Over the past decades the complexity of financial decisions has increased rapidly, thus highlighting the importance of developing and implementing sophisticated and efficient quantitative analysis techniques for supporting and aiding financial decision making. Multicriteria decision aid (MCDA), an advanced branch of operations research, provides financial decision makers and analysts with a wid...

Most companies register a large quantity of information in their maintenance data bases, but this is often poorly exploited. An efficient valorization of a maintenance history can improve future maintenance strategies. In maintenance optimisation, four general types of maintenance strategies are taken into account such as: a) corrective, b) preventive, c) predictive, and d) reliability centered...

The Modular Ocean Data Assimilation System (MODAS) produces oceanographic nowcasts based on a) climatology, b) remotely-sensed sea surface temperature and height, and c) in-situ measurements. Recent analyses have shown that the locations of in-situ measurements can have a profound influence on the accuracy of the MODAS synthetic profiles. Small-scale variability combined with sparse sampling an...

BACKGROUND Acute trauma of the wrist is one of the most frequent reasons for visiting the Emergency Department. These patients are routinely referred for radiological examination. Most X-rays however, do not reveal any fractures. A clinical decision rule determining the need for X-rays in patients with acute wrist trauma may help to percolate and select patients with fractures. METHODS/DESIGN...

The ®nancial decisions of an organization are usually included in the context of optimization. Concerning a longterm period, there are decisions related to the optimal allocation of funds, and decisions related to the optimal ®nancial structure. In the short-term case, the decisions are related to the optimization of stocks, cash, accounts receivable, current liabilities, etc. The ®nancial theo...

This study investigates the roles trust and bias may play in nursing information technology acceptance via a two-phase study. In phase one, the impact of user experience on levels of trust in and bias towards automated decision aids (ADAs) is assessed. In phase two, the impact of trust and bias on ADA adoption is explored using actual usage data. The results indicate that experienced nurses hav...

Recommender systems provide decision aid and information filtering functions that have a great potential application in the mobile context. An aspect which has not been extensively exploited, in current recommender systems, are ways to better explain the recommendations, for instance, exploiting the opinion of users about the recommended products. In this paper we shall describe the foundations...

Maintenance and inspection errors have been the primary cause of six percent of aircraft accidents and have contributed to an additional nine percent of the accidents from 1982 through 1993. What can maintenance organizations do to reduce these types of errors? This paper discusses the development and evaluation of a maintenance error investigation process--the Maintenance Brror Decision Aid (M...

This paper presents an improved version of an application whose goal is to provide a simple and intuitive way to use multicriteria decision methods in day-to-day decision problems. The application allows comparisons between several alternatives with several criteria, always keeping a permanent backup of both model and results, and provides a framework to incorporate new methods in the future. D...

Traditionally, at least until recently, OR has mainly been based on models which postulate the existence of a unique objective (single-criterion) function. It was thus assumed implicitly that in order to help organizations improve their decision-making, there was a general rule, or objective function, which stood out in everybody’s eyes to indicate the proper direction in which a given system h...
