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. This article presents a method for optimizing the flow of the brake caliper remanufacturing process in the MTO (make-to-order) model. For the optimization process, the system dynamics (SD) method, which belongs to a group of simulation methods, was used. The developed model allows, in particular, the prediction of the number of components at the input to the regeneration process and the method of defining the size of the transport batch and evaluating its impact on the length of the production cycle of the batch of regenerated products. The issues of staffing management at individual positions and the organization of transport operations with variable production batch sizes were also discussed. The provided experiments have shown that reducing the size of the transport batch contributes to shortening the production order execution time, both with standard and increased staffing.

The aim of the paper is to assess the impact of the effectiveness of bonding steel elements with paint coating. The adhesive joints were made using two types of the adhesives: two-component epoxy resin adhesive based on Bisphenol A and polyurethane. Three types of adhesive joints were made: (i) reference samples, (ii) samples with a paint polyester coating, and (iii) samples with a zinc primer and paint polyester coating. These coatings were applied using the electrokinetic method. A shear strength test of the adhesive joints (EN DIN 1465 standard), a coating adhesion test (ASTM D3359-B standard), and surface wettability tests (based on contact angle) were used. Through analyzing the test results, it can be seen that the strength of the adhesive joints of the reference samples made with epoxy adhesive is 46% lower than that of the specimens with primer and paint coating applied. However, in the case of the adhesive joints made with the polyurethane adhesive, the aforementioned difference in the strength value of the adhesive joints of the reference samples and paint-coated samples with an applied primer is 76%. Adherends with a paint coating and a previously applied primer obtained the lowest value of the contact angle (38.72°) and are characterized by good wettability.

This paper presents a non-invasive diagnostic approach for Electric Parking Brake (EPB) modules based on recurrence quantification analysis (RQA) of piezoelectric vibration data. Vibration signals were collected from sensors mounted on the motor, planetary gearbox, and pinion under five predefined fault conditions: missing gear in the lower row of the planetary gearbox, missing gear in the upper row, tooth damage in the planetary gear, partially cut timing belt, and incorrect gear installation. Each failure mode was tested repeatedly to obtain statistically reliable datasets for non-linear time-series and recurrence-based analysis. The following RQA quantificators were computed: Determinism (DET), Laminarity (LAM), maximal diagonal line length ( $$L_{\max }$$ L max ), and mean diagonal line length ( L ) were calculated to characterize the underlying dynamic behavior. Additional recurrence quantificators describing laminar states—Trapping Time (TT) and maximal vertical line length ( $$V_{\max }$$ V max ) were used to capture transient stability and synchronization effects. The results show that these RQA quantificators are highly sensitive to mechanical faults, especially within the gearbox, enabling effective fault localization and differentiation between failure types. The missing-gear condition resulted in increased values of DET, LAM, and $$L_{\max }$$ L max , reflecting more regular and structured recurrence patterns, while incorrect pinion installation produced more irregular and weakly correlated responses. Statistical analyses confirmed that the observed differences between fault conditions were significant, not only within experimental groups, but also between individual RQA quantificators, highlighting their diagnostic discriminative capability. The proposed method allows efficient fault detection without disassembling the EPB unit, thus reducing remanufacturing costs and downtime. Overall, the study demonstrates that recurrence-based diagnostics provide a robust and interpretable framework for real-time condition monitoring and fault prediction.
