The goal of this study is to dynamically simulate a turning-centre main spindle system utilizing the systems receptance coupling technique determine system's first three resonant frequencies in event transverse vibrations. findings are then confirmed using finite element ANSYS software. significance analysing described that it can be utilized optimize terms resonance for improved performance vi...

In view of the high investment and tooling cost of a CNC machining centre, the cutting and idle times should be optimised by considering the tool consumption and the non-machining time cost components. In this paper, we propose a detailed mathematical model for the operation of a CNC machine tool which includes the system characterisation, the cutting conditions and tool life relationship, and ...

Normally a decision support system is build to solve problem where multicriteria decisions are involved. The knowledge base is the vital part of the decision support containing the information or data that is used in decision-making process. This is the field where engineers and scientists have applied several intelligent techniques and heuristics to obtain optimal decisions from imprecise info...

The design of a CBR system involves the use of similarity metrics. For many applications, various functions can be adopted to compare case features and to aggregate them into a global similarity measure. Given the availability of multiple similarity metrics, the designer is hence left with two options in order to come up with a working system: Either select one similarity metric or try to combi...

This paper focuses on the integration of GIS and an extension of the analytical hierarchy process (AHP) using quantifier-guided ordered weighted averaging (OWA) procedure. AHP_OWA is a multicriteria combination operator. The nature of the AHP_OWA depends on some parameters, which are expressed by means of fuzzy linguistic quantifiers. By changing the linguistic terms, AHP_OWA can generate a wid...

The selection of students is a complex decision making process, in which multiple selection criteria often need to be considered and where subjectiveness and imprecision are usually present, resulting that fuzzy and imprecise data should be used. This paper formulates the student selection process as a multicriteria decision analysis problem, concretely as a ranking problem, by using the ELECTR...

This paper presents a multicriteria decision model for selecting a portfolio of information system (IS) projects, which integrates strategic and organizational view within a multicriteria decision structure. The PROMETHEE V method, based on outranking relations is applied, considering the c-optimal concept in order to overcome some scaling problems found in the classical PROMETHEE V approach. T...

Triple C' is a new visual interactive system which supports the exploration of multicriteria decisions. The novelty of this system consists in an overall utilization of Visual Interaction for supporting ail the information processing activities related to the task of incrementally defining and analyzing a multicriteria decision situation. Departing from traditional approaches in the MCDM field,...

The article proposes concept of solution development for diagnosis and control of real-time cutting tool in for edge cutting machining. The functional model of a diagnosis subsystem based on data reading from sensors of various types established in a cutting zone is developed. Algorithms of subsystem accepted signals processing and averaging, allowing define condition of cutting tool with defin...

The real-time online decision support system RODOS provides support throughout all phases of a nuclear or radiological emergency in Europe. The multicriteria decision support tool Web-HIPRE has been integrated into RODOS for a transparent evaluation of long-term measures, taking into account the preferences of a decision making team. However, a decision making process in practice is subject to ...
