Summary: The aim of this study was to develop an innovative solution using the Laplace transform and the R programming language to determine the reliability measure of a system. A mathematical model based on the theory of reliability was established, and actual numerical data were used for calculations and analyses. An algorithm utilizing the Laplace transform was proposed to evaluate the system's reliability. Results showed that the proposed algorithm simplified complex calculations and allowed for visualization of results, making it a universal and cost-effective solution for determining reliability characteristics.

Summary: Requirements are important in software development. Ambiguous requirements lead to problems such as rework and delayed delivery. Extracting actors and use cases from requirement texts is an effective solution. This study proposes a model using BiLSTM and CRF to automatically extract actors and use cases, and the results show significant improvement in accuracy compared to baseline methods.
