Strategic stock

A Stock can be seen like a storage capacity making it possible a company to provide a level of service (times or availability) when production capacity alone is not capable capacity to satisfy the customer orders. The stock strategic ( safety stock ) plays the same part but makes it possible to be guarded against various forms of uncertainty.

The strategic stock can be regarded as a complement with the stock of fascinating operation of account the uncertainty of the real request and restocking and the satisfaction of the customer.

Calculation of the strategic stock

The calculation of the strategic stock necessary to guarantee a level of statisfaction customer takes account of:

• average Request $N\_\; \{p\}$

• Standard deviation of the request $\backslash \; sigma\; \backslash ,\; \_\; \{Np\}$
• Intermediate duration of restocking $R$
• Standard deviation of the duration of restocking $\backslash \; sigma\; \backslash ,\; \_\; \{R\}$
• Z-score of satisfaction customer (95%, z=1.65) $z$

Strategic stock $S\_\; \{S\}\; =z\; \backslash \; sqrt\; \{R\; \backslash \; sigma\; \backslash ,\; \_\; \{Np\}\; ^\; \{2\}\; +N\_\; \{p\}\; ^\; \{2\}\; \backslash \; sigma\; \backslash ,\; \_\; \{R\}\; ^\; \{2\}\}$

The strategic stock can be also calculated starting from other concepts:

Stock strategic = Stock of alarm (which starts the order) - minimum Stock (consumed during the delivery period).

Calculation of the reorder point

The reorder point is the moment when the production must be launched to make it possible to guarantee the level of satisfaction customer.

Not restocking $S\_\; \{C\}\; =N\_\; \{p\}\; R+S\_\; \{S\}$
