Simulation models in eGovernment using system dynamics: A literature survey

2016

System Dynamics (SD) is a method to build simulation models using computers, to study the behaviour of systems, and apply what-if scenarios aiming at achieving optimal policy design. To have an overview of the current state-of-the-art of SD use in the eGovernment field; we have surveyed related literature. Our main goal is to uncover the possibilities for future research by clarifying the shortages. The identified literature is not very large. In most of the literature, SD models use was limited to SD practitioners. We discovered low usage of Group Model Building and workshops despite their usefulness in involving non-SD practitioners in the model building process. Additionally, there is a …

Using Group Model Building and System Dynamics Modeling in Health Care Quality Assessment

Introduction & Research Aim Drawing from previous research on performance management, arguing that measurement systems in the public sector sometimes lead to harmful outcomes (Bianchi, 2010, 2015; Bivona & Montemaggiore, 2010), the purpose of this study is to assess the long-term dynamic impact of “ESY-net” (i.e. the Greek public hospitals' national performance measurement system) on the quality of healthcare services. Methods As hospital quality is a quite broad and abstract concept, perceived differently by different stakeholders, we will take a systemic view (Meadows, 2008; Sterman, 1994) and use Group Model Building (GMB) (De Gooyert, 2016, 2018; De Gooyert, Honingh, & Van G…

Dynamic Modeling and Driving Cycle Prediction for a Racing Series Hybrid Car

2014

International audience; This paper presents Noao, a plug-in series hybrid racing car equipped with an engine/generator set as range extender. To determine the velocity profile, i.e., performance of the car and its power profile, a dynamic model for this car is developed using pedal position as input. This value is easy to measure, representative for race cycles, and presents a novelty. The model is validated with the results from experiments. An analysis based on the map of Magny-Cours racing circuit and drivers pedal action on certain zones of the circuit is formulated and is used as a prediction tool to determine drivers inputs on other racing circuits and generate driving schedules. The …

Applying system dynamics to foster organizational change, accountability and performance in the public sector: A case-based Italian perspective

2010

The goal of this paper is to discuss the role System Dynamics (SD) can play to enhance performance improvement in the public sector. It is remarked how SD can help decision makers to properly perceive the boundaries of the relevant system underlying observed phenomena. To this end, three real cases are analysed to show how SD can facilitate a better understanding of the relationships between the political and the organisational system in the public sector, and how to promptly attain efficiency and improve outcome, given the constraints that the institutional and political systems constitute. The goal of this paper is to discuss the role System Dynamics (SD) can play to enhance performance i…

Exploring the relationships between tangible and intangible resources in a learning alliance dynamics: comment on the paper by Kapmeier

2008

Kapmeier (2008) focuses his research on common learning and firms’ opportunistic behaviour in learning alliances. A strategic alliance, as clearly stated by Gulati (1998, p. 293) is a voluntary arrangement between firms to exchange and share knowledge as well as resources with the intent of developing processes, products or services. This is a relevant topic not only for those firms that operate in industries characterized typically by high RD Larsson et al., 1998). Furthermore, this literature essentially takes a static view and it often neglects the postformation dynamics of alliances (Koza and Lewin, 2000; Das and Teng, 2001). Some key questions not yet profoundly investigated are: how c…

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…

Reflections on the 8th European System Dynamics Workshop

2019

The purpose of this paper is to comment on the main scientific and social outcomes produced by the 8th European System Dynamics Workshop on “Modeling Sustainability Pathways”—hosted by the NOVA School of Science and Technology, and the Center for Environmental and Sustainability Research in Lisbon on June 1‐2, 2017.

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…

The effect of inventory record inaccuracy in information exchange supply chains

2015

Abstract The goal of this paper is to quantify the impact of Inventory Record Inaccuracy on the dynamics of collaborative supply chains, both in terms of operational performance (i.e. order and inventory stability), and customer service level. To do so, we model an Information Exchange Supply Chain under shrinkage errors in the inventory item recording activity of their nodes, present the mathematical formulation of such supply chain model, and conduct a numerical simulation assuming different levels of errors. Results clearly show that Inventory Record Inaccuracy strongly compromises supply chain stability, particularly when moving upwards in the supply chain. Important managerial insights…

HOME COUNTRY INSTITUTIONAL EFFECTS ON INTERNATIONAL COMPETITIVENESS

2023

La qualità delle istituzioni di un Paese ha un effetto significativo sulla sua performance economica. Istituzioni forti possono garantire un'allocazione efficiente delle risorse, ridurre l'incertezza e gli attriti e favorire il coordinamento tra gli agenti economici. Al contrario, istituzioni deboli determinano una riduzione degli investimenti, un rallentamento della crescita della produttività e una minore crescita del PIL. Buone istituzioni favoriscono le sinergie tra gli investimenti diretti esteri e le imprese locali, nonché le ricadute di produttività. Al contrario, istituzioni poco sviluppate possono interferire con le attività produttive e impedire lo sfruttamento delle ricadute di c…
