Abstract

PLANNING ANALYST IS AN EXPERT SYSTEM DESIGNED TO CAPTURE, PRESERVE, AND ULTIMATELY TRANSMIT THE EXPERTISE OF MANUFACTURING PLANNERS. MANUFACTURING PLANNING IS A VARIOUS, COMPLEX, AND SUBTLE ACTIVITY THAT CAN BE DIVIDED INTO TWO KINDS OF KNOWLEDGE: MECHANICAL/FACTUAL AND JUDGEMENTAL/HEURISTIC. THE FORMER HAS BEEN SUBJECT TO COMPUTERIZATION, BUT THE LATTER DEPENDS ON THE SPECIFIC EXPERIENCES OF PLANNING EXPERTS AND SO FAR HAS RESISTED QUANTITIVE ANALYSIS. HEURISTIC KNOWLEDGE GENERATES THE INDIRECT MANUFACTURING COST FACTORS AND REMAINS THE MOST CRITICAL CONTROL ON PRODUCTIVITY AND PROFITS. PLANNING ANALYST WILL CREATE A KNOWLEDGE BASE THAT ACCOUNTS FOR FACTUAL AND HEURISTIC DATA. TO SUPPORT THE KNOWLEDGE GATHERING EFFORT, THE DESIGNERS WILL CONSTRUCT A KNOWLEDGE ENGINEERING LANGUAGE ABLE TO ACCEPT INPUTS IN ENGLISH LANGUAGE, AND WILL SUPPLEMENT THEIR KNOWLEDGE ENGINEERING STAFF WITH KNOWLEDGE EXPERTS WHOSE SKILLS LAY DIRECTLY IN MANUFACTURING PLANNING AND IN UNDERSTANDING THE MECHANICS OF INFORMALLY TRANSMITTED KNOWLEDGE. PLANNING ANALYST WILL CHAIN FORWARDS AND BACKWARDS THROUGH FRAMES AND RULESETS, AND WILL OTHERWISE FEATURE THE USUAL CHARACTERISTICS OF INFERENCE DRIVEN KNOWLEDGE SYSTEMS.
