To maintain production in high salaries countries and strength in competition against other companies, it is today more important than ever to maximize production, offer a wide spectra of products and be able to deliver on the customers desire of shorter and shorter delivery time. Flexible production and short time spent on die changes is vital to achieve these desires. The interest for die changeover time reduction grew in the same pace as the demand for increased product variety grew. SMED as a method of reducing time spent on die changeovers were developed in between 1950-1970, by the Japanese Shigeo Shingo.The purpose of this thesis work has been to investigate the result of SMED in a die casting facility, and compare the result from it with the result considering time spent on die changeovers when investing in new equipment. The goal is to implement a thorough investigation by using the SMED method at Tenhults Pressgjuteri AB and make a brochure that have to be simple to understand, in purpose to draw interest to the advantages of using SMED as a method.Commissioned by the Swedish foundry association Swecast, the work has been carried out by studying die changeovers at Tenhults Pressgjuteri AB, where filming and interviews with the operators have been included in the analysis.

This thesis investigates lacks in today?s use of the ERP-system Mapaz Affärssystem inthe production planning at Solna Pressgjuteri, and possible improvements. Today thedates calculated by the program to plan the orders are inaccurate and the ordersequence is not optimal, and therefore continuous manual corrections are needed.The approach was to study the program Mapaz to understand how it works, andidentify available parameters for input and output in the different tools offered in theprogram. By studying old lists of planned orders and relevant parameters in Mapaz forindividual orders, production groups, products and operations, the connectionbetween input and output parameters could be understood.Participating in planning meetings and discussions with the company behind theERP-system identified the current usage, desideratum and possibilities with theavailable tools. These were then matched to describe the reasons to the insufficientplanning and form possible actions for improvement.The work has showed poor understanding for the ERP-system and its functions, assome tools intended to assist the planning were not used, and some even usedincorrectly.

Arbetet redovisar ett projektarbete som utförts på AB Lundbergs Pressgjuteri i Vrigstad där planhetsavvikelser av en specifik detalj har analyserats. Analyserna har tagit hänsyn till både yttre och inre faktorer i gjuteriprocessen och resultat visar att kylningen av detaljen har en betydande inverkan på detaljens planhet..

This exam paper has been a collaboration between the writers and SYSteam Utvecklingspartner in Huskvarna. The assignment was about finding a need for a mobile application, making a requirement specification document with design documents and parallel to this constructing a prototype. The assignment is summarized in the following questions:? How can companies in the forest industry benefit from mobile information technology?? How can a user centered perspective be used in the process of making the requirement specification document and the design documents?? How do guidelines for usability apply to a mobile application?Three visits to companies in the forest industry were made to find a need for mobile information technology solutions. After a small analysis of the different companies? problems and conditions the decision was to use Tenhults Impregneringsverk AB in the case study.We used the FA/SIM method in our job of finding the organization needs for change and the principles of User Centered Design in the work of constructing a prototype.The result of our work is a requirement specification with design documents and a prototype.
