Opis:
Recent traceability requirements create necessity of organization of the food production process in the completely new way. This way of production organization is typical rather for large industry, than for traditional way of work at the rural areas. This fact generates tensions as well as resistance of the farmers, especially farmers working in traditional way. This paper presents new ideas of industrial application of automation standards and methodologies for reliable, robust and user-friendly food traceability system. Due to the high level of automation and application of industrial IT solutions together with multimodal data transmission, presented traceability system can be implemented in traditional food production farms and operated intuitively by personnel without specialized training. As a result application of presented system will signifi-cantly reduce tensions and resistance connected with implementation of new technologies in tradi-tional food production farms.

The article presents the results of research on the use of measuring devices based on RFID tags and graphic tags to track the increase in production. The conducted research experiments were made in a real production company, which is characterized by an average degree of digitization of its business processes and significantly uses the human factor in production. The conducted research allowed us to show the usefulness of measurement methods in tracking business processes, and to analyze the method of obtaining production data to achieve the traceability of manufactured components. The study also presents selected examples of IT systems in solving traceability problems (traceability and traceability of production).

Opis:
Aim: Blockchain technology (BCT) is a relatively new technological development, promising strong gains in the areas of product traceability and visibility, end-to-end coordination (E2E), governance, and efficiency of supply chains. The aim of this study is to gain a better understanding of the impact of BCT on these performance measures. Design / Research methods: Hypotheses were tested with survey data from 119 supply chain professionals from Northern American SMEs. Conclusions / findings: The results confirm the positive impacts of BCT on all performance measures. E2E coordination is the integration of information, goods, and money within an organisation or supply chain. E2E coordination appeared to benefit from the use of BCT, enabling information sharing in a safe way. The findings suggest that BCT use fosters E2E coordination, which in its turn also positively affects financial performance. Originality / value of the article: Despite the increasing interest in and use of, BCT, there is little empirical evidence for the effect on supply chain performance. Many studies are anecdotal and lack empirical evidence. Implications of the research (if applicable): Companies should acknowledge the impact of BCT use on the various supply chain performance measures. Implementing and using BCT is likely to foster improvement in a wide range of performance indicators.   Limitations of the research  (if applicable): Companies use different types, versions, varieties, and forks of blockchain, all having their own strong and weak points. Future studies could investigate and include the nuances within different forks of BCT.

Opis:
Capacitive leakage and adjacent interference are the main influence sources of the measuring error in the traditional series step-up method. To solve the two problems, a new algorithm was proposed in this study based on a three-ports network. Considering the two influences, it has been proved that response of this three-ports network still has characteristics of linear superposition with this new algorithm. In this threeport network, the auxiliary series voltage transformers use a two-stage structure that can further decrease measurement uncertainty. The measurement uncertainty of this proposed method at 500/√3 kV is 6.8 ppm for ratio error and 7 μrad for phase displacement ( k = 2). This new method has also been verified by comparing its results with measurement results of the PTB in Germany over the same 110/√3 kV standard voltage transformer. According to test results, the error between the two methods was less than 2.7 ppm for ratio error and 2.9 μrad for phase displacement.

As a second main result, we present classes of graphs ₁,...,₈ such that every sufficiently large connected claw-free graph satisfying degree condition σ₆(k) > n + 19 (or, as a corollary, δ(G) > (n+19)/6) either belongs to $⋃ ⁸_{i=1} _i$ or is traceable.

A well-known theorem by Chvátal-Erdőos [A note on Hamilton circuits, Discrete Math. 2 (1972) 111–135] states that if the independence number of a graph G is at most its connectivity plus one, then G is traceable. In this article, we show that every 2-connected claw-free graph with independence number α(G) ≤ 6 is traceable or belongs to two exceptional families of well-defined graphs. As a corollary, we also show that every 2-connected claw-free graph with independence number α(G) ≤ 5 is traceable.

