Extensions to iCAM, a Constraint-Based Knowledge Maintenance System

چکیده
Knowledge maintenance is imperative if knowledge-based applications are to be kept functional throughout their lifecycle. Our iCAM system uses constraint-based reasoning to carry out knowledge maintenance in the domain of hospital material management. In this paper, we present two extensions to this system. The first is the application of the constraint hierarchy formalism to represent priorities among constraints. The second is the incorporation of the constraint tagging and audit trails into the constraint representation itself to support “dynamic constraints”. Including dynamic constraints of this type in iCAM’s constraint knowledge base can automate some of the user’s maintenance tasks.

A Dynamic Fuzzy Expert System Based on Maintenance Indicators for Service Type Selection of Machinery
Due to the multiplicity of standards and complex rules; maintenance, repair and servicing of machinery could be done only by the fully qualified and proficient experts. Since the knowledge of such experts is not available all times, using expert systems can help to improve the maintenance process. To address this need and the uncertainty of the maintenance process indicators, this research prop...

General preventive maintenance model for the components of a system, which improves the reliability to ‘as good as new,’ was used to optimize the maintenance cost. The cost function of a maintenance policy was minimized under given availability constraint. On the other hand, in order to ensure appropriate reliability and availability, the development of the optimal maintenanc...

This paper considers a multi-period, multi-product inventory-routing problem in a two-level supply chain consisting of a distributor and a set of customers. This problem is modeled with the aim of minimizing bi-objectives, namely the total system cost (including startup, distribution and maintenance costs) and risk-based transportation. Products are delivered to customers by some heterogeneous ...
متن کاملInteractive Connguration Using Constraint Satisfaction Techniques
In this paper, we focus on techniques for incremental constraint-based conngu-ration with discrete and continuous variables. We show how to formalize constraint knowledge using compatibility and activity constraints (Mittal 1990) and how this knowledge is used for reasoning within an intelligent CAD system. Most technical (as opposed to spatial) constraint connguration systems use algorithms fo...

Stochastic flexible flow shop scheduling problem (SFFSSP) is one the main focus of researchers due to the complexity arises from inherent uncertainties and also the difficulty of solving such NP-hard problems. Conventionally, in such problems each machine’s job process time may encounter uncertainty due to their relevant random behaviour. In order to examine such problems more realistically, fi...
