Exercise 4-15: Items arrive from an inventory-picking system according to an exponential interarrival distribution with mean 1.1 (all times are in minutes), with the first arrival at time 0. Upon arrival, the items are packed by one of four identical packers, with a single queue "feeding" all four packers. The packing time is TRIA(2.75,3.3,4.0). Packed boxes are then separated by type (each box has an independent probability of 0.2 of being international, and the rest are domestic), and sent to shipping. There is a single shipper for international packages and two shippers for domestic packages with a single queue feeding the two domestic shippers. The international shipping time is TRIA(2.2, 3.3,4.8), and the domestic shipping time is TRIA(1.7,2.0,2.7). This packing system works three 8-hour shifts, 5 days a week. All the packers and shippers are given a 15-minute break 2 hours into their shift, a 30-minute lunch break 4 hours into their shift, and a second 15-minute break 6 hours into their shift; use the Wait Schedule Rule. Run the simulation for a single replication of 2 weeks (10 working days) to determine the average and maximum number of items or boxes in each of the three queues (put a text box in your model reporting these output values). Animate your model, including a Resource animation, and a change in the appearance of entities after they're packed into a box.

Answers

Answer 1

In the given scenario, a simulation model is required to analyze the packing and shipping process in an inventory system. The model operates for a single replication of 2 weeks (10 working days) and aims to determine the average and maximum number of items or boxes in each of the three queues.

The simulation model consists of several components: item arrivals, packers, domestic shippers, and an international shipper. Item arrivals follow an exponential distribution with a mean of 1.1 minutes.

The packing time follows a triangular distribution (TRIA) with parameters (2.75, 3.3, 4.0). Packed boxes are then separated into international and domestic types, and each type undergoes shipping with their respective triangular distribution times.

The simulation model should be animated to visually represent the process flow. Additionally, the model should incorporate break schedules for packers and shippers using the Wait Schedule Rule, which includes a 15-minute break at 2 hours, a 30-minute lunch break at 4 hours, and a second 15-minute break at 6 hours into their shifts.

By running the simulation model for the specified duration, we can collect data on the average and maximum number of items or boxes in each of the three queues.

This information can be presented in a text box within the model for easy reference and analysis.

Under the Corporations Act 2001, company directors are bound by a number of legal duties which govern the way in which they exercise their powers and functions. One of these duties - the s 180(1) duty of care and diligence - provides that company directors must exercise their powers and discharge their duties with the degree of care and diligence that a reasonable person in their circumstances would exercise. Recently, there has been much discussion about how this duty applies to climate change and what exactly company directors would be required to do to ensure they are managing the financial risks posed by climate change with the required level of care and diligence. From the list below, which of the statements best describes what is required of company directors in relation to climate change? Select one: a. Given the financial risks posed by climate change, company directors must develop business strategies to transition their companies away from climate-damaging activities as soon as possible, including immediately phasing out activities such as fossil fuel development and exploitation. b.

Suppose the Fed pays no interest on bank reserves.

A. 110 B. 70 C. 77 D. 7.7 If the interest rate on the loans increases, then the opportunity cost of the reserves____________

Answers

If the Fed pays no interest on bank reserves, and the reserve requirement is 11%, the banks would lose 7.70 on every 1,000 in deposits in forgone interest (after rounding to the nearest two decimal place).

This is because the reserve requirement is the percentage of deposits that banks are required to hold in reserve, which means they cannot lend that portion of the deposits and earn interest on it.

At an interest rate of 7%, the forgone interest on the reserve requirement is calculated as follows:

Reserves = Deposit × Reserve

Requirement= 1,000 × 11% = 110

Forgone Interest = Reserves × Interest Rate= 110 × 7% = 7.70

Banks would lose 7.70 on every 1,000 in deposits in forgone interest due to the reserve requirement (after rounding to the nearest two decimal place).

If the interest rate on loans increases, then the opportunity cost of the reserves would also increase.

