Strategic and Operational Management of Supplier Involvement in New Product Development: A Contingency Perspective

This paper examines how firms succeed to leverage supplier involvement in product development. The paper extends earlier work on managing supplier involvement by providing an integrated analysis of results, processes, and conditions at the level of both the individual development projects and the overall firm. Following a multiple-case study approach with theoretical sampling, the study is carried out by examining eight projects in which four manufacturers from different industries involve multiple suppliers. The findings suggest that successful supplier involvement is dependent on the coordinated design, execution, and evaluation of strategic long-term processes and operational short-term management processes and the presence of enabling factors such as a cross-functional oriented organization. The required intensity of these processes and enablers depends on contingencies such as firm size and environmental uncertainty. In contrast with previous research, we find no indications that managing supplier involvement requires a different approach in highly innovative projects compared to less-innovative projects.

某小型无人直升机组合导航设计

在某小型无人直升机的导航设计中,运用了组合导航技术,并将导航数据的获取归结为两个估算任务:姿态信息估算和位置信息估算。在姿态信息估算中,分别从加速度信息和角速率获取了姿态角,然后通过加权和的方式将两者进行融合;在位置信息估算中,用加速度信息进行积分,获得位置和速度,将GPS测量值作为观测量,对估算结果进行修正。实验结果证明,该导航设计能够满足实际需求,且实现简单,对类似工程具有一定的参考价值。     

Implementing computer-aided design: the transition of nonusers

Prior research on the social impacts of computer-aided design (CAD) has treated nonusers, those still using manual methods, as control groups to which users are compared. The assumption is that nonusers' worklives are essentially unchanged by the implementation of CAD. It is argued that nonusers can also be affected by their organization's transition to CAD. It is hypothesized that CAD has primarily job-enhancing effects for the work lives of designers selected to use CAD and primarily negative effects for the work lives of nonusers, who might fear their manual skills would soon be obsolete. Data were collected in two large manufacturing firms through a survey of 74 CAD users and 30 nonusers and through a smaller number of interviews at each site. The results indicate that, compared with CAD users, nonusers were significantly older and spent more time on support and maintenance of old designs and relatively little time on conceptual design work and new design projects     

Electric power generation planning for interrelated projects: a real options approach

The market uncertainties in the generation business in the U.S. electric power industry have increased the significance of two factors in generation planning: financial risks and managerial flexibilities. At the same time,numerous utilities have multiple generation planning projects that are interrelated with respect to their market values. For such utilities, in order to quantitatively address these two factors, in this paper, we develop and analyze a real options model for general n interrelated projects. Specifically, first, we derive a unique lattice process that approximates interrelated continuous processes for the evolution of values of projects and options (e.g., selling a constructed project). The steps of the approximation for n projects are presented progressively starting from two projects. Next, based on the lattice process, we investigate the impact of interrelation on the values of options. Then, we provide a backward dynamic programming model for optimal sequential decision making where the decisions are made over the options. Finally, managerial insights and economic implications are illustrated via numerical examples.     

Global Scope at the National Level: The ITU's Contributions to Telecommunications Development

The International Telecommunication Union's (ITU) work that is oriented towards the needs of developing countries is described. This work is explained as one of two kinds of technical cooperation; the other kind corresponds to the ITU's traditional function as coordinator and standards-maker for international working of telecommunication services. It is shown how these two kinds of technical cooperation both aid each other and compete with each other for funds, top-level organizational attention, and provision of expert manpower. The growth and diversity of cooperative activities for the benefit of developing countries is reviewed in some detail. Numerous examples of handbook-writing and special national or regional projects are given. It is concluded that the ITU exhibits two faces, one directed toward the highly developed country, another toward the developing country in need of help. Maintaining a judicious balance in support of these two personalities represents a challenge to the ITU as a whole, and to its Permanent Organs in particular.     

Practical Profiles for Managing Systems Engineering R&D

A new and practical way of profiling R & D projects is presented. The operational context is the investment of discretionary R & D funds by systems engineering firms. In this work program positioning profile, R & D projects are identified as one of four types: targeting, reinforcing, enabling, or remodeling, according to the relationship between the R &D project and the systems engineering work program. A portfolio map is introduced to provide a visual representation of a set of R & D projects and to show likely transitions between project types over time. The new profile and portfolio map can support management efforts to characterize and assess an R & D portfolio for its contribution to ongoing systems engineering work. In addition to this new project profile, other profiling strategies are discussed in the framework of an R & D balanced scorecard. The multiple profiles are a natural consequence of the inherent performance multidimensionality of the R &D activity in the wide-ranging discipline and practice of systems engineering.

Roles for agent assistants in field science: understanding personal projects and collaboration

A human-centered approach to computer systems design involves reframing analysis in terms of the people interacting with each other. The primary concern is not how people can interact with computers, but how work systems (facilities, tools, roles, and procedures) can be designed to help people pursue their personal projects, as they work independently and collaboratively. Two case studies provide empirical requirements. First, an analysis of astronaut interactions with CapCom on Earth during one traverse of Apollo 17 shows what kind of information was conveyed and what might be automated today. A variety of agent and robotic technologies are proposed that deal with recurrent problems in communication and coordination during the analyzed traverse. Second, an analysis of biologists and a geologist working at Haughton Crater in the High Canadian Arctic reveals how work interactions between people involve independent personal projects, sensitively coordinated for mutual benefit. In both cases, an agent or robotic system's role would be to assist people, rather than collaborating, because today's computer systems lack the identity and purpose that consciousness provides.
