advantage of anyLogistix is the possibility to extend any object using
AnyLogic. This allows you to model site operations inside four walls.

consider a supply chain with Yoghurt Factory in Sarnen which is
supplied by the milk and fruits. Once a week yoghurt bottles are
delivered to customers in Switzerland through two DCs located in Zurich
We assume that in average people consume 50
yoghurt bottles per year. The customers are located in the 50 largest
cities and we assume that the supply chain covers 10% of the total
demand of the cities.
The yoghurt production comprises the following stages:
The goal is to analyze the production process efficiency:
- Solid content normalization: milk mix preparation (97% milk
and 3% milk powder) and graduation (10% volume).
- Deaerating milk.
- Viscolization - blending of two mutually non-soluble
liquids, making them the same throughout.
- Pasteurization - heat treatment.
- Ripening - milk clotting in milk and products of its
processing under the influence of starter microorganisms’ formation.
- Adding Fruit filler. If there is not enough fruits on
factory the process will switch to product utilization.
- Heat treatment.
- Hot product packaging and further cooling.
result shows that the inventory policies for raw materials
replenishment satisfy production needs. However, for continuous
production we must consider the time it takes to deliver the raw
materials to the factory. That is why the produced volume does not
match the production request, but since the customer demand was lower
than the production request, the service level is 100%.
- Estimate the volume of utilized milk mixture.
- Define how often the production was delayed.
- Estimate the service level.
