In this paper, we detail our WhiteDolphin agent that was designed for the Trading Agent Competition (TAC) Travel game. Specifically, we employed the multi-layered IKB framework to design our strategy, and describe the intricate cogs involved at the different layers in this complex decisionmaking process. We focus, in particular, on WhiteDolphin’s strategic behaviour when bidding in the differen...

With an ageing population and improved diagnostic modalities, the number of patients with valvular heart disease is dramatically increasing. Considering projected changes in the age distribution, a further accentuation of this trend can be expected and this may indeed be considered “the next cardiac epidemic”.1 Obviously, we are faced with more complex decisions in patients with advanced age an...

This article reviews recent developments in the theory of committee decisionmaking. A committee consists of self-interested members that make a public decision by aggregating imperfect information dispersed among them according to a pre-specified decision rule. We focus on costly information acquisition, strategic information aggregation, and rules and processes that enhance the quality of the ...

We present a token-level decision summarization framework that utilizes the latent topic structures of utterances to identify “summaryworthy” words. Concretely, a series of unsupervised topic models is explored and experimental results show that fine-grained topic models, which discover topics at the utterance-level rather than the document-level, can better identify the gist of the decisionmak...

Evaluation for ranking is very useful for users in their decisionmaking process when they want to select some item(s) from a large number of items using their personal preferences. In this paper, we will focus on the evaluation of Japanese traditional crafts, in which product items are assessed according to the so-called Kansei features by means of the semantic differential method. In particula...

A large literature shows that strategic interactions among actors with conflicting objectives can cause the political process to produce outcomes that lower welfare. This paper investigates an alternative explanation of such outcomes: if individuals’ errors in assessing the likely effects of proposed policies are correlated, democratic decisionmaking can produce welfare-reducing outcomes even i...

Data warehouses and Online Analysis Processing (OLAP) have acknowledged and efficient solutions for helping in the decisionmaking process. Through OLAP operators, online analysis enables the decision-maker to navigate and view data represented in a multi-dimensional manner. But when the data or objects to be analyzed are complex, it is necessary to redefine and enhance the abilities of the OLAP...

Product innovation within strategic alliances differs from product innovation within firms due to coordination problems with respect to decision making. This exploratory study, drawing on alliance research, strategic decisionmaking research and product innovation literature explains these problems at the level of product innovation projects in dyadic strategic alliances. In particular, the empi...

Today, process control and monitoring are evolving to include plant safety and availability management, on-line diagnosis and maintenance policy. Human operators are at the highest hierarchical level in the organization of the control system. Supervision aims are to assist control operators in their decisionmaking tasks, to help them understand and identify operating situations underway in a ma...

In the decision-making process of city emergency evacuation, due to limited resources and time, and changing situation, it is difficult to make emergency decision accurately and efficiently. Therefore, in this paper, the city emergency evacuation decisionmaking model based on extended OODA loop is constructed. Through task determination and task allocation of emergency evacuation, the emergency...
