Contemporary firms organize their activities in the form of extended enterprises. Extended enterprise is the concept that a company does not operate in isolation because its success is dependent upon a network of partner relationships established in the whole supply chain. These relationships are used for coordination of activities done by firms, e...

The workplace inclusion of individuals with cognitive disabilities, or neurodiversity, is a multifaceted and intricate phenomenon that necessitates a comprehensive understanding of the factors that either facilitate or hinder it. Tools that can aid in achieving this understanding are the fuzzy cognitive maps, graphical representations of the mental...

Remanufacturing processes are one of the key pillars of the so-called closed-cycle economy. Unfortunately, the design and organization of such processes pose a significant problem, due to, among other things, the high variability of the process as a consequence of both the degree of wear and tear and the quality of the remanufactured components. Th...

People with disabilities can be very valuable employees if their work is well organized and planned. However, because such employees have certain limits and additional rights, the organization and planning are more complex. This article aims to show how the employment of people with disabilities (PWDS) could influence the operation of a manufacturi...

Computer simulations are applied in enterprises for different purposes. They are used to support decision making at different levels of management. System Dynamics (SD) method is successfully used to model and simulate complex systems (including enterprises and manufacturing lines), but its applications are limited mostly to the policy and strategy...

In the last decade, a shift toward Sustainable Development (SD) in engineering has started in the educational and occupational framework. Therefore, the need to rethink the professional figures of an engineer has become a necessity. Unfortunately, neither a formal methodology to define a standard engineer achetype nor procedural methods to evaluate...

This article deals with compression of binary sequences with a given number of ones, which can also be considered as a list of indexes of a given length. The first part of the article shows that the entropy H of random n-element binary sequences with exactly k elements equal one satisfies the inequalities klog2(0.48·n/k)<H<klog2(2.72·n/k). Based on...

The emerging of the fourth industrial revolution, also known as Industry 4.0 (I4.0), from the advancement in several technologies is viewed not only to promote economic growth, but also to enable a greener future. The 2030 Agenda of the United Nations for sustainable development sets out clear goals for the industry to foster the economy, while pre...

In manufacturing enterprises implementing the idea of Industry 4.0, devices that generate data are increasingly used. Over time, huge data sets are created. These collections, known as Big Data, are very important to the company because they can contain valuable information. One of the goals of today’s enterprises is to discover this information an...

The work describes various problems that can arise in the planning, organization and operation of manufacturing processes. The consequences for the companies resulting from the problems are deliberated together with the proposed remedies. It is important to teach students what kind of problems they may face in their future work and how they can ana...

Engineers need to know a wide spectrum of modern techniques and tools to be able to apply them in their professional work. Modeling and simulation are examples of the activities that are commonly undertaken by modern engineers, especially in the context of Industry 4.0 concept. Therefore, it is important that in the process of engineers’ education...

People play a central role in intelligent manufacturing systems because of two reasons: their knowledge is indispensable to create and improve intelligent manufacturing systems; and their motivation is very important to identify and solve causes of the problems which may occur in order to prevent them in the future. Therefore, adequate learning met...

Industry of the future bases on people knowledge, creativeness and motivations. Although, the number of workers needed in factories of the future decreases, the requirements concerning employees skills have been increasing. The knowledge of employees determines the factory system quality and efficiency. The motivation of people determines continuou...

Companies have to meet clients' requirements with regard to product quality and delivery time. In order to survive and have possibilities to develop, companies should do it at minimal cost. The lean manufacturing implementation approach together with lean tools, such as value stream mapping (VSM), is an efficient way for waste identification and el...

Companies have to meet clients’ requirements and, at the same time, be cost effective to survive. In order to minimize costs, companies implement lean manufacturing concept and lean tools such as the value stream mapping (VSM) to identify and then eliminate waste. VSM allows a static analysis therefore the authors of this work propose integration o...

In the paper two kind of simulation methods, i.e. system dynamics simulation (SDS) and discrete event simulation (DES), are proposed to simulate orders processing in a manufacturing enterprise. SDS model is applied to simulate non stationary (dynamic) behaviour of the system. This dynamic behaviour emerges from lack of automation (process variabili...

One way to reduce costs in companies is decreasing inventory levels and improving the value flow. In the present case study a production line where automotive door seals are manufactured was analyzed. First, an analysis with the use of value stream mapping was undertaken in order to identify processes and a material flow. The current state and futu...

The paper presents the application of Multiagent Based Simulation to analysis of supply chain behavior. As has been shown in the paper, agent oriented approach may be considered as a powerful conceptual framework for organization modeling and workbench for simulations of intra- and inter-organizational business processes. All of these theses have g...

Determination of the bending moment and springback coefficient of thin-walled open structural profiles, as a function of the bending curvature was the main objective of the work. The experiment was carried out using angle- section beams (L-shape) made of St3S common steel and channel-section beams (U-shape) made of PA38 aluminium alloy. Distortion...

The main aim of the paper is to show that an agent paradigm may be considered asapowerful conceptual framework for organization modeling and testbed for business simulations. The sections of the paper gradually prove these theses. Firstly the agent orientation has been presented as asource of natural and very intuitive modeling constructs and compl...
