FROM ISLANDS OF AUTOMATION TO THE NEW WORLD OF UNIX

CIM (Computer Integrated Manufacturing) is usually viewed as a vast and complex undertaking which only the General Motors of this world can afford. This article puts forward a simple CIM strategy based on a building block approach using UNIX (the industry standard hardware independent computer operating system). This approach ensures companies start with systems they can afford and also manage. Risks are decreased, small companies too can now build their own CIM strategies. UNIX's great strength is portability and flexibility: companies can start with basic MRP systems and build upon those, integrating at will the more specific elements of CIM as they are needed. The suitability of UNIX for this “mix and match” approach is examined. No longer is there any need to be locked in to one hardware or software supplier. Competitive edge too is improved as the manufacturer can respond quickly to the fluctuating nature of the consumer market. As new products are required, new computer control systems can easily be integrated with the core system.
