biological sciences rely on models. This simple observation comes as no surprise to anyone who has either participated in or thought about biological research.

The complexity of the modelled biological systems and the growing number and size of the models calls for computer support for modelling and simulation in Systems Biology. This computer support has to be based on formal representations of relevant knowledge fragments. In this paper we describe different functional aspects of dynamic models. This description is conceptually embedded in our &quot;meaning facets&quot; framework which systematises the interpretation of dynamic models in structural, functional and behavioural facets. Here we focus on how function links the structure and the behaviour of a model. Models play a specific role (teleological function) in the scientific process of finding explanations for dynamic phenomena. In order to fulfil this role a model has to be used in simulation experiments (pragmatical function).

Biological system dynamics is basically understood by physico-mathematical models which gives the basics of the atomic/molecular interaction in living nature. The moment of the object in universe either with respect to time or space is made under the physico- mathematics. To better understand a particular dynamical system, it is often of interest to determine whether the system is caused by static subsystem, deterministic subsystems stochastic subsystems, or all. Alternatively, one can use methods that measure the complexity in a particular system which seldom make assumptions about a particular system, such as assuming the presence of stationarity. Additionally, mathematical and computational modelling techniques can be used to test different hypothesis about the dynamics of biological systems.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Models Of System Biology","attachmentId":26684528,"attachmentType":"pdf","work_url":"https://www.academia.edu/1885413/Models_Of_System_Biology","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/1885413/Models_Of_System_Biology"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="3" data-entity-id="68853874" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/68853874/I_INTRODUCTION_HE_aim_of_a_biological_model_is_to_understand_the_integrated_structure_and_behavior_of_complex_biological_systems_as_a_function_of_the_underlying_molecular_networks_to_achieve_simulation_and_forecast">I.

Therefore, we must consider the biological models that are used to acquire these data from an epistemological point of view. This article introduces three elements of this view: (i) we reviewed the major concepts and the axioms of the systemic paradigm; (ii) we considered their relevance for the modelling of the biological functions within the framework of an intracellular signalling process; (iii) we present an operational input founded on this methodological viewpoint to illustrate the coherence of a theoretical framework and the use of its formalism for the description and the representation of biological activities. This formalism will guide the modelling and the interpretation of molecular interactions in terms of organisational operations producing and transforming the genetic information; thus, providing a better understanding of the complex relationship between the generation, the circulation and the computation of information when biological systems are set up.

Une avancée dans le domaine de la conception des systèmes d'information pour l'exploitation des données de génomique fonctionnelle nécessite une discussion attentive des concepts de gène et de fonction, et donc une réflexion épistémologique sur les modèles biologiques à l'aide desquels sont établis ces systèmes d'information. Dans cet article, nous avons introduit les éléments de cette réflexion suivant trois axes : (i) un axe conceptuel considère les concepts majeurs et les axiomes du paradigme systémique ; (ii) leur pertinence pour la modélisation des fonctions biologiques est examinée dans le cadre d'un processus de signalisation intracellulaire ; (iii) une entrée opératoire, fondée sur cette réflexion méthodologique, illustre la cohérence apportée par un cadre théorique argumenté et l'utilisation de son formalisme pour la description et la représentation des activités biologiques. Ce formalisme conduit à interpréter le traitement des processus moléculaires en termes d'opérations organisationnelles produisant et transformant l'information génétique et à approfondir l'intelligibilité de la génération, de la circulation et du calcul de l'information dans la mise en place des organisations biologiques.

