locks of the signals, number of single epoch data gaps, and the length of carrier phase arcs. The presentation is illustrated with some numerical examples.

Research background: With increasing evidence of cognitive technologies progressively integrating themselves at all levels of the manufacturing enterprises, there is an instrumental need for comprehending how cognitive manufacturing systems can provide increased value and precision in complex operational processes. Purpose of the article: In this research, prior findings were cumulated proving that cognitive manufacturing integrates artificial intelligence-based decision-making algorithms, real-time big data analytics, sustainable industrial value creation, and digitized mass production. Methods: Throughout April and June 2022, by employing Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines, a quantitative literature review of ProQuest, Scopus, and the Web of Science databases was performed, with search terms including "cognitive Industrial Internet of Things", "cognitive automation", "cognitive manufacturing systems", "cognitively-enhanced machine", "cognitive technology-driven automation", "cognitive computing technologies", and "cognitive technologies". The Systematic Review Data Repository (SRDR) was leveraged, a software program for the collecting, processing, and analysis of data for our research. The quality of the selected scholarly sources was evaluated by harnessing the Mixed Method Appraisal Tool (MMAT). AMSTAR (Assessing the Methodological Quality of Systematic Reviews) deployed artificial intelligence and intelligent workflows, and Dedoose was used for mixed methods research. VOSviewer layout algorithms and Dimensions bibliometric mapping served as data visualization tools. Findings & value added: Cognitive manufacturing systems is developed on sustainable product lifecycle management, Internet of Things-based real-time production logistics, and deep learning-assisted smart process planning, optimizing value creation capabilities and artificial intelligence-based decision-making algorithms. Subsequent interest should be oriented to how predictive maintenance can assist in cognitive manufacturing by use of artificial intelligence-based decision-making algorithms, real-time big data analytics, sustainable industrial value creation, and digitized mass production.

Celem niniejszego artykułu jest wykazanie, w jaki sposób zastosowanie paradygmatu narracyjnego może być wykorzystane w inicjowaniu zmiany, jaka dokonuje się w relacjach między związkami zawodowymi a pracodawcą podczas rozwiązywania sporów zbiorowych z zastosowaniem procedury mediacyjnej. Z tej perspektywy zmiana organizacyjna związana jest z dekonstrukcją funkcjonującej narracji i konstrukcji nowej, lepiej spełniającej funkcje adaptacyjne. Podejście zaprezentowane w niniejszym artykule wywodzi się z procesualnego ujęcia organizacji oraz nurtu konstruktywizmu społecznego.
Time not only develops or impoverishes relationships and people, creates values and measures an employee’s share in their creation, but is the reason for and the dimension of the change as well. This article discusses the background behind the increased interest in temporal awareness on the part of change managers. It suggests twenty–six typological criteria that can serve to describe such conclusions and concludes with a definition.

Enterprises using cranes, HDS platforms, other handling equipment, or pressure equipment in their activities are subject to registration with the Office of Technical Inspection (UDT), which is obliged to conduct inspection activities on them. Inspections of technical devices are aimed at checking their technical condition. Approximately 1.3 million technical devices are currently subject to UDT supervision in Poland. Annually, UDT inspectors carry out over 1 million tests of technical devices, and the activities carried out by UDT translate into a constant reduction in the accident rate. All this takes place in conditions that require continuous work planning and scheduling. This article aims to present and discuss the use of open-source solutions for planning the work of teams carrying out inspection activities, along with the concept of their use.
