  2. On router D
    1. Ping <IP ADDRESS>

Capture the screen (screenshot 15) and place it with the related question below.  

Before continuing, answer question 6 below.  

Note: Now, it’s time to practice with OSPFv3. Unfortunately, because OSPF has automagic routing, the routing that was set before needs to be removed. Of course, one could just close the app and re-open it, but practice instead.  

  1. On router A type the following command:
    1. no ipv6 route 2001:db8:3c4d:2::/64 gi0/0
  2. On router B type the following command:
    1. no ipv6 route ::/0 gi0/0
  3. On router D type the following command:
    1. no ipv6 route 2001:db8:3c4d:1::/64 gi0/0
  4. On router E type the following command:
    1. no ipv6 route 2001:db8:3c4d:1::/64 gi0/0
  5. We aren’t doing this for router C.

Before continuing, answer question 7 below.  

  1. IRL, if IPv4 is not configured, RIDs need to be created for each router. On router A, define ospf 1 with RID 1.1.1.1 by typing the following commands:  
    1. ipv6 router ospf 1
    2. router-id 1.1.1.1
  2. Now, assign ospf 1 to the outside interface by typing the following commands:
    1. int gi0/0
    2. ipv6 ospf 1 area 0
    3. CTRL+Z
  3. Verify by typing the following commands:  
    1. sh ipv6 route
    2. sh ipv6 route ospf
    3. sh ipv6 int gi0/0
    4. sh ipv6 neighbor
  4. On router B, define ospf1 with RID 2.2.2.2, then assign OSPF 1 to f0/0 by typing the following commands:  
    1. ipv6 router ospf 1
    2. router-id 2.2.2.2
    3. int gi0/0
    4. ipv6 ospf 1 area 0
    5. CTRL+Z
  5. Verify by typing the following commands:  
    1. sh ipv6 route
    2. sh ipv6 route ospf
    3. sh ipv6 int gi0/0
    4. sh ipv6 neighbor
  6. Complete the same with routers C, D, & E, changing the “Router-id #.#.#.#” to be 3.3.3.3, 4.4.4.4, & 5.5.5.5, respectively.  On Router C, make sure that you issue the ipv6 ospf 1 area 0on both interfaces (gi0/0 & gi0/1).

Before continuing, answer question 8 below.  

  1. In order to confirm the ping, determine the ipv6 addresses for each router. These should all begin with 2001.  Do not use the FE80addresses as they are link-local addresses.  

Finish this assignment by completing question 9 below.

QUESTION 1

  1. Use the following scenario and data for all questions
    An auto service center provides two types of services, Tire Replacement (T) and Oil Change (O). About 30% of the customers are for Tire Replacement and the other 70% are for Oil Change. All customers are serviced on a first come first served basis. During regular hours, customers arrive at the service center according to the probability distribution in the following table

    Two technicians are working at the service center and both of them are skillful enough for both Tire Replacement and Oil Change. Once finishing the job for a customer, a technician will take care of the next customer waiting in line. When both technicians are idle, the one who finished the last job earlier will take care of the next incoming customer. The times taken by the two jobs by any of the technicians follow the probability distributions in the following tables. You are required to simulate the operations of the auto service center for 15 customers.

    Before answering the following questions, you may use the following tables to determine the cumulative probability distributions and assign random number intervals for customer arrivals, customer service types, and time needed for both types of services.

The management of a company is considering replacing a number of old looms in the mill’s weave room. The looms to be replaced are two 220-cm President looms, sixteen 135-cm President looms, and twenty-two 185-cm Draper X-P2 looms. The company may either replace the old looms with new ones of the same kind or buy 21 new shutterless Pignone looms. The first alternative requires the purchase of 40 new President and Draper looms and the scrapping of the old looms. The second alternative involves scrapping the 40 old looms, relocating 12 Picanol looms, and constructing a concrete floor, plus purchasing the 21 Pignone looms and various related equipment. Following are the revenue and expense predictions:

Description Alternative 1 Alternative 2
Machinery/related equipment $2,150,000 $900,000
Annual revenues due to the new looms $2,000,000 $1,500,000
Annual labour cost $250,000 $300,000
Annual O&M cost $1,000,000 $700,000
CCA Rate 30% 30%
Project life 8 years 8 years
Salvage value $100,000 $40,000

