Investigating key decision problems to optimize the operation and maintenance strategy of offshore wind farms

This paper investigates three decision problems with potential to optimize operation and maintenance and logistics strategies for offshore wind farms: the timing of pre-determined jack-up vessel campaigns; selection of crew transfer vessel fleet; and timing of annual services. These problems are compared both in terms of potential cost reduction and the stochastic variability and associated uncertainty of the outcome. Pre-determined jack-up vessel campaigns appear to have a high cost reduction potential but also a higher stochastic variability than the other decision problems. The paper also demonstrates the benefits and difficulties of considering problems together rather than solving them in isolation.

En jämförelse av upplevd produktivitet samt arbetstillfredsställelse mellan aktivitetsaserade och traditionella kontor.

Purpose: The aim with this study is to compare perceived productivity and job satisfaction between activity based offices and traditional offices. The goal is to investigate, through a quantitative comparison, productivity and job satisfaction between the office types, and if generations perceive this differently. Method: The method used in this study is a quantitative method, in form of a questionnaire. The questionnaire used was taken from a study made by Sahlström and Severin (2015) at the Royal Institute of Technology in Stockholm. The same questionnaire was taken because it had already been quality assured and had good content for the survey. Four IT companies were included in the study. Two of them had activity based offices and two of them had traditional office type. Literature review has also been a method in order to get a deeper understanding of the subject. Findings: The results of the study show that there are differences between the two office types in perceived productivity and job satisfaction. The traditional office type showed the best results. However, this result can be discussed since the two traditional offices differed widely in their responses. The results also show that there are differences between the generations experiencing productivity and job satisfaction of the various offices. The elder generation, Baby boomers, shows better results on the traditional office type and the younger generation, Generation Y, shows better results on the activity based offices. Implications: One conclusion to be drawn from this is that employees at traditional offices are more satisfied with their working place and experience increased productivity than employees on activity based offices. However, these results may be due to other factors than how the office environment affects the employees. Therefore, these results will not be recommended. Another conclusion is that the Baby boomers are experiencing higher productivity and job satisfaction of traditional office and Generation Y experiences higher productivity and job satisfaction on activity based office. These results can be recommended. Limitations: The limitations of this study are to examine only IT companies in Sweden with a maximal amount of employees of 150 persons. The results are, apart from the scattered results in the first issue, generally valid and can be applied to other IT companies. To succeed fully applicable results, a survey with more companies involved had been better. Then, detections of anomaly would easier have been discovered and possible disregards of certain results could have been done. Keywords: Perceived productivity - Self-rated assessment of employees on their own productivity. Traditional offices - In this work traditional offices includes cell offices and shared rooms. Activity based offices - Office where employees have no fixed work place and there are often zones to support different types of working.
