Measuring Maintainability of DPRA Models: A Pragmatic Approach
Dynamic Probabilistic Risk Assessment (DPRA) is a powerful concept that is used to evaluate design and safety of complex industrial systems. A DPRA model uses a conceptual system representation as a formal basis for simulation and analysis. In this paper we consider an adaptive maintenance of DPRA models that consist in modifying and extending a simplified model to a real-size DPRA model. We pr...

متن کاملMaintainability Policy for Deteriorating System with Inspection and Common Cause Failure (TECHNICAL NOTE)
A condition based preventive and corrective maintenance policy is proposed for a continuously operating system. The condition of the system is assumed to deteriorate with time. The model incorporates both deterioration as well as random common cause failures. The deterioration stages are modeled as discrete state processes. The system is put to random inspection to know the condition. The mean ...
متن کاملFuzzy Layered Approach for Maintainability Evaluation of Object Oriented Software System
A large number of software products enter the maintenance phase due to the growing application of information systems. Software maintenance is the modification of a software product after delivery to correct faults and improve its overall performance and quality. Easily maintainable software saves large costs and effort involved in developing the software. Hence maintainability assessment is an...
متن کاملAssessing Software Maintainability Based on Class Diagram Design : A Preliminary Case Study Yao
Can software maintainability be assessed at the early design stage? For a preliminary answer, we conducted a case study. The study adopts a set of metrics for class diagram measurement, and defines three indices for maintainability assessment from the defect-correction perspectives. The dataset under investigation includes the defect repository and corrective maintenance history of Apache Tomca...
