Inventory; the timely availability of spares parts, common supply items and tools is essential to both preventive and reactive maintenance. Preventive maintenance allows for some advance planning, but break down does not give us any buffer time.
An ABC analysis of inventory holding will indicate that the bulk of the material stored are from the A category – low-cost, frequently used, bulk requirement type. The B category items are also fairly large in number, but the C category would be less in numbers, but high in cost.
I came across an article on Inventory control and CMMS to which the link is given below:
A good CMMS will have an inventory module that allows to do analysis of inventory usage pattern, inventory carrying costs, inventory management etc.
Please read the article and be enlightened.
