Explanation:

Migration refers to the movement of a group of people from one geographical region (location) to another geographical destination in search of better living conditions, work or social amenities.

Migration selectivity can be defined as the likelihood or tendency that a subset (part) of a group of people are going to move (migrate) out of a particular geographical location or area.

Some of the factors that influence migration selectivity are income level, age, education, gender etc.

One way migration affects various locations across the world such as Texas, Brazil, Paris, Rome, Stuttgart, Kyiv, etc., includes the establishment of different restaurants. For example, the establishment of KFC, McDonalds, Mr Biggs were influenced by the migration of people across European cities and as such served as tourist attraction centers, thus, positively affecting the character of these places.

Answer:

$4,265.55

Explanation:

Future value = $120,000

Interest rate (i) = 5%

Annual deposit = ?

Time period (n) = 18 year

Since deposit are to be made at the beginning of each year, hence the relevant factor table to be used is future value annuity due factor table.

Future value = Annual deposit x future value annuity due factor (i%, n)

120,000 = Annual deposit x FVADF (5%, 18period)

120,000 = Annual deposit x 28.13238

Annual deposit = 120,000/28.13238

=$4,265.547

=$4,265.55

The bank is working to develop an efficient work schedule for full-time and part-time tellers. The schedule must provide for eff

Kitty [74]

Answer:

The solution is given below.

Explanation:

It is a practical, complex scheduling problem that can be easily modelled and solved as IP. Note that part time and full time employees are paid at different rates. So, it is important that the bank operates to provide required service level (indicated by the number of tellers per hour) while minimizing total cost due to staff salary.

We use x as full time and y as part time staff.

It would help if you construct a table as shown below to better analyze the problem before attempting to model it. Red shows work hrs of full time staff and green is for part timers. Just follow their work hour rules.

So, full timers have 3 options:

(i) start at 9 – work till 1pm, take 1 hr break, then work 2 – 5 pm

(ii) start at 10 – work till 2pm, take 1 hr break, then work 3 – 6 pm

(iii) start at 11 – work till 3pm, take 1 hr break, then work 4 – 7 pm

that’s all… bank closes at 7 pm.

However, part timers don’t have 1 hr break. They work straight 4 hrs and leave. See green cells above to understand their alternatives.

Now, decision variables should include this work hour information. Here goes their definition. You must clearly define decision variables in exam, otherwise, the model is meaningless.

X9 = number of full time staff who start at 9 and follow the hour-related rule (no need to specify more details; those are already undestood)

X10 = number of full time staff who start at 10 and follow the hour-related rule

X11 = number of full time staff who start at 11 and follow the hour-related rule

Y9 = number of part time staff who start at 9 and follow the hour-related rule

Y10 = number of part time staff who start at 10 and follow the hour-related rule

…. This way you define up to Y15.

You must also specify that:

Xi, Yi >=0, integers.

Objective Function:

Minimize Z = 105*(x9 + x10 + x11) + 32* (y9 + y10 + … + y 15)

You will need one “covering” constraint for each working hour. Both full and part-timers can “cover” the duty of each hour. Look at the color-coded table (above) column-wise. The 9:00-10:00 hour can be covered only by x9 and y9 staff; next hour by x9, x10, y9, y10 only,… and so on. So, the
