<h2 class="page-title">What is Newsvendor Problem?</h2>
<div class="title-info"> The newsvendor problem is to make a single-period procurement decision of a single product under stochastic demand</div>
<h3>Newsvendor Framework:</h3>
<ul>
<li> One chance to decide on the stocking quantity of the product </li> <br>
<li> Demand for the product is uncertain </li> <br>
<li> Known marginal profit for each unit sold and known marginal loss for the ones that are bought and not sold </li> <br>
<li> Goal : Maximize expected profit</strong></li>
</ul>
<p>&nbsp;</p>
<p><strong></p>

<h3>Examples where the Newsvendor Framework is appropriate:</h3>
<ul>
<li><strong>Perishable Goods</strong>
<ul>
<li>Meals in a Cafeteria</li> <br>
<li>Dairy foods</li>
