A new project management approach for R&D software projects in the automotive industry - continuous V-model

2017

Most current work activities in R&D centres are innovative and dynamic, with project management acting as the discipline that governs them. The improvement of PM methods has become a necessity due to the following main factors: classical methodologies are increasingly difficult to apply, cutbacks in project duration are requested by organisations and customers, demands for product quality are continuously expanding. The paper examines how PM concepts are used in developed R&D projects, based on the V-model approach. It also introduces an enhanced new approach called Continuous V-model - CVM, based on agile concepts. The model has been applied on a real automotive R&D project and the resulte…

Versatile tool for competence management - an e-portfolio management system for higher education in applied sciences

2011

In the line of outcome based education and transferability of credits, we study a Higher Education case and propose an e-Portfolio solution as a versatile tool for assessment tasks. The solution tackles the problems firstly, of accreditation of prior achievements from both institutional and experiential learning. Secondly, the developed tool carries the process of learning outcome definitions management (derived from the real employment world), and the learner self-assessment and self-reflection as well as the guidance and support for these. The e-Portfolio management system, ePofo, supports the identification, assessment, recognition and accreditation of prior learning achievements and lea…

A Stochastic Soft Constraints Fuzzy Model for a Portfolio Selection Problem

2006

The financial market behavior is affected by several non-probabilistic factors such as vagueness and ambiguity. In this paper we develop a multistage stochastic soft constraints fuzzy program with recourse in order to capture both uncertainty and imprecision as well as to solve a portfolio management problem. The results we obtained confirm the studies carried out in literature addressed to integrate stochastic and possibilistic programming.

Contingent claim valuation in a market with different interest rates

1995

The problem of contingent claim valuation in a market with a higher interest rate for borrowing than for lending is discussed. We give results which cover especially the European call and put options. The method used is based on transforming the problem to suitable auxiliary markets with only one interest rate for borrowing and lending and is adapted from a paper of Cvitanic and Karatzas (1992) where the authors study constrained portfolio problems.

The Economic Value of Volatility Transmission Between the Stock and Bond Markets

2008

This study has two main objectives. Firstly, volatility transmission between stocks and bonds in European markets is studied using the two most important financial assets in these fields: the DJ Euro Stoxx 50 index futures contract and the Euro Bund futures contract. Secondly, a trading rule for the major European futures contracts is designed. This rule can be applied to different markets and assets to analyze the economic significance of volatility spillovers observed between them. The results indicate that volatility spillovers take place in both directions and that the stock-bond trading rule offers very profitable returns after transaction costs. These results have important implicatio…

Fuzzy Mathematical Programming for Portfolio Management

2000

The classical portfolio selection problem was formulated by Markowitz in the 1950s as a quadratic programming problem in which the risk variance is minimized. Since then, many other models have been considered and their associated mathematical programming formulations can be viewed as dynamic, stochastic or static decision problems. In our opinion, the model formulation depends essentially on two factors: the data nature and the treatment given to the risk and return goals. In this communication, we consider several approaches to deal with the data uncertainty for different classical formulations of the portfolio problem. We make use of duality theory and fuzzy programming techniques to ana…

Exploring the Relationship between Information Technology Infrastructure Library and Process Management: Theory Development and Empirical Testing

2014

This paper investigates whether information technology (IT) departments that implement the IT Infrastructure Library (ITIL) processes also employ process management. This is a pertinent issue, as ITIL not only implies a time-limited program for redesigning vital IT processes according to best practices but a complete transformation to ITIL also implies that processes are managed on a daily basis. Without process management, ITIL will not be a success beyond its initial implementation. A survey of 444 Nordic ITIL experts was conducted to examine if there is a correlation between the implementation of ITIL processes and process management. The results are unambiguous and promising for sustain…

Optimal Dynamic Portfolio Risk Management

2016

Numerous econometric studies report that financial asset volatilities and correlations are time-varying and predictable. Over the past decade, this knowledge has stimulated increasing interest in various dynamic portfolio risk control techniques. The two basic types of risk control techniques are: risk control across assets and risk control over time. At present, the two types of risk control techniques are not implemented simultaneously. There has been surprisingly little theoretical study of optimal dynamic portfolio risk management. In this paper, the author fills this gap in the literature by formulating and solving the multi-period portfolio choice problem. In terms of dynamic portfoli…

Strategising IT service management through ITIL implementation: model and empirical test

2015

Research on the Information Technology Infrastructure Library (ITIL) lacks appropriate theories and models that capture the distinct characteristics and implications of the ITIL implementation practice. The purpose of this study is to close this gap. Based on a literature review, we develop and empirically validate a theoretical model: the ITIL Implementation Project Model. The model includes significant antecedents, which provide a foundation upon which an effective ITIL implementation project can be built, as well as the pertinent effects of implementing ITIL. The results contribute to the current research stream on the strategising of IT service management as well as to an improved under…
