Newsvendor solutions with general random yield distributions

Scott E. Grasman, Zaki Sari, Tewfik Sari (2007)

Most systems are characterized by uncertainties that cause throughput to be highly variable, for example, many modern production processes and services are substantially affected by random yields. When yield is random, not only is the usable quantity uncertain, but the random yield reduces usable capacity and throughput in the system. For these reasons, strategies are needed that incorporate random yield. This paper presents the analysis of the newsvendor model with a general random yield distribution,...

Planification des Emplois du Temps et de la Formation au Sein d'une Grande Entreprise

The proposed method not only considers the immediate profitability of the company, but also the training of the collaborators in order to guarantee the success of the company's rising generation. The proposed method uses a greedy approach and constitutes therefore a simple and fast tool for decision makers. It has been successfully implemented in an important Swiss bank society.
