The development of machinery performance monitoring systems along with the prospect of intelligent factories developed under the concept of industrial revolution 4.0 affect dynamic changes in the field of maintenance. Therefore, based on an overview of the literature and observations of production enterprises, we propose a model of maintenance service support system with respect to failure prediction and decision making in the area of maintenance works. In the designing stage the QFD method was employed with a view to testing its usefulness for the process.

“…The electrical tomography is a technique of imaging the distribution of conductivity or permittivity inside the tested object from measurements of the distribution of potentials on the object surface. Many different techniques can be used for the optimization process [10,12,16,24,25]. Figure 2 shows surface electrodes, while the wall with measurement system is presented in Fig.…”

The article presents an innovative solution for assessing the moisture level of walls and building condition. The use of modern tomographic techniques allows for a non-destructive and very precise spatial assessment of the humidity level. Prepared constructions contain special electrodes for measuring humidity in a brick wall. The proposed application solves the inverse problem in electrical tomography. A level set method was used to reconstruct the images.Streszczenie. W artykule przedstawiono innowacyjne rozwiązanie do oceny poziomu wilgotności ścian i stanu budynku. Zastosowanie nowoczesnych technik tomograficznych pozwala na nieniszczącą i bardzo precyzyjną ocenę przestrzenną poziomu wilgotności. Przygotowane konstrukcje zawierają specjalne elektrody do pomiaru wilgotności w ścianie z cegły. Proponowane zastosowanie rozwiązuje problem odwrotny w tomografii elektrycznej. Do rekonstrukcji obrazów użyto metody zbiorów poziomicowych (Tomografia hybrydowa do oceny poziomu wilgotności ścian i stanu budynku).

“…At present, a significant trend can be watched for the robotization of modern procedures, which is firmly identified with process control. The need to automate the control of innovative procedures is one of the fundamental purposes behind the dynamic improvement of IT information handling strategies [3], [4]. Simulation and experimental tests are an important condition for optimizing the control of processes carried out by liquid and suspension mixing systems that under certain circumstances can crystallize [5].…”

This paper presents the original Electrical Impedance Tomography (EIT) imaging algorithm in relation to physic-chemical processes of crystallization. Thanks to the developed method based on artificial neural networks (ANN), it was possible to develop an algorithm that could allow effective detection of crystals and other inclusions inside the reactor filled with non-Newtonian fluid. The neural controller contains a structure of independent neural networks. The number of ANNs corresponds to the resolution of the output image mesh. Streszczenie. W artykule przedstawiono oryginalny algorytm obrazowania z wykorzystaniem elektrycznej impedancji tomograficznej (EIT) w odniesieniu do fizykochemicznych procesów krystalizacji. Dzięki opracowanej metodzie opartej na sztucznych sieciach neuronowych (SSN) możliwe było opracowanie algorytmu, który umożliwiłby skuteczne wykrywanie kryształów i innych wtrąceń wewnątrz reaktora wypełnionego płynem nienewtonowskim. Sterownik neuronowy składa się z systemu niezależnych sieci neuronowych. Liczba SSN odpowiada rozdzielczości siatki obrazu wyjściowego.
