1. Dynamic Modelling and Analysis of Information Flows in Production-Inventory and Supply Chain Systems
Sammanfattning : System dynamics is the fundamental concept of this academic dissertation. The focus is on analysis and modelling of properties representative for production-inventory and supply chain systems. The modelling approach is based on Industrial Dynamics but employs a hybrid approach of Control Theory and simulation in the analysis. LÄS MER
2. A study on emerging electronics for systems accepting soft errors
Sammanfattning : Moore’s law has until today mostly relied on shrinkage of the size of the devices inintegrated circuits. However, soon the granularity of the atoms will set a limit together with increased error probability of the devices. How can Moore’s law continue in thefuture? To overcome the increased error rate, we need to introduce redundancy. LÄS MER
3. A Method for Customer-driven Purchasing : Aligning Supplier interaction and Customer-driven manufacturing
Sammanfattning : The role of a purchaser has traditionally focused on acquiring standard items at the lowest possible cost. The ability to reduce unit cost has been the key performance indicator for purchasers. Most traditional purchasing strategies thus focus on optimizing this situation, focusing on the supplier interface only and not on customer value. LÄS MER
4. Reducing and absorbing variations in a manufacturing context : A capacity management perspective
Sammanfattning : Variations can have substantially negative effects on performance and it is therefore important to investigate how the variations can be reduced or absorbed in an appropriate way for competitiveness. Manufacturing companies are daily exposed to variations and operations managers need to take capacity management decisions with this in mind to secure the delivery capability. LÄS MER
5. Supply chain coordination using optimal transfer pricing to balance co- and byproduct demand within a process industry
Sammanfattning : Process industries has for long been important for the development of Swedish industry and society. All industries face different conditions that affect how to best run their operations. This thesis aims to describe some of the conditions that characterize process industries compared to other industries. LÄS MER
