Routines

Agre, Philip E. 01 May 1985 (has links)
Regularities in the word give rise to regularities in the way which we deal with the world. That is to say, we fall into routines. I have been studying the phenomena of routinization, the process by which institutionalized patterns of interaction with the world arise and evolve in everyday life. Underlying this evolution is a dialectical process of internalization. First you build a model of some previously unarticulated emergent aspect of an existing routine. Armed with an incrementally more global view of interaction, you can often formulate an incrementally better informed plan of attack. A routine is not a plan in the sense of the classical planning literature, except in the theoretical limit of this process. I am implementing this theory using running arguments, a technique for writing rule-based programs for intelligent agents. Because a running argument is compiled into TMS networks as it proceeds, incremental changes in the world require only incremental recomputation of the reasoning about what actions to take next. The system supports a style of programming, dialectival argumentation that had many important properties that recommend it as a substrate for large AI systems. One of these might be called additivity: an agent can modify its reasoning in a class of situations by adducing arguments as to why its previous arguments were incorrect in those cases. Because no side-effects are ever required, reflexive systems based on dialectical argumentation ought to be less fragile than intuition and experience suggest. I outline the remaining implementation problems.

Phenomenology and landscape experience : a critical appraisal for contemporary art practice

Unwin, Bren Carolyn January 2008 (has links)
This thesis examines some of the ways in which phenomenology might be applied to the representation of landscape experience within contemporary art practice. In particular, the thesis examines how embodied landscape experience, informed by an understanding of phenomenology, might be articulated by contemporary art practice that uses the media of film and digital video. The thesis also questions ways in which time might contribute to an understanding of such a representation of the landscape. Based on a critical analysis of landscape experience and its representation in art practice, the thesis identifies critical omissions both within the aligned disciplines of cultural anthropology and art history, particularly in instances where art has been employed ineptly as a tool for critical enquiry. Through a conceptual analysis of phenomenology, cultural archaeology, cultural anthropology, theories of technology, art history, critical film theory and art practice, this project makes a critical examination of new ways in which art can articulate phenomenological notions of landscape experience, both in the forms of a written exegesis and in examples of my own practice. To these ends, the writing of Christopher Tilley and Tim Ingold is examined in order to draw upon some of the ways in which cultural archaeology and cultural anthropology use Maurice Merleau-Ponty’s phenomenology and James Gibson’s ecological theory of visual perception to understand an embodied engagement with the landscape. Following an expanded phenomenological examination of landscape the thesis identifies ways in which cultural anthropology has used painting. This examination is followed by an analysis of the work of Mike Michael and Don Ihde in order to determine the role played by technology within the mediation of experience and its representation in art. The writing of Joyce Brodsky is examined to analyse the relationship between embodied experience and art practice and, using Sobchack’s analysis, the thesis describes ways in which Merleau-Ponty’s idea of reversibility can explain moving imagery as the perception and expression of experience. As part of the method of analysis, a case study is conducted into how phenomenological ideas that have been identified in association with landscape experience might be understood within Tacita Dean’s work Disappearance at Sea. An analysis of phenomenological notions of landscape experience within my own art practice has led to the generation of a body of practice that includes film and digital video media. Key examples of my art practice have been selected that can articulate this thesis. Specifically, a 16mm film, Line, and a digital video, Length II provide evidence of contemporary art practice articulating an experience of the landscape from a phenomenological viewpoint. Within the production of moving imagery, there is a sequence of human actions and technological interventions that can be considered in phenomenological terms. Through a reflection of my own embodied experience - extended by vehicles, cameras and their associated technology - Line and Length II pay specific attention to how the placement of a camera and its associated technology mediates the mobile character of an experience of the landscape. Central to this enquiry has been the contention that through a rigorous application of phenomenology, a new mode of making moving imagery emerges, specifically one that gives particular emphasis to the placement of the camera and its associated technology in order to reveal the dynamic relationship between a perceiver and their environment in the twenty-first century.

Definition and Representation of Requirement Engineering/Management : A Process-Oriented Approach

Liaw, Judy-Audrey-Chui-Yik 11 May 2002 (has links)
Requirements are important in software development, product development, projects, processes, and systems. However, a review of the requirements literature indicates several problems. First, there is confusion between the terms ?requirements engineering? and ?requirements management.? Similarities and/or differences between the two terms are resolved through a literature review; resulting in comprehensive definitions of each term. Second, current literature recognizes the importance of requirements but offers few methodologies or solutions for defining and managing requirements. Hence, a flexible methodology or framework is provided for defining and managing requirements. Third, requirements methodologies are represented in various ways, each with their respective strengths and weaknesses. A tabular view and hybrid graphical view for representing the requirements process are provided.

