11. Towards a model for managing uncertainty in logistics operations – A simulation modeling perspective
Sammanfattning : Uncertainty rules supply chains. Unexpected changes constantly occur on all levels; strategically through globalization, introduction of novel technology, mergers and acquisitions, volatile markets, and on an operational level through demand fluctuations, and events such as late arrival of in-bound material, machine equipment breakdown, and quality problems.

12. Innovation under pressure : Reclaiming the micro-level exploration space
Sammanfattning : Research & Development (R&D) departments are becoming increasingly structured and routine-based, with tight schedules and daily follow-ups. This way of working stems from increased demands for delivering products to customers quickly and with high quality at a low price. LÄS MER
13. Electricity markets operation planning with risk-averse agents: stochastic decomposition and equilibium
Sammanfattning : The growing penetration of renewable energy sources in electricity systems requires adapting operation models to face the inherent variability and uncertainty of wind or solar generation. In addition, the volatility of fuel prices (such as natural gas) or the uncertainty of the hydraulic natural inflows requires to take into account all these sources of uncertainty within the operation planning of the generation system.

14. Risk factors for esophageal squamous cell carcinoma
Sammanfattning : Aims: The etiology of esophageal squamous cell carcinoma (ESCC) in the high risk areas is largely unknown and a few environmental risk factors which have been identified do not explain its oddly high incidence in esophageal cancer belt. The aims of this thesis were to investigate the association of opium/tobacco consumption, serologic gastric atrophy, gastric mucosa-associated microbiota and contact with farm animals with the risk of ESCC.

15. Capturing the Operational Improvement Potential of Production Systems
Sammanfattning : The operational level is where a company’s manufacturing strategy becomes reality and where customer orders are fulfilled through transforming raw materials into finished goods. The research presented here examines the productivity and capacity of operational processes in manufacturing firms. LÄS MER
