Mark S. Fox: Enterprise

“In enterprise modelling, we want to define the actions performed within an enterprise, and define constraints for plans and schedules which are constructed to satisfy the goals of the enterprise. This leads to the following set of informal competency questions:”

Mark S. Fox

Temporal projection - Given a set of actions that occur at different points in the future, what are the properties of resources and activities at arbitrary points in time?
Planning and scheduling - what sequence of activities must be completed to achieve some goal? At what times must these activities be initiated and terminated?
Execution monitoring and external events - What are the effects of the occurrence of external and unexpected events (such as machine breakdown or the unavailability of resources) on a plan or schedule?
Time-based competition - we want to design an enterprise that minimizes the cycle time for a product. This is essentially the task of finding a minimum duration plan that minimizes action occurrences and maximizes concurrency of activities.

Question

“As information systems play a more active role in the management and operations of an enterprise, the demands on these systems have also increased. Departing from their traditional role as simple repositories of data, information systems must now provide more sophisticated support to manual and automated decision making; they must not only answer queries with what is explicitly represented in their Enterprise Model, but must be able to answer queries with what is implied by the model. The goal of the TOVE Enterprise Modelling project is to create the next generation Enterprise Model, a Common Sense Enterprise Model. By common sense we mean that an Enterprise Model has the ability to deduce answers to queries that require relatively shallow knowledge of the domain.”

“Various perspectives exist in an enterprise, such as efﬁciency, quality, and cost. Any system for enterprise engineering must be capable of representing and managing these different perspectives in a well-deﬁned way.”

Way

“There is a paradigm shift towards a distributed and integrated enterprise. Currently, computer systems that support enterprise functions were created independently. This hampers enterprise integration Therefore, there is a need for a computer based data model which provides a shared and well deﬁned terminology of an enterprise, and has the capability to deductively answer common sense questions.
This paper discusses how TOVE tackles these needs by deﬁning a framework for modeling generic level representations such as activities, time, and resources. Since there has never been a well-deﬁned set of criteria to evaluate such models, this paper also introduces a set of evaluation criteria which may be used to evaluate modelling efforts.”
