재구성 생산시스템에서 생산용량 결정을 위한 알고리즘 개발
정택섭(Taek-Seop Jeong),이규봉(Gyu-Bong Lee) (사)한국CDE학회 2011 한국 CAD/CAM 학회 학술발표회 논문집 Vol.2011 No.1
Reconfigurable manufacturing system (RMS) was introduced promptly to meet the problem that output of parts to be manufactured should be suddenly changed by a demand of market. In this paper, determination of optimal production capacity in RMS is surveyed with two viewpoints. One viewpoint is to increase or decrease number of tools or machines according to the output of parts and the other is to reconfigure an existing system or add new system with variation of the number. A linear programming algorithm is supposed to solve the optimal problem with model of performance evaluation of RMS.

We have developed a Ultra Sound Pulsed Doppler System with two-dimensional M-mode image and Spectrum analyzer. The image of the M-mode is composed of time depth axes. The Spectrum analyzer shows the spectrum of Doppler signal which represents the velocity component of time dependent blood-flow behavior. The spectrogram using Spectrum analyzer is composed of frequency and amplitude axes. The outputs of the system are audio signals, velocity curves, velocity profiles, M-mode images and spectrogram.
