Purpose – This paper aims to explore if actions used at a hospital to manage a variable acute patient flow can be categorised using the concepts of lean, agile and leagile. Design/methodology/approach – Empirical evidence from a university hospital was gathered by interviews, internal documents, shadowing and participation in meetings. Identified actions used at both hospital level and departmental level are categorised as lean or agile, while combinations of actions are compared with different leagile approaches. Findings – Actions from every lean and agile category derived from literature are used at the hospital, however in varying extent. Many agile actions are reactive, indicating a lack of proactive measures. Actions that directly manage external variation are also few in numbers. Leagile approaches of all three combinations derived from literature are also used at the hospital. Research limitations/implications – As a single-case study is used, empirical generalisation to other hospitals cannot be deduced. Future research assessing the appropriateness of different actions for managing a variable acute patient flow is encouraged. Practical implications – The use of actions within both lean and agile categories indicate the possibility of combining these process strategies in hospitals, and not only focusing on implementing lean. By cleverly combining lean and agile actions, leagile approaches can be formed. Originality/value – The use of lean in health care has been a topic of research, while the use of agile has been sparsely researched, as well as the combination of the two.

Abstract The safety and risk of the long term serviced pressure vessels, especially which serviced more than 20 years, has become one of the most concerned issues in refining and chemical industry and government safety supervision in China. According to the Chinese pressure vessel safety specification TSG 21-2016 “Supervision Regulation on Safety Technology for Stationary Pressure Vessel”, if necessary, safety assessment should be performed for the pressure vessel which reaches the design service life or exceeds 20 years without a definite design life. However, the safety and risk conditions of most pressure vessels have little changes after long term serviced because their failure modes are time-independent. Thus the key problem is to identify the devices with the time-dependent failure modes and assess them based on the failure modes. This study provided a case study on 16 typical refining and chemical plants including 1870 pressure vessels serviced more than 20 years. The quantitative risk and damage mechanisms were calculated based on API 581, the time-dependent and time-independent failure modes were identified, and the typical pressure vessels were assessed based on API 579. Taking the high pressure hydrogenation plant as an example, this study gave the detailed assessment results and conclusions. The results and suggestions in this study are essential for the safety supervision and extending life of long term serviced pressure vessels in China.

On The Road

<p><span>The modeling of a car is essentially done by taking into consideration the driving terrain, traffic conditions, driver’s behavior and various other factors which may directly or indirectly affect the vehicle’s performance. A vehicle is modeled for given specifications and constraints like maximum speed, maximum acceleration, and braking time, appropriate suspension for the gradient of the road and fuel consumption. Henceforth, a profound study and analysis of different drive cycles are essential. A time dependent drive cycle is a condensed form of data that helps us to determine the time taken to conduct the driving test on the road. This article highlights the development of a real driving cycle in the area of Tamilnadu, India. On-road vehicle’s speeds versus time data were obtained along the selected route. The data obtained were analyzed first and then a new driving cycle was developed.</span></p>

Air wake distribution around the superstructure of a mega-yacht is a key concern for the designer because of various reasons such as comfort expectations in recreational deck areas, self-noise generation, air pollution and temperature gradients due to exhaust interactions, and safety of helicopter operations such as landing/take off and hovering. The Reynolds-averaged Navier-Stokes (RANS) technique in computational fluid dynamics (CFD) is frequently used in studies on mega-yacht hydrodynamics and aerodynamics with satisfactory results. In this article, a case study is presented for the utilization of CFD in a mega-yacht's superstructure design. The flow field in recreational open areas has been analyzed for the increase in velocity due to the existence of the superstructure. A reduction in self-noise of the mast structure has been aimed by reducing flow separation and vorticity. Time-dependent velocity data obtained with scale-resolving simulations are presented for the evaluation of helicopter landings. The capabilities and limitations of the RANS technique are discussed along with recent developments in modeling approaches.
