Object-Orientation is a powerful approach to managing complexity, which has receivedwidespread attention in the past few years. Object-Oriented Design is based on a small numberof basic concepts: object, classes, operations and relationships. Some important relationships areinheritance, message passing, and encapsulation. Different methods and notations have beenproposed within this paradigm, and a Unified Modeling Language has been developed based onseveral of these methods.Most rule-based expert systems are not flexible enough to handle problems that mixlogical deductions, rule-based inferences, and procedure execution, but mixed problems arecommon in modern society. Management decisions, for example, are often based on both rulesand operations-research techniques. These problems cannot be solved by either a conventionalexpert systems or common operation-research techniques alone. Their solution demands a newsystem architecture that effectively combines rules and procedures. The emergence of the expertsystems in operational settings has been the result of intensive research over the past decades.However, while considerable progress has been made in developing the conceptual basis forexpert systems, the means to evaluate them lag for behind.Accidents can happen to workers using a tool or piece of technology due to lack oftraining, a fault in machine or tool, somebody else's fault, etc. The TEXPERT project aims toreduce the misuses and abuses of human resources. The major research objective of theTEXPERT project is to develop an expert system that will evaluate product design for safety andhealth-....,....-...,..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