The corporate executives feel that various investment opportunities available for the mill will guarantee a rate of return on investment of at least (MARR) 10%. The mill’s marginal tax rate is 40%. Due to uncertainty, the following variabilities in estimates should be considered: revenues ± 30%, labour cost ± 40%, and annual O&M cost ± 20%. Assume that each of these variables can independently deviate from its base value.
a] Assuming that uncertain variables change once at a time, use NPW to conduct sensitivity analysis. Ideally, you should plot the relationship between percentage change in a variable and NPW.
b] Now consider that each variable can take only three possible outcome within the range of possible outcome: lowest value, base value, and highest value. Each outcome can happen with a probability: 0.15, 0.7, and 0.15, respectively. Considering the distributions of the three uncertain variables, predict the probability distribution of NPW for each alternative. Each NPW will have 27 possible outcome (3x3x3) and you are required to do that for each alternative.
c] If Alternative 1 is chosen over Alternative 2, what is the probability that this decision is correct?
Hints:
-do not forget to calculate income taxes and disposal tax effects
-You can you spreadsheet applications if you communicate your solution in a way which enables the teaching assistant to independently replicate your final answer. You can show sample calculations as a way to communicate with the teaching assistant.
-Please assume that the given MARR is market interest rate and all dollars are current.

Note: If not mentioned, [1] the half-year rule applies and [2] all rates are annual.

The goal of Java program implemented as part of this assignment is to build an Inventory...

The goal of Java program implemented as part of this assignment is to build an
Inventory Management System, from here on referred to as IMS, for a bookstore.
You will need to do the following tasks:
Requirement-1 – Create 3 different Arrays (15 pts)
(a) Create an array named items that will hold the following item names (strings)
- Pen
- Pencil
- Eraser
- Marker
- Notepad
(b) Create a second array named quantity, that will hold corresponding quantities
for items in the items array above. This will be populated through user inputs.
For each input you get from the user, be sure to check it is a number > 0. If
not, continue to ask the user for the right number.
Hint: User the handy-dandy Scanner to read user input, the if-else construct to
validate user input and the loop to repetitively ask for user input should you
get an unacceptable value
(c) Create a third array named price, that will hold price-per-item for the items
stored in the first array. The price point for each item should also come from
the user. For example, a notepad could be priced at $1.47, eraser at $0.76 etc.
As in the above case, for each price point input you get from the user, be sure
to check it is a number > 0. If not, continue to ask the user for the right
number for the item price.
The message, for example, could look like “Please enter price for a Notebook”
(d) Based on the type of data that needs to be stored in the above-mentioned
arrays, be sure to use the correct data type


Requirement-2 –Create Operations for an Inventory Manager role
(a) Show Functions List
Once the above data points have been correctly created, you will now need to
build the functional points (operations) for this IMS. But before we do that, we
need tell the user about operations that are available to be invoked by the
user, as part of this IMS. The 5 operations of the IMS are as follows. So, display
these operations to the user and ask the user to enter the letter for the
operation that the user wants to run.
- Print Inventory (p)
- Check for Low Inventory (c)
- Highest/Lowest value inventory Items (h)
- Total Inventory Value (t)
- Exit System (e)
Sample output should look something like the following:
Welcome to IMS. Please select a function from the following:
Print Inventory (p)
Check for Low Inventory (c)
Highest/Lowest value inventory Items (h)
Total Inventory Value (t)
Exit System (e)
(b) PrintInventory (15 pts)
This operation should print inventory, starting with the header, in the
following format
Item_Name Quantity Price Total_Inventory_Value
Eraser 14 $.95 $13.30
Notebook 10 $1.47 $14.70
….
Note:
The last column will show a computed value (price * quantity) for the item
At the end of this operation, go back to displaying the 5 operations that user
can choose from, as in (a) above
(c) checkForInventory
This operation checks for items that have quantity less than 5, and then prints
them in the same format as in (b) above. For example:
Items with quantity less that 5:
Item_Name Quantity Price Total_Inventory_Value
Notebook 7 $1.47 $10.29
Marker 4 $1.02 $4.08
….
….
At the end of this operation, go back to displaying the 5 operations that user
can choose from, as in (a) above
(d) highestAndLowestValueItems
This operation finds the highest, and lowest, value item(s) in inventory,
computed by multiplying the quantity with the price for that item, and then
prints them in the same format as in (b) above.
Highest Inventory Value Items:
Item_Name Quantity Price Total_Inventory_Value
Notebook 7 $1.47 $10.29
Marker 4 $1.02 $4.08
….
Lowest Inventory Value Items:
Item_Name Quantity Price Total_Inventory_Value
Pencil 4 $.74 $2.96
Marker 2 $1.02 $2.04
….
At the end of this operation, go back to displaying the 5 operations that user
can choose from, as in (a) above
(e) totalInventoryValue
This operation simply prints the Grand Total value of the entire inventory. This
will essentially be the summation of all individual total values of each item in
the inventory
At the end of this operation, go back to displaying the 5 operations that user
can choose from, as in (a) above
(f) exit
This operation simply exits the program
