An improved method of operation is provided for a catalytic, low pressure process for continuously reforming a hydrocarbon charge stock boiling in the gasoline range in order to produce a high octane effluent stream in which process the hydrocarbon charge stock and hydrogen are continuously contacted in a reforming zone with a reforming catalyst containing a catalytically effective amount of a platinum group metal at reforming conditions including a pressure of 25 to 250 psig. The improved…

Development of an Architecture for a Hybrid Manufacturing Information System
The architecture required for the formation of this Hybrid Manufacturing Information System (HMIS) is described, and this system is tested in a real company to evaluate its viability in an industrial environment.
A General Theory for the Evolution of Application Models - Full version
A delimitation of the concept of evolution is provided, resulting in a first attempt to a general theory for such evolutions, applicable for a wide range of modelling techniques, including object-role modelling and object oriented techniques.
The overall objective of STEP (ISO-10303) is to become the world-wide standard for the representation and exchange of product data. This is to be achieved by the provision of a mechanism capable of
Data-Driven Modeling and Coordination of Large Process Structures
The COREPRO framework for the data-driven modeling of large process structures reduces modeling efforts significantly and provides mechanisms for maintaining data- driven process structures.

This thesis proposes a modelling framework i* (pronounced i-star) consisting of two modelling components: the Strategic Dependency (SD) model and the Strategic Rationale (SR) model, which describes a process in terms of intentional dependency relationships among agents.
CAPE construction application protocol for data transfer : a building data model
Construction is a process, which involves diverse parties having different professional skills and interest. At present, the co-operation and information exchange between parties involved in any
Evolution of data modeling for databases
The scope of data modeling now extends far beyond what it was in the early days of file-oriented systems; many organizations are embarking on corporate data modeling as a part of the strategic planning activity.
Asset management data warehouse data modelling
A novel conceptual data warehousing data model that integrates the numerous asset management data areas is presented, found that the case-based reasoning system provided a marginal benefit, with a greater benefits gained when confronted with more difficult scenarios.
From Business Functions to Control Functions: Transforming REA to ISA-95
This paper demonstrates how a model describing the main business functions of an enterprise is used to derive essential concepts relevant to the manufacturing execution system.
Quality of Conceptual Data Models
This paper presents a specialization of a general framework for assessing quality of models based on organizational semiotics for being able to evaluate the quality of conceptual data models and results in a useful deepening of the generic SEQUAL-framework.
