TL;DR: In this article, a discrete event simulation is used to examine how a manufacturer can combine traditional order data available from non-VMI customers with sales data from VMI customers in its production and inventory control and what impact this has on the manufacturer's operational efficiency.

TL;DR: In this article, the authors present a framework for supply chain decision-making, which is used to gain insights into applications of model-based decision making in the product development phase.

TL;DR: In this paper, the authors put discrete event simulation in place in the project implementation process by suggesting that it can help to introduce new insights to conventional project scope management practices, and four simulation cases are presented to illustrate empirically how the management focus is casted in a strategic way to the functionality and operability of the project product.

TL;DR: A practical scheduling system that considers the advantages of both surgery categorization and newsvendor model to surgery scheduling is developed and a remarkable decrease in scheduling inefficiency is found.

TL;DR: The main factors influencing operation length were type of operation, redoing the operation and the head surgeon, and reduction of changeover time between surgeries by inducing anaesthesia outside an operating theatre and by reducing slack time at the end of day after a second surgery have the strongest effects on surgery output and productivity.