Opis:
The objective of the paper is to analyse traceability issues in real-life gas flow measurements in complex distribution systems. The initial aim is to provide complete and traceable measurement results and calibration certificates of gas-flow meters, which correspond to specific installation conditions. Extensive work has been done to enable a more credible decision on how to deal in particular situations with the measurement uncertainty which is always subject of a flow meter’s calibration as a quantitative parameter value obtained in laboratory, and with the qualitative statement about the error of an outdoor meter. The laboratory simulation of a complex, real-life distributed system has been designed to achieve the initial aim. As an extension of standardized procedures that refer to the laboratory conditions, the proposed methods introduce additional “installation-specific” error sources. These sources could be either corrected (if identified) or considered as an additional “installation-specific” uncertainty contribution otherwise. The analysis and the results of the experimental work will contribute to more precise and accurate measurement results, thus assuring proper measurements with a known/estimated uncertainty for a specific gas flow installation. Also, the analysis will improve the existing normative documents by here presented findings, as well as fair trade in one of the most important and growing energy consumption areas regarding the legal metrology aspects. These facts will enable comparing the entire quantity of gas at the input of a complex distributed system with the cumulative sum of all individual gas meters in a specific installation.

Opis:
Standardization has contributed significantly to comparable analysis methods for power quality parameters. However, in order to have undisputable results, the measurement values themselves should also be comparable. This can only be achieved by traceability to international measurement standards. For this reason, at VSL, the Dutch national metrology institute, a fully traceable reference setup was developed for calibration of power quality analyzers. In this paper, we show the calibration results of the critical components of the reference setup, we demonstrate its applicability by test measurements on the public low-voltage supply system for specific parameters, and show its ability to simulate and generate events that can be detected and analyzed by both the equipment under test and the reference setup.

Opis:
Traceability in solids is difficult to ensure, as in piece goods. The batch as a whole will change constantly mixing processes by their composition and size. For traceability not only an appropriate identification system but also an approach to batch management is required. The systems supporting traceability provides a sophisticated batch concept and a batch coding persecution of lots within a single company, between customer-supplier dyads, as well as along the entire distribution chain. The introduction of a traceability systems is connected with technical and organizational effort. In the event of an inter-company implementation further agreements with suppliers and/or customers are required. Is a traceability system implemented, but it offers flexible opportunities to share quality information and thus to improve quality across the entire grain chain.
Rozporządzenie 178/2002 UE nakłada na wszystkich uczestników łańcucha żywnościowego obowiązek identyfikowalności (traceability), czyli śledzenia pochodzenia produktu. Jest ono trudniejsze w przypadku towarów sypkich niż towarów jednostkowych. Poszczególne partie podlegają procesom mieszania się, z punktu widzenia składu oraz wielkości. W celu zapewnienia identyfikowalności wymagany jest nie tylko właściwy system identyfikacji, ale również zarządzanie partiami. Systemy wspierające identyfikowalność powinny być przystosowane do odpowiedniej systematyki i sposobu kodowania partii towarów wewnątrz przedsiębiorstwa, jak i pomiędzy poszczególnymi ogniwami łańcucha dystrybucji. Wdrożenie systemów wspierających monitorowanie pochodzenia produktów wiąże się z nakładami technologicznymi i organizacyjnymi. W przypadku implementacji międzyorganizacyjnej niezbędne są porozumienia między dostawcami i/lub dostawcami. Wdrożenie odpowiedniego systemu identyfikowalności pozwala na elastyczną wymianę informacji dotyczących jakości, a tym samym na poprawę jakości w całym łańcuchu dostaw.

Assigning transported material with a supplementary information is becoming relevant for the needs of improving the efficiency of industrial processes. In the mining industry annotating the mined ore could bring benefits due to expected decrease of the processing energy consumption and increase of productivity. DISIRE project was focused on the implementation of e-pellets for various raw material processing and transportation processes. The paper presents laboratory tests of altern ative RFID equipment for annotating ore with marked tags. Several aspects of tags traceability were investigated for the needs of the industrial tests that were eventually done in the underground mine environment. The laboratory tests results were compared with the similar tests described in the literature, that were done in the different conditions.

