%X Reaching a decision when multiple, possibly conflicting, criteria aretaken into account is often a difficult task. This normally requires the intervent ion ofan analyst to aid the decision mak er in following a clear methodology with respectto the steps that need to be taken, as well as the use of different algorithms andsoftware tools. Most of these tools focus on one or a small number of algorithms,some are difficult to adapt and interface with other tools, while only a few belong todynamic communities of contributors allowing them to expand in use and func-tionality. In this paper, we address these issues by proposing to use the R statisticalenvironment and the MCDA package of decision aiding algorithms and tools. Thispackage is meant to provide a wide range of MCDA algorithms that may be used byan analyst to tailor a decision aiding process to their needs, while the choice of Rtakes advantage of the yet poorly explored opportunity to interface data analysis anddecision aiding. We additionally demonstrate the use o f this tool on a practicalapplication following a well -defined decision aiding process.

%X In this presentation we recall the main reasons why a new version was needed for XMCDA, and the work that has been done until the XMCDA v3 is released. We then present all its benefits, and the new Java reference library which has been developped to support both the XMCDA v3, and XMCDA v2 as well to support the transtional period. We conclude by a demonstration on how it is used to develop algorithmic components (software) that can inter-operate with each other in the Decision Deck Web-Services & diviz eco-system, especially by using the new software skeleton generator based on the XMCDA 3 reference library for the languages Java, Python and R.

%X In this presentation we highlight diviz, a platform for designing, processing and sharing Multicriteria Decision Aiding (MCDA) algorithms and experiments. One of its main features is the possibility to design complex MCDA algorithms by combining elementary calculation components via an intuitive graphical user interface. The target user community of diviz reaches from researchers to teachers, students and MCDA analysts solving real-life decision problems. The diviz software also eases the comparison of results produced by different algorithms on the same decision problem instance and facilitates the dissemination of MCDA methods and experiments.

%X In this chapter, we illustrate how the MCDA process can be supported by the use of a decision aiding software called diviz. The diviz workbench allows to build, execute and share complex workflows of MCDA algorithms, and as such, is a convenient tool to help the analyst in the decision aiding process. We start by a presentation of diviz, before switching to the detailed description of a didactic MCDA process, based on a classical example from the MCDA literature. We show how each major step of this process can be backed up by diviz, and how the software can help to build the final recommendation.

%X Up to recently, the processing of a decision problem via several Multiple Criteria Decision Aiding (MCDA) programs required to write the data in various formats. This chapter presents XMCDA, an initiative of the Decision Deck Consortium, which is a standard data model enabling to encode classical concepts from MCDA in XML. Among other things, it eases the analysis of a problem instance by various MCDA techniques compatible with XMCDA without requiring data conversions and it simplifies the sequencing of MCDA algorithms for the resolution of complex decision problems.

%X An assessment of a method that enabled to design a data warehouse logical model in accordance with the business viewpoint of an enterprise showed that not considering the physical viewpoint when designing the data warehouse was the major flaw of the method, and that a tool has to be proposed to generate the data warehouse data instances when business viewpoints or input databases are modified. Our contribution is hence the adaptation of the logical design method of the data warehouse to a physical design method. Moreover, a tooling of this new physical design method and a tooling of the data warehouse physical data instantiation are proposed in this paper. The tools are based on the model driven engineering approach and its associated environment such as a model transformation language.

%X The design of a data warehouse from the databases of the enterprise is a very important feature to specify the strategy of this enterprise. The strategy is indeed deduced from the enterprise results stored in its databases. The business processes of the enterprise have moreover to be consistent with this strategy. We propose then a rule-based data warehouse design method. The rules target first a data model alignment with respect to the business processes model. The other rules are featured by a data pattern proposing a solution for the data warehouse design in relation to the categorization of the data. The pattern is compliant with the life-cycle of a business process instance. This pattern is moreover relevant for the specification of the queries concerning the data warehouse. This data warehouse design method based on rules is experimented from two epidemiological databases building up for medical research.

%X Multiple Criteria Decision Aid (MCDA) algorithms help making the right decision. However, choosing and using an MCDA algorithm very often represents only a short and precise event of a much longer decision aid process. Moreover, this process involves multiple conflicting criteria and various stakeholders.In this work, we actually formalize a business process model of the MCDA process. Such a business process is a set of discrete activity steps, with associated computer and/or human operations, and rules governing the progression of the process through the various activity steps. The activitiesare supported/implemented by an Information System. This Information System consists, in this study, in (web-)services (via Service Oriented Architecture, SOA) which expose MCDA algorithms. We are also studying the alignment (i.e. the extent of correspondence) of models of this Information System (i.e. the MCDA services) with the MCDA process model. This alignment results, for each activity of the MCDA process, in an inventory of the services which fulfill it partially or totally. The analysis of this alignment improves the relevance and completeness of the definition of the MCDA services which realize the process, thus contributing towards guiding/automating the process.
