(89d) An Intelligent Supporting System for Safety Instrumented Systems Design for Enhanced Reliability and Availability

Safety Instrumented System design and operation is a complicated task and usually requires experts to perform it. Designing and successfully maintaining each phase of the Safety Life Cycle (SLC), defined by international standards, can also be time-consuming and very expensive. To avoid this problem and help the user to carry out analysis of minimal parts of the SLC, different supporting tools have been developed. However, these tools are complicated for the user and for some case, expensive. In this research, we propose and develop a SIS supporting tool for the analysis of the reliability of a given system, in the form of Android application. Our model avoids all the unnecessary user input parameters that have been challenging for the user. This reduction of parameters makes our tool easier to use, and compared to already developed tools the time required to perform reliability assessment becomes shorter. The supporting tool also contains a huge database of failure rates of Sensor, Logic Solver, and Final Element, included and continuously updated from different sources. This database can be modified or updated based on the user application area.
