A deli is offering a special for its sandwiches. a customer will receive three free sandwiches for every five sandwiches purchas
ArbitrLikvidat [17]
We see that for every 8 sandwiches that the customer needs, he will pay for 5. Lets see how many groups of 8 sandwiches the order of 675 sandwiches contains. If we do Euclidean Division we see that there are 84 groups of 8 and that three sandwiches are the remainder. 675/8=84.375; Hence we have 84 groups and 0.375*8=3 sandwiches that remain. Thus, the customer would play for 84*5= 420 sandwiches if he had ordered 84 groups of 8 (namely 672 sandwiches). Since he needs another 3 sandwiches and there is no promotional offer for those, he will have to pay in total for 423 sandwiches. It is important to not divide the total number by 8 and then multiply it by 5; the customer gets the free sandwiches only if he completes an offer of 5 sandwiches, thus we have to group the sandwiches in octads and deal with the remainder separately.

Palin's Muffler Shop has one standard muffler that fits a large variety of cars. The shop wishes to establish a periodic review
forsale [732]

Answer:

A.) 270 units (b.) Increase

Explanation:

Given the following :

Annual demand (A) = 2870

Working days = 205

Review period (P) = 16 working days

Lead time (L) = 2 working days

Standard deviation (σ) = 6 per working day

Service probability = 76%

Therefore, z = NORMSINV(0.76) = 0.71

Average demand (D) = 2870 / 205 = 14

Optimum target level, (S) is given by the relation:

D×(P+L) + z×σ×√(P+L)

14×(16+2) + 0.71×6×√(16+2)

(14×18) + 4.26 × √18

252 + 4.26*4.242

252 + 18.07

= 270.07 units = 270 units

B) If service probability increases to 97%, Z will automatically increase, hence a corresponding increase in the optimal target level.
