Forecasting Market Demand for New Telecommunications Services: An Introduction

by Peter Mcburney, Simon Parsons , 2000

The marketing team of a new telecommunications company is usually tasked with producing forecasts for diverse stakeholders with different needs. Consequently, those outside marketing often do not realize the many reasons for developing forecasts, nor the marketing theory used and the challenges involved in doing so. Based on our three decades of experience working with telecommunications operators around the world we seek to redress this situation by presenting a discussion of the issues involved in demand forecasting for new communication services.

A related approach is to assign subjective degrees of belief to the scenarios themselves =-=[34]-=-, and update these belief assignments as new information arises or as subjective beliefs change. This method, applying a belief function model, uses nonprobability representations for uncertainty firs...

Formalizing Scenario Analysis

Abstract - Cited by 3 (2 self) - Add to MetaCart
We propose a formal treatment of scenarios in the context of a dialectical argumentation formalism for qualitative reasoning about uncertain propositions. Our formalism extends prior work in which arguments for and against uncertain propositions were presented and compared in interaction spaces called Agoras. We now define the notion of a scenario in this framework and use it to define a set of qualitative uncertainty labels for propositions across a collection of scenarios.

Abstract Planning under uncertainty requires the adoption of assumptions about the current and future states of the world, and the preparation of conditional plans based on these assumptions. In any realistic domain, however, there will be an exponential explosion in the number of conditional plans required. One approach to this problem is to articulate a set of scenarios, which together are representative of the possible and/or likely futures. Doing this then creates the challenge of reasoning across the scenarios to decide a course of action. We present an argumentation-based formalism for representing different assumptions in a scenario framework and for reasoning across the resulting scenarios.

...a set of scenarios, which together are representative of the possible and/or likely futures. Doing this then creates the challenge of reasoning across the scenarios to decide a course of action. We present an argumentation-based formalism for representing different assumptions in a scenario framework and for reasoning across the resulting scenarios. Introduction Consider an agent operating in some complex domain, perhaps a robot with the goal of collecting and delivering objects in a factory (Parsons et al. 2000), or telecommunications operator considering how to best provide future services (McBurney & Parsons 2001c). In both these cases, and in many others involving decisions about what to do and how to do it, the decisionmaking entity is faced with what is essentially a planning problem--building a plan from a set of options available to it--but one in which the best plan (and indeed the best goal or set of goals, though we will say little about this matter here) is very dependent upon not just the initial state of the world, but also on how the world evolves over time. The plan that is initially best for the robot may turn out to be sub-optimal when a corridor is found to be blocked, and the plan tha...

The Possibility of Arguability: Combining Multiple Arguments on the Same Topic

by Peter Mcburney, Simon Parsons , 2001

Building on earlier work using dialectical argumentation to represent uncertainty, we consider how the results of different debates on the same topic may be combined coherently. The different debates may be considered as arising under different scenarios about the world. We define a class of uncertainty measures to represent the extent to which a proposition is supported across these alternative scenarios, and we explore their formal properties. Our approach may be considered as expressing the possibility of arguability, analogous to the probability of provability.

Demand for these services was predicted to depend heavily on the extent to which terrestrial mobile communications services would expand, both in terms of customer numbers and the geographic area un...

Scenario planning provides a widely-used means of summarizing the multitude of possible ways in which the future may arrive. Given certain assumptions about the world as it is now in some domain, and assumptions about the factors which may influence it and their inter-relationships, we can articulate an argument for how the present may evolve into the future. With different starting assumptions and different influencing factors, we may articulate alternative arguments for this possible evolution, each corresponding to one or more evolutionary paths.

Recent proposals for computer-assisted argumentation have drawn on dialectical models of argumentation. When used to assist public policy planning, such systems also raise questions of political legitimacy. Drawing on deliberative democratic theory, we elaborate normative criteria for deliberative legitimacy and illustrate their use for assessing two argumentation systems. Full assessment of such systems requires experiments in which system designers draw on expertise from the social sciences and enter into the policy deliberation itself at the level of participants. Keywords: Argumentation, Computer-Mediated Decisions, Decision Support Systems. 1.
