The degree of agility in a technology company’s strategy, management, and leadership

Vanharanta H., Kantola J., Markopoulos E., Salo M., Einolander J., Hanhisalo T.

Management and Production Engineering Review

2018

Vol. 9, No. 4

129--137

Agility is a concept and practice with significant importance in managing and leading added value in products, services, projects, and organizations, although it’s usage can also be very risky due to its degree of fuzziness, if not properly understood and defined. This research re-defines agility, emphasizes the need for ontologies for its management and leadership applications and uses a new type of fuzzy logic-based software to measure the degree of agility inside a technology company. In our agility research, various definitions of agility were first gathered and presented for the creation of an agility ontology through a mind map, revealing the main characteristics of agility. Then as part of the Co-Evolute theory and methodology, the first agility ontology was developed as well as the first software application that evaluates the degree of agility in an organization. The application includes statements on which the respondents give opinions in their situation concerning the current and future desired states of agility and its importance in an evaluative way. Today the application has been fully tested in the real world and we have obtained the first test results. The positive verification and validation of the method are shown in this article.

Utilization of a neutral wire filter inductor in a three-leg four-wire active power filter

Pettersson S., Salo M., Tuusa H.

Electrical Power Quality and Utilisation. Journal

2005

Vol. 11, nr 2

Three-leg active power filter topology is the cost effective solution implementing a four-wire active power filter but it has some disadvantages compared to four-leg topology. The lack of a neutral wire filter inductor results in larger filter losses and therefore the efficiency of the topology is impaired. The neutral wire filter inductor is typically used with the four-leg four-wire active power filter topology and significantly reduces switching frequency current ripple. In this paper the suitability of a neutral wire filter inductor for the three-leg topology is studied. The performance of three-leg topology with a neutral wire filter inductor is studied through computer simulations and laboratory tests. The results indicate that the use of the neutral wire filter inductor clearly improves the performance of three-leg topology.
