This paper presents a method for dynamic effort estimation, together with its supporting tool, and the experimental validation on a renewal project of a very aged software system. Method characteristics such as dynamic tuning and fine granularity allows the tool to quickly react to process variations. The experimental validation shows how the combination of meaningful predictors and fine grain ...

In this paper we consider heavy tailed Markov renewal processes and we prove that, suitably renormalised, they converge in law towards the α-stable regenerative set. We then apply these results to the strip wetting model which is a random walk S constrained above a wall and rewarded or penalized when it hits the strip [0,∞) × [0, a] where a is a given positive number. The convergence result tha...

Renewal-reward processes are used to provide a framework for the mathematical description of single-molecule bead-motor assays for processive motor proteins. The formulation provides a more powerful, general approach to the fluctuation analysis of bead-motor assays begun by Svoboda et al. (Proc. Natl. Acad. Sci. USA 91(25):11782, 1994). Fluctuation analysis allows one to gain insight into the m...

This thesis deals with the reliability and maintenance of structures that are damaged by shocks arriving randomly in time. The degradation is modeled as a cumulative stochastic point process. Previous studies mostly adopted expected cost rate criterion for optimizing the maintenance policies, which ignores practical implications of discounting of maintenance cost over the life cycle of the syst...

Transaction banking is changing in a fast pace due to digitalization, changes in regulation, new competition in the market etc. This acronym VUCA describes this environment; Volatility, Uncertainty, Complexity and Ambiguity. Due to changes in technology, politics and economics strategic renewal is critical to ensure long term survival. Middle managers play a vital role within strategic renewal ...
