Dealing with Multi-Level Governance and Wicked Problems in Urban Transportation Systems: The Case of Palermo Municipality

2015

Italian New Public Management (NPM) has been mainly characterized by a political orientation toward power decentralization to local governments and privatization of public companies. Nowadays, local utilities in Italy are often run by joint stock companies controlled by public agencies such as Regional and Municipal Administrations. Due to this transformation, these companies must comply with a set of diverse expectations coming from a wide range of stakeholders, related to their financial, competitive and social performance. Such fragmented governance increases the presence of “wicked” problems in the decision-making sphere of these entities. Given this multi-level governance structure, ho…

Strategic leadership in cyber security, case Finland

2020

Cyber security has become one of the biggest priorities for businesses and governments. Streamlining and strengthening strategic leadership are key aspects in making sure the cyber security vision is achieved. The strategic leadership of cyber security implies identifying and setting goals based on the protection of the digital operating environment. Furthermore, it implies coordinating actions and preparedness as well as managing extensive disruptions. The aim of this article is to define what is strategic leadership of cyber security and how it is implemented as part of the comprehensive security model in Finland. In terms of effective strategic leadership of cyber security, it is vital t…

Network-based H∞ output feedback control for uncertain stochastic systems

2013

This paper investigates the problem of network-based Floc, output feedback control for a class of stochastic nonlinear systems. A novel model is proposed to describe the systems taken into two sides of communication channels in the network environment, which is more general than one side of communication channel. The design procedure of observer-based controller is presented, which, guarantees the asymptotic stability in the mean square of the resulting closed-loop system with an H-infinity performance. Finally, a crane example is utilized to show the effectiveness and potential of the developed techniques. Refereed/Peer-reviewed

Optimizing the level of service quality of a bike-sharing system

2016

Public bike-sharing programs have been deployed in hundreds of cities worldwide, improving mobility in a socially equitable and environmentally sustainable way. However, the quality of the service is drastically affected by imbalances in the distribution of bicycles among stations. We address this problem in two stages. First, we estimate the unsatisfied demand (lack of free lockers or lack of bicycles) at each station for a given time period in the future and for each possible number of bicycles at the beginning of the period. In a second stage, we use these estimates to guide our redistribution algorithms. Computational results using real data from the bike-sharing system in Palma de Mall…

A Framework for Assessing the Condition of Crowds Exposed to a Fire Hazard Using a Probabilistic Model

2014

Published version of an article in the journal: International Journal of Machine Learning and Computing. Also available from the publisher at: http://dx.doi.org/10.7763/IJMLC.2014.V4.379 open Access Allocating limited resources in an optimal manner when rescuing victims from a hazard is a complex and error prone task, because the involved hazards are typically evolving over time; stagnating, building up or diminishing. Typical error sources are: miscalculation of resource availability and the victims’ condition. Thus, there is a need for decision support when it comes to rapidly predicting where the human fatalities are likely to occur to ensure timely rescue. This paper proposes a probabil…

A framework for a network-level performance measurement system in SME networks

2008

The present study aims to present a theoretical framework for a network-level performance measurement system. The suggested framework for the performance measurement system is composed of the factors that enable and cause the productivity and profitability of the network form of organisation. The framework developed in this study can be divided into six subdimensions: (1) network culture, (2) resources and competences, (3) models of action, (4) internal processes, (5) customer perspective and (6) financial indicators of the network. We argue that this framework provides research opportunities to study the performance of the network form of organisation; but even more importantly, it provide…

Improving performance and fostering accountability in the public sector through system dynamics modelling: From an ‘external’ to an ‘internal’ perspe…

2010

This paper aims to outline the benefits justifying a tailored approach to System Dynamics (SD) modelling in the public sector, to improve performance and foster decision makers' accountability. The need of combining an ‘internal’ with an ‘external’ perspective (in respect to decision makers) in developing SD models is claimed. Different levels of intervention (i.e. macro, micro and meso) are discussed. Two case studies are analysed. The first one demonstrates how a dynamic resource-based view (DRBV) can support an analysis of the impact of back and front office units on a public sector organization's performance drivers. The second case shows how SD modelling based on a DRBV can also be app…