This is because banks would be able to earn more on loans than they would by holding reserves, making the opportunity cost of holding reserves higher.

The total amount of dollars received (after accounting for the premium paid) is $6,872,500.

As per data,

Amount of receivables from New Zealand firms = $12.5 million,

Premium = $0.03,

When the option is exercised, the firm will receive the exercise price per dollar of the receivables from the option writer.

If the exercise price is more than the spot rate on the exercise date, the firm will exercise the option. Otherwise, the firm will sell its foreign currency receivables in the spot market.

So, the total amount of dollars received (after accounting for the premium paid) can be calculated as follows:

Total amount of dollars received = Exercise price × Amount of receivables − Premium Amount of receivables from New Zealand firms

Substitute all values respectively,

Total amount of dollars received = $0.55 × $12.5 million − $0.03

Total amount of dollars received = $6,872,500

Jaclyn Biggs, who files as a head of household, never paid AMT before 2021. In 2021 , her regular tax liability was \( \$ 102,220 \) which included \( \$ 39,900 \) capital gain taxe

Answers

The Alternative Minimum Tax (AMT) is an additional tax paid by taxpayers who earn high income, often used by taxpayers who claim a lot of exemptions or deductions to reduce their federal tax liability.

The amount of AMT due is the amount by which the AMT exceeds the taxpayer's regular tax liability. If the AMT is less than or equal to the taxpayer's regular tax liability, the taxpayer is not liable for the AMT.

Head of Household In 2021, Jaclyn Biggs, who files as a head of household, had a regular tax liability of $102,220, which included capital gain taxes of $39,900. Before 2021, Jaclyn Biggs had never paid the AMT.

The following steps are taken to calculate the AMT for a head of household filer:

Step 1: Calculate the head of household's alternative minimum taxable income (AMTI).The AMTI is calculated as follows:

AMTI = Taxable income + Adjustment and preferences

Step 2: Determine the head of household's AMT tax bracket. AM rate Income limit10% $0 - $14,60020% $14,600 - $56,00030% $56,000 - $132,20035% $132,200 - $213,20037% Over $213,200

Step 3: Calculate the amount of Alternative Minimum Tax Due. The AMT is calculated as follows:

Alternative Minimum Tax Due = AMT Rate × (AMTI - Exemption) - AMT Credit

Step 4: Determine whether the taxpayer must pay the AMT or the regular tax liability.

The amount of AMT due is the amount by which the AMT exceeds the taxpayer's regular tax liability. If the AMT is less than or equal to the taxpayer's regular tax liability, the taxpayer is not liable for the AMT.

Since the AMT is less than her regular tax liability of $102,220, Jaclyn Biggs is not liable for the AMT.

Hence, the amount of Alternative Minimum Tax (AMT) that Jaclyn Biggs must pay is $0.

Kelly-Lambing, Inc., a builder of government contracted small ships, has a steady work force of 10 very skilled craftspeople. These workers can supply 2,440 labor-hours each per year. Kelly-Lambing is about to undertake a new contract, building a new style of boat. The first boat is expected to take 6,100 hours to complete. The firm thinks that 80% is the expected learning rate. What is the firm's "capacity" to make these boats-that is, how many units can the firm make in 1 year? If the operations manager can increase the learning rate to 75% instead of 80%, how many units can the firm make? (Round all numerical responses in this exercise to the nearest whole number.)

Answers

In order to calculate the firm's capacity to make boats, it is important to know that the first boat requires 6,100 labor hours to complete. Since the skilled workers can supply 2,440 labor hours per person per year, the total labor hours of the workforce are:

10 workers × 2,440 labor-hours/worker/year = 24,400 labor-hours/year

To calculate the firm's capacity, the first step is to apply the expected learning rate of 80%. The formula for learning curves is:

Y = aX^b

where Y is the time required for the nth unit of output, a is the time required for the first unit of output, b is the log of the learning rate divided by the log of 2, X is the cumulative number of units produced, and n is the number of the unit being produced.

