Adaptive Capacity through Complex Adaptive System
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.
An implementation of a rational, reactive agent
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.
Utveckling av minimax-baserad agent för strategispelet Stratego
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.
Val av fastighetsmäklare : En jämförelse småstad/storstad
The number of new estate agent offices is increasing yearly and each year many hundred new estate agents graduate. The comparing of estate agents by sellers has perhaps been most common in larger cities, but as competition has increased even in smaller towns we experience that it has become a common phenomenon even there. We both come from a small town but are not afraid of the idea of moving to a larger city as newly qualified estate agents. We ask ourselves, which are the determining factors in the choice of a estate agent in a large city as opposed to a small town? Can we see any differences? The purpose with this essay is to give us added knowledge about which factors private persons consider to be important in their choice of an estate agent when selling a house.The body of information is based on two parallel surveys, one in Hudiksvall and one in Stockholm, together with interviews of people in this line of business.
Är vi artiga mot virtuella agenter?
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.
Inlärning i Emotional Behavior Networks : Online Unsupervised Reinforcement Learning i kontinuerliga domäner
The largest project at the AICG lab at Linköping University, Cognitive models for virtual characters, focuses on creating an agent architecture for intelligent, virtual characters. The goal is to create an agent that acts naturally and gives a realistic user experience. The purpose of this thesis is to develop and implement an appropriate learning model that fits the existing agent architecture using an agile project methodology. The model developed can be seen as an online unsupervised reinforcement learning model that enhances experiences through reward. The model is based on Maes model where new effects are created depending on whether the agent is fulfilling its goals or not.The model we have developed is based on constant monitoring of the system.
Hur säljare gör sitt val av fastighetsmäklare : en undersökning utförd i Stockholmsområdet
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.
Enkätundersökning om vilka frågor som var viktiga vid valet av fastighetsmäklare
In this report I have compiled my thesis which was about investigating what sellers of real estates find important when they shall appoint a real estate agent. I have also looked into other parameters in my study, like whether the sellers at all use real estate agents and how they have proceeded in case they do not use an agent. In addition to that, I have tried to find out why sellers didn´t chose LRF Konsult and what they know about the company. This analyses was made through questionnaires sent to those estate owners who didn´t use LRF Konsult when they sold their estate. The questionnaires contained 8 questions.
Fastighetsmäklare : varför så dåligt rykte?
Aim: Many people react negatively when they find out that I work as an estate agent. They believe that estate agents earn more money then they should. What many do not know is how hard we must work and that it doesn´t suit someone who is looking for an 8-17 work. As an estate agent I thought it would be interesting to found out why the estate agents have such a bad reputation.Method: This essay is based on the interviews with estate agents and branch organizations but also on newspaper articles about real estate agents. Theory is collected marketing, where I have concentrate on concepts of branding, positioning, communication and image.Result & Conclusions: The factors, which I found in my investigation, that have an effect to the bad reputation are; media, commission, the customers and the bidding.

Utvärdering av den upplevda användbarheten hos CySeMoL och EAAT med hjälp av ramverk för ändamålet och ISO/IEC 25010:2011
This report describes a study aimed at uncovering flaws and finding potential improvements from when the modelling tool EAAT is used in conjunction with the modelling language CySeMoL. The study was performed by developing a framework and applying it on CySeMoL and EAAT in real life context networks.The framework was developed in order to increase the number of flaws uncovered as well as gather potential improvements to both EAAT and CySeMoL. The basis of the framework is a modified version of the Quality in use model from ISO/IEC 25010:2011 standard. Upon the characteristics and sub characteristics of this modified model different values for measuring usability where attached. The purpose of these values is to measure usability from the perspectives of both creating and interpreting models.
Reformation of the credit rating industry - Is there a need?
The credit rating industry is a complex and fascinating industry. Its history stretches back more than 150 years and has gradually increased in importance. During its history the dynamics of the industry have changed. The extended-principal-agent model was developed by synthesizing different principal-agent-relationships into one model. This model provides a holistic understanding of the credit rating industry and illustrates the interdependence between the different relationships.
Design av Riskdatabas : En studie för effektivare hantering av risker
Risk management is a key competency that is constantly being researched how it can be improved within project management. The risk management process consists of four major steps: identify risks, assess the risks? significance on the project, evaluate and address the key risks and follow up.The majority of companies seem to neglect certain identified risks, and decide not to mitigate if the risk does not cause adverse effects to the business. To counteract undesirable consequences and help organisations to become more effective at managing risks an initial work has been conducted for a risk repository.The project develops a proposal on the design of a risk repository which aim to effectively support a database implementation. The study includes literature studies which resulted in a relational model for database implementation.
Kadmium i skånska vattendrag : en metodstudie i föroreningsmodellering
Modelling of pollutants is commonly used in research and at departments working with environmental issues. The need to use large amounts of data when modelling creates the opportunity for more generalised models with lower data demands. Aggregating functions into coarser elements is a sort of generalisation of actual features in nature.A development of a method and a modelling tool called ?KadmiumKalkylatorn? has been performed to model cadmium pollution in rivers in Skåne, Sweden. The water runoff has been multiplied with cadmium standard concentrations based on membership in landuse classes.
GIS-modellering av habitat för vitryggig hackspett (Dendrocopos leucotos) som hjälpmedel i naturvårdsplanering på landskapsnivå :
The white-backed woodpecker is a forest bird being critically endangered in Sweden. The species is dependent on older forests rich in deciduous trees and dead wood. The main problem for the survival of this species is present shortage of habitat. Conservation work on this umbrella species is at present focused on finding remaining or emerging habitat networks. Large areas are scrutinized in search for suitable habitats to be protected or managed for the species sake.
