In this paper, we present the IBM Carbon Analyzer Tool, a
software solution that models and quantifies carbon emissions and
explores ways to reduce emissions through advanced analytics. The
tool is designed to manage carbon emissions associated with the
support logistics for an assembly manufacturing operation. The
tool has four analytical modules. A shipment analysis module
calculates carbon emissions from transportation activities and
analyzes opportunities for reducing emissions by changing fuel
types of vehicles and using larger vehicles that permit consolidated
shipments. A sourcing analysis module compares sourcing
alternatives, including changes to supplier locations, routing of
shipments, frequency of orders, and transportation modes. A
scenario analysis module explores various consolidation policies to
minimize transportation, inventory, and carbon costs, subject to
inventory availability requirements. A sensitivity analysis module
quantifies the effects of changes to uncontrollable and uncertain
inputs, such as manufacturing demand for components, carbon
prices, and supplier reliability. The tool makes use of a Java™-based
graphical user interface and an IBM DB2® (Database 2™)
platform to manage input and output data. A pilot implementation
of the solution, using actual customer data, showed that emissions
and transportation costs can be reduced simultaneously by
optimizing vehicle use, fuel types, and shipment consolidation.
Achieving a 20%-30% reduction in emission was possible with
minimal cost increase.
