With increasing competition, many healthcare organizations have undergone tremendous reform in the last decade aiming to increase efficiency, decrease waste, and reshape the way that care is delivered. This study focuses on the operational efficiency improvement of hospital's registration process. The operational efficiency related factors including the service process, queue strategy, and queue parameters were explored systematically and illustrated with a case study. Guided by the principle of business process reengineering (BPR), a simulation approach was employed for process redesign and performance optimization. As a result, the queue strategy is changed from multiple queues and multiple servers to single queue and multiple servers with a prepare queue. Furthermore, through a series of simulation experiments, the length of the prepare queue and the corresponding registration process efficiency was quantitatively evaluated and optimized.
In the era of Internet+, electric business model has become the key to the success of e-commerce enterprises. B2C model has produced many well-known electrical business empires, such as Yahoo, Ebay, Amazon, and so on. At the same time, because of customers' personalized needs, "consumer-driven" C2B electric business model has become a new growth point by many enterprises. B2C and C2B are the mainstream mode of e-business, and participants are both B -Business and C -the customer. The article will make comparative analysis on background of C2B and B2C, the direction of the supply chain, leader of the value-added process, operational efficiency and utilization of resources, consumer perceived value.
Based on the existing research on multi-project resource allocation, this research presents the triangle relationship diagram about the objective, constraints, and algorithm during project resource allocation; and designs the interactive process for multi-project resource allocation, which combines the project objective, constraint, and algorithm. In addition, a case about fixed period - fixed resources problem is solved to verify the feasibility of the interactive process; the research develops the comprehensive concept for project resource allocation problem.
To improve the accuracy and reliability of operational transfer path analysis (OTPA) in transfer path identification and path contribution evaluation, Landweber-iterative-method-based OTPA is proposed in this paper. Firstly, the vibration data at the reference points and the target points in the operating conditions are obtained. Secondly, the appropriate iteration model and the iterative termination criterion of the Landweber iterative method are designed to improve the fitting degrees of the transmissibility function matrix. Thirdly, the transmissibility function matrix is obtained using the data in experimental operating conditions. Finally, transfer path identification and contribution evaluation are carried out in practical operating conditions, and the major transfer paths are identified. Furthermore, the accuracy, reliability and noise tolerance capability of the proposed method are comparatively studied with truncated singular value decomposition and Tikhonov-regularization-based OTPA, according to typical numerical case studies and experimental case studies on a cylindrical test bed. Generally, the proposed method can obviously improve the accuracy and reliability of transfer path identification and path contribution evaluation, and provide significant evidence for vibration reduction and the control of mechanical systems.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
