Reinsurance is one of the tools that an insurer can use to mitigate the underwriting risk and then to control its solvency. In this paper, we focus on the proportional reinsurance arrangements and we examine several optimization and decision problems of the insurer with respect to the...

Bedingt durch den ständig zunehmenden Kostendruck wird es für Unternehmen immer wichtiger, Kostensenkungspotenziale systematisch zu identifizieren. Eine von vielen Unternehmen genutzte strategische Option ist die internationale Arbeitsteilung. Kostenvorteile entstehen hier vor allem durch...

This paper studied the impact of multiple, unrelated decisions on behavior in a newsvendor setting. We experimentally study and compare the performance of newsvendors who make two simultaneous newsvendor decisions versus one decision, and find some evidence that individuals who make two...

The PROMETHEE is a significant method for evaluating alternatives with respect to criteria in multi-criteria decision-making problems. It is characterized by many types of preference functions that are used for assigning the differences between alternatives in judgements. This paper proposes a...

Supplier risks have attracted significant attention in the supply chain risk management literature. In this article, we propose a new computational system based on the "Fuzzy Extended Analytic Hierarchy Process (FEAHP)" method for supplier selection while considering the relevant risks. We...

Many theoretical models adopt a normative approach and assume that decision-makers are perfect optimizers. In contrast, this paper takes a descriptive approach and proposes a decision framework of bounded rationality, in which decision-makers are prone to errors and biases. In our model, while...

We consider a dual channel supply chain in which a manufacturer sells a single product to end-users through both a traditional retail channel and a manufacturer-owned direct online channel. We adopt a commonly used linear demand substitution model in which the mean demand in each channel is a...
