两大传统电信运营商的对比与反思

中国电信与香港的电讯盈科都是传统的固网电信运营商．它们有着许多相似之处：电信市场开放以前唯一的垄断企业；暂时占据着固网运营龙头老大的地位；经历了电信市场改革与重组的阵痛；面临着市场竞争日趋激烈和利润下降的考验：经历着由基础网络运营商向综合信息提供商的战略转型；甚至连电信盈科的企业文化“以客为尊”都与中国电信的“用户至上”如出一辙。     

解读国外固网运营商客户忠诚计划

面对相对饱和的通信市场和移动对固话的替代所带来的越来越激烈的竞争冲击,固网运营商越来越难以通过新增用户来拉动收入增长。面对新增用户越来越少的困境,固网运营商开始将工作重点从获得新用户转向保有老用户。为了有效保有存量老用户,国外固网运营商纷纷推出了各自的客户忠诚计划。

SP的新江湖：运营商重构规则

运营商手中无形的鞭子再次挥出。其政策调整最直接地改变着这个市场的规则。而在3G即将到来的大背景下，运营商对产业链的控制与主导已变得比任何时候都更为迫切和重要。对SP们来说，暴富机会已经逝去，简单生意正变成残酷竞争。市场环境变了，SP的生意理念也要变。突破单一的内容格局和业务格局，摆脱对运营商渠道的过分依赖，SP们需要在不断规范的行业中继续求变。     

3G时代固网运营商客户服务策略分析

新技术的不断引入和“杀手级”应用的缺乏,使耕作于日渐饱和的移动语音市场的电信运营商们不得不正视这样一个现实:3G时代的市场竞争将是,也必然将是客户服务的竞争,即“如何发现并满足客户需求”的竞争。而对于正积极实施“移动化”转型的固网运营商来说,客户服务更是其在获取3G运营牌照后,获取和稳定市场份额、追赶现有移动运营商的唯一契机。固网运营商3G客户服务面临的挑战3G时代的客户服务对固网运营商来说是一个全新的课题。首先,虽然固网运营商通过发展小灵通积累了一些移动市场运营的经验,但在针对个人的客户服务方面与中国移动等…

A Competitive Analysis of Load Balancing Strategies for Parallel Ray Tracing

This paper examines the effectiveness of load balancing strategies for ray tracing on large parallel computer systems and cluster computers. Popular static load balancing strategies are shown to be inadequate for rendering complex images with contemporary ray tracing algorithms, and for rendering NTSC resolution images on 128 or more computers. Strategies based on image tiling are shown to be ineffective except on very small numbers of computers. A dynamic load balancing strategy, based on a diffusion model, is applied to a parallel Monte Carlo rendering system. The diffusive strategy is shown to remedy the defects of the static strategies. A hybrid strategy that combines static and dynamic approaches produces nearly optimal performance on a variety of images and computer systems. The theoretical results should be relevant to other rendering and image processing applications.     

Competitive Pricing Strategies for Software and SaaS Products

We study the pricing strategies for a software firm and an entrant software-as-a-service (SaaS) firm in two customer markets: the market composed of the incumbent’s past customers and the market of new customers. We build a game theoretical model to investigate how user costs and the quality differential between products affect firms’ pricing in different customer markets. Our findings show that it is not always optimal for the software firm to price discriminate between its old users and the new customers. The entrant firm would be better off acquiring only the new customers when the SaaS quality is sufficiently low.

In Search of Concerted Strategies for Competitive and Resilient Regions

The European space-economy represents a complex system with a great internal heterogeneity, intensive socioeconomic interactions and differential growth trajectories among countries and regions. The present study aims to investigate the connectivity between spatial competitiveness and resilience in Europe and seeks to design an operational framework for concerted strategies of competitive and resilient regions. To assess the linkage between resilience and competitiveness, we have developed a new measure, viz. the Resilience and Competitiveness Index (RACI) as a function of two constituent sub-indices: Resilience and Competitiveness. This approach is tested on the basis of detailed data on European regions. The empirical results from 268 EU NUTS2 regions offer a solid anchor point for the proposed operational framework for concerted development strategies of competitive and resilient regions. Our research distinguishes and proposes several systematic types of concerted regional strategies according to the performance of a region measured by Resilience and Competiveness sub-indices. A key result of the study is the design of an operational constellation for strategic regional policy evaluation, with a major added value for policy- and decision-making purposes. The use of official data from Eurostat and of standard indicators in our research assures continuity and consistency with the official Regional Competitiveness Index (RCI) classification and measurement, so that policy makers are able to compare the performance of their regions over time and to develop proper concerted strategies accordingly. The clear evidence of a connectivity between regional competitiveness and resilience may help to develop a governance approach that balances competitiveness (mainly represented by productive assets) with resilience (mainly represented by sustainability and ecological awareness) and thus to deal with the complexity in socioeconomic systems.

Competitive Analysis of Network Load Balancing

This paper presents a theoretical analysis of the Load Balancing Problem (LBP) in a network of processing units. The performance objective is to minimize the makespan, i.e., the time spent to finish all jobs in a network of processing units. Because of the communication delay that results from the network topology, it is impossible to have a strategy which obtains the exact optimum under all load distributions. Instead, we measure the information efficiency of a load balancing policy by the worst case ratio of the solution (for each load distribution) of a load balancing policy to the optimal solution (for the same load distribution) assuming that processors have complete information about the load distribution over the network. This ratio is called the competitive ratio of this strategy [17, 24, 34]. In particular, a policy is calledcompetitiveif this ratio is bounded by a constant. As a first step, we discuss the centralized LBP, where all the processors have complete information of the load distribution over a network. Its solution serves as a benchmark to compare with realistic strategies, both in theoretical analysis, and experimental and simulational studies of distributed algorithms. We show that when jobs have different sizes, even with preemptive scheduling, LBP is NP–complete. When the jobs are of the same size, we give a polynomial algorithm, using network–flow techniques, which extends to approximate solutions for jobs of different sizes. We apply this benchmark solution in order to analyze the competitiveness for three network topologies: completely connected graphs, rings, and hierarchical completek-ary trees. The constant competitive ratio results for complete network and hierarchical completek-ary trees are applied to a study on the issues of network designs suitable for the LBP. We further discuss the problem for general networks with jobs of different sizes for slightly weaker results than those for the constant competitive ratio requirement. Finally, we comment on the related issues of job partitioning over parallel/distributed systems.     

Competitive Analysis of On-Line Disk Scheduling

In this paper we study three popular on-line disk scheduling algorithms, FCFS, SSTF, and LOOK, using competitive analysis. Our results show that, in a competitive sense, the performance of LOOK is better than those of SSTF and FCFS. As a by-product, our analysis also reveals quantitatively the role played by the size of the window, which in our model is a waiting buffer that holds a fixed number of requests waiting to be serviced next. The window, in some sense, offers the lookahead ability which is mentioned in several on-line problems.
