You are selling a product that shows a clear growth trend in its forecasted sales but you need to procure a product from a plant that is part of your organization: this product is manufactured in lots of more than two weeks demand coverage at a time in the "make" plant it has to be transported (send to you) in containers no greater than 800 units and on smaller than 400 units. you also need to make sure that the making plant is able to identify one special container per shipment only, as a material requirement every time they make a production run for your product.
you also need to put together a production plan for the next year using you plant "Sales and Operations Planning (SOP)" management process to incorporate in your production plan a target of 7days of inventory coverage at the end of the end of each month.
