An application of the AHP in vendor selection of a telecommunications system

Abstract: Vendor selection of a telecommunications system is an important problem to a telecommunications company as the telecommunications system is a long-term investment for the company and the success of telecommunications services is directly aected by the vendor selection decision. Furthermore, the vendor selection of a telecommunications system is a complex multi-person, multi-criteria decision problem. The group decision-making process can be improved by a systematic and logical approach to assess priorities based on the inputs of several people from dierent functional areas within the company. The analytic hierarchy process (AHP) can be very useful in involving several decision-makers with dierent conicting objectives to arrive at a consensus decision. In this paper, an AHP-based model is formulated and applied to a real case study to examine its feasibility in selecting a vendor for a telecommunications system. The use of the proposed model indicates that it can be applied to improve the group decision making in selecting a vendor that satises customer specications. Also, it is found that the decision process is systematic and that using the proposed AHP model can reduce the time taken to select a vendor. ? 2001 Elsevier Science Ltd. All rights reserved.

Traffic modeling for telecommunications networks

Abstract: As new communications services evolve, professionals must create better models to predict system performance. The article provides an overview of computer simulation modelling for communication networks, as well as some important related modelling issues. It gives an overview of discrete event simulation and singles out two important modelling issues that are germane to extant and emerging networks: traffic modelling and rare event simulation. Monte Carlo computer simulation is used as a performance prediction tool and Markov models are considered. >

Telecommunication user account management system and method

Abstract: The present invention is an integrated computerized system and method of telecommunication user account management. The invention creates, maintains, processes and analyzes data regarding individual users for telecommunication services. Billing for individual users is generated. The user data is analyzed and reports for all or part of the user data are prepared and generated. Ancillary functions are enabled, including word processing, editing, e-mail, and other functions. The invention is applicable to subscriber telecommunication services, and pay-for-use services, and the user may be a subscriber or a non-subscriber. The invention is applicable to multi-channel telecommunication services, or single channel multi-service telecommunications, or single channel single service telecommunications. Such telecommunication services may include cable television, telephone, video, audio, on-line databases, television, radio, music video, video juke box, pay-for-view, video-on-demand, interactive TV, home-shopping, video conferences, telephone conferences, interfacing to imaging systems, automatic telephone call charge-backs ("900" numbers), and other telecommunication services which may not yet be invented at this time. The current preferred embodiment of the invention is for subscriber account management for cable television services.

Network-Based Marketing: Identifying Likely Adopters via Consumer

Abstract: Network-based marketing refers to a collection of marketing techniques that take advantage of links between consumers to increase sales. We concentrate on the consumer networks formed using direct interactions (e.g., communications) between consumers. We survey the diverse literature on such marketing with an emphasis on the statis- tical methods used and the data to which these methods have been applied. We also provide a discussion of challenges and opportunities for this burgeoning research topic. Our survey highlights a gap in the literature. Because of inadequate data, prior studies have not been able to provide direct, statistical support for the hypothesis that network linkage can directly affect product/service adoption. Using a new data set that represents the adoption of a new telecommunications service, we show very strong support for the hypothesis. Specifically, we show three main results: (1) "Network neighbors"—those consumers linked to a prior customer—adopt the service at a rate 3-5 times greater than baseline groups selected by the best practices of the firm's marketing team. In addition, analyzing the network allows the firm to acquire new customers who otherwise would have fallen through the cracks, because they would not have been identified based on traditional attributes. (2) Statistical models, built with a very large amount of geographic, de- mographic and prior purchase data, are significantly and substantially improved by including network information. (3) More detailed network information allows the ranking of the network neighbors so as to permit the selection of small sets of individuals with very high probabilities of adoption.

Designing an on-demand multimedia service

Abstract: A quantitative study of techniques for designing a high-performance multiuser multimedia on-demand information service is presented. The problem of maintaining continuity of playback of each media stream in the presence of multiple subscriber requests is formulated, and admission control algorithms that permit a multimedia server to satisfy the maximum number of subscribers simultaneously are presented. A feedback technique in which a multimedia service uses lightweight messages called feedback units that are transmitted back to it by subscribers' mediaphones to detect asynchrony among them and steer them back to synchrony thereafter is presented. The feedback technique guarantees synchronous playback of media streams transmitted by the multimedia server to subscribers over metropolitan-area networks. >
