M.Ing. / As the manufacturing environment evolved over the past century, the nature of investments in manufacturing capabilities changed dramatically. Automation can be seen as the single biggest driver of this evolution; enabling the manufacturing fraternity to develop smarter technology in order to exploit the opportunities that were created by the volatility that exist in most markets. This lead to the development of flexible manufacturing technology. Constructing a definition of manufacturing flexibility is difficult mainly due to the various views and perspectives that exist of flexibility. In short, flexibility can be defined as the ability to react ( to any change ) with little penalty in time, effort, cost or performance. These technologies that enable a manufacturing system to be flexible in a certain manner are generally difficult to justify in terms of traditional financial yardsticks. This can be contributed to the diverse benefits to be gained from these investments; and often these benefits are of a nonfinancial nature. Furthermore, when reviewing investments in flexible manufacturing technology within a process environment there appears to be an even bigger problem. The relatively fixed nature of the design output of process equipment, and the enormous quantities of capital outlay initially required to erect and commission process plants, often makes it near impossible to justify any investment that does not deliver good financial returns within the short term. Thus it becomes clear that the traditional methods of investment appraisal within the process environment have become generally unsuitable; and this call for a re-evaluation of the processes applied to guide value adding investments. This study set out to deliver a logical approach to appraising investments in manufacturing flexibility by defining a framework to be applied. The proposed framework consists of the following 4 primary steps. Firstly the strategic direction followed by the business is defined; then an analysing of the manufacturing flexibility required is performed. The third step is to evaluate the manufacturing technology available and furthermore a suitable performance measured criteria is defined to evaluate the proposed investment. This model is set within the strategic context of the manufacturing strategy of a business and thus should ensure the development of manufacturing capabilities that will ensure business growth over the medium to long term.
