Remanufacturing, a popular term in the automotive industry, helps to reduce the need for raw materials, increase profitability, is an effective solution to the challenges of postal items and also benefits the environment. For the remanufacturing department, the reliability and failure rate of serial products is particularly important, and therefore the accurate prediction of failure rates is also important. It must be ensured that the product meets its reliability requirements. Existing one, two and three dimensional reliability prediction models predict field failures as a function of time, based on the stress experienced by the components/systems in the field until failure. The existing models have been extended to include the parameters that allow us to predict the reliability of refurbished systems. Improvements such as registration delays, reporting delays and the corrected candidate calculation, which deals with whether the product is still within the warranty period after the observation period, are present in the models and are applied to the systems. This reduces the incompleteness of warranty data due to the influence of external factors with MATLAB. The reliability of systems can be predicted with the lifetime prediction and further conclusions can be drawn for future development. In the verification process, the predicted field failures of the models are compared with the real field failures. ©ESREL2020-PSAM15 Organizers.

To remanufacture automobile systems, it is important to understand the future failure rate of the serially produced systems. In addition, remanufacturing departments need the information about the number of cores to remanufacture, the condition of these cores, as well as the number of replacement systems the market needs. Based on the existing univariate, bivariate and multivariate models a new improved forecasting model is developed, which considers practical factors like export of the vehicle to other countries, damage of the entire vehicle, reporting delay between production and in-market time or between vehicle failure and failure reporting time. This paper presents all necessary tools to achieve the improvement and its implementation in MATLAB. Copyright © 2019 European Safety and Reliability Association.

Nowadays the information of future rates of systems produced in series appears to be crucial to the production plan, especially for remanufacturing departments. Several questions need to be answered: the number of cores to remanufacture the condition of those cores as well as the number of replacement system the market requires. Based on a bivariate prognosis model, a multivariate model is developed to take more variables of stress in field into account. What's more, the fitting process has been optimized by using neural networks. This paper presents all necessary tools to perform a multivariate lifetime prognosis as well as the implementation in MATLAB. © 2019 European Safety and Reliability Association.

The authors present their latest research results and developments of a code generator for Matlab / Simulink block diagrams and to download the generated code onto safety related systems such as a safety PLC (Programmable Logic Controller). An example demonstrates the different stages for code generation, evaluation and conversion before such code can be used in process industries. systematic approaches are necessary when such source code is embedded in process units. To the best knowledge of the authors, Matlab/Simulink source code has not been transferred on safety PLC before. Matlab / Simulink is an advanced and matured programming environment, especially for simulations of engineering processes and systems. Hardly no hardware exists, when it comes to download the developed algorithms and to use it in real world applications and so far this approach is the only one for using developed and tested Matlab / Simulink software on an safety related system. © 2008 IEEE.

Modular Fault Diagnosis in Fixed-Block Railway Signaling systems

The diagnosis of possible faults in railway signaling systems is an important issue to provide safe travel and transportation in railways. Signaling system designers have to consider the possible faults which may occur in railway field components both on the requirements preparation phase and on the development phase of the signaling system software or namely, the interlocking system. Although the diagnosis of different unobservable faults is relatively hard, especially for large scale railway fields, this complexity can be overcome by using the Discrete Event system (DES) based modular diagnosis approach which is explained in this paper. The main advantage of using such modular approach for fault diagnosis in fixed-block signaling systems is the inspection of the diagnosability of the whole system with respect to its subsystems (railway field components). In this study, the diagnosability of the railway field equipment and the whole system is also explained with a case study. © 2016

ICONS International Conference on systems

作者： Josef Borcsok Sebastian Schaefer Department of Computer Architecture and System Programming University of Kassel Germany

Safety-related systems mostly comprise hardware and software solutions. Due to the increasing application of complex hardware and software systems, the software systems have to be considered regarding safety as well as hardware systems. The development of a safety-related software system is similar to the development of a safety-related hardware systems. But there are still no generally accepted methods for developing safety-critical software. One has to use the methods, which fit best to the actual requirements. However, the calculation of reliability and availability for safety-related software systems is far more complex.

Independent mobility is an important feature of an individual's normal life and with the elderly population continually growing, assistive devices such as walkers and canes provide help and guidance to users. Freezing of Gait (FoG) is an episodic phenomenon that is a common symptom of an age-related disease known as Parkinson Disease (PD). This paper is headed toward implementing a detection, diagnosis and correction system for FoG episodes. The proposed cane will generate visual, auditory and tactile cues to help patients overcome this problem, therefore reducing fall risks. In addition, a vibrating calf cuff will be attached to the calf for muscle stimulation. A compatible android phone application is designed to display heart rate measurements of the patient as well as his exact location in case of fall detection. The system is considered to be an electrically safe, portable, comfortable and a low-cost device. The performance of this system is analyzed thoroughly and the accuracy of all methodologies is considered carefully and evaluated. The results have shown no faulty errors and good accuracy and detection percentages. © 2021 IEEE.

The software reliability plays an important role nowadays. From year to year the systems become more and more complex. Consequently, the software becomes more and more complex, too and this can cause more software errors. In this paper a new method is introduced, which serves to predict the reliability of software in a better way. Furthermore, the presumption that the hazard rate is constant is rebutted and a more realistic assumption is made. It is demonstrated that by the use of the new approach the prediction of the number of remaining errors is possible in a better way.

XXII International Symposium on Information, Communication and Automation Technologies, ICAT

作者： W. Chaaban M. Schwarz B. Batchuluun H. Sheng J. Börcsök Department of Computer Architecture and System Programming University of Kassel Kassel Germany

This paper is concerned with the design procedures of an automated testing tool, developed in Matlab ® /Simulink ® environment, that performs software verification during runtime on a PLC (Programmable Logic Controller) or so called HiL test (Hardware-in-the-Loop) for model-based development of control applications. In addition to checking the “semantic” or “functional” correctness of the automatically generated C++ - Code with RTW (Real Time Workshop ® ) for algorithms designed and developed in Simulink ® on hardware targets, the tool compares results obtained from the HiL test with the results of the MiL test (Model-in-the-Loop) performed in early stage of development for the same developed application. The main purpose behind this work is to develop reliable software that fulfil system requirements and to test its behaviour during realtime hardware simulation, in order to achieve the validation step which represents the terminating - step of almost all projects.
