产品生命周期对配送网络设计的影响

为了在当今竞争激烈的市场环境中持续保有较大竞争优势,供应链中企业的配送网络设计必须考虑产品特征与顾客需求的关系.当产品经历整个生命周期不同阶段时,其市场需求的变化往往具有较大不确定性,因此,企业的配送网络必须动态地与产品需求特征进行匹配,才能具有最大的竞争力.本文讨论了配送网络的不同选择以及这些配送网络适合的产品类型,分析了在产品生命周期的不同阶段,如何设计合适的配送网络.最后,以制药业为例来具体分析产品生命周期不同阶段对配送网络设计的影响.     

Local trade networks and spatially persistent unemployment

This paper studies the effects of local trade networks on the spatial distribution of employment in a model that allows for effective demand externalities as well as home bias. It is shown that, if labor can be hired in continuous quantities, then the long run spatial distribution of employment is uniform, and independent of any trade network topology. When labor has binary support, however, local trade networks are found to generate spatial unemployment clusters which can persist indefinitely.

Mitigating shortage and distribution costs in damaged water networks

Recent events have sparked renewed interest in disaster mitigation for public infrastructures. Presidential Decision Directive 63 identifies water distribution as being among the most vital and vulnerable of our large-scale infrastructures. Water distribution networks are vulnerable to threats such as chemical and biological contamination, cyber attacks on computer-based management systems, and physical destruction from acts of nature and intentional attack. This research develops methods for configuring the undamaged portion of the water network to mitigate the consequences of physical destruction. The approach is to find a hydraulically feasible residual network that can be pressurized to meet the demand of a subset of demand sectors. Demand sectors not pressurized then receive water through truck distribution from pressurized sectors. The objective is to minimize weighted water shortage and water truck distribution costs by identifying sectors to pressurize along with an assignment of unpressurized sectors to pressurized sectors for water delivery by truck. The paper develops an optimization model, describes a solution method, and presents computational results for three example networks.

Microscopic spin model for the stock market with attractor bubbling on scale-free networks

A multi-agent spin model for changes of prices in the stock market based on the Ising-like cellular automaton with interactions between traders randomly varying in time is investigated by means of Monte Carlo simulations. The structure of interactions has topology of scale-free networks with degree distributions obeying a power scaling law with various scaling exponents. The scale-free networks are obtained as growing networks where new nodes (agents) are linked to the existing ones according to a preferential attachment rule with an initial attractiveness ascribed to each node. In certain ranges of parameters, depending on the exponent in the degree distribution, the time series of the logarithmic price returns exhibit intermittent bursting typical of volatility clustering, and the tails of the distributions of returns obey a power scaling law with exponents comparable to those obtained from the empirical data. The distributions of returns show also dependence on the number of agents, in particular in the case of networks with the scaling exponents of the degree distributions typical of the social and communications networks.     

‘One Size Does Not Fit All’

Abstract

The article presents a comparative analysis of mandatory networks used as an integrated part of local governance of the primary medical service in Norway, and their management. Both the networks and their management showed considerable variation in their basic characteristics, and three different management roles are described: ‘the diplomat’, ‘the adversary’ and ‘the equal partner’. The article argues that the managerial role of a network is a result of, as well as inflicting on, the distribution of power between the participants in the network.     

Caught in the web: the dual nature of networks and its consequences

Relations between a firm and organizations in its political and economic environment are increasingly seen as crucial for the successful functioning of that firm, both in the narrow economic sense, and at the broader level of reaching sustainability. However, attention seems to be focused on the positive qualities of such networks of organizations. In this paper it is argued that networks of organizations have a dual nature, and do not just provide possibilities for collective learning and problem solving. At the same time, such networks consist of dependency relations that provoke power strategies, which result in outcomes reflecting the distribution of power rather than leading to an optimal result. By means of a case study, this dual nature is explored. It is shown that the actors involved in the process of developing an alternative to the disposable milk carton in the Netherlands are embedded in dependency relations. Several of these actors attempt to create problem solving networks, and succeed. However, the already existing dependency relations between the actors involved influence the direction, outcome, and timing within these networks. Using criteria for network performance, this dual nature of networks is assessed. © 1998 John Wiley & Sons, Ltd and ERP Environment.
