Waiting for Maintenance

Usually this state occurs to the machine while it fails and gets before a state of emergency maintenance. While a machine fails unexpectedly, but no spares/material are available to replace or no repairmen/tools are available or no information or because of non availability of any resource needed to restore the machine in operating condition, this state is resulted. The production loss is incurred by this state and the extent of the loss is unpredictable. This loss might be minimized to some extent by adopting a good inventory control strategy & policy.

Summarily, a plant or machine might be stated to be in one of the two states, namely, Up State or Down State. The Up State involve the states while the machine is available for production, i.e. on Production state, Production Outage while all other above mentioned states are down states during which the machine is not available for production.
