The paper proposes a new integrated approach for supporting firms in their decisions of dimensioning automated production systems. The problem is closely related to the performance evaluation of the system since discriminating indicators are necessary to rank different alternatives. Traditionally analytical methods and simulation have been used to evaluate the production system performance, wit...

Selecting appropriate Open Source Software (OSS) for a given problem or a set of requirements can be very challenging. Some of the difficulties are due to the fact that there is not a generally accepted set of criteria to use in evaluation and that there are usually many OSS projects available to solve a particular problem. In this study, the authors propose a set of criteria and a methodology ...

Performance measurement tools are very important, both for designers and users of database systems, whether they are aimed at On-Line Transaction Processing (OLTP) or OnLine Analysis Processing (OLAP). Performance evaluation is useful to designers to determine elements of architecture, and more generally to validate or refute hypotheses regarding the actual behavior of a system. Thus, performan...

The performance evaluation of sensors is very important in actual application. In this paper, a theory based on multi-variable information fusion is studied to evaluate the health level of multifunctional sensors. A novel conception of health reliability degree (HRD) is defined to indicate a quantitative health level, which is different from traditional so-called qualitative fault diagnosis. To...
