Self-improving work instruction system

Abstract

Information to set up various audit procedures is input through an operator terminal (10) to an audit revision processor (120). The audit revision processor creates various audit points by creating an audit point identification and the various audit parameters including identification of an item on which the audit is performed, the nature of the defects sought by the audit, any test fixtures used in the audit, standards, dimensions, or tolerances against which the item is tested, and the like. Once a series of audit points are created, the operator uses a video monitor (12) and a mouse (14) in a point and shoot manner to identify a selected audit from an audit look-up table (40) which retrieves a corresponding audit point identification. The audit point identification is supplied to memories (42, 50, 60) which provide corresponding information for display on the monitor (12) and which provides an initial address information to a sampling matrix (80). The audit identification selects a range of percentages of designated items to be audited plus an initial percentage. The initial percentage point determines a sample rate for a test fixture (86). Defects are input manually (116) or automatically and stored in a history memory (90). A defect analysis routine (94) analyzes the feedback defect information. Based on this comparison, the defect analysis circuit addresses the sampling matrix (80) to increment and decrement the sampled percentage within the selected range.
