Quality function development (QFD) is a planning tools used to fulfill customer expectation and QFD is a systematic process to translating customer requirement (WHATs) into technical description (HOWs). QFD aims to maximize customer satisfactions related to enterprise satisfaction. The inherent fuzziness of relationships in QFD modeling justifies the use of fuzzy regression for estimating the r...

RÉSUMÉ. Cet article aborde le problème de l’évaluation, par l’agent, de ses actions et interactions. Nous proposons un modèle des satisfactions différenciant actions individuelles et interactions avec les agents voisins. La satisfaction personnelle est calculée incrémentalement dans le temps suivant la perception de la progression de la tâche en cours. La satisfaction interactive est une évalua...

The impact of a major organizational change on general practitioners in the UK was assessed using a postal questionnaire during July-August 1990. The results were compared with those obtained in a previous survey in November 1987. A total of 917 (61 per cent response rate) general practitioners completed the questionnaire measuring aspects of the job causing stress, job satisfaction and mental ...

BACKGROUND Levobupivacaine 0.5% and bupivacaine 0.5% were shown to be equally effective in spinal anaesthesia. In previous studies, low dose bupivacaine with an intrathecal opioid was used successfully in urological surgery. The aim of this study was to evaluate the clinical effectiveness and block quality of low dose levobupivacaine, and compare it with low dose bupivacaine when they are combi...

This paper proposes a new personal tour planning problem with time-dependent satisfactions, traveling and activity duration times for sightseeing. It is difficult to represent the time-dependent model using general static network models, and hence, Time-Expanded Network (TEN) is introduced. The TEN contains a copy to the set of nodes in the underlying static network for each discrete time step,...
