The A&M Hobby Shop carries a line of radio-controlled model racing cars. Demand for the cars is assumed to be constant at a rate of 40 cars per month. The cars cost $60 each, and ordering costs are approximately $15 per order, regardless of the order size. The annual holding cost rate is 20%.

  1. Determine the economic order quantity and total annual cost under the assumption that no backorders are permitted. If required, round your answers to two decimal places.

    Q* =

    Total Cost = $  
  2. Using a $45 per-unit per-year backorder cost, determine the minimum cost inventory policy and total annual cost for the model racing cars. If required, round your answers to two decimal places.

JAVA. A palindrome is a word or a phrase that is the same when read both forward and backward.

java please. 

A palindrome is a word or a phrase that is the same when read both forward and backward. Examples are: "bob," "sees," or "never odd or even" (ignoring spaces). Write a program whose input is a word or phrase, and that outputs whether the input is a palindrome.

Ex: If the input is:

bob

the output is:

bob is a palindrome

Ex: If the input is:

bobby

the output is:

bobby is not a palindrome

Hint: Start by removing spaces. Then check if a string is equivalent to it's reverse.


Hint: Start by just handling single-word input, and submit for grading. Once passing single-word test cases, extend the program to handle phrases. If the input is a phrase, remove or ignore spaces.

Consider a process consisting of three resources. Assume there exists unlimited demand for the product, and that all activities are always performed in the following sequence. 

• Resource 1 has a processing time of 7 minutes per unit. 

• Resource 2 has a processing time of 4 minutes per unit. 

• Resource 3 has a processing time of 6 minutes per unit. 

All three resources are staffed by one worker and each worker gets paid $10 per hour. 

 

a. What is the cost of direct labor? 

b. What is the labor content? 

c. What is the average labor utilization? percent

Do not round your intermediate calculations.

d. Assume the demand rate is 18 units per hour. What is the takt time?

Write a program that reads an integer, a list of words, and a character.

13.14 LAB: Contains the character

Write a program that reads an integer, a list of words, and a character. The integer signifies how many words are in the list. The output of the program is every word in the list that contains the character at least once. Assume at least one word in the list will contain the given character.

Ex: If the input is:

Problem 2. The annual demand for a product is 15,600 units. The weekly demand is 300 units with a standard deviation of 90 units. The cost to place an order is $31.20, and the time from ordering to receipt is four weeks. The annual inventory carrying cost is $0.10 per unit. Find the reorder point necessary to provide a 98 percent service probability. Suppose the production manager is asked to reduce the safety stock of this time by 50 percent. If she does so, what will the new service probability be?

Annual demand = Annual holding cost ($) per units Ordering cost = EOQ (Economic Order quantity) = 2 DS H = our Weekly demand
