tract: ELECTRE II and III methods enjoy a wide acceptance in solving multi-criteria decision-making (MCDM) lems. Research results in this paper reveal that there are some compelling reasons to doubt the correctness of roposed rankings when the ELECTRE II and III methods are used. In a typical test we first used these ods to determine the best alternative for a given MCDM problem. Next we random...

The incorporation of preferences into Evolutionary Algorithms (EA) presents some relevant advantages, namely to deal with complex real-world problems. It enables focus on the search thus avoiding the computation of irrelevant solutions from the point of view of the practical exploitation of results (thus minimizing the computational effort), and it facilitates the integration of the DM’s expert...

We present ALARM (HierarchicAL AppRoach for AnoMaly Detection), a hierarchical approach for correlation and prioritization of alerts in distributed networks. The goal is to monitor, classify, correlate and assess a large number of alerts generated at spatially distributed sites on the Internet. The alerts correspond to anomalies and hence potential unknown threats. To facilitate our analysis, w...

The Electre language has been developed as a resuit of the expérience of the automatic control department in the implementation of the real time control applications. These applications consist of many tasks that are conditionally executed and interrupted according to some events 'occurences. We propose a language semantic and in particular that of its fundamental operators: parallelism of task...

Our work intends to verify reactive systems with event memorization speciied with the reactive language Electre. For this, we deene a particular behavioral model for Electre programs , Reactive Fiio Automata (RFAs), which is close to Fifo Automata. Intuitively, a RFA is the model of a reactive system which may store event occurrences that must not be immediately taken into account. We show that...

The ability of enterprise information systems, such as enterprise resource planning (ERP), manufacturing executive systems (MES) and customer relation management (CRM), to improve production and business performance are demanding more attention from enterprises, since increase in competitive advantages is a goal to be reached. Integration of all the information flowing through a company is a ke...

. ABC analysis is one of the most widely used techniques in inventory management to classify items into three ordered categories called A, B and C, where category A contains the most important items and category C includes the least important ones. The ABC classification of inventory items is based on their performance expressed by weighted scores. In this paper, a new ABC classification model ...

In this paper the authors carry out a multiple criteria evaluation of 40 characteristics of e-learning platforms, in order to find the most suitable to meet the needs of an e-learning course for higher schools with Agricultural and Forestry content. The evaluation data came from a Delphi survey method, where experts’ opinions are reflected. These data were introduced in ELECTRE III, a multi-cri...

Often decisions taken in organizations are made by a group of people, and in order to build a collective decision, the preferences of individuals must be considered. The two most useful approaches to aggregating individual preferences are the aggregation of individual judgments and the aggregation of individual priorities. This paper focuses on the latter approach and proposes a multicriteria g...
