The single (and multi) item profit maximizing capacitated lot–size (PCLSP) problem with fixed prices and no set–up

Kjetil K. Haugen, Asmund Olstad, Krystsina Bakhrankova, Erik Van Eikenhorst (2010)

Kybernetika

This paper proposes a specialized LP-algorithm for a sub problem arising in simple Profit maximising Lot-sizing. The setting involves a single (and multi) item production system with negligible set-up costs/times and limited production capacity. The producer faces a monopolistic market with given time-varying linear demand curves.

The Speed of Epidemic Waves in a One-Dimensional Lattice of SIR Models

Igor Sazonov, Mark Kelbert, Michael B. Gravenor (2008)

Mathematical Modelling of Natural Phenomena

A one-dimensional lattice of SIR (susceptible/infected/removed) epidemic centres is considered numerically and analytically. The limiting solutions describing the behaviour of the standard SIR model with a small number of initially infected individuals are derived, and expressions found for the duration of an outbreak. We study a model for a weakly mixed population distributed between the interacting centres. The centres are modelled as SIR nodes with interaction between sites determined by a diffusion-type...