Philosophical debates has focused on several areas of discussion. First, the term ‗model' is applied to a bewildering array of objects in biology from mathematical structures, graphical displays, computer simulations, to concrete organisms. Each of these objects seems so different it raises the question of whether there is some one thing which is a model. Philosophers are investigating whether a unifying account of models can be found. Second, biologists rarely have fundamental theories as in physics and chemistry, but do have a variety of models. Many philosophers and biologists have suggested that biological theories are nothing more than a collection or family of models. Third, models are traditionally evaluated by their statistical fit to data or their explanatory power. However, biological models are highly idealizedliterally falsewhich can undercut their empirical adequacy and explanatory worth. As a result, biological models are often evaluated for the heuristic functions possibly unrelated to empirical adequacy and truth.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Models in biology","attachmentId":28291163,"attachmentType":"pdf","work_url":"https://www.academia.edu/1956627/Models_in_biology","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/1956627/Models_in_biology"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="6" data-entity-id="17897775" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/17897775/Some_questions_related_to_modeling_in_cellular_biology">Some questions related to modeling in cellular biology</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="37812366" href="https://independent.academia.edu/IvanKupka">Ivan Kupka</a></div><p class="ds-related-work--metadata ds2-5-body-xs">Journal of Fixed Point Theory and Applications, 2010</p><p class="ds-related-work--abstract ds2-5-body-sm">Keywords.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Some questions related to modeling in cellular biology","attachmentId":39768717,"attachmentType":"pdf","work_url":"https://www.academia.edu/17897775/Some_questions_related_to_modeling_in_cellular_biology","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/17897775/Some_questions_related_to_modeling_in_cellular_biology"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="7" data-entity-id="86830427" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/86830427/Qualitative_and_semi_quantitative_systems_approaches_to_complex_systems_modelling_Intuitive_and_flexible_models_of_biological_systems_A_thesis_submitted_in_partial_fulfilment_of_the_requirements_for_the_degree_of_Doctor_of_Philosophy_at_Lincoln_University">Qualitative and semi quantitative systems approaches to complex systems modelling – Intuitive and flexible models of biological systems : A thesis submitted in partial fulfilment of the requirements for the degree of Doctor of Philosophy at Lincoln University</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="210520211" href="https://independent.academia.edu/mohammadalsharaiah">mohammad alsharaiah</a></div><p class="ds-related-work--metadata ds2-5-body-xs">2018</p><p class="ds-related-work--abstract ds2-5-body-sm">Biological systems such as cell cycle are complex systems consisting of an enormous number of elements. These elements interact in ways that produce nonlinear and complex systems behaviour such as oscillations. A number of modelling approaches have been used to explain these kinds of systems; they are classified into four classes (continuous, discrete, stochastic and hybrid). Ordinary Differential Equations (ODEs) are used to mimic the continuous dynamic behaviour of system components, while discrete models can simulate the biological elements as straightforward binary variables providing a qualitative view of system behaviour. Stochastic models are used to model the effect of noise in biological systems. Combined methods together introduce hybrid models to cover the limitations of individual models and take advantage of their strengths. This study introduces a series of advanced models with increasing resolution from discrete to continuous in a systematic way to model the mammalian...</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Qualitative and semi quantitative systems approaches to complex systems modelling – Intuitive and flexible models of biological systems : A thesis submitted in partial fulfilment of the requirements for the degree of Doctor of Philosophy at Lincoln University","attachmentId":91197089,"attachmentType":"pdf","work_url":"https://www.academia.edu/86830427/Qualitative_and_semi_quantitative_systems_approaches_to_complex_systems_modelling_Intuitive_and_flexible_models_of_biological_systems_A_thesis_submitted_in_partial_fulfilment_of_the_requirements_for_the_degree_of_Doctor_of_Philosophy_at_Lincoln_University","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/86830427/Qualitative_and_semi_quantitative_systems_approaches_to_complex_systems_modelling_Intuitive_and_flexible_models_of_biological_systems_A_thesis_submitted_in_partial_fulfilment_of_the_requirements_for_the_degree_of_Doctor_of_Philosophy_at_Lincoln_University"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="8" data-entity-id="17130573" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/17130573/Understanding_the_Dynamics_of_Biological_Systems">Understanding the Dynamics of Biological Systems</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="471684" href="https://ircam.academia.edu/JeanLouisGiavitto">Jean-Louis Giavitto</a></div><p class="ds-related-work--metadata ds2-5-body-xs">2011</p><p class="ds-related-work--abstract ds2-5-body-sm">Systems biology aims at integrating processes at various time and spatial scales into a single and coherent formal description to allow analysis and computer simulation. In this context, we focus on rule-based modeling and its integration in the domain-specific language MGS. Through the notions of topological collections and transformations, MGS allows the modeling of biological processes at various levels of description. We validate our approach through the description of various models of a synthetic bacteria designed in the context of the iGEM competition, from a very simple biochemical description of the process to an individual-based model on a Delaunay graph topology. This approach is a first step into providing the requirements for the emerging field of spatial systems biology which integrates spatial properties into systems biology.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Understanding the Dynamics of Biological Systems","attachmentId":42312964,"attachmentType":"pdf","work_url":"https://www.academia.edu/17130573/Understanding_the_Dynamics_of_Biological_Systems","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/17130573/Understanding_the_Dynamics_of_Biological_Systems"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="9" data-entity-id="69148802" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/69148802/Published_in_2007_in_Modeling_Biology_Structures_Behaviors_Evolution">Published in 2007 in: Modeling Biology: Structures, Behaviors, Evolution</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="41074" href="https://asu.academia.edu/ManfredLaubichler">Manfred Laubichler</a></div><p class="ds-related-work--metadata ds2-5-body-xs">2012</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Published in 2007 in: Modeling Biology: Structures, Behaviors, Evolution","attachmentId":79355594,"attachmentType":"pdf","work_url":"https://www.academia.edu/69148802/Published_in_2007_in_Modeling_Biology_Structures_Behaviors_Evolution","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/69148802/Published_in_2007_in_Modeling_Biology_Structures_Behaviors_Evolution"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div></div></div><div class="ds-sticky-ctas--wrapper js-loswp-sticky-ctas hidden"><div class="ds-sticky-ctas--grid-container"><div class="ds-sticky-ctas--container"><button class="ds2-5-button js-swp-download-button" data-signup-modal="{"location":"continue-reading-button--sticky-ctas","attachmentId":41203864,"attachmentType":"pdf","workUrl":null}">See full PDF</button><button class="ds2-5-button ds2-5-button--secondary js-swp-download-button" data-signup-modal="{"location":"download-pdf-button--sticky-ctas","attachmentId":41203864,"attachmentType":"pdf","workUrl":null}"><span class="material-symbols-outlined" style="font-size: 20px" translate="no">download</span>Download PDF</button></div></div></div><div class="ds-below-fold--grid-container"><div class="ds-work--container js-loswp-embedded-document"><div class="attachment_preview" data-attachment="Attachment_41203864" style="display: none"><div class="js-scribd-document-container"><div class="scribd--document-loading js-scribd-document-loader" style="display: block;"><img alt="Loading..." src="//a.academia-assets.com/images/loaders/paper-load.gif" /><p>Loading Preview</p></div></div><div style="text-align: center;"><div class="scribd--no-preview-alert js-preview-unavailable"><p>Sorry, preview is currently unavailable.