To find the capacity, the cumulative number of units produced is divided by the number of hours in a year (2,080):

Units produced = Hours available ÷ Hours per unit

Y = aX^bY = 6,100 × (1/1)^log 0.80 ÷ log 2 = 6,100 × 1 = 6,100

Therefore, the company's capacity to produce the new style of boat is one boat per year.

How is activity-based costing different from traditional costing systems? If a restaurant decided to use an activity-based costing system, please share 1-2 examples at each of the following levels: Customer, Group, Service and Facility.

Answers

Activity-based costing is a type of costing system that determines the cost of each activity or operation in the production process to calculate the cost of a product. The method is considered an alternative to traditional costing methods. Activity-based costing is different from traditional costing systems in the following ways:

In traditional costing methods, the overhead costs are allocated to products using predetermined overhead rates. On the other hand, activity-based costing assigns overhead costs to activities or operations and then to products based on the number of activities that each product uses. In this way, activity-based costing ensures that the cost of each activity is allocated accurately.

In traditional costing systems, the cost of a product is determined based on its direct labor and materials costs. In contrast, activity-based costing takes into account the indirect costs that are associated with the production process. Indirect costs can include expenses such as utilities, rent, and maintenance.

If a restaurant decided to use an activity-based costing system, the following are examples of the cost at different levels:

Customer level:

An example of activity-based costing at the customer level would be the cost of preparing food for a specific customer. This can include the cost of ingredients, labor, and equipment required to prepare the meal. The cost of serving the meal to the customer would also be included.

Group level:

An example of activity-based costing at the group level would be the cost of preparing and serving food for a specific group of customers. This can include the cost of ingredients, labor, and equipment required to prepare the meal. The cost of serving the meal to the group would also be included.

Service level:

An example of activity-based costing at the service level would be the cost of providing a specific service to a customer, such as the cost of taking an order, preparing a drink, or cleaning up after a meal. The cost of providing a specific service would be determined based on the activities involved in providing that service.

Facility level:

Answers

A homeowner with an existing mortgage loan of 150,000 at an 8% interest rate with a remaining term of 10 years and monthly payments.The monthly payment for the old loan can be calculated using an amortization formula. The formula for calculating the monthly payment of a mortgage loan is given as:

Where:P = monthly payment

L = loan amount

I = interest rate (annual interest rate divided by 12 months)

N = term of the loan (number of months)

Plugging in the values, we have:

[tex]P = 150,000 * (0.08 / 12) * [(1 + (0.08 / 12))^120] / [(1 + (0.08 / 12))^120 - 1][/tex]

P = 1,795.51

Rounded to two decimal places, the monthly payment on the old loan is 1,795.51.Suppose the homeowner wants to replace this loan with a new loan at an interest rate of 6%, and they will pay 8% of the outstanding loan amount as the cost to refinance. The outstanding loan amount is simply the remaining balance on the old loan.

Therefore, the cost to refinance is:

Cost to refinance = 8% * 150,000

Cost to refinance = 12,000

To calculate the new loan amount, the cost to refinance is subtracted from the remaining balance on the old loan:

New loan amount = 150,000 - 12,000 n

New loan amount = 138,000

Now that we have the new loan amount and the interest rate, we can use the same formula to calculate the monthly payment of the new loan:

[tex]P = 138,000 * (0.06 / 12) * [(1 + (0.06 / 12))^120] / [(1 + (0.06 / 12))^120 - 1][/tex]

P = 828.83

Rounded to two decimal places, the monthly payment on the new loan is 828.83. Therefore, the homeowner can save 966.68 per month by refinancing their mortgage loan.

There are no debtors at the start of January. One month’s credit is allowed to customers.
What is the budgeted cash received in each month?

Answers

The budgeted cash received in each month would be the sales amount for that month, as no debtors exist and one month's credit is allowed.

