EXTENDING DEMO - CONTROL ORGANIZATION MODEL - Modeling an Organization's Viability Norms, Dysfunctions and Resilience Strategies

With our proposal, DEMO can now be used to explicitly specify critical properties of an organization-that we call measures-whose value must respect certain restrictions imposed by other properties of the organization-that we call viability norms. We can now also precisely specify, with DEMO, defined resilience strategies that control and eliminate dysfunctions-violations of viability norms.

APPLICATION OF HOMOMORPHIC FILTERING TO SEISMIC DATA PROCESSING**This work was supported in part by the Advanced Research Projects Agency monitored by ONR under Contract N00014-75-C-0951-NR 049-308 and in part by the National Science Foundation under Grant ENG71-02319-A02

Homomorphic filtering represents an alternative approach to the deconvolution of the seismic signal. This class of filtering techniques represents a generalization of linear filtering to encompass a variety of nonlinear filtering problems. One particular class of nonlinear filtering problems to which it has been successfully applied in a number of applications is that of deconvolution. Within the context of seismic signal processing, a number of approaches have been explored for the application of this class of nonlinear filtering techniques. One consists of applying the method directly to extract the reflector series from the received signal. A second corresponds to using homomorphic filtering to estimate the source pulse. From this estimate, an inverse filter is then designed using one of several possible techniques including Wiener inverse filter design.

Such systems capture the expertise of a specialist in the application of a design techniquefor instance in the development of an analytical model, in the forming of assumptions or in the interpretation of results. An example discussed here is an "expert" aid to be applied within structural analysis using finite element method. The system is constituted from three modules, one for finite element selection, the other for finite element mesh design and the third one for results" interpretation.

The Enterprise Operating System and its Role in the Governance, Viability and Sustainability of Enterprises

We need constructs to better model enterprises as self-observing systems, and not merely as observed systems. We introduce the concept of Enterprise Operating System (EOS), as the emerging enterprise ́s control and governing system, which turns enterprises into autonomous, intelligent, viable and sustainable entities. Our assumption is that all organizations, being complex social-technical systems, evolve to higher complex levels, whereby at some point “organizational autonomous life” emerges as a reification, at a macro systemic level, of the social-technical network of its autonomous agents or its network nodes. This reification is precisely realized by the emergence of the EOS, which turns the enterprise into a kind of autopoietic system, with logical closure, ch...

Enterprise Governance and DEMO Guiding enterprise design and operation by addressing DEMO's competence, authority and responsibility notions

The research brings forward the importance of this organizational competence labeled enterprise governance (EG) in defining DEMO's ontological models and using their subsequent au- thority, responsibility and competence notions to guide the enterprise dy- namics. Based on these results, the article provides a reference method for the EG to define a set of normative outputs, derived from these three notions addressed in the enterprise ontologic models, comprising a set of principles to address enterprise integration and a set of rules to deal with on-going organizational changes while addressing security issues.

A General Process for Developing Business Simulations Games

Proceedings of the 2nd International Conference on Simulation and Modeling Methodologies, Technologies and Applications, 2012

However, human abilities to deal with complex dynamic systems and processes, while behaving in a sustainable way, have not improved to the required extent. One way to deal with complex situation is the simulation approach: build a simplified model of this reality, learn from this simplified model, and, finally, translate the findings or knowledge back to reality. Simulation games are based on this idea. Nevertheless, if we want to make inferences about reality based on experiences and knowledge acquired in a simulation game, we have to be sure that the underlying conceptual model is a good, or valid, representation of the real situation. Based on knowledge gather from the simulation development process and Agent-based Modelling, this paper proposes a general process for developing business simulation games.

Towards Conscious Enterprises: The Role of Enterprise Engineering in Realizing Living Sciences Paradigms into Management Sciences

As-Is Continuous Representation in Organizational Engineering

Proceedings of the Tenth International Conference on Enterprise Information Systems, 2008

However, the use of this model is normally restricted in time in order to support some organizational activities, instead of being a solid foundation to support the organizational daily activities acting as an organizational knowledge repository. This is a result of the difficulty to maintain the model updated and aligned with the reality. The research in Organizational Engineering is already mature in defining modeling artefacts, modelling languages and the necessary views to adequate the model to the users, promoting its usage in a continuous baseline. This paper propose a process to maintain the As-Is Organizational Model updated. The strategy presented considers the organizational model as a representation of the organizational conscience, continuously aligned with the reality.

We introduce the concept of Enterprise Operating System (EOS), as the emerging enterprise self governing system, which turns enterprises into autonomous, intelligent and viable entities. Our assumption is that all organizations, evolve to higher complex levels, whereby at some point "organizational autonomous life" emerges as a reification, at a macro systemic level, of the social-technical network of its autonomous agents. This reification is precisely realized by the emergence of the EOS, enabling the enterpise closure, characterized by its completeness and self-reference, and the preservation of its wholeness and distinctiveness. The EOS should be able to compile in near real time its position and trajectory to assess if is in line with its viable states set and trigger/call for correction actions and self transformations whenever needed. Our research goal is to develop a universal EOS (UEOS) model to design, diagnose and improve the EOS of any organization, by certifying that its particular EOS includes all of the UEOS´s required mechanisms and properties.

The 2014 European Directives on Public Procurement highlight the need for governance measures in Member States. Portugal has been considered a pioneer in electronic Public Procurement and, following Europe's last guidelines, is dedicating attention to a formal governance model set up. A governance model is fundamental to enhancing integrity in Public Procurement, supporting sustainable and inclusive growth, and reinforcing citizens' trust. This study aims to analyse the evolution of Public Procurement governance in the Portuguese state and design a model within the Enterprise Governance context. Our proposal builds on the Enterprise Ontology principles and the design uses DEMO methodology to represent the model. It mainly aims to address the lack of articulation among key public entities and to increase alignment between government strategic objectives and public entities action plans. The result of our study observes the recent OECD recommendations on Public Procurement.

Organizations and Autopoiesis: a Biological Perspective

Maturana and Varela developed the theory of autopoiesis − a biological theory of autopoietic systems − in order to explain the particular nature of living in the physical domain. Their main contribution has been to provide a concise specification of the defining characteristics of living systems, including humans. Several authors, especially the sociologist Luhmann, have tried to extend such theory to social systems, including organizations. Social systems are systems that are based on the interactions of living systems. The question therefore arises if organizations are also autopoietic systems. In this paper, this question and the relevance of the autopoiesis theory are discussed for understanding organizational changes and self-maintenance, from a biological point of view. Supported by the autopoiesis theory, organizations can be interpreted as networks of interactions, processes and rules of coordination.

An engineering approach to natural enterprise dynamics: From top-down purposeful systemic steering to bottom-up adaptive guidance control

These active elements change the state of the world through their individual and collective orchestrated networked actions, in real time. All an enterprise "does" is the sum total of the actions of its active servers. No more, no less! An Enterprise is an entity by itself, whose existence is associated with intentions, missions, goals and purposes that are in some degree shared by its active elements and inform the prescribed organizational elements of its structures. An Enterprise is under permanent change, due to external and internal conditions, and the enacted changes occur either by spontaneous actions of its active servers or by intentional systemic change that propagates top-down and is purposefully adopted by the baseline servers. This talk will show how relevant is the Engineering Body of Knowledge of Systems Theory and Dynamic Systems Control and the formal principles and methods of Enterprise Engineering to model, design and operate Enterprises and in particular, how to steer top-down strategic transformations and to combine them with adaptive bottom-up emergent adaptive phenomena.
