Article
In this paper we analyze heterogeneity and asymmetry of ordering behavior in high-profit and low-profit product settings as well as applicability of the reference dependent newsvendor model with different psychological costs of overordering and underordering. Further, we introduce a mean preserving newsvendor model by extending the overconfident ne...

There are numerous applications of game theory in the analysis of supply chains where multiple actors interact with each other in order to reach their own objectives. In this paper we review the use of non-cooperative game theory in inventory management within the newsvendor framework describing a single period inventory control model with the focu...

We consider two firms which pool some of their inventory. The pool is created by the firms' contributions, and a firm's entitlement for an allocation from the pool (if needed) is a function of its contribution. Transshipment from the pool is costly, but the firms can benefit from reduced risk through inventory sharing using the pool. We analyze the...

Critical raw materials like rare-earth elements are essential inputs for the production process of many electronic products, but also for environmentally-friendly green-energy technology products. The market for these materials faces high uncertainty associated with their supply. The use of recovered raw materials can help to mitigate the risk and...

In this paper we investigate a manufacturer’s sustainable sourcing strategy that includes recycled materials. To produce a short life-cycle electronic good, strategic raw materials can be bought from virgin material suppliers in advance of the season and via emergency shipments, as well as from a recycler. Hence, we take into account virgin and rec...

We study risk pooling via unidirectional lateral transshipments between two locations under local decision-making. Unidirectional transshipments can be applicable when cost structures and/or capabilities differ between locations, and it is also a common practice in dual channel supply chains with online and offline sales channels. We show that such...
Article
Pooling is a best practice in inventory management for economic objectives. In this paper we investigate whether pooling stays advantageous if environmental sustainability is considered in addition to the economic performance, i.e. we analyze whether pooling could have a negative impact on the environment and evaluate the resulting trade-off betwee...
Article
Cooperation among humanitarian organizations has attracted increasing attention to enhance effectiveness and efficiency of relief supply chains. Our research focuses on horizontal cooperation in inventory management which is currently implemented in the United Nations Humanitarian Response Depot (UNHRD) network. The present work follows a two-step...
Article
We present a mixed integer linear programming (MILP) approach for an aggregate production planning (APP) problem of an electronics manufacturer. A multi-item, multi-facility, multi-stage capacity planning problem over a finite planning horizon with deterministic demand is considered. We include the flexibility instruments shift planning, overtime a...
Article
As suppliers are crucial for successful supply chain management, buying companies have to deal with the risks of supply disruptions due to e.g. labor strikes, natural disasters, supplier bankruptcy, and business failures. Dual sourcing is one potential countermeasure, however, when applying it one loses the full potential of economies of scale. To...
Article
Interruptions in supply can have a severe impact on company performance. Their mitigation and management is therefore an important task. Reasons for interruptions can be machine breakdowns, material shortages, natural disasters, and labour strikes. Sourcing from multiple suppliers is a strategy to deal with and reduce supply disruption risk. We stu...
