APL models for operational planning of shipment routing, loading, and scheduling

摘要

A vehicle routing algorithm with an imbedded loading heuristic and movement simulation was developed to provide the interactive capability to plan shipment delivery and returns.

The vehicle movement model is a small discrete event fixed interval simulation that uses the APL operators to keep track of loading facility status, truck location, etc. for scheduling purposes.

The models operate in a field environment, but are linked to centralized planning models and data bases.

They are illustrative of APL's almost unique ability to combine simulation modeling with operational restrictions such as interactive operation by non-programmers.
