ABSTRACT
<p><b>Abstract</b>—<it>Step-wise refinement</it> is a powerful paradigm for developing a complex program from a simple program by adding features incrementally. We present the <it>AHEAD</it> (<it>Algebraic Hierarchical Equations for Application Design</it>) model that shows how step-wise refinement scales to synthesize <it>multiple programs</it> and <it>multiple noncode representations</it>. AHEAD shows that software can have an elegant, hierarchical mathematical structure that is expressible as nested sets of equations. We review a tool set that supports AHEAD. As a demonstration of its viability, we have bootstrapped AHEAD tools from equational specifications, refining Java and non-Java artifacts automatically; a task that was accomplished only by ad hoc means previously.</p>
