Bok (populärvet., debatt m.m.)abstract
- How on Earth did this happen? The question is not infrequent, but more to the point, it?s unnecessary. It arises because in many cases people haven?t thought things through beforehand. Yes, sometimes people can be unlucky, but far from every time that things go awry; bad luck is never so consistent - by definition. Thinking things through properly beforehand might seem a fairly obvious requirement for making a good decision, but startlingly often, even critical decisions are made without any in depth analysis. Well, there may have been some background data lying around somewhere, but not much is done with it. Though it's easy to blame authoritarian leadership or the like, poor decision making is far more usually due to not really knowing what to do with the available information, whether it's sufficient and what else needs to be known There?s nothing weird or idiotic about today?s decision makers, but there often is about the tools and methods available to them. It would be more accurate to say that many decision makers have been lead astray regarding their remit and capacity, but fortunately with structured decision processes they can be guided back on track far more easily than had they been as dim- witted as some of their decisions would indicate.Businesses introduce various BI solutions both timely and untimely, but what most of them don't have is any kind of methodology by which to deal with decisions. With no processes, knowledge, techniques or tools, they soon come to grief. Happily this is fairly easy to remedy.Decision processes and decision methods can be greatly improved. In this book we simply explain how to go about it.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- The Swedish city of Örebro has since long faced complex problems with poor water quality in a local river. This problem is a typical example of a regional decision problem, since there are several different stakeholders that might be affected, and there are different views on the need for, and effect of, different measures. The problems also strongly relate to the environmental condition of the river and involve other municipalities as well. In this chapter, we describe how to address this problem using an implementation of a systematic democratic deci-sion process for enhancing the transparency and the decision quality in itself. The process is in conformity with common democratic processes, but with higher em-phasis on accuracy and precision and on the interaction between civil servants and decision makers. A main issue here is to clearly separate the various views in-volved in these processes from the actual facts and, at the same time, facilitate input from various stakeholders. Therefore, we allow for modelling of outcomes based on different preferences and facilitate an elicitation process where views are extracted and combined with basic data from the background investigations preceding the decision. The process is divided into two stages. The first one is em-phasized in this chapter and concerns the internal democracy, i.e. the formulation and refinement of the original and extended decision problems and the interaction between politicians and civil servants, while the second stage deals with the external democracy, i.e. the communication with the public, where communication channels directed towards citizens will be formed.

On the Use of ISO 2859 Sampling by Attributes as Quality Control of Cleared Land in Humanitarian Demining
- 2012
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- In the International Mine Action Standards (IMAS) standards for mine actions are defined. One of these describes how quality control is conducted. The inspections and sampling of cleared land are based on the ISO 2859 standard. This standard uses sampling by attributes, i.e. a sample is taken from a lot of produced units andthe lot is rejected if the number of non-conforming items exceeds a threshold. In this report the criticism levelled against ISO 2859 is investigated and particularly the cost and informative value of using ISO 2859 as it is being applied through IMAS. A quantitative investigation of the sampling plans specified in IMAS indicate that the value of sampling is highly dependent on the size of the lot andthe actual quality level and that the sampling plans are not optimal. If samplingshould be conducted seen from a cost perspective taking its informative value into account, this value is highly dependent on the expected quality of clearance, to what degree this quality is uncertain, and the lot size. The IMAS is inflexibletowards this and is not well calibrated in order to weigh the informative value ofsampling against its costs. We therefore propose a revision of IMAS 09.20 facilitating a more cost effective approach to sampling and quality control. Of importance would be to relatethe cost of sampling to opportunity costs such as performing clearance. This may also consider how to distribute the cost of sampling across cost carriers, stimulating the clearance organisations to obtain and maintain a high quality. Further, it isnot clear how to account for both the producer’s and the consumer’s risk in terms of quality in the mine action domain. Investigating methods for aggregating thesein a model for identifying a feasible sampling plan might be valuable in order to perform cost effective quality control while maintaining the objective of releasingsafe land.

Business Intelligence as Decision Support in Business Processes : An Empirical Investigation

Konferensbidrag (refereegranskat)abstract
- Our concern in this paper is the role of business intelligence systems and the perceived business value of implemented systems and their contribution to facilitate the fulfilment of organizational goals. The study builds upon a survey answered by 43 respondents from different large companies in Scandinavia. The survey used questions on how visions, objectives, strategies are supported by BI systems, on how business values are derived from such systems, and on how design and implementation issues affect the solutions. The overall conclusion of the study is that there are markedly different levels of problems in the areas, most problems being found in integration of BI information and decision processes, and that there is room for large improvements and further work within everything from implementation to requirements engineering for business intelligence decision support systems.

Employing Cardinal Rank Ordering of Criteria in Multi-Criteria Decision Analysis
- 2012

Konferensbidrag (refereegranskat)abstract
- The elicitation of preference information in multi-criteria decision analysis (MCDA) processes and the lack of practical means supporting it is a significant problem in real-life applications of MCDA. The issues at hand are problematical in a multitude of ways, but some of these issues may be remedied by accepting weaker input statements from decision-makers than what is most commonly needed, yet being able to utilize these statements for decision evaluation. In this paper, we propose a fast and practically useful weight elicitation method, which builds on the ideas of rank-order methods, but in addition take imprecise cardinal information into account.

Konferensbidrag (refereegranskat)abstract
- This paper presents a web-application supporting structured decision modelling and analysis. The application allows for decision modelling with respect to different preferences and views, allowing for numerically imprecise and vague background probabilities, values, and criteria weights, which further can be adjusted in an interactive fashion when considering calculated decision outcomes. The web-application is based on a decision tool that has been used in a large number of different domains over the last 15 years, ranging from investment decision analysis for companies to public decision support for local governments.
