Hierarchical planning in a single stage system

Single stage systems with high set-up times and high utilization levels occur in flow process industries. In this paper a two-tiered hierarchical model is developed for such a system. At the top level, the optimal value of the control parameters is determined, while the operational scheduling function is performed at the bottom level. The conceptual aggregation approach used in this model is compared to the aggregation approach used in classical hierarchical approaches

Pulse Producer Decision Making Under Risky Conditions: Will End-Point Royalties Change Preferences?

In 2015, the Agriculture for Growth Act (C-18) came into effect in Canada. This Act modernized plant breeding by including amendments that aligned it with the 1991 International Convention for the Protection of New Plant Varieties (UPOV91) (CFIA, 2017). Regulations within the Act grant plant breeders the right to charge an end-point royalty (EPR) on harvested grain. This thesis is interested in assessing how provenance and framing, influence pulse producer seed choice decisions. This study created a prospect theory behavioral experiment to answer this question. The study concluded that producers are not overly influenced by provenance and framing and instead make decisions based on the expected utility model, except when questions are manipulated by both EPR and negative framing. The study also concluded that most producers (56%) are willing to tolerate a level of risk. This provided a way to profile producers by risk tolerance and found many similarities and few minor differences between those that are always risk-seeking, always risk-averse, and occasionally risk-seeking

Order release strategies to control outsourced operations in a supply chain

In this paper, we propose and compare three different order release strategies to plan and control outsourced operations in a supply chian where the contract manfacturer is producing different variants of a certain product

Strategic and operational outsourcing : decisions in the pharmaceutical industry

In this paper, we develop a framework of outsoucing research by providing a distictive view on the (recent) outsourcing literature

Ocean container transport : an underestimated and critical link in global supply chain performance

With supply chains distributed across global markets, ocean container transport now is a critical element of any such supply chain. We identify key characteristics of ocean container transport from a supply chain perspective. We find that unlike continental (road) transport, service offerings tend to be consolidated in few service providers, and a strong focus exists on maximization of capital intensive resources. Based on the characteristics of the ocean container transport supply chain, we list a number of highly relevant and challenging research areas and associated questions
