The 18th IASTED International Conference on
Applied Simulation and Modelling
September 7 – 9, 2009
Palma de Mallorca, Spain
Optimization Through Simulation in the Logistic Field
AbstractNew transport and production resources support high flexibility, resulting in a wide range of options in the planning stage. By increasing flexibility, not only are the number of the decision variables and their domain increased, but the system cause-effect time relationships are as well, which complicates the decision-making activities. In fact, flexibility can lead to benefits but can also lead to earliness/tardiness in the distribution operations. The difference between obtaining benefits or losses may depend on the decision-making activity.
Nowadays, due to high competition in the global market, most industries are facing new challenges of capacity and efficiency, where strategic aspects should be considered when automating the tactical decisions, integrating the routing, scheduling and planning decisions together with the logistics aspects. The process of planning the efficient, cost effective flow of products considering not only infrastructure capacity constraints but also costs and delivery quality factors is nowadays considered a complex problem to be solved. New technologies and infrastructure equipment support high flexibility resulting in a wide range of options in the planning stage.
In this talk a modelling approach that supports operational, strategic and tactical decisions by analyzing the cause-effect relationship of any decision represented in a simulation model will be introduced. Numerical examples and applications will be given to illustrate the methods.
Some questions that will be addressed during the talk are:
- Flexibility: when is it needed? How to avoid non-productive operations?
- How to tackle complexity using Simulation Models as DSS to optimize strategic, tactical and operation decisions.
- The use of AI search methods to improve structured knowledge represented in Simulation Models.
