Communication is an important part of any multi-agent system. There are different ways of communicating and they have different effects on a multi-agent system. This project describes and evaluates two different ways of communication, implicit and explicit. To compare the two methods, two experiments have been executed. The result of the experiments have been compared and discussed.

För att ta reda på hur väl en Multi-agent-systems-bot kan stå sig mot andra, icke-MAS-bottar, så har vi implementerat en bot till brädspelet Arimaa. Botten är implementerad i C++ och den kan spela mot andra bottar, eller människor, genom Arimaas officiella hemsida. Syftet har varit att skapa en fullfjädrad bot som både klarar av att spela korrekt, och att spela bra. För att ta reda på om MAS är en bra designfilosofi för Arimaa så har vi utmanat ett antal av de bottar som andra människor skapat och lagt upp på hemsidan. Alla bottarna har under tiden de legat uppe blivit rankade genom tävlingar och utmaningar och flera av dessa har tävlat om stora pengar, vilket betyder att människor har lagt mycket tid på dem.

Problem: The corrugated board industry is highly affected by customer uncertainty, various demands and short delivery times. In combination with a complex multi-step production process managers have to be able to identify bottle-necks and gain knowledge and understanding of how different changes in process will affect the production output. <br/><br/>Purpose: The purpose of this master thesis is twofold, (1) to examine applicability of complexity theory through agent-based modelling on a production process (2) to identify improvement areas in order to increase the production output at SKS production site in Eslöv, by modelling and simulating the production process through an agent-based model. <br/><br/>Method: The chosen method of this study is a combination of a case study and a complex system approach. The empirical data was collected through interviews, observation and document studies which were analysed through an agent-based simulation model.

Intresset för agenter som forskningsområde är någonting relativt nytt. Agenter i sig är en naturlig del av Artificiell intelligens men det är först på senare tid som de hamnat i fokus. Begreppet agent har spridit sig som en löpeld utanför AI-forskningen och kan hittas i många andra områden. Vad detta intresse för agenter kommer ifrån kan debatteras men det är troligtvis dels en följd av att internet visat hur kraftfullt ett distribuerat system kan vara, och att agenter och botar bokar våra biljetter samt söker igenom webbsidor åt oss.Arbetets huvudfråga är att undersöka hur ett intelligent system (för värmedistributionen i ett hus) kan uppnås genom att koppla ihop ett antal agenter med begränsade funktionalitet och distinkta uppgifter. Intelligensen i systemet ska uppnås genom samverkan mellan de olika agenterna.

Deontic Action Logic Multi Agent System (DALMAS) är en typ avmultiagentsystem där agenternas handlingar regleras av ett normativt system. Teorinför DALMAS bygger på deontisk logik, och normer i det normativa systemetuttrycks i termer av Kanger-Lindahls teori om normativa positioner. Syftet meddetta arbete är att försöka reda ut vilka eventuella fördelar ett normativt system kange samt hur man ska kunna skapa effektivt sådant. Går det att skapa ett normsystemsom kan lösa samma problem som ett konventionellt MAS löser? För att kunnajämföra de olika normsystemen har kriterier för hög effektivitet tagits fram.Testresultaten visar bl.a.

This bachelor thesis discusses firefighting and the use of portable fireextinguishers in the salvageof historic artefacts focusing on textiles. It also looks into the use of multi-purpose dry chemicalextinguishers in a textile context and the impact the actual dry-agent has on textiles afterfirefighting.Literature studies, interviews and tests on different textiles were carried out to write this thesis.During the tests textiles were exposed to the dry agent and also to dry agent plus water toinvestigate the difference in residue. After vacuumcleaning it was clear that when the textile wasexposed to dry agent and water it was almost impossible to remove the chemical without rinsingin water.By examining the residue left on the textile using SEM it was possible to see if a textile was aswell decontaminated after vacuum-cleaning as it looks to the eye. We know that the dry agentoften consists of ammonium phosphate which acts corrosively on many materials and one canassume it damages textiles as well after longer exposure.Buildings housing cultural collections are vulnerable as we cannot easily replace ruined materialwith new.

Stratego is a boardgame not very different from chess, that contains hidden information. Because of this, existing programs play at beginner level. The purpose of this thesis is to adjust a minimax algorithm so that it passes the demands of Stratego, and then build a Stratego agent around it. Tests with existing minimax algorithms leads to the development p-e-minimax. This algorithm uses two different values in its nodes to simulate the different information available to the agent and its opponent.

We are working on the development and design of an approach to agents that can reason, react to the environment and are able to update their own knowledge as a result of new incoming information. In the resulting framework, rational, reactive agents can dynamically change their own knowledge bases as well as their own goals. An agent can make observations, learn new facts and new rules from the environment, and then update its knowledge accordingly. The knowledge base of an agent and its updating mechanism has been implemented in Logic Programming. The agent?s framework is implemented in Java.

Franchise theorists have to a large extent failed to keep up with the actual development in global franchise chains. The recent emergence of fast growing multi-unit-franchisees has fundamentally been ignored, and it has been claimed that the new phenomenon can be regarded as a mere replication of the franchisors? structure and control system into sub hierarchies. This study however, suggests that the reality is more complex. Through conducting case studies of two Nordic multi-unit-franchisees, new theories are built explaining how and why control systems are designed the way they are.

This master?s thesis presents experiences from an evaluation of AdApt, a multi- modal, conversational dialogue system, using PARADISE, PARAdigm for Dialogue System Evaluation, a general framework for evaluation. The purpose of this master?s thesis was to assess PARADISE as an evaluation tool for such a system. An experimental study with 26 subjects was performed.

The CASA-paradigm, Computers Are Social Actors, was introduced in the book "TheMedia Equation" by Reeves and Nass. One of their experiments concluded that we tend to be polite to computers in the same way as we are to people. In this study I have replicated Reeves and Nass experiment but instead of a text-based interface I have used a virtual agentin order to find out if we are polite to the agents, or still to the computer. Two experimental setups was conducted. The two setups had a common first part that was carried out on onecomputer with one agent.

This essay puts its focus on examining vendors? underlying decision criterias when choosing an estate agent at the purpose of selling an apartment. The purpose is on one hand to expound the knowledge of the vendor?s decision process and on the other hand to evaluate how the choice of an estate agent is perceived to the vendor. By nine interviews we explored what reasons made vendors choose their agents and whether they were contented with their choice.
