  In order to make the task, description of planning domains and problems, more
comprehensive for non-experts in planning, the visual representation has been
used in planning domain modeling in recent years. However, current knowledge
engineering tools with visual modeling, like itSIMPLE (Vaquero et al. 2012) and
VIZ (Vodr\'a\v{z}ka and Chrpa 2010), are less efficient than the traditional
method of hand-coding by a PDDL expert using a text editor, and rarely involved
in finetuning planning domains depending on the plan validation. Aim at this,
we present an integrated development environment KAVI for planning domain
modeling inspired by itSIMPLE and VIZ. KAVI using an abstract domain knowledge
base to improve the efficiency of planning domain visual modeling. By
integrating planners and a plan validator, KAVI proposes a method to fine-tune
planning domains based on the plan validation.
