Vrednovanje činitelja u procesu donošenja odluke o kupnji namještaja primjenom AHP metode

There are not many wooden products that consumers would buy on pure impulse. Their decision regarding the purchase of a product normally undergoes a process of consideration – the more expensive the product, the more thorough the consideration. The consumer buying decision process consists of five stages: need recognition, search for information, alternatives evaluation, purchase decision and post-purchase behaviour. A company must establish what is important for consumers in each stage of this process. On the basis of these findings, the company must define the measures to influence consumers in individual phases. In this study, the analytic hierarchy process was used to analyse the buying behaviour of potential furniture buyers. Slovenian and Croatian marketing experts were asked about the habits, requests and needs of furniture buyers. The results of the research can serve as useful information for companies producing wooden products in the formulation of successful marketing strategies.Ne postoji mnogo proizvoda od drva koje bi kupci kupili impulzivno, bez dodatnog poticaja i razmišljanja. Odluka potencijalnog kupca s obzirom na vrstu proizvoda obično prolazi kroz proces razmatranja, i to na način da je za skuplji proizvod razmatranje detaljnije. Proces donošenja odluke o kupnji nekog proizvoda ima pet faza: prepoznavanje potrebe, potraga za informacijom, vrednovanje alternativa, odluka o kupnji i ponašanje nakon kupnje. Tvrtka mora utvrditi što je njezinim potencijalnim kupcima (potrošačima) u svakoj fazi procesa donošenja odluke o kupnji važno. Na temelju toga, tvrtka mora odrediti mjere kojima će utjecati na potrošača u pojedinim fazama procesa razmatranja. Cilj ovog rada bio je vrednovati činitelje u procesu donošenja odluke o kupnji namještaja primjenom metode analitičkoga hijerarhijskog procesa (AHP). Vrednovanje pokazatelja navika, zahtjeva i potreba kupaca namještaja proveli su suradnici iz Slovenije i Hrvatske koji se bave istraživanjima i aktivnostima u području marketinga. Rezultati istraživanja mogu pomoći proizvođačima i/ili prodavačima namještaja u procesima definiranja uspješnih marketinških strategija

New group decision-making ARCAS approach based on the integration of the SWARA and the ARAS methods adapted for negotiations

Groups are generally considered to be more effective as compared to single individuals. The practical implementation of Operation Research methods in group negotiations needs simple contexts and clear cause-and-effect relationships easily discernible by everyone. This paper proposes a multi-criteria group decision-making approach allowing decision makers/experts involved in a negotiation process to better express and defend their preferences in the selection of the best alternative. In the proposed approach, the most appropriate alternative is the alternative with the largest number of appearances in the first position or in ranking lists, or the one determined based on negotiations of decision makers/experts. The proposed ARCAS approach is based on the use of the ARAS method, a new normalization procedure, and the SWARA method. In the proposed approach, each decision maker/expert involved in evaluation has an opportunity to set the preferred level of rating for each criterion used in such evaluation. Finally, a case study is presented in order to highlight the proposed approach. The obtained results confirm the usability and efficiency of the proposed approach

Decision-making under uncertainty – the integrated approach of the AHP and Bayesian analysis

In situations where it is necessary to perform a large number of experiments in order to collect adequate statistical data which require expert analysis and assessment, there is a need to define a model that will include and coordinate statistical data and experts’ opinions. This article points out the new integrated application of the Analytic Hierarchy Process (AHP) and Bayesian analysis, in the sense that the Bayes’ formula can improve the accuracy of input data for the Analytical Hierarchy Process, and vice versa, AHP can provide objectified inputs for the Bayesian formula in situations where the statistical estimates of probability are not possible. In this sense, the AHP can be considered as the Bayesian process that allows decision-makers to objectify their decisions and formalise the decision process through pairwise comparison of elements

AHP-group decision making based on consistency

The Precise consistency consensus matrix (PCCM) is a consensus matrix for AHP-group decision making in which the value of each entry belongs, simultaneously, to all the individual consistency stability intervals. This new consensus matrix has shown significantly better behaviour with regards to consistency than other group consensus matrices, but it is slightly worse in terms of compatibility, understood as the discrepancy between the individual positions and the collective position that synthesises them. This paper includes an iterative algorithm for improving the compatibility of the PCCM. The sequence followed to modify the judgments of the PCCM is given by the entries that most contribute to the overall compatibility of the group. The procedure is illustrated by means of its application to a real-life situation (a local context) with three decision makers and four alternatives. The paper also offers, for the first time in the scientific literature, a detailed explanation of the process followed to solve the optimisation problem proposed for the consideration of different weights for the decision makers in the calculation of the PCCM

An Evaluation of Indicators of Railway Intelligent Transportation Systems using the Group Analytic Hierarchy Process

Intelligent Transportation Systems (ITS) have a significant and promising role in the overall improvement of transport performances. However, in the absence of a set of key performance indicators (KPI), it is very difficult to evaluate ITS and the effects of their application objectively. Therefore, the first aim of the paper is to develop an appropriate KPIs for assessment of railway ITS and the monitoring of their impacts. Based on that, a tool for the evaluation of the importance of these indicators is proposed. For that purpose a set of twenty-four indicators was grouped by topics under the economic, social, and environmental dimensions of sustainability. The paper thoroughly describes their development and classification. An evaluation of indicators based on expert opinions via the Group Analytic Hierarchy Process (GAHP) method is presented. Results obtained by the GAHP method illustrate the importance or significance of indicators for railway ITS

DANP-Evaluation of AHP-DSS

The analytic hierarchy process (AHP) and the analytic network process (ANP) are important multi-criteria decision-making (MCDM) methods for solving strategic decision problems. In the field of the research and teaching projects of a university’s Management Science Department, the use of adequate decision support systems (DSS) enables an appropriate application and acceptance of these methods. By reason of the great variety of AHP-DSS, the aim of this paper is the selection of AHP-supporting software. Owing to the interdependencies of the software quality criteria, these influences can be evaluated appropriately by the ANP. As for the various requirements of the different department members, the ANP procedure is linked with the DEMATEL approach. Within such a combined framework (DANP), the alternate software products and their quality selection criteria are transparently analysed and evaluated from a multi-personal point of view. The described procedure is an object of reference to solve such structuring and evaluation problems by support of parallel and/or distributed computing architecture
