Rumour propagation: an operational research approach by computational and information theory Guerbuez, Burcu; Mawengkang, Herman; Husein, Ismail; Weber, Gerhard Wilhelm (Springer Science and Business Media LLC, 2021-01-01) Rumours are a kind of information that has a impact on social life and economies, which spread quickly and widely, especially, via internet. Recently, the spread of information affects our daily lives due to the increasing number of social media users. Rumours are defined in social areas which are delivered by gossips, fake news, marketing, social media all the way even to revolutions. In this paper, we study the dynamics of a rumour propagation model with a numerical approach. By using an algorithmic techn...
On the classical Maki-Thompson rumour model in continuous time Belen, Selma; Kropat, Erik; Weber, Gerhard Wilhelm (Springer Science and Business Media LLC, 2011-03-01) In this paper, the Maki-Thompson model is slightly refined in continuous time, and a new general solution is obtained for each dynamics of spreading of a rumour. It is derived an equation for the size of a stochastic rumour process in terms of transitions. We give new lower and upper bounds for the proportion of total ignorants who never learned a rumour and the proportion of total stiflers who either forget the rumour or cease to spread the rumour when the rumour process stops, under general initial condit...

Public R&D project portfolio selection problem with cancellations ÇAĞLAR, Musa; Gürel, Sinan (Springer Science and Business Media LLC, 2017-07-01) In this study, we address a public R&D project portfolio selection problem with project cancellations. For several reasons, a funded R&D project may be halted before finishing the planned research. When a project is canceled, most of its budget is usually unused and also some of the spendings can return to the funding organization. In the call-based R&D programs, usually project selection decisions are made in one go, and, in the current call, it is not possible to award new projects with the unused budget....
Cooperative games under interval uncertainty: on the convexity of the interval undominated cores Branzei, R.; ALPARSLAN GÖK, Sırma Zeynep; Branzei, O. (Springer Science and Business Media LLC, 2011-12-01) Uncertainty is a daily presence in the real world. It affects our decision making and may have influence on cooperation. Often uncertainty is so severe that we can only predict some upper and lower bounds for the outcome of our actions, i.e., payoffs lie in some intervals. A suitable game theoretic model to support decision making in collaborative situations with interval data is that of cooperative interval games. Solution concepts that associate with each cooperative interval game sets of interval allocat...
