Managing Surplus Maintenance, Repair and Operations Inventory

Posted by SiewMun Ha

Surplus Maintenance, Repair and Operations (MRO) inventory, defined as stock-on-hand in excess of maximum levels, is an unfortunate reality at many asset-intensive organizations. Surplus inventory is undesirable because it increases holding cost and also ties up scarce resources – capital, warehouse space and manpower – at the expense of items that are more urgently needed by the organization. It is not uncommon for surplus inventory to make up a significant fraction of total inventory at many organizations and, since it increases cost but not inventory performance, it represents a logical target for inventory-reduction initiatives.

The application of Machine Learning has the potential to address a common problem in MRO inventory and maintenance management. Machine Learning is a branch of Artificial Intelligence (AI) with algorithms that can learn from and make predictions on data. This capability can be deployed to infer missing pieces of critical information to improve inventory and maintenance management.

Multi-Location Inventory Optimization

Posted by SiewMun Ha

Many asset-intensive organizations stock Maintenance, Repair and Operations (MRO) inventory at multiple locations to cater to geographically-distributed demand. Where there are common items used at the different locations, it is advantageous for them to share this common inventory for greater efficiency. In doing so, they set up a network of interacting nodes that can be optimized to obtain additional inventory savings. Achieving these savings, however, requires a network-centric analysis to optimize the stocking decisions at each of the nodes, such that the global inventory in the network as a whole is optimal with respect to defined management objectives. Such an analysis is significantly more complex than that for a stand-alone location because the analysis must consider the interactions between the nodes, the stochastic nature of MRO inventory demand and supply as well as practical operational constraints.

Optimal Inventory Management for an Asset Retirement Event

Posted by SiewMun Ha

A discrete step reduction in future demand occurs in MRO inventory optimization when an asset is taken off line permanently. This might happen, for example, at a utility or oil and gas company when a plant is decommissioned, or maybe a mining company when a mine is shut down. What is the optimal way to manage MRO spares and inventory in such a scenario?