Opis:
Background: Socio-cyber-physical systems (SCPSs) are a type of cyber-physical systems with social concerns. Many SCPSs, such as smart homes, must be able to adapt to reach an optimal symbiosis with users and their contexts. The Systems Modeling Language (SysML) is frequently used to specify ordinary CPSs, whereas goal modeling is a requirements engineering approach used to describe and reason about social concerns. Objective: This paper aims to assess existing modeling techniques that support adaptation in SCPSs, and in particular those that integrate SysML with goal modeling. Method: A systematic literature review presents the main contributions of 52 English articles selected from five databases that use both SysML and goal models (17 techniques), SysML models only (11 techniques), or goal models only (8 techniques) for analysis and self-adaptation. Result: Existing techniques have provided increasingly better modeling support for adaptation in a SCPS context, but overall analysis support remains weak. The techniques that combine SysML and goal modeling offer interesting benefits by tracing goals to SysML (requirements) diagrams and influencing the generation of predefined adaptation strategies for expected contexts, but few target adaptation explicitly and most still suffer from a partial coverage of important goal modeling concepts and of traceability management issues.

Opis:
Requirements regarding the quality and full traceability of delivered products in some industrial sectors, such as the food, pharmaceutical and automotive industries, where the life and health of the end user depends on the quality of the product, cause production flow control systems (PFC) to become an important element of the functioning of production enterprises. PFC systems are IT systems that are generally used for recording production data (in a database) at various stages of industrial processes, mainly from PLC controllers (in this respect they perform the function of traceability systems, that enable tracking products), but also provide blocking of identifiable products, which were incorrectly processed during earlier stages of production or follow wrong technology sequence. The desirable feature of such systems is their flexibility, which is characterised by their scalability and configurability. Configurability is the ability to include different processes into the PFC system in a relatively short time. The concept of a configurable system must be well considered and different material flow cases must be taken into account to avoid future dramatic changes in the IT system. Scalability is the ability to include more and more processes under control of the PFC system without the significant impact on its effectiveness. The PFC systems use computer networks to process production data, so the scalability of PFC systems depends on their modular architecture in the network. The article discusses basic features and possible PFC architectures, as well as two examples of configurable PFC systems along with their analysis and assessment. The described systems are the result of projects in which the author of this article participated, the aim of which was to develop and launch a flexible PFC system that meets the basic industrial requirements from the area of discrete manufacturing.

Opis:
The focus of this review paper is to present the state of the art regarding RFID implementations in wood supply chains, covering the tree marking stage till the transportation to the final processor. The easier than ever collection of data using sensors and the emerging ability to exchange information in the context of the Internet of Things (IoT) form a very promising new environment for the optimization of wood supply chains. Driven by currently enhanced, ability to store different layers of information per merchantable unit (tree assortments at final or semi-final form or containers of woody biomass), RFID applications can provide valuable solutions and revolutionize wood supply chains by warranting traceability, combating illegal logging, minimizing waste and offering detailed information of the wood products properties, among other benefits that are presented in the text. The benefits can be identified at the ecological, social and economic levels, addressing the sustainability concerns of modern societies. To make use of this huge potential, a continuous flow and fusion of information at all supply chain stages must be taken for granted, as well as the close cooperation among stakeholders.

Opis:
Billions of people in the world are at risk of getting unsafe food. There is an urgent need to improve efficiency and effectiveness of food supply chains. The global population is expected to reach at least 9 billion by the year 2050, requiring up to 70% more food than nowadays and demanding food production and distribution to become much more sustainable. Today, food safety is a worldwide concern due to a number of food safety scandals. As supply chains become more globalized and complex, the ability to track and trace products from fork to farm becomes more difficult but remains equally important. Good traceability may minimize the production and distribution of unsafe or poor quality products. It allows targeting the product affected by a food safety problem, minimizing disruption to trade and any potential public health risks. The objective of this paper is therefore to conduct a comprehensive analysis of traceability methods and technologies in food supply chains.
