    We propose a mixed-integer program for planning the production and distribution of products for a medium-sized bakery company consisting of a single production location and several shops where products are sold. The production planning is based on the general lot sizing and scheduling (GLSP) model and the distribution part is modeled as an inventory routing problem (IRP). We consider the product freshness and the production and distribution costs explicitly in a multi-objective framework. Due to the complexity of the model we solve the problem approximately. The computed approximation of the Pareto front indicates that a considerable improvement of the freshness of products can be achieved with only a small increase of the cost.
