Shared Vision Planning (SVP) is a collaborative approach to water (resource) management that combines three practices: (1) traditional water resources planning; (2) structured participation of stakeholders; (3) (collaborative) computer modeling and simulation. The authors argue that there are ample opportunities for learning and innovation in SVP when we look at it as a form of Policy Analysis (PA) in a multi-actor context. SVP faces three classic PA dilemmas: (1) the role of experts and scientific knowledge in policymaking; (2) The design and management of participatory and interactive planning processes; and (3) the (ab)use of computer models and simulations in (multi actor) policymaking. In dealing with these dilemmas, SVP can benefit from looking at the richness of PA methodology, such as for stakeholder analysis and process management. And it can innovate by incorporating some of the rapid developments now taking place in the field of (serious) gaming and simulation (S&G) for policy analysis. In return, the principles, methods, and case studies of SVP can significantly enhance how we perform PA for multi-actor water (resource) management. © 2010 ASCE.

Organizations, be it public or private, have to ensure that their operations are complying with various governmental regulations, otherwise they may suffer from law suits and financial losses, or they may even not be allowed to operate (e.g., in case of repeated violations). Therefore, organizations need to have a clear understanding of all the relevant regulations and verify that their business processes are designed and performed in a desired way. However, regulations can be fairly complex in terms of the conditions, targets, and scopes they refer to. Moreover, when considering a set of regulations, the possibility of interrelationships between them brings added complexity to compliance checking. Thus, ensuring regulatory compliance is not only labor and time consuming but also complex. In this paper, we propose a consistency and compliance checker framework (CCCF) that considers sets of interrelated regulations and aims at providing automated supports for organizations to analyze and verify their regulatory compliance. More specifically, CCCF takes legal regulations and business processes as inputs and provides the results of whether the regulations are consistent, whether the business processes are compliant with the regulations, and which business operations need to be adjusted in case of non-compliance. To validate our approach, we use a case study of customs declaration in international trade. © 2014, Springer-Verlag London.

Using ethnography to build agent-based models may result in more empirically grounded simulations. Our study on innovation practice and culture in the Westland horticulture sector served to explore what information and data from ethnographic analysis could be used in models and how. MAIA, a framework for agent-based model development of social systems, is our starting point for structuring and translating said knowledge into a model. The data that was collected through an ethnographic process served as input to the agent-based model. We also used the theoretical analysis performed on the data to define outcome variables for the simulation. We conclude by proposing an initial methodology that describes the use of ethnography in modelling. © 2015 JASSS.

To explore the space between the theories of the Diffusion of Innovations and Universal Darwinism, we first examine a case study of the history of the greenhouse horticulture sector of the Netherlands, comparing and contrasting the narrow focus of Diffusion of Innovations and the wider focus of Universal Darwinism. We then build an agent-based model using elements of both in order to test how well the Diffusion of Innovations theory holds up when some of its simplifications are removed. Results show that the single, simple pattern prominent in Diffusions of Innovations theory does emerge, but that it is only one of several patterns and that it does not behave precisely as expected. Results also show agent properties, such as stubbornness or innovativeness, can be surprisingly complex, as when stubbornness shows an advantage in the long term, while innovativeness was beneficial to the network but not to the innovator. While the Diffusion of Innovations theory is simple and can easily guide policy decisions, this paper shows that adding complexity to place diffusions inside a larger evolutionary context results in more realistic analysis and can help policy-makers to achieve challenging goals amidst modern economic and political challenges.

Environmental Innovation and Societal Transitions | Year: 2013

To understand the consequences of the E.U. ban on incandescent lamps, an agent-based model is developed in which consumer behaviour regarding purchase of lamps is simulated. Consumers are modelled as having heterogeneous and dynamic preferences on lamps. Development of preferences depends on memory and perceptions, as well as interaction in a social network structure. Lighting technology is modelled to cover many different lamps and technologies. The results indicate that the ban on bulbs will be effective in realising an energy efficient sector. Although the ban on bulbs causes a spike in consumers' purchases, the consequent benefits of energy saving outweigh the additional costs of purchasing these lamps. Introducing a tax on incandescent lamps would also be effective given a sufficiently high tax level and could be income-neutral with respect to purchasing lamps. A possible penetration of halogen lamps may hamper the transition to lower electricity consumption. © 2013 Elsevier B.V. All rights reserved.

Research on socio-technical systems, to which an enterprise, its organization, business processes, and supporting ICT belong, has been witnessing a resurging interest. Many research initiatives have been launched for the development of concepts, methods, and tools for the analysis and design of the enterprise structure, function, and processes, and for identification of actor roles and responsibilities in a consistent manner. One of the main drivers pushing research into this direction is the changing environment in which enterprises are functioning. In view of these trends, adoption of modeling and simulation, as two complementary tools for design, redesign, and improvement of enterprises, is becoming a standard practice. Especially in the face of ever evolving and changing business environment. In this article, we explain the relationship between enterprise, organization, and business processes on the one hand, and the relevance of modeling and simulation as a method in enterprise and organizational study. © 2010 Springer-Verlag.

Sustainability policy in the early 2000s is based on and therefore influenced by scientific literature on 'transition'. The importance of this link has inspired the authors to explore the structure of cooperating authors and citation networks in the field. In order to understand 'transition' literature, we compare it with an alternative term for change, 'transformation', which is also used in the context of socio-technical shifts towards sustainability. We expose the different structures of these fields with an overview of keywords, key references, key authors, and the coherence between references and authors. By analysing co-author and citation networks, we find large differences in these groups of documents. The transition literature is characterised by a large network of directly and indirectly cooperating authors with clear clusters; transformation literature contains smaller author networks. Key transition authors are predominantly Dutch. They repeatedly write together and cite each other's work. The transition literature is tightly knit with high degrees of internal references and a clearly distinguishable core. Transformation literature has fewer connections between authors and articles. The connecting articles, each with many global citations, form its basis. This analysis can be used as a step to continue the debate on the role of transition and transformation literature in sustainability and renewable energy policy. The transformation literature teaches us that older streams of thought are still relevant and may be used as 'glue' for linking change with respect to sustainable energy to wider developments. Rediscovering existing literature in new combinations may lead to promising new views on sustainable energy. © 2013 The Authors.