January: $12,000

February: $13,000

March: $14,000

April: $13,500

May: $12,600

June: $11,100

Since one month's credit is allowed to customers, the cash received in each month will be the sales budget for that month plus the cash received from the previous month's sales.

The Marginal Rate of Substitution of the consumer has the following expression M R S equals negative fraction numerator 2 space x subscript 2 over denominator x subscript 1 end fraction, and it takes the value of -3 in the optimal choice of the consumer. The correct option is (a) and (b).

It means that the consumer optimally chooses to consume her own initial endowments. For any given endowment, the negative of the slope of the indifference curve at a certain point is the MRS. If the slope is steeper, the MRS is more negative. If the slope is gentler, the MRS is less negative, and vice versa. The negative of the MRS is the slope of the indifference curve at the optimum point. As a result, the slope of the indifference curve at the optimum point in the problem is 3/2.

Thus, the problem's optimal solution is:

This indicates that the optimal choice of the consumer is at point A (4, 6), which is the endowment e5 (x1 = 4, x2 = 6). The other endowments are inconsistent with the problem's optimal solution.

Endowments that are inconsistent with the problem's optimal solution are:

w1 = 2, w2 = 3, and

w1 = 3, w2 = 2 (e1 and e2).

w1 = 8, w2 = 12, and

Consider our IS/LM/BOP analysis. Suppose also that we are in a fixed price, fixed exchange rate setup (with automatic money supply adjustment).

Answers

An increase in the money supply would cause the interest rate, r, to rise, but national income, Y, to fall if the capital account were highly interest sensitive (such that the BOP curve is flatter than the LM curve) when considering the IS/LM/BOP analysis in a fixed price, fixed exchange rate setup (with automatic money supply adjustment).

Therefore, the answer is: the interest rate, r, to rise, but national income, Y, to fall .Let's see the reason behind this :In the context of the IS/LM/BOP model, a fixed exchange rate regime necessitates that the central bank takes on the obligation of maintaining the exchange rate by intervening in the foreign exchange market. To keep the exchange rate steady, the central bank must make continuous adjustments to the supply of money in response to capital inflows or outflows. The LM curve shifts to the right when there is a monetary expansion, and the LM curve shifts to the left when there is a monetary contraction .The BOP curve shifts upward when there is an increase in the interest rate differential and downward when there is a decrease in the interest rate differential. The capital account is more interest-sensitive than the LM curve when the BOP curve is flatter than the LM curve .When the capital account is highly interest-sensitive and the BOP curve is flatter than the LM curve, an increase in the money supply will cause the interest rate to rise and national income to fall. Thus, we can conclude that an increase in the money supply would cause the interest rate, r, to rise, but national income, Y, to fall.

you still want to pay annuities for months 48 and 60, in the amount of $5
000 each, what is the value of the last 24 annuities that remain to be paid to the
new interest rate?

Answers

The problem is about compound interest with varying interest rates for different periods. It involves finding the present value of a series of future payments. Let's see how to solve the problem.

Monthly interest rate = 15%/12 = 0.0125

New monthly interest rate = 48%/12 = 0.04

Payment amount = $5000

Present value of each annuity payment is calculated as:

PMT/(1 + r)n

where PMT is the payment amount, r is the monthly interest rate, and n is the number of months.The present value of the annuity payments made at months 12, 24, and 36 is:P1 = 5000/(1+0.0125)12 + 5000/(1+0.0125)24 + 5000/(1+0.0125)36

= 43174.34

The present value of the annuity payments to be made at months 48 and 60 is:P2 = 5000/(1+0.04)48 + 5000/(1+0.04)60 = 61812.16The total present value of the annuity payments is:

P = P1 + P2 = 43174.34 + 61812.16 = 104986.50

This value is the present value of the annuity payments at the new interest rate of 48% per year compounded monthly.

The remaining 24 annuity payments will be made at this new rate. Therefore, the value of the last 24 annuity payments is:P/(1+0.04)24 = 45705.70

The last 24 annuity payments will have a total value of $45,705.70.

