Opis:
According to the Theory of Constraints by Goldratt system bottlenecks are key to improving productivity and profitability of the entire production system. An important issue in the practical application of this theory is to identify bottlenecks in the system. The aim of this paper is to develop practical steps to identify bottlenecks in the production system characterised by a homogeneous flow. The paper includes a case study which shows six steps that allowing to specify not only the first bottleneck of the system but to develop a comprehensive plan for removing bottlenecks.

Opis:
This paper is about the integration of discontinuous milling operations into the continuous flow production line of branched sheet metal profiles in an integral design. A major challenge is the non-existing possibility to clamp the work piece due to its constant feed. The machining on the fly itself is only possible through synchronizing the movement of the machine tools axes with the continuous feed of the sheet metal profile.

Logistyka wewnątrzzakładowa jest często pomijana przy optymalizacji procesów przedsiębiorstwa. Menadżerowie zakładów produkcyjnych niejednokrotnie zakładają, że oczekiwane efekty mogą uzyskać wyłącznie poprzez doskonalenie procesów produkcyjnych i skracanie czasów cykli poszczególnych operatorów. 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.
Optimizing processes in the company, especially in factories, is an important part of corporate strategy. With help of a special software, simulation allows to check the usefulness and cost-effectiveness of suggested solutions. Undeniable advantage is low cost of verification. Simulation is invaluable opportunity which was decided to present in article based on a real example.

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.

In the paper an improvement heuristic is proposed for permutation flow-shop problem based on the idea of evolutionary algorithm. The approach employs constructive heuristic that gives a good initial solution. GA-based improvement heuristic is applied in conjunction with three well-known constructive heuristics, namely CDS, Gupta’s algorithm and Palmer’s Slope Index. The approach is tested on benchmark set of 10 problems range from 4 to 25 jobs and 4 to 30 machines. The results are also compared to the best-known lower-bound solutions.

Opis:
Requirements for quality and the full traceability of products supplied in some industries, such as eg. the food industry, the pharmaceutical industry as well as automotive industry, result that the implementation of production flow control systems (FCS) becomes a very important element in the functioning of enterprises. Production flow control systems are used generally for recording production data at different stages of industrial processes (in this respect, they fulfill the function of traceability systems), but also provide blocking of incorrectly processed identifiable components during the earlier stages of the production. The information provided by traceability can be the basis for the functioning of integrated information systems. Production flow control systems ensure the recording of important information from the point of view of customer that allows the capture of defective products, analysis of the causes of these defects, and defense against potential complaint or even a significant reduction in the number of complaints. Applied are dedicated or universal solutions, adaptable to a variety of configuration lines / production cells. Dedicated solutions (for a specific production line) are basically always developed from scratch, taking into account the specificity of the product flow. Then the structure of the data in the PLC has to be adjusted, as well as the structure of the database and the database queries. Dedicated systems have the advantage that their action is fast, whereas the drawback is a longer start-up time and modification / expansion of functionality. On the other hand, universal solutions allow to configure the number of workstations and their type (controlled by a PLC or PC), their network addresses, as well as the types of products allowed there without changing the software. The advantage of universal solutions is that additional production workstations can be added very fast to the system, while the disadvantage may be longer lasting query the database and exchange information with the PLC. The concept of an universal system must be well thought and considered have to be different configuration cases of the material flow. Poorly thought-out concept takes revenge on the creator by the necessity of profound changes in the structure of the data and the application code. The purpose of this article is to present the advantages and disadvantages of dedicated and universal TCS / FCS systems.

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.
