Loads-N-Limits and Release-N-Sequence: The "Brains" Behind WEPS

Abstract

The Loads-n-Limits (LNL) and Release-n-Sequence (RNS) modules are rule-based sub-systems designed to validate vari-ous configurations of aircraft stores loading and weapons re-lease planning. LNL, in conjunction with verifying and vali-dating the loads presented, returns usage restrictions and limi-tations of the aircraft and the weapons load. The RNS module evaluates user-selected weapons employment planning. Be-tween the two modules, the planner can create legal and safe loads, determine flight restrictions, create safe weapon release sequences and determine weapons delivery restrictions throughout the entire flight scenario. This paper is a descrip-tion of the two modules, the development environment, sys-tem growth, change management problems, and the scope of changes incorporated between the first release of Weapon Employment Planning Software (WEPS) in 2001 and the lat-est certified version.
