Det här examensarbetet har utförts på Scania CV AB:s motorbearbetningsavdelning i Södertälje. I dagsläget pågår en omställning av tillverkningsprocessen på avdelningen där två nya tillverkningslinor, en för cylinderblock och en för cylinderhuvud, är under uppbyggnad. Linorna kommer styras med hjälp av ett Manufacturing Execution System. Ett Manufacturing Execution System har i uppgift att samla in data och information från tillverkningsprocessen, som sedan kan presenteras i ett gränssnitt. Vilken information som kommer finnas tillgänglig att presentera i systemet styrs utifrån en intern kravspecifikation som ska spegla International Society of Automation:s standard, även känd som ISA-95. Den kravspecifikation som finns för systemet är framtagen av IT-avdelningen i samråd med avdelningschefer. För närvarande är det osäkert om kravspecifikationen som finns på systemet stämmer överens med vad medarbetarna behöver för att kunna arbeta på ett effektivt sätt. Det här arbetet kartlägger behovet hos medarbetarna och jämför det med den befintliga kravspecifikationen. Genom intervjuer och enkäter har den befintliga kravspecifikationen för systemet jämförts med vad medarbetarna anser vara önskvärda funktioner i systemet. Resultatet av den första omgången intervjuer och enkätutskick var att kravspecifikationen och behovet hos medarbetarna stämmer väl överens. Det mynnade ut i att ytterligare en enkät skickades ut där medarbetarna istället skulle rangordna den information som kommer finnas tillgänglig i systemet utefter en prioriteringsskala i tre nivåer. Resultatet från den enkäten gav en bild av vilken information medarbetarna tycker är viktigast för att kunna arbeta på ett effektivt sätt. / This bachelor thesis has been done at Scania CV AB’s department for engine manufacturing in Södertälje. The manufacturing process at the department is currently under development, where two new lines are being added, one for cylinder head and one for cylinder blocks. These two new manufacturing lines are going to be controlled with the help of a Manufacturing Execution System. The Manufacturing Execution Systems task is to collect data and information from the manufacturing process, which later can be presented in an interface. There is a specification at Scania that presents what information will be available in the system. That specification is in line with what the International Society of Automation has specified in ISA-95. The specification for the system was set by the IT-department in consultation with department managers. There is currently an uncertainty if the specification meets the requirement that the workers has, to be able to work efficiently with the system. This thesis will identify the requirement that the workers has on the system, and compare it with the current specification. What the workers deems is necessary information has been identified and mapped through interviews and a survey. The result of these interviews and the survey made it clear that the specification was well in line with the requirement from the workers. This information led to the decision to send out another survey that asked the workers to prioritize how important the information in the system is, in three different priority levels. This resulted in an overview of what the workers consider is the most important information in the system.

The goal of my master‘s thesis is to create a digital twin of a testbed Barman. The Barman is a school model of autonomous mixed drinks production line that demonstrates the principles of Industry 4.0. In the theoretical part of the thesis, the choice of a suitable tool for virtualization is discussed. The Tecnomatix Process Simulate and the Mechatronic Concept Designer module integrated in the NX platform is compared. The practical part of the work is divided into two phases. The first phase was about looking for a way to integrate the robotic SCARA manipulator. The second phase was focused on the virtualization of the cell Shaker in the latter of the tools mentioned before. This work is designed as a guide for creating and verifying the concept of a digital twin.

Lean production determine the appropriate way to better workplace organization based on the elimination of various types of wasting, which only increase costs without adding customer value. It isn't important only implementation of lean production methods, but especially maintenance of lean principles and creating an atmosphere of continuous improvement. Lean production is the philosophy, which must be accepted by all em-ployees inside every company. It is the way to successful business in the 21st century. This thesis deals with the application of lean production in the selected company. The practical part describes the selected company, its history and manufacturing program. The next part is focused on description of the production center and its production layout. The result of this thesis is creating the product layout plan depending on the material flow and additional proposals for improvement.

This master’s thesis named Continuous/batch production in environment Industry 4.0 deals with software and principles that are designed for discrete manufacturing and their application to the continuous and batch production. First, the functions and properties of individual programs for discrete manufacturing were descripted, then this acquired knowledge was related to continuous and batch production. On the basis of the gained knowledge, a program for the processing of liquid materials with using two tanks was created. This program is aimed at customizing of the final product.

The logistics industry is one of the most important industries, being an important component of a company's activities. In recent years, the industry has gone through a large number of changes. These had the purpose of making the processes more efficient in order to reduce costs or to increase the degree of competitiveness. A very important process in the logistics industry is the allocation of roles in warehouses. Not using the available resources to their maximum capacity leads to an increase in the processing time of the units as well as to a decrease in the profitability of the companies. Allocation is done manually in the warehouse, being a complex task in which many constraints and variations must be taken into account. AI technologies and IoT systems have the potential to simplify the process of assigning workers. For this research, a warehouse in Germany operated by the Amazon company was studied. In addition to the benefits that this transition can have from a social point of view, helping to equalize the roles of high complexity and the appropriate rotation of jobs to ensure equal opportunities for development, there is an opportunity to reduce the costs associated with this process by up to 90%. This last aspect is dependent on the degree of modernization of the warehouse and on the way in which the role allocation process is carried out at the time. Most of the IoT systems necessary for the digitization and automation of this process are already implemented in warehouses. However, a common architecture is needed to be able to guarantee the integration and compatibility of the systems. The main blocker in this transition remains public opinion and financial factors, companies with a large volume of units potentially benefiting from economies of scale. / Logistikbranschen är en av de viktigaste branscherna och är en viktig del av ett företags verksamhet. De senaste åren har branschen genomgått ett stort antal förändringar. Dessa hade till syfte att effektivisera processerna för att minska kostnaderna eller öka graden av konkurrenskraft. En mycket viktig process inom logistikbranschen är fördelningen av roller i lager. Att inte använda de tillgängliga resurserna till sin maximala kapacitet leder till en ökad handläggningstid för enheterna samt till en minskad lönsamhet för företagen. Allokering sker manuellt i lagret, vilket är en komplex uppgift där många begränsningar och variationer måste beaktas. AI-teknik och IoT-system har potential att förenkla processen för att tilldela arbetare. För denna forskning studerades ett lager i Tyskland som drivs av Amazon-företaget. Förutom de fördelar som denna övergång kan ha ur en social synvinkel, hjälpa till att utjämna rollerna med hög komplexitet och lämplig rotation av jobb för att säkerställa lika möjligheter till utveckling, finns det en möjlighet att minska kostnaderna förknippade med denna process med upp till 90 %. Den sista aspekten är beroende av graden av modernisering av lagret och på det sätt på vilket rollfördelning processen går till vid tillfället. De flesta av de IoT-system som krävs för digitalisering och automatisering av denna process är redan implementerade i lager. Det behövs dock en gemensam arkitektur för att kunna garantera systemets integration och kompatibilitet. Den huvudsakliga blockeraren i denna övergång är fortfarande den allmänna opinionen och finansiella faktorer, företag med en stor volym av enheter som potentiellt kan dra nytta av stordriftsfördelar.
