A dissertation submitted to the Faculty of Engineering, University of the Witwatersrand, Johannesburg, in fulfillment of the requirements for the degree of Master of Science in Engineering. / This dissertation shows that the engineering information system (EIS) is the primary integration mechanism in computer integrated manufacturing. The EIS has been defined by creating a functional as well as an information model. These models are the initial steps in the process of implementing an EIS by means of a database management system. The modelling of the EIS is defined within a work brealcdown structure for CIM acquisition which is applicable to any CIM project. The impact of the scope CIM of and the changes this requires are also defined. It is also shown that for an enterprise involved in the manufacture of complex systems it is more beneficial to introduce CIM in those areas outside the area of factory automation, The complexity of the EIS information model is such that it has not been possible to construct it manually. Automated tools should be used to create the EIS information model. / Andrew Chakane 2018
