유연흐름라인에서의 동태적 작업흐름 통제

文碩煥 경북대학교 경제경영연구소 1990 經商論集 Vol.18 No.4

This research involves the development and evaluation of a work flow control scheme for a type of flexible flow line(FFL) with limited buffer space. Work flow contorl scheme for the FFL includes two major functions: releasing and dispatching. A simple releasing scheme called Workload Balancing(WLB) rule was developed. WLB rule attempts to minimize the deviation of the system workload from the ideal state in which the current system workload is proportional to the workload in the remaining job pool for each machine center. Dispatching decision was made using either SOT(Shortest Operation Time) rule or LOT(Longest Operation Time) rule depending on the workload level at the current machine center; where the decision is require, and the subsequent machine center. The performance of the control scheme was compared via computer simulation to that of Minimal Part Set(MPS) heuristic which is another simple control scheme reported in the literature. The simulation results indicate that the performance of the WLB rule is superior to the MPS heuristic.

김의환,조동희,권문석 한국운동역학회 2002 한국운동역학회지 Vol.12 No.1

The purpose of this study was to analyze the kinematic variables of Uchi-mata(inner thigh reaping throw) by Kumi-kata(engagement position, basic hold) types A, B in Judo with three dimensional analysis technique and show the kinematic characteristics of it. The subjects of the experiment were judokas who have been attending in Yong-in University(YIU), and Uchi-mata is their tokui-nage(favorite technique), the throwing form was filmed on 16mm video camera( 30frame/sec.) Kinematic variables were temporal, posture, and COG(Center of Gravity). The mean values and the standard deviation for each varibles were obtained and used as basic factors for examining characteristics of Uchi-mata by Kumi-kata types. The results of this analysis were as follows 1) Temporal variables The total time elapsed(TE) of Uchi-mata of types A, B were 1.45, 1.56 sec. respectively. Types A and B were not quite different on every phase. 2) Posture variables In performing of Uchi-mata, the range of flexion in type A, left elbow was 45?and B was 8 9?from Event 2(E2) to Event 6(E6). Type A and B were quite different in right elbow angle in Eventl(E1). Left shoulder angle of type A was extended and type B was flexed in E4. Both types right shoulder angles were showed similar pattern. Also both hip angles(right/left) were showed similar pattern. When type A performed Uchi-mata the knee-angle of supporting foot showed 142?in the 1st stage of kake phase[KP], and extended to 14T in the 2nd stage of KP. And the foot-ankle angle of supporting foot showed 83?in the 1st stage of KP, and extended to 86?in the 2nd stage of KP. moreover, The knee angle of attacking foot showed 12W in the 1st stage of KP, and extended to 132?in the 2nd stage of KP, and the foot-ankle angle of attacking foot showed 10 6?in the 1st stage of KP, and extended to 121?in the 2nd stage of KP. When type B performed Uchi-mata the knee-angle of supporting foot showed 144?in the 1st stage of KP, and extended to 154?in the 2nd stage of KP. And the foot-ankle angle of supporting foot showed 83?in the 1st stage of KP, and extended to 92?in the 2nd stage of KP. moreover, The knee angle of attacking foot showed 132?in the 1st stage of KP, and extended to 140?in the 2nd stage of KP, and the foot-ankle angle of attacking foot showed 103?in the 1st stage of KP, and extended to 115?in the 2nd stage of KP. So, in performing of types A, B, it showed that the type B extended more than type A, but the ankle angle of attacking foot showed dorsiflexion. 3) C. O. G. variables When the subjects performed Uchi-mata, COG of type A, B up and down in vertical aspect was 71cm, 73.8cm in height from the foot in the 2nd stage of KP. The COG of right and left in frontal aspect showed the large move from the left to the right on both types

권문석,김의환,조동희 한국운동역학회 2002 한국운동역학회지 Vol.12 No.2

본 연구는 6년 이상의 유도경력 소유자인 Y.대학교 유도전공자를 대상으로 맞잡기 타입과 받기신장에 따른 허벅다리걸기 동작시 3차원 영상분석법을 이용하여 운동학적 변인의 특성을 분석하는데 그 목적이 있다. 유도 맞잡기 타입과 받기신장에 따른 허벅다리걸기 동작은 비디오카메라 2대를 사용하여 촬영(30frame/sec.)하였으며, 분석을 위한 운동학적 변인들은 시간, 자세, 중심변인이며, 실험 결과에 대한 분석과 논의를 통하여 다음과 같은 결론 및 제언을 얻을 수 있었다. 허벅다리걸기 동작의 맞잡기 타입에 따른 유의한 차이는 3국면 소요시간, 걸기1단계 공격둔부각, 걸기1단계 공격무릎각, 걸기2단계 공격무릎각, 걸기2단계 지지무릎각, 걸기1단계 공격발목각, 걸기2단계 지지발목각에서 유의한 차이(p<.05)를 보였다. 종합해보면, 허벅다리걸기를 수행할 때 맞잡기와 상대신장이 허벅다리걸기 기술에 영향을 미친다는 것을 알 수 있었으며, 상대의 신장이 작을 경우 목 뒤를 잡는 타입 A가 시간이 단축(<.05)되었다. 따라서 경기 중 상대의 신장이 작다면 목 뒤를 잡는 것이 유리하다.이러한 사실들을 종합해 볼 때, 유도 경기 중 허벅다리걸기를 수행할 대 맞잡기가 많은 영향을 주었다. 또한 기술의 핵심단계인 3(걸기)국면에서도 받기신장에 의한 차가 더 크게 나타나 받기신장 역시 많은 영향을 주었다. 단계별 변인들의 변화량에 있어서는 전체적으로 모든 변인들이 변화량에서 큰 차이를 나타내지는 않았다고 할 수 있다. 따라서 맞잡기와 받기신장은 상당한 관계가 있음을 알 수 있었으며 유도 경기 중 상대에 따른 다양한 잡기와 신장을 고려한 기술이 요구된다. This study was to analyze the kinematic variables when the subjects performing Uchi-mata(inner thigh reaping throw) by Kumi-kata types((How to grasp A or B?) and two different opponent's height in Judo. Kinematic variables were temporal, posture. Data analysis was collective comparison of two-way ANOVA, t-test by type A&B and two different opponent's height. There were significant difference of Kumi-kata types(p<.05) in the time elapsed on Kake phase(KP : throwing phase) and hip, knee, ankle-angle of the attacking foot in the 1st stage of KP and knee, ankle-angle of the attacking foot and hip, knee ankle-angle of the supporting foot in the 2nd stage of KP. There were significant difference of two opponent's(p<.05) in the time elapsed on KP and hip-angle of the supporting foot in 1st stage of KP. Therefore, the interaction effect(p<.05) were in the time elapsed on KP and hip-angle of the supporting foot in the 2nd stage of KP. So, It could be suggested that Judoka hold on the part-behind neck lapel(type A) at the sleeve with the other of Judogi jacked when opponent's height was short. Because the time elapsed on KP of type B was not so fast as type A(p<.05) during performed Uchi-mata, and also the bigger hip-angle of the supporting foot in the 2nd stage of KP grew, the faster the time elapsed on KP became.
