An Agent-Based Mechanism for Autonomous Multiple Criteria Auctions

This paper aims at defining an agent-based mechanism for autonomous multiple criteria reverse English auctions which are conducted by software agents that negotiate on behalf of buyers and sellers. We propose models for buyer and seller agents where agents' preference relations can be based on various aggregation models. We introduce pricing functions to let seller agents interpret the buyer agent request and associate a price to their bids in order to make them acceptable to the buyer as well as to their own commercial constraints

Type-Safe Relaxing of Schema Consistency Rules for Flexible Modelling in OODBMS

Object-oriented databases enforce behavioral schema consistency rules to guarantee type safety, i.e., that no run-time type error can occur. When the schema must evolve, some schema updates may violate these rules. In order to maintain behavioral schema consistency, traditional solutions require significant changes to the types, the type hierarchy and the code of existing methods. Such operations are very expensive in a database context. To ease schema evolution, we propose to support exceptions to the behavioral consistency rules without sacrificing type safety. The basic idea is to detect unsafe statements in a method code at compile-time and check them at run-time. The run-time check is performed by a specific clause that is automatically inserted around unsafe statements. This check clause warns the programmer of the safety problem and lets him provide exception-handling code. Schema updates can therefore be performed with only minor changes to the code of methods
