Events in system analysis is not a new concept. It has been used in Petri nets, stochastic modeling, etc. However, there are new opportunities that come from the lage amount of data that is stored in various databases. In this paper we will focus on formulating the event mining tasks that consider observations of the system as well as internal and external events

Views or opinions expressed herein do not necessarily represent those of the Institute, its National Member Organizations, or other organizations supporting the work.- ii-Foreword Practically all important decisions involve analysis of several (or even many), typically conflicting, criteria. Analysis of trade-offs between criteria is difficult because such trade-offs for most problems are practically impossible to be defined a-priori even by analysts experienced in Multi-Criteria Analysis (MCA). Therefore the trade-offs emerge during an interactive MCA which actually supports a learning process about the trade-offs. How-ever, in some situations an objective MCA is desired, i.e., the trade-offs are elicited rather from the data than from preferences of actual decision-makers. Therefore effective MCA methods are important for actual support of decision-making processes, esp...

Examples of such situations are, on the one hand, managerial decisions influencing many stakeholders, when an aggregation of preferences of stakeholders is impossible. On the other hand, such situations occur also in event detection; e.g., when automatically detecting a case of fire, we should not make decisions based on subjective, personal preferences. We shall call the problem of supporting decisions in such a case the problem of objective classification (treating problem of ranking as a special case with single...

Most of them require complex specification of preferences. Therefore, they are not applicable for problems with numerous alternatives and/or criteria, where preference specification by the decisin makers can hardly be done in a way acceptable for small problems, e.g., for pair-wise comparisons. In this paper we describe several new methods implemented for a real-life application dealing with multi-criteria analysis of future energy technologies. This analysis involves large numbers of both alternatives and criteria. Moreover, the analysis was made by a large number of stakeholders without expeience in analytical methods. Therefore a simple method for interactive preference specification was condition for the analysis. The paper provides overview of several of new methods based on diverse concepts developed for multicriteria analysis, and summarizes a comparison of methods and exp...

Methods that might be applied include reference point approaches, particularly if appropriately modified, equitable aggregation approaches and special hierarchical aggregation schemes. The paper presents descriptions and necessary modifications of such methods, together with associated concepts of objective versus subjective decision selection, compensatory versus non-compensatory criteria, preservation of Pareto-nondominance in hierarchical aggregation, etc. Examples show that methods effective in most difficult cases are based on reference point approaches combined with equitable aggregation ...

MCA in its currently available version supports analysis of a set of discrete alternatves, defined either interactively or through a prepared file. Each alternative is characterized by several attributes (indicators) that serve for specification of criteria. MCA has been designed for problems having large numbers of alternatives and of criteria. However, it can also be used for problems with small numbers of criteria and/or alternatives. The report is composed of two main parts. The first one provides an overview of the MCA and summarize the methodology of multiple criteria analysis implemented in the MCA. The second part consists of the step-by-step detailed tutorial to the MCA organized into three stages corresponding to (1) basic funtions of the MCA, (2) specification of problems, instances...
