Risks and implications for decision-making processes associated with existing design codes or their non-existence
(AGH University of Science and Technology Press, 2018) Błachut, Jan; Sala, Dariusz
The buckling phenomenon is a perplexing and unresolved issue in many safety critical structures, as a result, it has been heavily regulated. The existence of regulations would normally benefit modern decision-making tools. But there are various obstacles coming from real-life situations. In order to illustrate the above and draw awareness to the problem, the paper chooses the buckling of shells and discusses (i) the case of an internally pressurized dome found in a plane's fuselage that failed during a routine flight, (ii) a case where advances in structural mechanics challenge the existing design codes (i.e., metallic domes in pressure vessels), and (iii) a case of extracting rich seabed resources where efficient buoyancy units are required. In the last-mentioned case, the paper points towards the use of advanced carbon fiber plastics (cfrps) and illustrates this by a failed cfrp dome manufactured from a woven fabric (a topic still within the research sphere of activities). Cases of several other industrial failures caused by buckling are also provided. Finally, the paper highlights the risks to the decision-making processes due to the growing tendencies of eliminating the records of disastrous events from public domains through confidentiality arrangements and the erosion of the existing human know-how.
Concept of industry 4.0-related Manufacturing Technology Maturity Model (ManuTech Maturity Model - MTMM)
(AGH University of Science and Technology Press, 2018) Gracel, Jarosław; Łebkowski, Piotr
The main objective of this article is to describe Industry 4.0 and the key manufacturing-technology-related technological and business challenges for manufacturing companies. The groups especially interested in the implementation of Industry 4.0 are the operations, technical, and production directors responsible for operational excellence of manufacturing plants, strategic development, and business continuity. Based on the latest Industry 4.0 and manufacturing technology market research, factories located in Poland are less technologically advanced than their counterparts in Western European plants. Accordingly, development of the model for assessing the current level of maturity for manufacturing technology related to the Industry 4.0 initiative becomes a relevant research task. In the article, key Industry 4.0-related technological areas will be described. Based on extensive research into international references and industrial consulting experiences in the industrial business consulting conducted in Polish manufacturing companies, the manufacturing technology ManuTech Maturity Model (MTMM) concept related to Industry 4.0 will be developed and presented. A substantial and innovative part of the article will be devoted to the adjustment of a proposed maturity model to specific features of the Polish industrial and manufacturing sector. This will be relevant due to the noticeable differences in the levels of technological advancement between the Western and Eastern Europe sectors.
Multi-criteria optimization approach to modeling negotiation process
(AGH University of Science and Technology Press, 2018) Łodziński, Andrzej
This paper presents a multi-criteria optimization approach for modeling the negotiation process. The negotiation process is modeled as a special multi-criteria problem. The method of finding solutions involves a process of the interactive selection of certain proposals. The parties submit proposals concerning the subjects of the negotiations, these proposals constitute the parameters of the multi-criteria optimization problem. Selecting the solutions is accomplished by solving the optimization problem using the parameters that define the aspirations of each party to the negotiations. Finally, the solutions reached by the parties are evaluated.
