If an interruption occurs in the supply tends institutions to stocks, and, if necessary, and used safety stock (which is a buffer stock against random to meet the deficit) for an emergency, it may be a delay in the arrival of inputs or expansion of use, any increase in the utilization factor for the time, you'll find the same institution in two cases:
Safety stock enough to cover the period of interruption: In this case there is no problem for the institution, but must be compensated later.
Safety stock is not sufficient to cover the use: here stop the production process, and thus no shortfall in internal organization, and show the cost of the deficit and the internal variable is the cost of increasingly well in terms of time, disruption, and the institution to bear the cost or affordable to the consumer.
If you do not stop interruptions in supply, there will be dangerous for the image of the company a private company that produces the production of functional, and when he performs safety stock of the input moving the institution to the stores security for output, you will find the same in the two cases: stock safety is enough or not enough, in the second case turns deficit internal to the external deficit, and it shows the external deficit and the costs are:
Unrealized gain and is a fixed cost.
Aversion and the cost is the size of the market transferred from the institution to other institutions.
Opportunity cost for organizations productivity because there are no obligations between them and the customers.
The costs of the deficit of internal + external deficit costs = cost of access.
