 now let's look at same problem where find out the average inventory level इस पूलिसी के बेस के अपर हमारा अवरीज इंवेंट्री लेवल क्या होगा आन देन भी विल फाँईडाउड गे तोतल कोस्ट हम क्या इंकर कार रहे हैं बेस्ट आन देस पूलिसी ये जो हम ने बनाई हूँए है के पीरियार्ट एक हम ने 0.991 अवरी मन्त अम इसका चेक करेंगे इंवेंट्री रवू करेंगे और जितना भी मेखसिमम इंवेंट्री जोगे 30,495 ती उसके दरम्यान जो दिफरन्स है उसका हम अडर पलेस करेंगे तो उस बेसिस पर हमारा अवरीज इंवेंट्री लेवल के आता है और अवरीज इंवेंट्री लेवल के बजेए पर फेर मरी चोटल गोस्त कई आती है इस सिस्टम की तो वी कैन पार अवरीज इंवेंट्री लेवल आती है अगर वह लिए वह पोझा में दा After the order point, we will be demultiplied by the review period, this is the cycle inventory, the divide of these two is the average inventory. I have told you that the beginning inventory plus the ending inventory is divided by two and the ending inventory is zero. The beginning inventory is divided by two and the end inventory is divided by three. 780 ुنि twists ु khe humari average inventory level aari. इस के basis ke pr hum total cost calculate krhe total relevant cost ki joh equation hai यह जो है this is that equation यह जो है this is your annual ordering cost a number of orders multiplied by ordering cost per order this is your average holding cost annual holding cost without safety stock this is what we used that was q divided by 2 but because there is a periodic review, there is no q the review period is multiplied by d divided by 2 and then we multiplied it by inventory holding cost per unit this is our safety stock multiplied by and holding cost per unit this is also added to it and the fourth figure in this case is the stock out cost we incorporated it into this so if we see the figure this is the value of substitute this is the value of loss function at z is equal to 0.67 so on that basis we put it here all the other values we have already calculated we have taken some data so we have substituted all these values so the total cost figure we have is of 403.06 dollars this is the annual total cost for this policy on this basis, if we determine the service level what is the service level of this policy if we look at the service level of the fill rate it was 75% in this stock but on the basis of the fill rate if we use this formula this is 0.933 that is substantially higher than your in stock probability so in the periodic review because here we are protecting the entire system so here our fill rate is 0.933 instead of 0.75 our in stock probability
