Abstract
The paper describes a Multimodal Transportation Network (MTN) in which several unimodal networks (Automated Guided Vehicles (AGVs), hoists, lifts, etc.) interact with each other via common shared workstations to provide a variety of demand-responsive material handling operations. Different material handling transport modes provide movement of work pieces between workstations along their manufacturing routes in the MTN. In this context the multimodal processes standing behind multiproduct production flow while executed in MTN can be seen as processes realized with synergic utilization of various local periodically acting processes. Such processes play a determining role in the evaluation of functioning efficiency inter alia in public transport systems, goods transport, energy and data transmission etc. The solution to a constraint satisfaction problem aimed at AGVs fleet match-up scheduling subject to fuzzy operation times constraints is our main contribution. In the considered case both production rate (production takt) and operations execution time are described by imprecise (fuzzy) data.
