Modelling rail track deterioration and maintenance: current practices and future needs

As commercialisation and privatisation of railway systems reach the political agendas in a number of countries, including Australia, the separation of infrastructure from operating business dictates that track costs need to be shared on an equitable basis. There is also a world-wide trend towards increased pressures on rail track infrastructure through increases in axle loads and train speeds. Such productivity and customer service driven pressures inevitably lead to reductions in the life of track components and increases in track maintenance costs. This paper provides a state-of-the-art review of track degradation modeling, as well as an overview of track maintenance decision support systems currently in use in North America and Europe. The essential elements of a maintenance optimisation model currently under development are also highlighted

The process of researching animal health and welfare planning

’Minimising medicine use in organic dairy herds through animal health and welfare planning’, ANIPLAN, is a CORE-Organic project which was initiated in June 2007. The main aim of the project is to investigate active and well planned animal health and welfare promotion and disease prevention as a means of minimising medicine use in organic dairy herds. This aim will be met through the development of animal health and welfare planning principles for organic dairy farms under diverse conditions based on an evaluation of current experiences. This also includes application of animal health and welfare assessment across Europe. In order to bring this into practice the project also aims at developing guidelines for communication about animal health and welfare promotion in different settings, for example, as part of existing animal health advisory services or farmer groups such as the Danish Stable School system and the Dutch network programme. The project is divided into the following five work packages, four of which comprise research activities with the other focused on coordination and knowledge transfer, through meetings, workshops and publications. The content of this set of workshop proceedings reflects the fact that the workshop in Fokhol in Norway was held at a relatively early stage with regard to certain joint activities and methodological development. Training in animal welfare assessment had taken place for the first time in the project a couple of months previous to this workshop, and the results in terms of inter-observer reliability are presented by the organisers of this training workshop, Solveig March, Lisi Gratzer and Jan Brinkmann and their supervisor Christoph Winckler. This forms a good background for a reliable data collection in all countries. A presentation from a newly employed Ph.D. student linked to the ANIPLAN project, Lindsay Kay Whistance, gives insight into the study of defecation behaviour in dairy cattle. Although not directly part of the ANIPLAN studies, the presentation is particularly relevant to the considerations regarding animal welfare in housed and outdoor systems. Gidi Smolders from the Netherlands presented a paper about a Dutch farmer group initiative with a strong element of farmer ownership. Mette Vaarst contributes with a paper on farmer learning and empowerment in groups, with a background of Danish experiences with the so-called ‘Stable Schools’. Two papers by Roderick and Vaarst reflect the workshop discussions about research methodologies and the various contexts and conditions for farmer group work. These two papers demonstrate the complexity of the research requirements when conducting a trans-national and cross-disciplinary research project with many stakeholders

Actors and factors - bridging social science findings and urban land use change modeling

Recent uneven land use dynamics in urban areas resulting from demographic change, economic pressure and the cities’ mutual competition in a globalising world challenge both scientists and practitioners, among them social scientists, modellers and spatial planners. Processes of growth and decline specifically affect the urban environment, the requirements of the residents on social and natural resources. Social and environmental research is interested in a better understanding and ways of explaining the interactions between society and landscape in urban areas. And it is also needed for making life in cities attractive, secure and affordable within or despite of uneven dynamics.\ud The position paper upon “Actors and factors – bridging social science findings and urban land use change modeling” presents approaches and ideas on how social science findings on the interaction of the social system (actors) and the land use (factors) are taken up and formalised using modelling and gaming techniques. It should be understood as a first sketch compiling major challenges and proposing exemplary solutions in the field of interest

A practitioner's guide to 'Imagine', the systemic and prospective sustainability analysis

