This paper presents an introduction of two simulation environments for the purpose of optimizing production line. The time in which we are implementing the concept of Industry 4.0, a part of which is based on automated and robotic production systems, we want to pre-check financial and production efficiency of the proposed new updated concept of our existing production line. A comparison of two different programming environments for discrete systems simulation will be presented in this paper on the applied industrial example. Simulation model enables calculation of machine utilization, throughput time, number of finished products and minimum needed workers (MNW). If we want to justify the use of simulation environments for the purpose of optimizing production, we must firstly show the real world example as in presented paper. The result will justify the redesign of the existing production line and justify the use of simulation software tools for carrying out preliminary tests to create new more productive production line, which is designed on concept of Industry 4.0.

Continual improvement of production process consists of small incremental improvements combined with breakthrough improvement steps. These improvements are usually achieved through the improvement of the organization, processes and people skills using improvement concepts like Lean management. Sometimes, usually for breakthrough improvements, significant financial investments in technology are needed. On the other hand, improving of organization, processes and people skills usually do not require significant financial investments. Therefore, for industrial enterprises, it would be the most valuable to have a procedure for the management of the continual improvement process. The procedure that identifies and focuses on the most important processes or part of processes and selects the improvement action which will have the best effect on key performance indicators (KPIs) of the production process. In this research, an integrative procedure for management of production and service improvement process is experimentally tested on the real assembly line in the Laboratory at FESB, University of Split. The focus of this paper is on the innovative multicriteria decision making support system for prioritization of proposed improvement processes, based on the HUMANT algorithm. The result is that one proposed improvement process is selected as the most effective solution, according to pre-defined KPIs. [ABSTRACT FROM AUTHOR]

The paper related to the problem of creation the new technology of multi-agent control for industrial automation – creating the automated system, realising multi-recipes production of a large number of types with logical processing of contradictions. This required to find a proper software decisions for distant access, reprogramming and monitoring the production line even during it's functioning. The created system of logical processing, basing on brunching time logics, and parallel software, controlling production line as well as the imitation modelling, are a new way for intelligent industry 4.0.

This paper describes some results of authors' research in machine vision, as a key technology, essential in connecting the manufacturing processes with the digital twin of the manufacturing architecture. The focus is on designing a system that uses machine vision in combination with deep learning algorithms. The result is a human-like vision system for realtime analysis and interpretation of all video streams of cameras to continuously detect and count the various products on the production line. All detected features and counting information are available in real-time by augmenting on a video screen and streamed to the cloud where they can be easily processed and stored.

The paper proposes an optimizing algorithm based on a virtual model of a processing architecture. To illustrate this algorithm we have chosen a beverage production line, a diffused processing architecture using productivity as the main performance indicator. The material flow management of this beverage can production line will be based on its virtual model in order to identify and eliminate material flow concentrators and increase productivity. Simulation will be used to diagnose the initial performance of the system structural elements as well as to validate the optimized system performances after eliminating the bottlenecks. The algorithm could easily be adapted to any manufacturing or processing architecture based on discrete material flow, where the circulating entities (e.g. parts) are distinct and countable.

The paper focuses on mutual comparison of currently most common methods for time standardization. For comparison of selected methods an experimental research in conditions of automotive assembly production was performed. Compared methods were direct measurement according to REFA methodology and two predetermined time systems MTM-1 and BasicMOST. Mutual comparison of results obtained by means of those 3 methods was performed. The experiment was performed on 21 assembly workplaces where time span of analyzed operations oscillated between 4 to 29 seconds. The main goal of the research was to demonstrate reliability, mutual accuracy and deviations of selected methods. A hypothesis needed for verification was stated, that individual methods should have maximal accuracy deviation ± 10%. Findings about time demands for performing the analysis according to selected method was a partial goal of our research. [ABSTRACT FROM AUTHOR]

The main purpose of this paper is to focus on one of the more comprehensive current initiatives, those building on lean practices and principles, in the context of assembly lines processes, in order to build a deeper understanding how lean instruments can improve materials flows based on the interdependence of lean techniques. To deal with the question how to improve the materials flow in a lean environment, we have adopted a twofold approach in this article based on an analysis of existing literature on the subject and the observation of practices in the workplace. The observation of workplace practices make possible to compare different solutions advance by advocates of the lean approach with the facts. The views expressed in this regard will be based on the observation of companies from car assembly sector, which have implemented lean logistic for over four years. [ABSTRACT FROM AUTHOR]

In the case of three-dimensional (3D) printing complex products or big assemblies must be minimize the manufacturing process cost. Taking this into account, some printing parameters must be optimised, such as 3D printing time, post-processing time and material consumption. In this paper, a methodology regarding of design for additive technologies (DFAdT) and design for rapid prototyping/ rapid manufacturing assembly (DFA-RP/RM) is proposed, based mainly on separation of complex products in optimal subassemblies. A case study focused on a new concept of an electric vehicle (self-balancing scooter) is presented. The scaled prototype is manufactured using polyjet additive technology within the Industrial Innovative Technologies Laboratory, Department of Manufacturing Engineering from "Transilvania" University of Brasov, Romania.

Industrial robots are used especially in sectors where the human body is in danger or is working in extreme conditions. One of these sectors is the forges sector where the manipulating objects are hot, and the vibrations and noise are big. The cooling of gripper and robot is realized passively in the movement phase, when no hot work piece is manipulated. So, the trajectory of movement is important and also the optimum position of robot with respect to the application positions. The proposed paper is dealing with the subject of moving the base of robot with respect to the application points so that an objective function representing the accumulated heat during a cycle to be minimum. A multi-criteria optimization approach is the best solution in this case. [ABSTRACT FROM AUTHOR]

The implementation of the PCPPCS into value adding is a current strategy to align production processes to the forces of market. Globalisation, shallow diversification of manufacturing and cost-effectiveness enforce the harmonisation of sales-order flows with all relevant value- adding processes. This paper focuses on technical and organisational aspects of turbulence-drivers, which disrupt a planned sequence of production orders (po's) and thus, increase production costs. When implementing the PCPPCS into running processes of series and mass production, it is essential to localise and analyse the instabilities of the whole process. Therefore we describe our approach of process- segmentation and FMEA of relevant process-steps. [ABSTRACT FROM AUTHOR]
