Author supplied: In a production environment where different products
are being made in parallel, the path planning for every product
can be different. The model proposed in this paper is based
on a production environment where the production machines
are placed in a grid. A software entity, called product agent,
is responsible for the manufacturing of a single product. The
product agent will plan a path along the production machines
needed for that specific product. In this paper, an optimization
is proposed that will reduce the amount of transport between
the production machines. The effect of two factors that influence
the possibilities for reductions is shown in a simulation, using
the proposed optimization scheme. These two factors are the
redundancy of production steps in the grid and the