The purpose of the Mediterranean Action Plans Coastal Area Management Programme is to help Mediterranean countries implement a sustainable management process for their coastal areas. This in particular implies thinking collectively about possible futures by taking into account past developments and the present situation of the area in question. To do so and right from the very start, the Blue Plan has assisted teams involved in the CAMPs to use the systemic and prospective approach so as to highlight priorities, forecast negative developments and suggest action to be taken to establish sustainable development in the Mediterranean's coastal areas. What do we mean by sustainable development? The Blue Plan adheres to a definition that is a blend of what you find in the Bruntland Report and at the FAO, 'sustainable development is one that respects the environment, is technically appropriate, economically viable and socially acceptable, making it possible to meet the needs of present generations without jeopardising the ability of future generations to meet their own needs'. In this framework the 'Imagine' analysis of systemic and prospective sustainability now proposes a set of tools and methods (a methodological corpus) to describe, assess and examine the level of sustainability of an eco-socio system in the past, present and future by means of indicators and a participatory process that considers local actors to be experts at their level

Planning for better animal health and welfare, Report from the 1st ANIPLAN project workshop, Hellevad, October 2007

’Minimising medicine use in organic dairy herds through animal health and welfare planning’, ANIPLAN, is a CORE-Organic project which was initiated in June 2007. The main aim of the project is to investigate active and well planned animal health and welfare promotion and disease prevention as a means of minimising medicine use in organic dairy herds. This aim will be met through the development of animal health and welfare planning principles for organic dairy farms under diverse conditions based on an evaluation of current experiences. This also includes application of animal health and welfare assessment across Europe. In order to bring this into practice the project also aims at developing guidelines for communication about animal health and welfare promotion in different settings, for example, as part of existing animal health advisory services or farmer groups such as the Danish Stable School system and the Dutch network programme. The project is divided into the following five work packages, four of which comprise research activities with the other focused on coordination and knowledge transfer, through meetings, workshops and publications. These proceedings represent our first results in terms of presented papers and discussions at our first project workshop in Hellevad Vandmølle as well as a review of Animal Health Planning in UK. The content of the workshop proceedings reflect the aim and starting points of all work packages, both in terms of analyses prior to the workshop, and developments during the workshop emanating from group work. Besides a general introduction to the project and the ideas of the project, Christoph Winckler provides an overview of the use of animal based parameters based on the results of the WelfareQuality project. Christopher Atkinson and Madeleine Neale presented concepts, principles and the practicalities of Animal Health Planning and Animal Health Plans based on UK experiences. Pip Nicholas from The University of Wales, Aberystwyth produced a report reviewing the current use of animal health and welfare planning. The entire document is included in these workshop proceedings. This was supplemented through presentations from all countries regarding animal health and welfare planning processes and research. These are summarised together with the concepts developed through dialogue at the workshop in the paper by Nicholas, Vaarst and Roderick. Finally, the Danish Stable School principles were presented by Mette Vaarst followed by discussion on different approaches of communication in farmer groups and at the individual level between farmers and advisors. One important outcome from this workshop is a set of preliminary principles for a good health planning process. We concluded through group discussions followed by a plenary session that a health planning process should aim at continuous development and improvement, and should incorporate health promotion and disease handling, based on a strategy where the current situation is evaluated and form basis for action, which is then reviewed in a new evaluation. It is important that any health plan is farm specific and based on farmer ownership, although an external person(s) should be involved, as well as external knowledge. The organic principles should form the framework for any action (meaning that a systems approach is needed), and the plan should be written. The good and positive aspects on each farm – things that other farmers potentially can learn from. The work and studies in dairy farms within the project will be based on these principles and comprise evaluation and review using animal based parameters as well as finding ways of communication with farmers about animal health and welfare

Progress in AI Planning Research and Applications

Planning has made significant progress since its inception in the 1970s, in terms both of the efficiency and sophistication of its algorithms and representations and its potential for application to real problems. In this paper we sketch the foundations of planning as a sub-field of Artificial Intelligence and the history of its development over the past three decades. Then some of the recent achievements within the field are discussed and provided some experimental data demonstrating the progress that has been made in the application of general planners to realistic and complex problems. The paper concludes by identifying some of the open issues that remain as important challenges for future research in planning
