E-Services and Productivity
Services are presently recognized as a source of productivity growth and dynamism in the economy. However, in the public sector, these productivity improvements enabled by services are not easy to recognize. On the contrary, negative productivity effects related to Information and Communication Technologies (ICT) investments have been reported. In this paper, we first consider how ICT changes services and how the productivity effects of these changes can be evaluated. Then, we analyze two cases, the Finnish Tax Administration and the Helsinki Central University Hospital Stroke Unit, and draw conclusions about the ICT investments and productivity. Continue reading
Method for Throughput Maximization of Multiclass Networks with Flexible Servers
Tässä artikkelissa tutkitaan joustavia erityyppisiä palvelimia käyttävän moniluokkaverkon läpäisyä, kun verkon solmuissa olevien palvelinten osaamisluokat ja kokonaismäärät noudattavat yleisiä rajoitusehtoja. Continue reading
Optimal Resource Allocation in Multiclass Networks
Tässä artikkelissa tutkitaan joustavia erityyppisiä palvelimia käyttävän moniluokkaverkon resurssiallokaatiota, kun verkon solmuissa on erityyppisiä palvelimia ja palvelinten kokonaismäärät noudattavat yleisiä rajoitusehtoja. Continue reading
Real-time wireless acquisition of process data
Tässä tutkimuksessa tarkastellaan automaattista työprosessien mittaamista käyttäen hyväksi tiedonlouhintaa. Mittaustieto kerätään reaaliajassa Bluetooth-antureista ja saatu lokitieto analysoidaan. Continue reading
Real-time Process Data Acquisition with Bluetooth
Healthcare workflow processes are extremely complicated. Surveys and interviews are a common but a rather expensive way of conducting process research. This paper elaborates a new approach based on wireless technologies for data gathering of healthcare processes. Continue reading
Developing a Real-Time Data Acquisition System for Automatic Process Measurement
As the population aging is a global and unalterable trend, and the whole society is lacking of productive workforce to provide healthcare services, there is a pressure to develop smart services to support the elderly persons live a more independent life and improve the quality of open healthcare. This paper combines together the concepts of smart living environment and process management, we discuss a novel method called automatic process measurement that uses wireless technologies to collect process data for process mining and process analysis.
