Process flows in service, manufacturing, logistics …
A rewrite of former PFlow.jl based on DiscreteEvents.jl. Please stay tuned.
Processes in service, manufacturing, development, logistics, hospitals ... differ from common stochastic processes as modeled in queueing theory:
Each item (good, customer, job, patient ...) flowing through such systems has its own characteristics or constraints in terms of
- routing: where does it go, in which sequence,
- composition: what other items does its processing need,
- service times: how long does a process step take,
- due times: when has the work to be completed,
- cost: how much does it cost,
- priority: …
Often then there are typical characteristics for different types of SKUs, orders, products ...
Then there are system constraints like
- capacity
- variation
- capability
- reliability
We are interested in throughput, performance, buffer sizes, lead time, cost ...
