What is Computer‐integrated Manufacturing?

In recent times data processing systems have become increasingly powerful and rapid advances have been made in machining and processing technologies. Growth in materials requirements planning (MRP) and computer‐aided design (CAD) has developed in parallel but independent of the advanced manufacturing technology stream. If organisations are to reduce their reaction time to customers’ orders and to provide a truly flexible service these two main streams must be brought together. This is likely to occur through computer‐integrated manufacturing (CIM). An analysis of the various definitions of CIM is given and implies that there is no single “right” definition which can be applied to any organisation. However there are certain principles which apply to definitions of CIM and an attempt is made to highlight these principles. CIM is not limited to the manufacturing function. It must be an overall concept that takes account of every aspect of the business, tying all aspects and organisational functions together into an integrated system, where all necessary data can be accessed easily by those who need them. CIM does not necessarily mean total computerisation but computers and software will play a major part.
