Goal Structuring Notation for Engineering Safety Case
Project Area of Specialization Shared EconomyProject Summary“Goal Structuring Notation for Engineering Safety Case” is a tool that is unambiguous, structured, efficient and mature approach to develop and present safety arguments. This tool will define the limitations and standards and fulfill the requirements which an individual need to get for their goal and give a way to provide better solutions. GSN explicitly represents the individual elements of any safety argument (requirements, claims, evidence and context) and relationships that exist between these elements.
The use of GSN has arisen in response to poorly written Safety Case documents. Such safety documents may easily become lengthy and obtuse for users through poor use of English and it becomes hard to tackle a common weakness in technical and complex arguments. Due to the amount of manual work, constructing a safety case is usually time-consuming and lacks clarity in written documents.
Therefore, A Goal Structuring Notation (GSN) tool is presented to support a user to draw a structure of engineering arguments and Data flow while taking technical arguments and following standards. The tool has basic GSN shapes and providing the services of data flow in technical and critical arguments, and a mature drawing tool.
Project ObjectivesObjectives are:
- Reduce implications of faulty safety cases
- Reduce training work
- Reduce health concerning issues.
- Improve authentication and correction of mistakes
- increase efficiency and effectiveness.
These above objectives are achieved by GSN tool features i.e.:
- Team Management.
- File import/export in .png and .dmo extensions.
- Guided and Restricted drawings by GSN standards for safety cases.
Algorithm:
1) START
2) Identify goals.
3) Identify sub-goals, if more than one goal.
4) Identify strategies, if more than one then repeat this step until completed.
5) Identify solutions, if more than one solution then repeat this step until completed.
6) Check goal is achieved.
7) Go to step 3 for remaining goals.
8) END.
Flowchart:
- GSN is increasingly being used in safety-critical industries and in every engineering field where safety is concerned.
- GSN improves the comprehension of the safety argument amongst all of the key project stakeholders (i.e. system developers, safety engineers, independent assessors and certification authorities).
- It visualizes an argument structure that supports a claim to be true.
- It provides the spell check feature of every written argument.
“Goal Structuring Notation for Engineering Safety Case”is a tool that is unambiguous, structured, efficient and mature approach to develop and present safety arguments. This tool provide standard and limitations on these standards for better work. This tool has home page, user manual for user guidance and GSN tool that is used to develop safety cases in every field of engineering. GSN tool provide us login and sign up page for users. After login we can use the tool. We draw safety case, tool will provide restrictions on each standard. We specify unique keyword for each standard. When we follow the restriction then we can proceed to drag the next element of GSN tool.
This tool has color scheme. We can change background color, text color, font size canvas size (height and width). After draw safety case we can save, import, export and open the safety case diagram for future use.
In setting feature, registered user can also change its password. We can add unregistered user users by the registerd user for team work.
