Flexible Production System

Industry 4.0 offers a new opportunity to realize flexible and efficient production. Through modelling the production systems in Industry 4.0, potential delays, interrupts and defaults could be prognosticated and treated on time. Consequently, the productivity and efficiency of production systems can be enhanced. Flexibility has a far-reaching impact on the design of production systems in Industry 4.0 and is still a challenge in the modelling yet. In order to achieve realistic results, dependence must also be taken into account. In this article, a concept of flexible production system in Industry 4.0 is first presented. Then, two models of extended coloured stochastic Petri nets are built and simulated using a software REALIST to investigate the features of flexibility and dependence in production systems in Industry 4.0. As a result, the productivity and availability of production systems are analysed and discussed in the end.

The article describes the use of flexible project management approaches during the formation of virtual enterprises. The article is devoted to the consideration of modern approaches to the definition of the concept of "virtual enterprise with a flexible production system." The study used several methods: generalization, systematization, formalization, logical, formal methods, as well as comparative analysis methods to study modern approaches of the definition of the studied concept. The tasks considered in the article are theoretical. The economic content of the concept of “virtual enterprise and flexible production system” is disclosed. The article presents the current economic content of the concept of “Flexible production system” based on a review of modern approaches to the definition of this concept, and also highlights key indicators for the implementation of a flexible production system. The basic concepts, ideas, methods of creating virtual enterprises are formulated. A new technology for the implementation of management tasks based on system design, control theory, business process and intelligent modeling were proposed [2,3].

Abstract: The dynamics of the interaction between different levels in production system is the study of many research groups to seek a better understanding of the complex nature of such systems to propose an effective and efficiency from rational use of available resources and required inputs. Demand for products increasingly customized by a dynamic and competitive market has reduced considerably the life cycle of such products and flexibility of production processes has become essential for companies. Flexibility is not only one attribute, but a set of attributes that provides the flexibility for production systems. The interactions between the flexible sub-systems are sources of waste and rework, causing high costs in the production process. In this sense, the concept of Lean Manufacturing has promoted a restructuring of some processes of the MES (Manufacturing Execution Systems), responsible for managing the activities of production, integrate data from the ERP (Enterprise Resource Planning) and synchronize production tasks the flow of materials, making them oriented by the demand. One other important aspect in the industrial context is the new future vision promoted by Industry 4.0 paradigm that is envisioned a complete decentralization of control of the production system by autonomous and intelligent devices interconnected by a communication system, that contribute to the global goals of the enterprise. The ANSI/ISA S95 presents a conceptual model that may contribute to the implementation of the industry 4.0 concept. The objective of this study is to present a proposal for modeling of objects in level 3 of the S95 standard using interpreted Petri nets.

The intensive development of information technologies and software and hardware of control systems creates conditions for active processes of digitalization of the industry. One of the relevant areas of digitalization in production is the development and implementation of flexible production systems that expand the functionality of production lines and increase the efficiency of the production process. This paper deals with the development of a transport management system of a flexible production system. A solution is proposed that includes a block diagram of the system, hardware and functional logic.

Abstract With the rise of the Industry 4.0 and the digitization increase in the field of design of the automated devices and systems, raises the requirements to digitize all stages of the design processes, including Virtual Commissioning. This technology allows to verify the functionality of the device and/or systems, generate OLP programs for robots and test the functionality of the PLC code on the virtual model. The article presents research into the possibility of implementing a robotic cell into a real flexible production system in the Laboratory in order to eliminate defective products after an automatic control through the Quality-handling station. This technology was verified on the basis of a methodology through a virtual system model and a virtual control system in the Software-in-Loop using the Siemens Tecnomatix Process Simulate software.

For the development of modern complex production processes in Industry 4.0, it is appropriate to effectively use advanced mathematical models based on Petri nets. Due to their versatility in modeling discrete-event systems, Petri nets are an important support in creating new platforms for digitized production systems. The main aim of the proposed article is to design a new software tool for modeling and control of discrete-event and hybrid systems using Arduino and similar microcontrollers. To accomplish these tasks, a new tool called PN2ARDUINO based on Petri nets is proposed able to communicate with the microcontroller. Communication with the microcontroller is based on the modified Firmata protocol hence, the control algorithm can be implemented on all microcontrollers that support this type of protocol. The developed software tool was successfully verified in control of laboratory systems. In addition, it can be used for education and research purposes as it offers a graphical environment for designing control algorithms for hybrid and mainly discrete-event systems. The proposed software tool can improve education and practice in cyber-physical systems (Industry 4.0).
