  The dawn of the fourth industrial revolution, Industry 4.0 has created great
enthusiasm among companies and researchers by giving them an opportunity to
pave the path towards the vision of a connected smart factory ecosystem.
However, in context of automotive industry there is an evident gap between the
requirements supported by the current automotive manufacturing execution
systems (MES) and the requirements proposed by industrial standards from the
International Society of Automation (ISA) such as, ISA-95, ISA-88 over which
the Industry 4.0 is being built on. In this paper, we bridge this gap by
following a model-based requirements engineering approach along with a gap
analysis process. Our work is mainly divided into three phases, (i) automotive
MES tool selection phase, (ii) requirements modeling phase, (iii) and gap
analysis phase based on the modeled requirements. During the MES tool selection
phase, we used known reliable sources such as, MES product survey reports,
white papers that provide in-depth and comprehensive information about various
comparison criteria and tool vendors list for the current MES landscape. During
the requirement modeling phase, we specified requirements derived from the
needs of ISA-95 and ISA-88 industrial standards using the general purpose
Systems Modeling Language (SysML). During the gap analysis phase, we find the
misalignment between standard requirements and the compliance of the existing
software tools to those standards.
