Once the model f tted (adjusted) to data, it remains to be validated before its successful application to solve real-life problems. The notion of validating a given model covers a wide enough range of issues to be considered. Thus, by “validation” we understand the level of the practical value of the model in explaining a particular phenomenon, assessing both its similarity to the prototype and its effectiveness in a straight application to a given situation. We speak of validating the model: • in the model development, the adjusted model revealing new aspects concerning data; • in the testing phase, when new data are collected and used to optimize the proposed model; • in the practical application stage, when procedures for “monitoring” are introduced to check whether the originally proposed model is effective or not in “live” conditions.

A typical example of such data refers to data stored in a customer database, in which each transaction is a collection of goods purchased by a customer in a single visit to the supermarket (market basket data) -see Fig. 5. Another type of such transactional data refers to data concerning the Web usage. We illustrate below examples of such ordered data -see Fig.

In the f rst case, for instance, the idea is to equip these intervention vehicles with equipment and devices that are frequently used in different types of interventions, so that, when there is a new application for a particular intervention, the utility vehicle is properly equipped for intervention, saving time and fuel needed to ‘repair’ the lack of resource management. In this case, association rules are identif ed by processing the data referring to the type of devices and parts used in previous interventions in order to address various issues arising on the spot.
