In this work we consider an industrial maintenance process control problem using cellular automata approach. The problem consists on finding an optimal control for the assignment and the displacement of agents in a spatial area to maintain the equipments in good working state. The approach by cellular automata is based on: an operating statistics for determining the attributes of equipments and...

Individuals base decisions on their surroundings and change their minds based on the action of others and interactions with the environment. Current Cellular Automata techniques for modeling pedestrian movement predetermine the individual’s goals and do not change them throughout the execution of the simulation. To allow the individuals to make decisions as the simulation progresses a technique...

The most important interactions between cellular molecules have a high affinity, are unique and specific, and require a network approach for a detailed description. After a brief introduction to cellular networks (protein--protein interaction networks, metabolic networks, gene regulatory networks, signalling networks and membrane--organelle networks) an overview is given on the network aspects ...