An investor acquired a property worth R$ 670,000.00 under the following conditions: down payment of 10.00% and the remainder financed in 180 equal monthly installments, with effective interest of 7.00% per year. Immediately after the payment of all the installments, that is, immediately after the payment of the last installment, he sold this property for R$ 3,500,000.00 in cash. Calculate the percentage profit or loss that occurred on this sale, that is, the percentage profit or loss that the investor had at the time of sale of the property, in relation to the investments he could have made, at his minimum attractive rate of 0.95% per month.

Answers

Profit Percentage = (R$2,977,801.51 / R$522,198.49) x 100 = 570.06%So the investor had a profit percentage of 570.06% at the time of sale of the property.

The first step to calculating the profit or loss percentage for this situation would be to find out the total cost of the property. To do this, you can use the following formula:

Total Cost = Down payment + Total amount paid in 180 monthly installments

The down payment is 10% of R$670,000.00, which is R$67,000.00.

To find the total amount paid in installments, you can use the formula for the present value of an annuity:

PV = PMT * [1 - (1 + r/n)^(-nt)] / (r/n), where PMT is the monthly payment, r is the annual interest rate, n is the number of times interest is compounded in a year, and t is the number of years.

In this case, PMT is the total amount borrowed divided by the number of months, which is (R$670,000.00 - R$67,000.00) / 180 = R$3,294.44.

Plugging in the values, we get:

PV = R$3,294.44 * [1 - (1 + 0.07/12)^(-180)] / (0.07/12) = R$455,198.49

So the total cost of the property is R$67,000.00 + R$455,198.49 = R$522,198.49.

To find the profit or loss percentage, we need to compare this total cost to the selling price of R$3,500,000.00.

The profit is the difference between the selling price and the total cost, which is R$3,500,000.00 - R$522,198.49 = R$2,977,801.51.

The percentage profit can be found using the formula:

Profit Percentage = (Profit / Cost) x 100Substituting the values, we get:

Profit Percentage = (R$2,977,801.51 / R$522,198.49) x 100 = 570.06%So the investor had a profit percentage of 570.06% at the time of sale of the property.

This is much higher than his minimum attractive rate of 0.95% per month.

Answers

Long-run aggregate supply refers to the potential output an economy can produce given its natural rate of unemployment. Aggregate demand, on the other hand, refers to the total amount of goods and services demanded in an economy at a particular price level. The simultaneous occurrence of an increase in equilibrium real GDP and an increase in the equilibrium price level could be due to a shift in aggregate demand to the right.

This shift could occur due to various factors, including an increase in government spending, a decrease in taxes, or an increase in investment. The shift in aggregate demand would cause a higher equilibrium price level and higher real GDP. An increase in real GDP but no change in the equilibrium price level could be due to a shift in the long-run aggregate supply curve to the right.

This shift could occur due to factors such as an increase in productivity or an increase in the labor force. This shift would cause a higher real GDP but no change in the price level. A decrease in equilibrium real GDP with no change in the equilibrium price level could be due to a shift in the aggregate demand curve to the left.

This shift could occur due to factors such as a decrease in consumer confidence or a decrease in government spending. The shift in aggregate demand would cause a lower real GDP but no change in the price level. A decrease in equilibrium real GDP and a decrease in the equilibrium price level could be due to a shift in the long-run aggregate supply curve to the left.

The manager of a large apartment complex knows from experience that 110 unis will be occupled if the rent is 400 dollars per month. A market survey suggests that, on the averago, one additional unit will remain vacant for each 1 dollar increase in rent. Similarly, one additional unit will be occupled for each 1 dollar decrease in rent. What rent should the managor charge to maximize revenue?

Answers

Given information: A market survey suggests that, on the average, one additional unit will remain vacant for each 1 dollar increase in rent Similarly, one additional unit will be occupied for each 1 dollar decrease in rent.

