Abstract

Due to complexity of customer’s requirements and drastic technological changes,today’s development of automotive product is becoming complex and requires intensive knowledge and information.The accurate knowledge and information focusing on products and processes are crucially required to avoid mismatch information that affect the production of products that meet customer’s requirements.Unfortunately,the current approach of eliciting knowledge and information that describes the common attributes of automotive products is problematic as it lacks formalism of automotive products.In this study,we propose the use of ontology to represent the knowledge of automotive products.This paper presents an approach to describe the common attributes of automotive products using a Formal Attribution Specification Template (FAST).The attributes identified by FAST is formal attributes that can be used to develop ontology. The formal attributes are expressed in terms of its mereological and topological structure and it involves with one or more processes.Our study shows that FAST is efficient and useful for describing automotive attributes,which can improve the elicitation of accurate automotive requirements and provides the design rationale of ontology.The proposed approach was applied in designing an electric vehicle domain library of requirements on the product and process of electric vehicle manufacturing.Here,electric vehicle industrial requirements focusing on the product and process is analyzed using the key structural patterns based on the concept of functional requirements.A case study based on two different electric golf buggies:1) 2 seater golf buggy and 2) 4 seater executive buggy is conducted to derive the requirements.It is found that the developed electric vehicles domain library will be able to assist to the development of market-driven manufacturing of electric vehicles that believed is aligned with the development of green technology. TestMEReq with a template-based tests authoring to assist the requirements engineers in writing quality test requirements and test cases for requirements validation at the earliest stage of requirements engineering process.We embed an English language parser that checks the correctness of the test requirements and test cases written by the requirements engineers.In addition,prompt notification and highlight are also provided to visualize the errors and alert the requirements engineers.We conducted a user study to evaluate the usability of the tool and its effectiveness in helping novice requirements engineers to write quality tests.
