发电企业如何部署统一通信平台

回顾我国发电企业信息化之路,已经走过近半个世纪的沧桑历程,发电企业独特的生产与经营方式决定了其信息化发展的模式,由于历史原因和发展的不均衡性,目前依然存在大大小小的"孤岛"。近两年,统一通信的呼声一浪高过一浪,已经成为IT界的热门话题,被权威专家称之为IT整合的最佳平台。统一通信理念的提出,为解决发电企业"信息孤岛"提供了契机。本文通过回顾发电企业信息化发展历程,分析存在的问题,提出了发电企业统一通信建设的原则和实施建议。     

井下无线传感器网络部署算法

为了更为有效地进行矿井数据监测和采集,保证安全生产,本文提出了一种基于最大通信距离的矿井无线传感器网络部署算法。进一步地,本文给出了一种通过部署备用节点优化无线传感器网络性能的策略,以克服原部署算法导致地网络健壮性不强、覆盖率偏低等缺点。实验仿真结果表明,优化后的无线传感器网络的健壮性和覆盖率都有了较大的提高。

Role of policy in the development of business models for battery storage deployment: The California case study

California has been one of the early adopters of battery storage technologies within the United States. The state has used multiple policy initiatives such as deployment targets, financial incentives, and market mechanisms to facilitate such a market development. This motivates us to try to understand the various business models in the state and the minimum set of barriers that must be overcome for its successful deployment (and thereby the development of the market). In our study, the former is achieved by assessing the various projects in the state, and the latter by creating a barrier-solution framework and verifying it by identifying the role of various policies/drivers in supporting various business models within California. We find that there are predominantly three business models in California: Front-of-the-meter, Behind-the-meter, and Aggregated Behind-the-meter business models. We also find that at least one barrier from barrier categories associated with market demand and project economics along with all the barriers related to interconnection and market participation must be addressed for successful deployment of battery storage. Additionally, we recommend policymakers seeking to develop a battery storage market to start with developing Behind-the-meter market as it requires the least amount of intervention and then move to develop Front-of-the-meter market, and finally to the aggregated Behind-the-meter market.

基于ERP的质量驱动产品设计研究

ERP中的企业资源计划信息不仅能用于企业资源优化配置,还能为产品设计决策提供非常有用的信息。目前产品设计阶段一般没有充分利用ERP中的信息,针对这种情况,在分析质量驱动产品设计内涵的基础上,提出了基于ERP的质量驱动产品开发的概念,建立了以质量功能展开（QFD）和故障模式效应分析（FMEA）为核心的基于ERP的质量驱动产品开发系统模型,最后给出了系统的信息交换机制与方法。

Scaling up biomass gasifier use: an application-specific approach

Biomass energy accounts for about 11% of the global primary energy supply, and it is estimated that about 2 billion people worldwide depend on biomass for their energy needs. Yet, most of the use of biomass is in a primitive and inefficient manner, primarily in developing countries, leading to a host of adverse implications on human health, environment, workplace conditions, and social well being. Therefore, the utilization of biomass in a clean and efficient manner to deliver modern energy services to the world's poor remains an imperative for the development community. One possible approach to do this is through the use of biomass gasifiers. Although significant efforts have been directed towards developing and deploying biomass gasifiers in many countries, scaling up their dissemination remains an elusive goal. Based on an examination of biomass gasifier development, demonstration, and deployment efforts in India—a country with more than two decades of experiences in biomass gasifier development and dissemination, this article identifies a number of barriers that have hindered widespread deployment of biomass gasifier-based energy systems. It also suggests a possible approach for moving forward, which involves a focus on specific application areas that satisfy a set of criteria that are critical to deployment of biomass gasifiers, and then tailoring the scaling up strategy to the characteristics of the user groups for that application. Our technical, financial, economic and institutional analysis suggests an initial focus on four categories of applications—small and medium enterprises, the informal sector, biomass-processing industries, and some rural areas—may be particularly feasible and fruitful.
