Companies operating in the wood processing industry need to increase their productivity by implementing automation technologies in their production systems. An increasing global competition and rising raw material prizes challenge their competitiveness. Yet, too extensive automation brings risks such as a deterioration in situation awareness and operator deskilling. The concept of Levels of Automation is generally seen as means to achieve a balanced task allocation between the operatorsâ skills and competences and the need for automation technology relieving the humans from repetitive or hazardous work activities. The aim of this thesis was to examine to what extent existing methods for assessing Levels of Automation in production processes are applicable in the wood processing industry when focusing on an improved competitiveness of production systems. This was done by answering the following research questions (RQ): RQ1: What method is most appropriate to be applied with measuring Levels of Automation in the wood processing industry? RQ2: How can the measurement of Levels of Automation contribute to an improved competitiveness of the wood processing industryâs production processes? Literature reviews were used to identify the main characteristics of the wood processing industry affecting its automation potential and appropriate assessment methods for Levels of Automation in order to answer RQ1. When selecting the most suitable method, factors like the relevance to the target industry, application complexity or operational level the method is penetrating were important. The DYNAMO++ method, which covers both a rather quantitative technical-physical and a more qualitative social-cognitive dimension, was seen as most appropriate when taking into account these factors. To answer RQ 2, a case study was undertaken at a major Swedish manufacturer of interior wood products to point out paths how the measurement of Levels of Automation contributes to an improved competitiveness of the wood processing industry. The focus was on the task level on shop floor and concrete improvement suggestions were elaborated after applying the measurement method for Levels of Automation. Main aspects considered for generalization were enhancements regarding ergonomics in process design and cognitive support tools for shop-floor personnel through task standardization. Furthermore, difficulties regarding the automation of grading and sorting processes due to the heterogeneous material properties of wood argue for a suitable arrangement of human intervention options in terms of work task allocation.  The application of a modified version of DYNAMO++ reveals its pros and cons during a case study which covers a high operator involvement in the improvement process and the distinct predisposition of DYNAMO++ to be applied in an assembly system.

I takt med att digitala medier har utvecklats under de senaste Ã¥ren har kÃpresan fÃr-ändrats till att kunder idag i ett mycket senare skede släpper in leverantÃrer i dialogen. Marketing Automation adresserar den problembilden och har växt fram som en brygga mellan sälj- och marknadsprocessen. Systemet ger mÃjlighet att effektivt och automatiserat utveckla leads (potentiell kund). Syftet med denna studie är att undersÃka hur Marketing Automation pÃ¥verkar sälj- och marknadsprocesserna. Vilka fÃrutsättningar krävs fÃr en implementation? Ãkar lÃnsamheten? Vi har därfÃr valt att i det teoretiska ramverket beskriva Marketing Automation och bland annat undersÃka om ett infÃrande av Marketing Automation medfÃr att sälj- och marknadsorganisationerna slÃ¥s samman till en organisatorisk enhet. I studien har vi dessutom kartlagt och beskrivit den moderna kÃpresan och det som ibland kallas intäktsorganisationen. Vi har funnit att Marketing Automation är relativt outforskat i en svensk kontext. FÃr att utrÃna om teorin, som i stor utsträckning bygger pÃ¥ internationell litteratur och internationella undersÃkningar, gÃ¥r att ÃverfÃra till en svensk kontext har vi valt att genomfÃra en kvalitativ studie i form av en fallstudie av leverantÃrer av produkter och tjänster inom omrÃ¥det samt fÃretag, med den gemensamma nämnaren att de re-presenterar ett kunskapsintensivt erbjudande och har implementerat lÃsningar fÃr Marketing Automation. I vÃ¥r analys finns en samsyn mellan leverantÃrer och kunder i fÃrutsättningar fÃr ett infÃrande, men vi kan även se hur resultaten divergerar och pekar pÃ¥ implikationer, inte minst avseende mÃ¥luppfyllnad och samverkan mellan sälj- och marknadsorgani-sationerna. VÃ¥r slutsats visar bland annat att Marketing Automation kan leda till uppfyllnad av mjuka värden i fÃretaget men har inte bevisats leda till Ãkad lÃnsamhet per automatik. Vi ser lÃnsamhet och Return on Investment (ROI) som ett omrÃ¥de som bÃr utforskas vidare.

Networked control over data networks has received increasing attention in recent years. Among many problems in networked control systems (NCSs) is the need to reduce control latency and jitter and to deal with packet dropouts. This paper introduces our recent progress on a queuing communication architecture for real-time NCS applications, and simple strategies for dealing with packet dropouts. Case studies for a middle-scale process or multiple small-scale processes are presented for TCP/IP based real-time NCSs. Variations of network architecture design are modelled, simulated, and analysed for evaluation of control latency and jitter performance. It is shown that a simple bandwidth upgrade or adding hierarchy does not necessarily bring benefits for performance improvement of control latency and jitter. A co-design of network and control is necessary to maximise the real-time control performance of NCSs

This paper presents the Smarty Board; a new micro-controller board designed specifically for the robotics teaching needs of Australian schools. The primary motivation for this work was the lack of commercially available and cheap controller boards that would have all their components including interfaces on a single board. Having a single board simplifies the construction of programmable robots that can be used as platforms for teaching and learning robotics. Reducing the cost of the board as much as possible was one of the main design objectives. The target user groups for this device are the secondary and tertiary students, and hobbyists. Previous studies have shown that equipment cost is one of the major obstacles for teaching robotics in Australia. The new controller board was demonstrated at high-school seminars. In these demonstrations the new controller board was used for controlling two robots that we built. These robots are available as kits. Given the strong demand from high-school teachers, new kits will be developed for the next robotic Olympiad to be held in Australia in 2006.
