<hr/><a name="_details"></a><h2>Detailed Description</h2>
<p>This solver implements a heuristic algorithm for planning demands. </p>
<p>One by one the demands are processed. The demand will consume step by step any upstream materials, respecting all constraints on its path.<br/>
The solver supports all planning constraints as defined in <a class="el" href="a00171.html" title="This class is an implementation of the "visitor" design pattern. It is...">Solver</a> class.<br/>
See the documentation of the different solve methods to understand the functionality in more detail.</p>
<p>The logging levels have the following meaning:</p>
<ul>
<li>0: Silent operation. Default logging level.</li>
<li>1: Show solver progress for each demand.</li>
<li>2: Show the complete ask&reply communication of the solver.</li>
<li>3: Trace the status of all entities. </li>
</ul>

<p>Behavior of this solver method:</p>
<ul>
<li>Consider 0 as the hard minimum limit. It is not possible to plan with a 'hard' safety stock reservation.</li>
<li>Minimum inventory is treated as a 'wish' inventory. When replenishing a buffer we try to satisfy the minimum target. If that turns out not to be possible we use whatever available supply for satisfying the demand first.</li>
<li>Planning for the minimum target is part of planning a demand. There is no planning run independent of demand to satisfy the minimum target.<br/>
E.g. If a buffer has no demand on it, the solver won't try to replenish to the minimum target.<br/>
E.g. If the minimum target increases after the latest date required for satisfying a certain demand that change will not be considered.</li>
<li>The solver completely ignores the maximum target.</li>
