Concurrent engineering has been widely accepted as a viable strategy for companies to reduce time to market and achieve overall cost savings. This article analyzes various risks and challenges in product development under the concurrent engineering environment. A three‐dimensional early warning approach for product development risk management is proposed by integrating graphical evaluation and review technique (GERT) and failure modes and effects analysis (FMEA). Simulation models are created to solve our proposed concurrent engineering product development risk management model. Solutions lead to identification of key risk controlling points. This article demonstrates the value of our approach to risk analysis as a means to monitor various risks typical in the manufacturing sector. This article has three main contributions. First, we establish a conceptual framework to classify various risks in concurrent engineering (CE) product development (PD). Second, we propose use of existing quantitative approaches for PD risk analysis purposes: GERT, FMEA, and product database management (PDM). Based on quantitative tools, we create our approach for risk management of CE PD and discuss solutions of the models. Third, we demonstrate the value of applying our approach using data from a typical Chinese motor company.  相似文献

We link patronymics (first and last names presented together) to success in the job market by investigating the influence of name attractiveness on employability. Using data from a recruitment agency, we tested (binomial regression) for effects associated with age, gender, and name attractiveness on job interview outcomes. We found that candidates with more attractive patronymics were more likely to be retained by employers.  相似文献

A frustration often expressed by researchers and policy-makers in public health is an apparent mismatch between respective priorities and expectations for research. Academics bemoan an oversimplification of their work, a reticence for independent critique and the constant pressure to pursue evaluation funding. Meanwhile, policy-makers look for research reports written in plain language with clear application, which are attuned to current policy settings and produced quickly. In a context where there are calls in western nations for evidence based policy with stronger links to academic research, such a mismatch can present significant challenges to policy program evaluation. The purpose of this paper is to present one attempt to overcome these challenges. Specifically, the paper describes the development of a conceptual framework for a large-scale, multifaceted evaluation of an Australian Government health initiative to expand Nurse Practitioner models of practice in aged care service delivery. In doing so, the paper provides a brief review of key points for the facilitation of a strong research-policy nexus in public health evaluations, as well as describes how this particular evaluation embodies these key points. As such, the paper presents an evaluation approach which may be adopted and adapted by others undertaking public health policy program evaluations.  相似文献

In performance evaluations, data without explicit inputs (such as index data, pure output data) are widely used. To directly use such data, this paper presents a study on building DEA models without explicit inputs, so-called DEA-WEI models, which are applicable to the evaluation applications where inputs are not directly considered. We provide an axiom foundation of these kinds of models, and further discuss how to incorporate value judgments of decision makers into these DEA-WEI models. Several such models are derived. Finally, applications of the DEA-WEI models are presented.  相似文献

In community-based health enhancing physical activity (CBHEPA) programmes, group-based principles for action such as active participation, enjoyment, and fostering group processes are widely advocated. However, not much is known about participants’ perceptions of these principles as there are no assessment tools available. Therefore, this article describes the development of the APEF (Active Participation, Enjoyment, and Fostering group processes) tool and reports on its implementation in a Dutch CBHEPA programme. Indicators for the principles have been identified from literature research, interviews with professionals, and secondary analysis of three group interviews with 11 practitioners. To address the identified indicators, the APEF tool was developed, pretested, and used in 10 focus groups with 76 participants.The APEF tool consists of eight statements about group-based principles for action, on which CBHEPA participants vote, followed by in-depth discussion. The voting procedure engages participants. Spider diagrams visualise participants’ perceptions of group-based principles.The APEF tool addresses the challenge of relating group level outcomes to individual outcomes such as physical activity behaviour. The tool facilitates as well as evaluates group-based principles for action, it stimulates dialogue and is culturally sensitive, but it needs strong facilitating skills to manage group dynamics.  相似文献

关于当前我国领导干部公选制问题的探讨   总被引:2,自引:0,他引:2  
领导干部选拔任用工作是我国政治体制改革与政府管理中最为关键与重要的问题。本文对于当前我国领导干部公开选拔任用制度的概念形成、制度化基础、发展过程及其实践形式进行了初步探讨。对于考任制、选任制、竞任制与票决制等不同形式进行了独立的解释。对于当前领导干部的公选制,从学科理论上进行了基础分析,从实践过程层面进行了问题分析。就公选制如何改进竞聘者理论上的广泛性与实际中的有限性、评价主体的多元性与价值观的不一致性、标准的科学性与可操作性等六大问题提出了相关的对策与建议。  相似文献

Abstract

One or two session psychotherapy has a long history, and well-known practitioners have made use of it. Favorable results have been reasonably well documented. Often it has been done out of necessity, less frequently because all were satisfied that it sufficed. Problems that lend themselves to one or two sessions are: psychological work which has already been done but for which affirmation is sought, requests for diagnostic evaluation, and less often but more challenging, intrapsychic conflict requiring uncovering work. Patient characteristics and therapist attitudes are discussed. For one or two sessions of treatment to occur the therapist must be alert to the possibility, must assess quickly when a case is in hand, set the process in motion, and determine a satisfactory stopping point. It is suggested that the college population lends itself especially well to one or two sessions of psychotherapy, not only from the standpoint of the limited resources of many student health services but also for the ego strengthening potential it provides.  相似文献
