Incorporating stand level risk management options into forest decision support systems
2018
Aim of study: To examine methods of incorporating risk and uncertainty to stand level forest decisions. Area of study: A case study examines a small forest holding from Jonkoping, Sweden. Material and methods: We incorporate empirically estimated uncertainty into the simulation through a Monte Carlo approach when simulating the forest stands for the next 100 years. For the iterations of the Monte Carlo approach, errors were incorporated into the input data which was simulated according to the Heureka decision support system. Both the Value at Risk and the Conditional Value at Risk of the net present value are evaluated for each simulated stand. Main results: Visual representation of the er…
Ecotoxicity assessment of boreal lake sediments affected by metal mining: Sediment quality triad approach complemented with metal bioavailability and…
2019
Highlights • Ecological risk assessment of metal-contaminated boreal lakes and sediments. • Sediment Quality Triad complemented with bioavailability and body residue studies. • Toxicity studies for natural sediments with several organisms and endpoints • Adverse effects observed. High variation on results between different methods. • Standard toxicity tests not suitable for testing, too low pH hampers the results. There are several methods for studying metal-contaminated freshwater sediments, but more information is needed on which methods to include in ecological risk assessment. In this study, we compliment the traditional Sediment Quality Triad (SQT) approach – including information on c…
Jatkuvuuden hallinta IT-palveluliiketoiminnassa : case Tieto Oyj
2012
Yhteiskunnan tietoteknistymisen jatkuessa vakaille IT-palveluille on yhä enemmän kysyntää. IT-palvelutoimittajien rooli asiakasyritysten liiketoiminnassa kasvaa, koska liiketoimintaprosessit ovat yhä riippuvaisempia tietojärjestelmistä ja muusta IT-infrastruktuurista. Samanaikaisesti IT-infrastruktuuri kehittyy kompleksisempaan suuntaan, siksi jatkuvuuden hallinnalla, häiriöiden sietokyvyllä ja toipumiskyvyllä on elintärkeä rooli liiketoiminnan ylläpitämisessä. Kaikkia häiriötilanteita ei voi estää, mutta riskien vaikuttavuutta liiketoimintaan voidaan vähentää varautumisen avulla, tällöin puhutaan organisationaalisen häiriönsietokyvyn kasvattamisesta. Häiriötilanteisiin varautumisen lisäksi…
Continuous Requirements Risk Profiling in Information Systems Development
2015
With the increasing adoption of agile, lean, and iterative development methods, information systems development (ISD) has become continuous, meaning that system development moves rapidly from release to release. This means that work practices and challenges that practitioners face have changed. Despite these changes, requirements development is still critical in ISD. However, IS literature is silent on how to manage requirements-related risks in the practice of continuous IS development. To fill this gap, we propose a continuous requirements risk profiling method. The study is informed by design science research methodology, and we apply focus group interviews and a Delphi study for data co…
