Integrating commercial and residential pickup and delivery networks: A case study

This paper presents a strategic analysis of the network design problem faced by pickup and delivery companies operating in metropolitan areas and serving two or more classes of customers. The focus is on a division that treats commercial and residential customers separately, a situation motivated by their respective geographic densities and the size and frequency of their demand. In constructing driver work areas, it is necessary to take into account expected demand, vehicle capacity, time on the road, and the aspect ratio of the individual territories. This leads to a capacitated clustering problem with side constraints that has been the subject of intense research over the last decade.     

Product universality and design for supply chain management

We describe our experience of developing models in which the principles of design for supply chain management (DFCM) have been implemented for new product development at Hewlett-Packard Company (HP). This experience arises from the development of a new product that is scheduled to be released in 1995. A key design decision faced by the product development team was whether to use a universal module or regionally dedicated modules to satisfy global market requirements. We describe a wide range of factors—including manufacturing and logistics costs—that could be used to support the design decision; these factors associated with product and process design contribute to tolal supply chain costs. We review the analytical model used to evaluate the cost and service implications of the two design alternatives. Finally, we discuss qualitative considerations that might influence the eventual decisions as well as the lessons learned from this real world experience.     

Situational production management: a practical theory for the development and application of production management

Discussions in journals and at conferences often nurture the dream of the ultimate method which may be applied successfully to all situations. Yet everybody knows that ‘it all depends’ and that situational factors determine which methods and systems are appropriate. This paper sets forth to outline a practical theory of a situational approach to production management. Any improvement of production management is seen as a dialogue between identification of the production management task, on the one hand, and specifying a solution system, on the other. A few concepts are introduced to provide practical methods for carrying out an improvement process; in particular, the nature of the production management task is addressed. The implications of the situational theory to be presented are discussed for three levels of application, respectively, the general level, the industry level, and the level of an individual industrial enterprise. It is further argued that the three levels are interdependent and that their joint application may stimulate both the theoretical and practical development of production management.     

The perceptions of human resource development professionals in Taiwan regarding their working relationships with subject matter experts (SMEs) during the training design process

While the literature supports the importance of establishing a relationship between designers and subject matter experts (SMEs) in the training design process, this approach is not followed in all global practices. The purpose of this study was to identify the perceptions of human resource development professionals in Taiwan regarding their working relationships with SMEs. The respondents of the study were HRD professionals who worked in high-tech companies located in a science park in Taiwan. The study found that a significant relationship exists between the ability to work with SMEs and current ability in the training design process among HRD professionals who had worked with SMEs. This study provides implications for the professional development of HRD practitioners and HRD practice in Taiwan companies. Cross-cultural issues are discussed to explain inconsistencies between the results and US-based perspectives on the training design process.     

Effective design of a global leadership programme

The purpose of this paper is to report level 3 evaluation findings from a leadership development programme. This paper comprises a case study, quantitative data analysis, and results from critical incident semi-structured interviews. A unique research model was developed from a literature review. There are many problems associated with the design and delivery of leadership development programmes. Senior executive-taught workshops, 360° feedback, and action learning were deliberately employed to increase the adoption and application of specific behaviours after the programme. The results substantiate previous findings on the impact of these elements by demonstrating concrete behavioural changes rather than perceived enhancement in leadership capabilities as often cited in other studies. The model should be further tested, applied and refined as necessary.

Organizations wishing to develop leaders could be guided by the model and findings of this research. A novel and innovative design model was developed from a literature review, tested against a leadership programme in a large well-known multi-national organization, and later refined based on the empirical results. It will be of value to HRD managers and researchers.     

Action e-learning: An exploratory case study of action learning applied online

Abstract

Web-based instruction, also called e-learning, is currently one of the most talked-about education and training media. To prepare courses for online delivery and to maintain their effectiveness, the designer must have an understanding of e-learning instructional design principles. Action learning is a proven, effective management development process that has not been implemented to date as an e-learning instructional methodology. The purpose of this exploratory case study was to examine the impact of the action learning process on the effectiveness of management level web-based instruction (WBI). A leader-led, management-level course using face-to-face delivery was converted to web-based instruction where action learning was the delivery methodology. Kirkpatrick's Four Levels of Evaluation served as the evaluation tool to determine effectiveness of the intervention. It was found that, though challenging to facilitate, the action learning online method is effective and yields changes in participants' knowledge. However, contrary to expectations, online learning communities did not form.     

中国设计产业与工业的互动关系研究——基于独立设计机构专利数据的相关前沿理论验证

以中国独立设计机构的授权专利为研究对象,通过中国专利数据检索,对中国设计机构专利授权数量时间序列进行统计和预测,结合工业增加值数据,运用相关分析、协整检验和格兰杰因果检验等计量方法,初步验证Porter钻石模型的服务需求理论和Grossman的设计驱动的内生增长理论在中国的适用性.研究结果表明,1985年至2009年中国独立设计机构专利迅速增长,Porter钻石模型的服务需求理论在中国得到部分支持,但Grossman的设计驱动的内生增长理论在中国没有得到证实,设计产业还不是驱动工业增长的力量.     

A Taguchi-based Kansei engineering study of mobile phones at product design stage

This article is aimed at applying Taguchi method in Kansei engineering and explores a way to integrate it into an industrial product design stage. Emotional customer needs are derived using Kansei image word pairs. The Taguchi-based approach is validated by a case study with mobile phones. Experimental work in implementing the proposed approach was able to suggest design attributes of a mobile phone that are essential to be considered at the product design stage to satisfy the customers’ expectations and hence to increase the company's sales.     

A pragmatic adaptive enrichment design for selecting the right target population for cancer immunotherapies

One of the challenges in the design of confirmatory trials is to deal with uncertainties regarding the optimal target population for a novel drug. Adaptive enrichment designs (AED) which allow for a data-driven selection of one or more prespecified biomarker subpopulations at an interim analysis have been proposed in this setting but practical case studies of AEDs are still relatively rare. We present the design of an AED with a binary endpoint in the highly dynamic setting of cancer immunotherapy. The trial was initiated as a conventional trial in early triple-negative breast cancer but amended to an AED based on emerging data external to the trial suggesting that PD-L1 status could be a predictive biomarker. Operating characteristics are discussed including the concept of a minimal detectable difference, that is, the smallest observed treatment effect that would lead to a statistically significant result in at least one of the target populations at the interim or the final analysis, respectively, in the setting of AED.
