Opis:
Production problems have a significant impact on the on-time delivery of orders, resulting in deviations from planned scenarios. Therefore, it is crucial to predict interruptions during scheduling and to find optimal production sequencing solutions. This paper introduces a selflearning framework that integrates association rules and optimisation techniques to develop a scheduling algorithm capable of learning from past production experiences and anticipating future problems. Association rules identify factors that hinder the production process, while optimisation techniques use mathematical models to optimise the sequence of tasks and minimise execution time. In addition, association rules establish correlations between production parameters and success rates, allowing corrective factors for production quantity to be calculated based on confidence values and success rates. The proposed solution demonstrates robustness and flexibility, providing efficient solutions for Flow-Shop and Job-Shop scheduling problems with reduced calculation times. The article includes two Flow-Shop and Job-Shop examples where the framework is applied.

Opis:
This paper presents the concept and methodology for the designing of a “tree-shaped” production line. The concept is a result of the search for production unit organization that meets the Lean Production assumptions, i.e. focusing on lead time (throughput time) shortening with simultaneous ability of use in conditions of varied product range. The varied product range characterized by lower technological-organizational similarity when compared to “Ushaped” units typical for Lean Production. The paper presents an algorithm for the designing of a “tree-shaped” production line and examples of its application. The designed unit underwent evaluation according to the criteria preferred by Lean Manufacturing experts. The designed production unit achieved results confirming the effectiveness of the proposed concept for the analysed sets of input data on the product range and production capacities.

Opis:
The globalization process and the marginalization of Europe in world production prompted the German economy to implement the Industry 4.0 concept called the fourth industrial revolution. As a part of the proposed concept, a close connection of physical objects with the information network should be made. Enterprises will connect by intelligent resources communicating through the modern Internet of Things technologies, big data, and cloud computing. Therefore modern enterprises have a new further challenge which means a need to build and cooperate within cyber-physical systems. The aim of the article is to present key challenges for Polish small and medium-sized manufacturing enterprises oriented to the cooperation within the Industry 4.0 concept. Furthermore, the results of surveys conducted on a selected group of Polish production companies in the metal sector are shown. These results present the condition of Polish enterprises, their concerns and expectations regarding the implementation of the Industry 4.0 concept. The paper contains also the new idea to create the Cyber Industry Network (CIN) which means a kind of the on-line available platform for exchanging production capacity of small and medium enterprises and allows for the efficient combining of free resources to realize joint production projects.

Opis:
Flow cytometry is commonly used in sugar-beet breeding and seed production for ploidy estimation. By means of this method individual plants as well as plant populations can be analysed. An interpretation of histograms obtained from anisoploid populations, however, causes some problems to the breeder. Bulks of diploid, triploid and tetraploid sugar-beet plants in different proportion and ploidy combinations (2x + 3x, 2x + 4x, and 3x + 4x) were tested in order to determine the relation between the actual share of the components of different ploidy levels in tested populations and that calculated on the basis of flow cytometry. In this way agraph for estimation of the share of different ploidy components was obtained. Repeatability of the results proves the usefulness of flow cytometric analysis of anisoploid plant populations in breeding and seed production of polyploid crops.

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:
Determination of ploidy level is a common practice in sugar-beet breeding and seed production. Lately many laboratories have replaced microscopic chromosome counting by flow cytometric estimation of the nuclear DNA content. The possibility of direct estimation of cytological composition in anisoploid populations instead of individual plant analyses was investigated. Diploid, triploid and tetraploid sugar-beet lines as well as their mixtures were tested. The results obtained show that the suggested method is fast, simple and, after a proper transformation of the computer values, could be applied in breeding and seed production of polyploid crops. Precise estimation of contamination by small admixture of seeds or plants of undesirable ploidy, however, requires individual plant rather than population analyses.

Opis:
Reservoir condensate blockage in the reservoir and in particular in the close vicinity of the wellbore may result in significant loss of well deliverability for medium to tight gas reservoirs. The dynamics of fluid flow in these types of reservoirs are investigated by way of analytical description and by numerical simulation of radial two phase flow behavior. The analytical model is based on a single phase semi steady-state solution, being revised for two phase flow of gas and condensate oil. As the liquid is dropping out of the gas, a saturation distribution of immovable oil is seen to develop radially in the reservoir with time. Condensed oil not being part of this saturation distribution is produced to the surface. The numerical model is a cylindrical, single well, fine gridded, simulation model run on the Eclipse E300 compositional simulator. The base case study comprises a rich gas condensate fluid (GOR ~ 1000 Sm3/Sm3), an initial gas-in-place volume of 750 MSm3, and reservoir permeability of 10 mD. A gas flow rate of 0.5 MSm3/day is leading to a production period of about 4 years. A comparative study is performed by varying parameters such as pressure development, development of bank of immovable oil both radially and as function of time, condensate blockage effects, and gas and condensate oil production and onset of reduced well deliverability. Sensitivity analysis are performed by studying variation in the productivity index, non-Darcy and mechanical skin, and sensitivities related to permeability. It has been confirmed in this study that condensate blockage has a direct and negative impact on well deliverability, where both the plateau period and the bottom hole pressure are reduced. We also show that the analytical model compares well with the numerical models and that many features describing gas-condensate banking and well deliverability are adequately described in the model. The analytical model also offers insight into the process of reservoir liquid storage in gas condensate reservoirs.

Inwestując kapitał w drogie oprzyrządowanie oraz zapasy materiałów uważają, że w ten sposób uzyskają lepsze wyniki zakładu i oczekiwane cele. Warto zastanowić się nad procesem wspierającym produkcje jakim jest logistyka – dobrze zorganizowana i ustandaryzowana staje się cennym filarem przedsiębiorstwa.
