Decision support systems (DSS) typically contain models and data to facilitate decision-making. Users of DSS in response to a decision making situation, often execute a sequence of models, where inputs to a model in the sequence are obtained from outputs of other models upstream in the sequence and from database retrievals. This problem of generating a sequence of models from the set of availab...

Many managerial decisions involve consideration of more than a single criterion. Despite the development of multicriteria decision models (MCI)M), decision support systems (DSS), and group decision support systems (GDSS), there is inadequate success in supporting multicriteria decision making. This study explores the possibility of embedding decision guidance within MCDM GDSS. We outline guidel...

“In this article we propose an approach for a decision support system (DSS) based on Knowledge Discovery from Databases (KDD). In such system, user must be involved throughout the decision-making process. In consequence we propose the integration of a Human–Computer Interaction (HCI) model into the development of DSS process based on KDD. The approach we propose is based on two systems developm...

The Semantic Web shares many goals with Decision Support Systems (DSS), e.g., being able to precisely interpret information, in order to deliver relevant, reliable and accurate information to a user when and where it is needed. DSS have in addition more specific goals, since the information need is targeted towards making a particular decision, e.g., making a plan or reacting to a certain situa...

Objectives: (i) To compare the quality of clinicians’ decisions made with and without computerised triple assessment decision support (TADS) during assessment of women referred to specialist breast cancer units, (ii) To investigate the opinions of clinicians about the decision support software used. Design: Balanced-block crossover experiment with simulated cases; questionnaire study and semi-s...

Past studies suggested that decision support systems (DSS) must be an “enabling” system aiming to enhance users’ capabilities and to leverage their skills and intelligence. This suggests that users be the center of DSS and users’ characteristics be an important factor of explaining their DSS acceptance behavior. Since DSS are aimed to work in semi-structured and unstructured task environment, p...

This dissertation consists of three essays that propose designs and theoretically-based evaluations of two novel decision support systems (DSS): a web-based spatial DSS (SDSS), a dialectic DSS (DDSS), and a comparative analysis of subjective and objective measures of system success in terms of decision process and outcome. In the first essay, a web-based SDSS that utilizes the latest advances i...

Received: 2 April 2009 Revised: 29 September 2009 2nd Revision: 21 September 2010 3rd Revision: 20 January 2011 Accepted: 27 February 2011 Abstract In a number of organisational settings where work is highly skilled but substantially routine, certain entrenched manual systems have resisted digitisation. These systems include card-based systems in emergency despatch, the paper flight progress st...
