Discuss the methods used to determine safety stock when the stock out cost is known and when the stock out cost is unknown.
Safety stock is common word used by logistic companies to determine the level of extra stock that is maintained to migrate from stockouts i.e a situvation that a product is out of stock.The safety stock calculation is based on
1.Demand of a particular commodity,
2.Lead time
3.Service time(it is defined as the desired probability of meeting the demand)
using this as inputs we have a method called reorder point method to calculate the safety stock.
the safety stock(SS) is calculated using the formula.
SS=
where is the service level
sigma(l) is defined as standard deviation of mean time
E(l) -mean
then the reorder point is calculated as
ROP=E(L).E(D)+SS

i. Identify and discuss methods used to control noise pollution. ii. Discuss how noise pollution level is measured and calculated. iii. A machine with an overall noise level of 80 dB is placed in a room with another machine putting out 90 dB. a. What will be the sound level in the room? b. How long should workers be in such a room in one working day, based on the permitted noise levels criteria?
Discuss examples in which statistical methods are used, or have been used, in chemical analysis. Identify the statistical methods used, and describe the implementation of these methods as well as the benefits obtained from their use. Explain using f-Test, t-Test, Grub's test, methods in least-squares/linear regression analysis, and multivariate analysis (ANOVA). Do not use methods in principle components analysis (PCA), PCR, Simplex optimization.

In thermochemistry, we used Hess Law to determine ethanlpy change of unknown reaction from the known reactions. Same approach can be used to find the Gibbs energy change for a unknown reaction too. Complete the following problem using “Hess Law” approach. Find ∆Grxn° for the reaction: 3 Cs+4 H2g→ C3H8g Use the following reactions with known ΔG’s: C3H8g+5 O2g→3 CO2g+4 H2Og . ∆Grxn°=-2074 kJ Cs+O2g→CO2g ∆Grxn°=-394.4 kJ 2 H2g+O2g→2 H2Og ∆Grxn°=-457.1 kJ
Discuss employee comparison methods as they may be used in performance evaluation. Provide examples of at least two such methods. What are the advantages of using employee comparison methods to evaluate employees? What are the disadvantages?
Q1) Which of the following relationships hold true for safety stock? A. the greater the risk of running out of stock, the smaller the safety of stock. B. the larger the opportunity cost of the funds invested in inventory, the larger the safety stock. C. the greater the uncertainty associated with forecasted demand, the smaller the safety stock. D. the higher the profit margin per unit, the higher the safety stock necessary.