Re-engineering the tender process at Tubular Track / Mattheus Casparus Maree

Maree, Mattheus Casparus January 2015 (has links)
In any organisation processes can be seen evolving throughout their lifecycle and play a deciding role in the efficiency of organisational activities. Tender processes are no different and with growing competitiveness and globalisation it has become the responsibility of managerial staff to ensure continuous improvement is applied to processes so organisational goals are consistently met and knowledge, talents and other success factors are institutionalised therein. The objective of this study was to perform an iteration of process re-engineering on the tender process within Tubular Track, so that a tender could be performed more efficiently and more competitively, and be more manageable. The investigation was carried out by means of a literature review and interviews. This was done to establish an accurate baseline from the current process and then re-engineer the system in its entirety. Verification of the investigation method was done through application of the PMBOK proven project management methods, while validation was done by comparison of processes through process improvement methodology principles as relationship. Process improvement and its management is a continuous procedure but because this study only focuses on the design of a new tender process for Tubular Track the conclusion that was made through literature application and comparison was that the newly designed process is expected to improve efficiency, manageability and time to complete. In the final conclusion stage recommendations were also made that re-engineering phases be planned and followed with corresponding risk and change management plans. Training needed for personnel so that implementation would be optimally applied and continuous improvement institutionalised would also need inspecting. / MIng (Development and Management Engineering), North-West University, Potchefstroom Campus, 2015

Desenvolvimento de um modelo de workflow que suporte as características fundamentais da realidade de processos de negócios / A workflow meta-model for supporting fundamental aspects of business process practice

Britto, Eduardo Carvalho de Souza January 2003 (has links)
Sistemas de workflow estão se tornando líderes de mercado na modelagem de regras de negócios das organizações. Contudo, eles ainda carecem de uma série de definições e padrões que sejam amplamente aceitos. Tais carências refletem-se nas técnicas atuais de modelagem de workflow, onde muitos conceitos existentes em um modelo são representados de forma completamente diferentes em outros ou, até mesmo, não existem. A partir de um levantamento realizado sobre os requisitos de modelagem de workflow, verificou-se que os modelos conceituais de workflow, hoje existentes, não atendem a todos os requisitos considerados essenciais para a modelagem da realidade dos processos de negócios. A identificação dos elementos de representação que devem existir em um modelo de processo para representar estes requisitos, o detalhamento das informações que devem ser levantadas durante a modelagem do processo para representar toda a realidade dos processos de negócio e o desenvolvimento de um modelo de processos que apresente estes elementos de representação são o objeto desta dissertação de mestrado. / Workflow systems are becoming the most important tools for business rules modeling. However, workflow systems still lack widely accepted definitions and standards. This is reflected in the difference among existing workflow modeling techniques. Many times the same modeling concept is represented in very different ways in different models or is even absent in some of them. Workflow modeling requirements were evaluated and it became clear that the existing workflow conceptual models do not offer all the essential resources needed to model real business processes. The main goals of this work are: to identify the representation elements needed to express such requirements; to define all the information that has to be gotten during process modeling in order to represent to whole business process reality; to propose a process model that presents these representation elements.

Iterchanging Discrete Event Simulationprocess Interaction Modelsusing The Web Ontology Language - Owl

Lacy, Lee 01 January 2006 (has links)
Discrete event simulation development requires significant investments in time and resources. Descriptions of discrete event simulation models are associated with world views, including the process interaction orientation. Historically, these models have been encoded using high-level programming languages or special purpose, typically vendor-specific, simulation languages. These approaches complicate simulation model reuse and interchange. The current document-centric World Wide Web is evolving into a Semantic Web that communicates information using ontologies. The Web Ontology Language – OWL, was used to encode a Process Interaction Modeling Ontology for Discrete Event Simulations (PIMODES). The PIMODES ontology was developed using ontology engineering processes. Software was developed to demonstrate the feasibility of interchanging models from commercial simulation packages using PIMODES as an intermediate representation. The purpose of PIMODES is to provide a vendor-neutral open representation to support model interchange. Model interchange enables reuse and provides an opportunity to improve simulation quality, reduce development costs, and reduce development times.
