<p>This thesis develops a method for examining a logistics system and evaluating its performance so that problem areas can be identified. This method is developed based on a literature review and evaluated through workshops and case studies. It consists of four steps; System Description, Input and Output, Transformation and finally Deeper Analysis and Conclusions. By conducting an evaluation based on the method conclusions can be drawn concerning the logistics performance of the system within a week.</p>

Studies in newsvendor decision-making have shown that human decisions systematically deviate from analytical solutions found in many utility models of the single period problem (SPP). Yet for the most part the impacts of this human decision bias in systems of newsvendor type products have not been investigated. We study bias in human decision-making to determine how different factors affect the performance of systems of newsvendor type products. We extended the state of the arts utility models of SPP to analyze the effects of individuals wealth on individual decision-making. Our theoretical and empirical results proved that individuals wealth significantly affected individual decision-making. Specifically, our analysis concluded that wealthier individual ordered more than poorer individual did when presented with the same investment opportunity. We created a human decision bias (HDB) model to include different newsvendor ordering policies that individuals could use to determine their order quantities. This model is set up to investigate individuals reliance on different ordering policies under different experimental conditions. We designed multi period newsvendor experiments to study effects of factors such as item profit margin, wealth, value of learning, and salvage value on decision-maker's order quantity. We found that wealth and profit margin factors significantly affected individual newsvendor decision-making. Learning, gender, and salvage value factor did not exhibit significant effects in our empirical studies. We designed multi period multi echelon newsvendor experiments to study effects of factors such as the relationship between newsvendors, item profit margin, and newsvendors' wealth on the performance of two-echelon newsvendors system. We found item profit margin, wealth, and relationship between supplier and retailer to significantly affect newsvendor decision-making. Finally, we present a case study of US fresh produce industry to illustrate the impacts of human decision bias on the performance of a supply chain system.

Für die ergonomische Bewertung der auf die Mitarbeiter im Gewerk Logistik einwirkenden Belastungen ist eine valide Systematik anzuwenden. In ersten Untersuchungen konnte gezeigt werden, dass für typische in der Logistik auftretende Belastungen keine geeignete Systematik verfügbar ist, die sämtliche Belastungsfaktoren bewerten kann. Dazu wurde ausgehend von einer Analyse der identifizierten Belastungen anhand von drei ausgewählten Verfahren versucht, diese zu bewerten. Die dabei identifizierten Defizite bilden die Grundlage für eine Entwicklung eines Verfahrens zur vollständigen Bewertung der Belastungen in logistischen Prozessen.
