Total span of farm work flow using Petri net with resource sharing

摘要

The aim of this work is to present the graphical model of farm work flow (FWF) problem with multi resources sharing, in which each operation may need more than one kind of resources. Using the Petri net concept with resource shared places we describe the farming process mathematically and graphically, and simulate the farming activation and resources assignment. The marking that is one of the properties of Petri nets facilitates mastering the farming progress and the status of the farmland and resources. Here, we apply a new concept deadlock-free Petri net model with resource sharing for minimising the total span of FWF, which is essential in agricultural production systems.
