1. 1. The Application of Multivariate Statistical Process Control during Industrial Hot Isostatic Pressing Sintering Processes : A Case study at Seco Tools AB

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

   Författare :Karl Ericsson; [2023]
   Nyckelord :Multivariate statistical process control; Batch processes; Quality prediction;

   Sammanfattning : This Master's thesis focuses on improving the understanding and monitoring of the Hot Isostatic Pressing (HIP) sintering process used by Seco Tools AB to manufacture cemented carbides for cutting tools. While essential for producing cutting tools with superior hardness and toughness the HIP sintering process introduces a complex relationship between the selected process parameters and the achieved materials properties.

   Sammanfattning : Date: 1st of June, 2022 Level: Master thesis in Business Administration, 15 cr Institution: School of Business, Society and Engineering, Mälardalen University Authors: Orkhan Aslanov (1998/01/12) Muhammad Faisal Bin Zainal Fitri (1995/09/26) Title: Hidden costs in the managerial practices of remote working and digital transformation in Ericsson Supervisor: Edward Gillmore Keywords: Digital transformation, Remote working, Competences, Managerial practices, Pandemic Research question: What are the hidden costs in the implementation of digital tools for remote working and what kind of competences have managers developed to overcome challenges? Purpose: The purpose of this paper is to expand the horizons of what is currently understood within remote working regarding managerial practices in organizations by analyzing the emerging hidden costs of digital implementation for remote working in a Nordic-based organization as well to contribute to the limited existing research within this area. Method: The study follows qualitative analysis and the data was collected by conducting seven semi-structured online interviews with managers working at Ericsson's headquarters office in Stockholm.
