Rule Base for Java enabled workflow system -

Rule Base for Java enabled workflow system -

i designing generic scheme should have capability

fetch relevant records database given input. fetch set of rules applicable on given input. filter records based on rules.

i envision scheme maintain rule execution in , not delegate rule engine drools, hence - need inputs on available libraries - allow me store/add/update/manage_conflicts , fetch_relevant rules.

questions : available libraries create rule base of operations , allow fast search on them ?

use case : imagine graph node cities , edges connections. 2 nodes can linked via several edges (train, air, road etc) each having own cost , time constraints. input source node , destination node. rules may : pay octroi charges while in city x, prefer air route between x , y when road , train route not available etc.

ps : workflow fetch info tree graph input (source-destination pair). apply set of rules applicable on each node, each border on path joining source destination.

ps : went through open problems in cs multicommodity demand flow problem on trees/graphs np hard , have similar definitions, scheme trying solve problem sub optimal solution.
