Chapter 9.6, Problem 10P
A
Summary Introduction
Interpretation: The sequence of the jobs is to be determined in order to minimize mean flow time.
Concept Introduction: The activities under a project are programmed based on the needs of the individual and attaining ease is the priority of the individual. The mean flow time is the average time that a task takes to be processed within a computer system.
B
Summary Introduction
Interpretation:The sequence of the jobs is to be determined in order to minimize the number of tardy jobs.
Concept Introduction: The activities under a project are programmed based on the needs of the individual and attaining ease is the priority of the individual.Tardiness is the delay in executing a certain job to be executed within a computer system.
C
Summary Introduction
Interpretation: The sequence of the jobs is to be determined in order to minimize maximum lateness.
Concept Introduction: The activities under a project are programmed based on the needs of the individual and attaining ease is the priority of the individual.The EDD rule will be aiding for minimizing the maximum lateness of the project.
D

Sam's Pet Hotel operates 51 weeks per year, 6 days per week, and uses a continuous review inventory system. It purchases kitty litter for $11.00 per bag.
The following information is available about these bags:
> Demand
95 bags/week
> Order cost $52.00/order
> Annual holding cost = 25 percent of cost
> Desired cycle-service level = 80 percent
>Lead time 4 weeks (24 working days)
> Standard deviation of weekly demand = 15 bags
> Current on-hand inventory is 320 bags, with no open orders or backorders.
a. Suppose that the weekly demand forecast of 95 bags is incorrect and actual demand averages only 75 bags per week. How much higher will total
costs be, owing to the distorted EOQ caused by this forecast error?
The costs will be $
higher owing to the error in EOQ. (Enter your response rounded to two decimal places.)

C Consider the following m... As discussed in Section 8.3, the Markowitz model uses the variance of the portfolio as the measure of risk. However, variance includes deviations both below and above the mean return. Semivariance includes only deviations below the mean and is considered by many to be a better measure of risk. (a) Develop a model that minimizes semivariance for the Hauck Financial data given in the file HauckData with a required return of 10%. Assume that the five planning scenarios in the Hauck Financial Services model are equally likely to occur. Hint: Modify model (8.10)-(8.19).
