An example of analysis of supply chain risk

Postępująca globalizacja w znaczący sposób wpływa na zagrożenia występujące w łańcuchach dostaw. Dotychczas podlegały one kontroli wewnętrznej, obecnie zaś funkcjonują w gospodarce globalnej niosącej za sobą wiele zagrożeń. Wątek zagrożeń w funkcjonowaniu łańcucha dostaw nabiera coraz szerszego znaczenia, tym samym zasługuje na bliższe poznanie i prezentację w niniejszej publikacji. Jednak z racji na rozległość badań w każdym etapie szczegółowo zostanie przedstawiony jeden spośród pięciu obszarów potencjalnych zagrożeń danego łańcucha dostaw. W pracy podjęto temat analizy zagrożeń istniejących w łańcuchu dostaw oraz próbę zracjonalizowania tych niebezpieczeństw na przykładzie praktycznym.Risk assessment is still a problem area within the supply chain. Approaches have been suggested for dealing with the problem, but these for most part have failed to meets the needs of logistics. Part of the problem is that communication, incomplete, and inconsistent. The paper presents an approach of risk assessment in the supply chain. An example case study examining a real supply chain is included to illustrate the analysis of supply chain risk. The authors suggest a method to risk analysis via a multi-criteria approach

Traditional sets versus rest-redistribution: A laboratory-controlled study of a specific cluster set configuration at fast and slow velocities

This study investigated redistributing long inter-set rest intervals into shorter but more frequent intervals at 2 different concentric velocities. Resistance-trained men performed 4 randomised isokinetic unilateral knee extension protocols, 2 at 60°·s−1 and 2 at 360°·s−1. At each speed, subjects performed 40 repetitions with 285 s of rest using traditional sets (TS; 4 sets of 10 with 95 s of inter-set rest) and rest-redistribution (RR; 20 sets of 2 with 15 s inter-set rest). Before and at 2, 5, and 10 min after exercise, tensiomyography (TMG) and oxygenation (near-infrared spectroscopy; NIRS) were measured. NIRS was also measured during exercise, and rating of perceived exertion (RPE) was recorded after every 10 repetitions. At both speeds, RR displayed greater peak torque, total work, and power output during latter repetitions, but there were no differences between TS or RR when averaging all 40 repetitions. The RPE was less during RR at both speeds (p < 0.05). RR increased select muscle oxygen saturation and blood flow at both speeds. There were no effects of protocol on TMG, but effect sizes favoured a quicker recovery after RR. RR was likely beneficial in maintaining performance compared with the latter parts of TS sets and limiting perceived and peripheral fatigue

THE AMERICAN SOCIETY OF MECHANICAL ENGINEERS 501 F Compressor Development Program

ABSTRACT As part of the WESTINGHOUSE-MHI 501F Development Program, a new 16 stage axial flow compressor has been designed. Reported here are elements of the aerodynamic and mechanical design as well as general design features. Overall performance test results are also presented which indicate that the compressor met or exceeded all expectations amenable to measurement during the full load shop test program

Resistance-trained men performed 4 randomised isokinetic unilateral knee extension protocols, 2 at 60°·s−1 and 2 at 360°·s−1. At each speed, subjects performed 40 repetitions with 285 s of rest using traditional sets (TS; 4 sets of 10 with 95 s of inter-set rest) and rest-redistribution (RR; 20 sets of 2 with 15 s inter-set rest).

NIRS was also measured during exercise, and rating of perceived exertion (RPE) was recorded after every 10 repetitions. At both speeds, RR displayed greater peak torque, total work, and power output during latter repetitions, but there were no differences between TS or RR when averaging all 40 repetitions. The RPE was less during RR at both speeds (p < 0.05). RR increased select muscle oxygen saturation and blood flow at both speeds. There were no effects of protocol on TMG, but effect sizes favoured a quicker recovery after RR. RR was likely beneficial in maintaining performance compared with the latter parts of TS sets and limiting perceived and peripheral fatigue. Novelty Although effective at slow velocities, rest-redistribution was likely more effective during high-velocity movements in this study. Rest-redistribution maintained the ability to produce force throughout an entire range of motion. Rest-redistribution reduced RPE during both high-velocity and high-force movements.The accepted manuscript in pdf format is listed with the files at the bottom of this page.
