This thesis explores performance criteria adequate to validate simulation models. An overview on the most widely performance criteria used in literature is firstly provided. The thesis proceeds with the proposal of two new criteria that assess the distortion of the warping path obtained after applying the Dynamic Time Warping algorithm: the Warping Path Distortion (WPD) and the Percentage Warpi...

An H2 control performance criterion dependent on a controller parameter vector is analyzed from the point of view of evaluating the domain of attraction of its global minimum when a gradient-based algorithm is used in tuning the parameters. The objective of this analysis is twofold: (i) examine how some design parameters of the criterion can be used to enlarge the domain of attraction; (ii) exa...

Assembly line balancing problem belongs to the most investigated topics in manufacturing systems. Since 1955 a lot of exact and heuristic methods were developed and implemented to real factories. Another problem, which occurs in balance process, is an estimation of quality measures of final results. Even optimal solution because of precedence relations includes idle times. Therefore despite of ...

Data-based control design methods most often consist of iterative adjustment of the controller’s parameters towards the parameter values which minimize an H2 performance criterion. Typically, batches of input–output data collected from the system are used to feed directly a gradient descent optimization — no process model is used. A limiting factor in the application of these methods is the lac...

Performance appraisal is a process that people can comparetheir perceptions of working with major manufacturers’ perceptions.However, when assessment is done from different sources thatare related with self-assessment, called performance appraisal 360 degree.Given the importance of Performance appraisal by 360 degreefeedback in organizations, a model has been provided for 360 degreeperformance ...

This paper presents a scaleable approach to redundancy resolution problems involving multiple criteria. The proposed scheme relies on the disintegration of the inverse kinematics solution from multicriteria decision making. The scheme is composed of systematic generation of a set of inverse kinematics solutions and evaluating these solutions using multiple criteria. The proposed approach is esp...

In previous issues of Endovascular Today, we have described some ongoing initiatives in the Peripheral Vascular Devices Branch intended to optimize our regulation of peripheral vascular devices. Several of these initiatives involve the establishment of standardized objective performance criteria (OPC) and control datasets for various peripheral devices, including iliac stents and endovascular g...

This review paper was presented for the purpose of disseminating among the power electronics community current information on the development of a family of performance criteria and related test protocols at the Power Electronics Application Center (PEAC). The listing of documents in this paper represents a snapshot of the progress at the time (1992). Those documents that were eventually comple...

Performance criteria, such as efficiencies and coefficients of performance, for energy systems, are commonly used but often without sufficient understanding and consistence. The situation becomes particularly incoherent when simultaneous energy interactions of different types, such as work, heating and cooling, take place with a system. Also, the distinction between exergy and Second Law effici...
