The bottleneck (BN) of a production line is a machine that impedes the system’s performance in the strongest manner. It has been shown in the previous work that the so-called downtime bottlenecks (DT-BNs) are of main industrial importance. In this paper, a method for DT-BN identification is developed in the framework of serial production lines with(More)
PURPOSE Improving quality of care is important in health care management. For health care clinics, reducing patient waiting time and improving throughput with efficient utilization of the workforce are important issues to achieve better quality of care. This paper seeks to introduce a simulation study on design and analysis of a health clinic for homeless(More)
In this paper, a system-theoretic approach to bottlenecks in Markovian production lines is introduced and analyzed. The approach is based on the sensitivity of the system production rate to machines’ reliability parameters. Using this approach, definitions of bottlenecks are introduced, methods for their identification are developed, and their implications(More)
Lean buffering is the smallest buffer capacity, which is necessary and sufficient to ensure the desired production rate of a manufacturing system. Literature offers methods for designing lean buffering in production systems with identical machines. The current paper extends these methods to serial production lines with nonidentical machines, assuming that(More)
This paper proposes a model for recognizing motions performed during rehabilitation exercises for frozen shoulder conditions. The model consists of wearable wireless sensor network (WSN) inertial sensor nodes, which were developed for this study, and enables the ubiquitous measurement of bodily motions. The model employs the back propagation neural network(More)
In this study, an autonomous robot is designed to equip an omni-vision camera and an omni-moving platform to meet the requirement of FIRA and RoboCup robot soccer competitions. To make robots obtain its location on the field, we use white-line pattern match localization algorithm to achieve this goal. However, when the white-line information is not complete(More)
