Paper Manufacturing
A major paper manufacturer utilizes models to plan production, make long-term budget projections, and warn of impending shortages.

 

Plywood Mill Optimizing

More than 10 of the country's plywood mills have been modeled, from the largest in the country to some medium-sized mills.  The models produced a re-allocation of veneer to a more profitable product mix, or a change in recipe.  One 2-plant model produced an average selling price increase of $ 6.35 per M38 (1.8% of revenue) over the same quarter in the prior (non-modeled) year.

 

Timber Harvest Optimizing

A harvest region with more than 300 stands of timber, 3 internal mills and 22 external destinations was modeled.  The mills were modeled by a return-to-log computation for each of the 15 log types modeled, producing a re-allocation of the timber destinations for 6% of the timber, and increasing profits by 2% of gross revenue.

 

Castings Manufacturing

A plant manufacturing castings was modeled to determine the profitability of different products, each of which is customer-specific.  This analysis also provided the basis for adjustment of prices.  A full cost-based model was built, including the allocation of investment costs to specific products, or classes of products.

Electronics Manufacturing

A group of PCB assembly machines in several lines was analyzed.  The result was a grouping of products by component similarity, and a sequencing to minimize downtime due to component changeovers.  Changeover downtime was reduced by 40%.  

 
Oil Refining

Several steps in the standard refining process were modeled, including an A&V Tower and a Cat Cracker.  The model reduced product waste due to feedstock changeover -- times were reduced 60%.
