Points

Mark Gunther and Sony are trying to determine the safety stock $($SS$),$ Base Stock$($S$)$ and Order Quantity for its circuit cards using a Periodic Review Inventory Management System. It takes $25$ days for Sony to receive its cards, i$.$e$.,$ a lead$-$time of $25$ days, and Sony uses a review period $($I$)$ of $11$ days. Mark estimates that the daily demand for Sony is $250$ cards on average with a daily standard deviation of $70$ units. After long conversations with the management team, Samsung agrees to target a service level of $91\%.$ The z$-$score for $91\%$ service level is $1\mathrm{.}34.$