The manager of a large apartment complex knows from experience that 110 units will be occupied if the rent is 400 dollars per month. Formula for total revenue is,

[tex]Revenue = Price × Quantity[/tex]

Let's find the total quantity, if the price is [tex]$400[/tex] Per dollar increase, one additional unit will remain vacant. So, for [tex]400+x rent[/tex], [tex]400+x units[/tex] will be occupied.[tex](110 units - x vacant units)[/tex]

[tex]= 400 + x occupied units(400 + x) + (110 - x)[/tex]

[tex]= 510 units will be occupied at 400 + x rent[/tex]

Let's find the total quantity, if the price is [tex]$399[/tex] Per dollar decrease, one additional unit will be occupied. So, for [tex]399-x rent[/tex], [tex]111+x units[/tex] will be occupied. [tex](111 units + x occupied units)[/tex]

[tex]= 399 - x vacant units(399 - x) + (111 + x)[/tex]

[tex]= 510 units will be occupied at 399 - x rent[/tex]

Now, we can write down the revenue equation for two different prices: When the price is [tex]$400[/tex],

[tex]Revenue = $400 × 110[/tex]

[tex]= $44,000[/tex] When the price is [tex]$399[/tex]

[tex]Revenue = $399 × 111[/tex]

[tex]= $44,289[/tex] As we can see, if the price is [tex]$399[/tex] then the total revenue is [tex]$44,289[/tex] which is more than the total revenue obtained at [tex]$400[/tex] rent.

Hence, to maximize revenue, the manager should charge [tex]$399[/tex] rent per month.

(b) Labour markets in developing countries are often highly segmented and exhibit high levels of involuntary unemployment. Critically discuss the implications of labour market segmentation in developing countries and provide examples of policy implications. (c) Osmani (1990) proposes a theoretical model for the process of wage determination as an act of implicit cooperation amongst workers. Select any two assumptions of this model to critically discuss and assess this model's relevance to explain the features of a typical South Asian rural labour market.

Answers

a) Link between efficiency and wages:Efficiency is the output level achieved from inputs, labor being one of the inputs. The better the efficiency of the labor, the higher the wages it receives. The production function for labor is y = f (k, h), where k denotes the capital stock per worker, h denotes the hours worked per worker, and y denotes output per worker. The wage for labor is determined by the demand and supply forces in the labor market.Involuntary unemployment arises when the wages are above the equilibrium level. This situation can be explained by using a Keynesian cross diagram.

The wage rate is on the y-axis, and the labor supply and demand are on the x-axis. The intersection of labor demand and supply curves determines the equilibrium wage rate, W* (Q* is the equilibrium quantity of labor).If the wage rate is above the equilibrium level, the quantity of labor supplied will exceed the quantity of labor demanded, resulting in involuntary unemployment. The pros of this model include the provision of a framework for analyzing the labor market. The cons of this model are its assumptions, which do not reflect the real world. In addition, it does not consider the role of institutions in labor market outcomes.

b) Implications of labor market segmentation: Labor market segmentation has significant implications for developing countries, which are characterized by low productivity, poor working conditions, and low wages. In such markets, segmentation arises due to differences in skill levels, geographic location, gender, and social status. The implication of labor market segmentation is the presence of involuntary unemployment, low wages, and limited employment opportunities.

The policy implications of labor market segmentation are that policymakers need to create incentives to eliminate the barriers to entry into the labor market. They also need to promote education and training programs to enhance the skills of workers and to provide equal access to employment opportunities.

c) Osmani's model of wage determination: Osmani proposes a theoretical model for the process of wage determination as an act of implicit cooperation amongst workers. The model is based on the assumption that there is no competition among workers and that workers coordinate their wage-setting behavior. The two assumptions of this model are the implicit cooperation among workers and the absence of competition among workers.

These assumptions are not realistic, as workers do compete with each other for jobs, and cooperation among workers is not always guaranteed. In addition, the model does not account for the role of employers in wage-setting. Therefore, this model is not relevant to explaining the features of a typical South Asian rural labor market.
