چکیده

This paper illustrates a prototype system, called GPRS, supporting the Generalized Production Rules (GPR) database language. The GPR language integrates, in a uniied framework, active rules, which allow the speciica-tion of event driven computations on data, and deductive rules, which can be used to derive intensional relations in the style of logic programming. The prototype realizes the operational semantics of GPR using a unique rule-evaluation engine. The data model of reference is object based and the system is implemented on top of an object oriented DBMS. Hence, the GPRS prototype represents a concrete proposal of an advanced DBMS for complex objects that provides both active and deductive styles of rule programming. c

Integrated Process Planning and Active Scheduling in a Supply Chain-A Learnable Architecture Approach

Through the lens of supply chain management, integrating process planning decisions and scheduling plans becomes an issue of great challenge and importance. Dealing with the problem paves the way to devising operation schedules with minimum makespan; considering the flexible process sequences, it can be viewed as a fundamental tool for achieving the scheme, too. To deal with this integration, t...
