Using appropriate decision tools is the key factor of making a successful decision. Technologies are changing very fast in today' consumer electronics industry. It is extremely complicated for the buyers to differentiate one product from the other. This paper utilises a decision model, which integrated hierarchical decision-making and utility theories to identify the preferences of IT professionals for computing attributes. The paper then compares the results with those of prior research, which explored student users. The results indicate that the preferences do not change from one group to another. This suggests that the IT organisations may have aligned personal and organisational goals well.","PeriodicalId":170104,"journal":{"name":"International Journal of Decision Sciences, Risk and Management","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127582841","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, until recently, sensitivity analysis has seen only limited application in the area of decision theory and support. This paper investigates the use of sensitivity analysis in the realm of classical Bayesian reasoning, where the probabilities of the states of nature are revised based on additional information. These updated probabilities only become useful, however, if they lead to an optimal decision different from that obtained on the basis of prior probabilities. This paper develops a novel sensitivity analysis procedure for Bayesian decision-making and proposes a set of criteria for the ranges of the model input parameters over which the current solution will remain optimal.","PeriodicalId":170104,"journal":{"name":"International Journal of Decision Sciences, Risk and Management","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130533582","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The modules of the proposed DSS are presented with an emphasis on the model module which implements variations of two well known cutting stock heuristic algorithms that have been modified to support the evaluation of alternative leftover handling policies. Real data obtained by a small Greek company were used for a 'what if' analysis using the proposed DSS. The results obtained, are of particular practical importance since they suggest that the gains achieved by new or improved cutting stock algorithms are in fact lower than the improvements achieved by utilising the leftover pieces.","PeriodicalId":170104,"journal":{"name":"International Journal of Decision Sciences, Risk and Management","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124626909","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a variety of different approaches have been proposed and the construct of EI seems to be at crossroads, a very crucial issue with regard to EI is also the lack of a certain methodology to facilitate the improvement of EI competencies. Research demonstrates that programs which report success in developing EI indicate that mindfully identifying behaviours to be changed in combination with opportunities to exercise new skills result in producing more lasting behavioural changes. The primary goals of this literature review based paper are to display the importance of self-directed learning in EI change process, to demonstrate that a methodology based on the incorporation of imagined interactions (IIs) assist EI competencies to be developed. Both of the above assist training on EI to be more efficacious. In this paper it is demonstrated that IIs relate directly to self-directed learning assisting EI change.","PeriodicalId":170104,"journal":{"name":"International Journal of Decision Sciences, Risk and Management","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128751833","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Given the nonlinear and time-varying characteristics of international crude oil prices, this study employs the recently proposed delay vector variance (DVV) method that examines local predictability of a signal in the phase space to detect the determinism and nonlinearity in a time series. In addition, wavelet transforms, which have recently emerged as a mathematical tool for multi-resolution decomposition of signals, is utilised. In particular, among the wavelet methodologies considered, the complex Morlet wavelet is useful and best at detecting the various phases of oil prices through the trajectory of market developments. The findings of this paper highlight the significant phases of the series and its relation to real-world phenomena with an indication of early warning signals of future significant events, thereby providing a guide for proper decision making and risk management practices of market participants.","PeriodicalId":170104,"journal":{"name":"International Journal of Decision Sciences, Risk and Management","volume":"232 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114424055","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Operations on seaport terminals can be further enhanced by optimising processes and technical upgrades. The role of the general environment, however, often remains neglected. This paper aims to reintroduce exogenous factors to the contemporary land productivity analysis. We develop a conceptual framework for the identification of relevant exogenous factors and the potential impacts these factors have on the possibilities for the terminal operator to achieve a high land productivity. The framework to address exogenous drivers serves as the basis for a guided survey. Terminal operation experts were asked to assess exogenous factors in relation to land productivity. The results indicate that exogenous factors are considered a valuable contribution.","PeriodicalId":170104,"journal":{"name":"International Journal of Decision Sciences, Risk and Management","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122065738","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
