The Development and Implementation of a Computer Based Maintenance Information System

Abstract

The installation of a Maintenance Information System in the Dunlop UK Tyre Division factory, Fort Dunlop is explained. This was achieved by developing two computer systems, one for on-line stock information and the other for job recording. Both systems use the IBM 370/158 computer at the Fort Dunlop factory. The stock information system is also available on remote terminals at the Tyre Division factories at Washington (Tyne and Wear) and Inchinnan (Scotland). The thesis reviews Dunlop's situation in the late 70's, the manufacturing and maintenance functions at Fort Dunlop and explains the benefits of using data processing to provide a Maintenance Information System. This information has been made available at Fort Dunlop to Engineers, Managers and Buyers on VDU Screens in the maintenance workshop offices, stores and purchasing offices. The following features are provided:- a Catalogue of items stocked in 64 Dunlop factories . Stock records for the 3 UK Tyre Division factories : Parts can be requisitioned from stock by keying in an order at any terminal. This updates the stock record and prints a requisition at the factory stores. . Stores receipts, returns and transfers are keyed into a@ stores terminal. This updates the stock record and produces all documentation. The Job Recording system is based on a Work Order Card used to record details of all maintenance work and incorporates a Category Estimation Incentive Bonus scheme, The data from these cards are analysed weekly to provide plant history and management information. The information will be used by management to improve the efficiency of the plant and provides the foundation for a planned preventive maintenance scheme in the near future. Further applications of data processing within the maintenance department are described and the thesis concludes that data processing is a useful, inexpensive maintenance management tool only now beginning to gain recognition. It is emphasised that all the system's potential users, from shop-floor to senior management, were involved in the systems developments, as this produces a better design and helps ensure a successful system implementation.
