We consider in this paper a two echelon timber procurement system in which the first echelon consists of multiple harvesting blocks and the second echelon consists of multiple mills (e.g., sawmills), both distributed geographically. Demand is put forward by mills in the form of volumes of logs of specific length and species. Due to the impact of log handling and sorting on cut-to-length harvest...

Introduction: Planning of bolus chase MR angiography (MRA) can be considerably optimized by the application of a vessel scout [1]. Recently, the concept of a time-offlight (TOF) non contrast enhanced (CE) vessel scout was presented which is based on the continuously moving table (CMT) acquisition of projection data [2]. This study presents advanced acquisition and data processing strategies for...

Introduction A persistent problem of the generation of 3D tissues for therapeutic application is efficient nutrient supply and removal of waste products within complex constructs. Depending on the tissue to be reverse engineered, a more or less intense supply of substrates and oxygen must be provided, as diffusion processes are limiting as tissue thickness increases. Thus, the use of decellular...

The supply chain is a system comprising organizations, decision makers, and technology decision policies that is responsible for transforming raw materials into finished products that are delivered to end customers. As expanded upon later in the paper, the supply chain is traditionally characterized by counter-current flows of information and material. Material flows from the raw material suppl...

As today’s supply chain (SC) networks are globalized complex systems planning and optimizing SC processes is harder than ever. Unexpected deviations and disruptions can lead to devastating and far-reaching consequences. Hence, the management of SC risk (SCR) is of fundamental importance. The literature on SCR is, however, mostly of anecdotic nature; only few authors present empirical research. ...

Amixed integer stochastic programming model is established to support strategic planning of bioenergy supply chain systems and optimal feedstock resource allocation in an uncertain decision environment. The two-stage stochastic programming model, together with a Lagrange relaxation based decomposition solution algorithm, was implemented in a realworld case study in California to explore the pot...

Describes a case study of supply chain collaboration facilitated by a decision support environment in a high-tech electronics supply chain with multiple independent companies. In a business process called collaborative planning, representatives from these companies jointly take decisions regarding production and shipments for a large part of their collective supply chain. Particular attention i...

Preoperative embolization of meningiomas can be safely performed using a variety of embolic agents. Most commonly, the vascular supply from branches of the external carotid artery is the target of embolization. In our report, we detail the treatment of a patient with a parafalcine meningioma that received its supply via branches of the anterior cerebral artery. One of the feeder vessels appeare...

For manufacturing industries, the integration of business processes from customer-order management to delivery (Supply Chain Management) has widely been received much attention from the viewpoints of agile and lean manufacturing. Supply chain planning concerns broad activities ranging network-wide inventory management, forecasting, transportation, distribution planning, production planning and ...
