Cloning and training collective intelligence with generative adversarial networks
2021
Industry 4.0 and highly automated critical infrastructure can be seen as cyber‐physical‐social systems controlled by the Collective Intelligence. Such systems are essential for the functioning of the society and economy. On one hand, they have flexible infrastructure of heterogeneous systems and assets. On the other hand, they are social systems, which include collaborating humans and artificial decision makers. Such (human plus machine) resources must be pre‐trained to perform their mission with high efficiency. Both human and machine learning approaches must be bridged to enable such training. The importance of these systems requires the anticipation of the potential and previously unknow…
The Continued Innovation-Decision Process : A Case Study of Continued Adoption of Robotic Process Automation
2022
Robotic Process Automation (RPA) originally entered the field of information systems as one of those disruptive innovations that will, among other automation solutions, have a profound effect on job descriptions and work itself in near future. One of the sectors that will be revolutionized – and are in fact already changing – are financial and human resource (HR) services, such as accounting, billing, and payroll services. According to statistics, Finnish companies operating on the administrative and support services sector make little use of service robots. Companies that have initially adopted the technology do not necessary reach its full potential. We explore what factors create challen…
Evolutionary approach for achieving structural coverage in testing IEC 61499 function block systems
2015
The topic of this thesis is automated test generation for control software represented in a specific standard, the IEC 61499. This standard, which is largely based on the concept of function block, establishes a way to design distributed control systems in a visually clear way. The goal of the thesis was to design a test generation approach or a number of such approaches that would produce input test data with high coverage of the implementation of systems under test. Coverage is a measure which expresses the fraction of the system that was exercised at least ones when all tests in a test suite were run on this system. To reach the stated goal, evolutionary computation, a general optimizati…
The Slow Adoption Rate of Software Robotics in Accounting and Payroll Services and the Role of Resistance to Change in Innovation-Decision Process
2022
Robotic process automation (RPA) has by now for years been viewed as a disruptive innovation that will have a significant impact on accounting, HR and payroll services, and yet the rate of adopting the innovation has not reached a level anticipated in past predictions. As several elements have a negative impact on the organization’s rate of adopting RPA, passive resistance to change has a significant impact in the form of constant dithering. Resistance to change can emerge at any stage of the Innovation-Decision process and fluctuate throughout the continued adoption, causing wasted investments, capabilities and resources. peerReviewed
Kyberturvallisuuden hallintajärjestelmän luominen energiayhtiön lämpövoimalaitokseen : CIRP-raportti 2016
2018
Modernin yhteiskunnan toiminta perustuu useiden kriittisten infrastruktuurien yhteistoimintaan. Niiden keskinäinen toimintakyky riippuu yhä enemmän luotettavista sähköisistä järjestelmistä, toimivista tiedonsiirtoverkostoista sekä tiedon luotettavuudesta, eheydestä ja käytettävyydestä toimintaympäristössä, jonka kyberturvallisuusriskejä digitaalisen maailman uhkakuvat jatkuvasti kasvattavat. Suomen sähköntuotannosta lähes kolmannes tuotetaan sähkön ja lämmön yhteistuotantona lämpövoimalaitoksissa. Niiden tuotantoprosessien ohjaus tapahtuu pitkälle automatisoituja ja teknillisesti verkottuneita teollisuuden automaatiojärjestelmiä hyväksi käyttäen. Tämä tutkimusraportti käsittelee energiayhti…
Cyber security in the management of an electricity company
2018
The functioning of a modern society is based on the cooperation of several critical infrastructures, whose joint efficiency depends increasingly on a reliable national electric power system. Reliability is based on functional data transmission networks in the organizations that belong to the power system. Furthermore, reliability is linked to the usability, reliability and integrity of system data in the operating environment, whose cyber security risks are continuously augmented by threatening scenarios of the digital world. In Finland, the production of electricity is in various ways decentralized, which contributes to the reliability of the power system. Finland has about 120 enterprises…
On automatic algorithm configuration of vehicle routing problem solvers
2019
Many of the algorithms for solving vehicle routing problems expose parameters that strongly influence the quality of obtained solutions and the performance of the algorithm. Finding good values for these parameters is a tedious task that requires experimentation and experience. Therefore, methods that automate the process of algorithm configuration have received growing attention. In this paper, we present a comprehensive study to critically evaluate and compare the capabilities and suitability of seven state-of-the-art methods in configuring vehicle routing metaheuristics. The configuration target is the solution quality of eight metaheuristics solving two vehicle routing problem variants.…
Standardit, ohjeet ja suositukset osana teollisuusorganisaatioiden kyberturvallisuuden hallintaa : CIRP-raportti 2017
2018
Standardisointi mahdollistaa organisaatiossa yhteisten toimintatapojen hakemisen. Se helpottaa myös organisaation toimintaa sen keskeisten sidosryhmien, kuten viranomaisten, muun elinkeinoelämän ja kuluttajien kanssa. Lisäksi standardisoinnilla edistetään tuotteiden yhteensopivuutta ja turvallisuutta, suojellaan kuluttajaa ja ympäristöä sekä helpotetaan kotimaista ja kansainväistä kauppaa. Tämä raportti on katsaus standardeihin, ohjeisiin ja suosituksiin, joiden koetaan olevan hyödyllisiä teollisuusyrityksen toiminnassa sen automaatiojärjestelmien (ICS-järjestelmä) kyberturvallisuuden näkökulmasta katsottuna. Katsauksessa pääpaino on dokumenteissa, jotka hyödyntävät teollisuusyrityksen toim…
Computer mediated organizational memory for process control : moving CSCW research from an idea to a product
2002
This study provides a rare examination of the development process of collaborative applications from a research idea into a commercially introduced software. The research challenge here is to investigate how to enhance the communication and information sharing in process control environments with computerized tools. Such environments can be characterized by time-criticality, complexity and turbulence. The study deploys the technological, human, and business approaches into a research driven system design. It draws upon experiences of a more than six-year longitudinal and constructive research project focusing on the design, adoption and tailoring of computer support (organizational memory) …
