Process model analysis of parenchyma sparing laparoscopic liver surgery to recognize surgical steps and predict impact of new technologies

Background: Surgical process model (SPM) analysis is a great means to predict the surgical steps in a procedure as well as to predict the potential impact of new technologies. Especially in complicated and high-volume treatments, such as parenchyma sparing laparoscopic liver resection (LLR), profound process knowledge is essential for...

Strategies to Regulate Inbound Logistics at Convention Centers: A Case Study at the RAI Amsterdam

Convention centers are facing logistic challenges due to poor performance, lack of space and governmental regulations. This research is focused on finding strategies that can improve performance while maintaining or reducing space and complying to these governmental regulations. In this research three main strategies are introduced that can...

A discrete event simulation procedure for validating programs of requirements: The case of hospital space planning

This paper introduces a Discrete-Event Simulation (DES) tool developed as a parametric CAD program for validating a program of requirements (PoR) for hospital space planning. The DES model simulates the procedures of processing of patients treated by doctors, calculating patient throughput and patient waiting times, based on the number of...

Optimal Configuration of an Automated Dairy Factory

Currently a new small and automated dairy factory for the onsite production of cheese at farms is under devel-opment. This new factory aims at the production of cheese without any human interaction, based on the (raw) milk from cows who are milked with a milking robot. At the moment only a small test factory exists, in which human interaction is...

Evaluating performance improvement strategies in a closed-loop supply chain: A case study at KLM E&M Component Services

KLM Engineering & Maintenance Component Services manages a spare part pool. They are responsible for ensuring spare part availability for their contracted customers. For rotable spare parts, which are interchangeable and repairable, the supply chain is closed-loop. As the demand for spare parts is sporadic, with large zero demand periods, a...

Simulating the construction of conceptual space architecture to explore the potential of combined asteroid mining and space-based 3d manufacturing

Space-based manufacturing is considered a crucial next step for the further development of human settlement in space. There are vast quantities of building resources distributed throughout space, with asteroids among the most apparent candidates for large-scale mining and resource provision. In this presentation, we present a hybrid...

Data assimilation in the minerals industry: Real-time updating of spatial models using online production data

Declining ore grades, extraction at greater depths and longer hauling distances put pressure on maturing mines. Not enough new mines will be commissioned on time to compensate for the resulting shortages. Ore-body replacement rates are relatively low due to a reduced appetite for exploration. Development times are generally increasing and most...
