Q1:

Answer these questions with concision and precision:

A: Why integration within an enterprise information system (EIS) is needed? What makes, from EIS integration, a challenge?

B: Compare, at least, three different attempts of having an integrated enterprise system?- you have to specify how each one works and the level of integration obtained.

Q2: Assuming that the various activities that need to be performed in the manufacturing process are considered labor operations, draw a value chain level diagram that thoroughly depicts the duality relationships between pairedevents that lays behind the flow of resources in the value chain.

Q3:

BrotherBikes is relatively small but growing at a fast rate. The varied options offered either for bikes or T-shirts is attracting an increasing number of customers either big dealers or individuals.

Customers may either visit BrotherBikes 's website or showroom in order to view the latest offers of bikes and t-shirts.

When a customer decides to make a purchase or a customer submits a purchase inquiry through the website, a salesperson initiates a series of procedures to properly document the sale order and sale transaction. First, the salesperson determines the model of the selected bikes or t-shirts. Then, salesperson offers the customer a list of options. The customer may (1) purchase items off the showroom with no added features, (2) purchase items off the showroom with additional features, or (3) special order items that are not currently in the showroom.

If customers pay cash, a simple sales contract is prepared and the customer picks up the purchased items. When customers use an installment method of purchase. Before an installment purchase is authorized, the customer's credit must be verified to determine credit worthiness.

With an installment purchase, an installment agreement is prepared in addition to the sales contract. The accounts receivable clerk has arranged financing through a local bank for all installment sales. When an installment sale is made, the bank sends BrotherBikes's accounts receivable clerk a lump-sum payment equal to the price of the purchased items. Instead of making payment to the accounts receivable clerk, customers pay the bank plus interest. Once the credit is approved, the customer can take delivery of the purchased items.

1. Julia recently received a GPS navigation system. (a) To test the accuracy of the GPS, she records her velocity at various times during her commute to work, then compares this information with the GPS's distance estimate. Let v(() be Julia's velocity, in miles per hour (mi/h), at time t hours (h) after she begins driving to work. Julia records several values of v(t) in the following table. t (h) 0.06 0.11 0.16 0.21 0.26 v(t) (mi/h) 60 59 56 55 50 During Julia's drive, the car is always decelerating. i. Use a left Riemann sum with four equal subintervals to estimate the distance Julia traveled between =0.06 h and t = 0.26 h. ii. Is your estimate from part (a) an overestimate or an underestimate? ifi. Julia's GPS estimates that between ? = 0.06 h and t = 0.26 h she traveled 10.8 mi, and it says that its estimate is correct to within 0.1 mi. Could the GPS be correct? Explain. (b) The following day Julia drives to the Zahir, a hip new ski resort in Michigan's Upper Peninsula. During the exhausting 400-mile drive, she tracks her pace.! In particular, she finds that, when she has traveled d miles on the highway, her pace, in hours per mile (h/mi), can be modeled by the function P(d), which is graphed below. 1/ (h/mi) 0.03 0.02 0.01 O- -0 1 = P(d) T -d (ml) 100 200 300 400 1. How long did Julia's trip take? il, Write a mathematical equation involving the function P representing the following sentence. Your answer may involve definite integrals. It takes Julia twice as long to travel the first hundred miles as it takes for her toPAGE 1 -- Consumer Utility Assume both Good X1 and Good X2 cost 52, and Person] has a budget of $24 for the two goods. Assume, given the shape of hisfher indifference curves, Person J most prefers to consume equal units of Goods A and B. 1a. (i) Draw an indifference curve for Person J for goods X1 and X2. In your diagram place Good X2 on the yaxis and Good X1 on the xaxis, and label the indifference curve l1. (ii) Insert a budget line curve into the diagram that reflects the optimal preference of Person] with his/her cui'rent budget. On each axis, indicate the amount of X1 and X2 that Person] is consuming. 1b. (i) Return to la and draw two additional indifference curvesone below the original indifference curve and one above the original indifference curve. Assume the price of Good X1 falls to $1. Make changes to your diagram in (a) above as a result of this price change. 1c. At the new price for good X1, how many units of X1 does consumer] consume? 1d. At the new price for good X1, how many units of X2 does consumer] consume? 1e. Depict the individual demand curve of Person] for Good X1 for quantities demanded at prices 51 and 52. Show numerical values for price and quantity. Why does the Short Run Aggregate Supply curve slope upwards while in the Long-Run Aggregate Supply is perfectly inelastic. 2. Assume we start in LR equilibrium. Suppose we see the consumer confidence index rise. Use our Aggregate Supply/Aggregate Demand model to discuss the following. A. Would this event affect AD, SRAS, or LRAS? How and Why? Show this on an AD/AS graph B. Would this create an output gap? If so, what kind? Label this on your graph. C. How could the market self-correct to get back into LR equilibrium? Show this on your graph. 3. Consider a new deposit to the US banking system of $1000. Suppose that all banks have a desired reserve ratio of 20%. The following table shows how deposits, reserves, and loans enable the creation of money. Assume there is no currency drain and that banks do not hold on to excess reserves. a. Complete the table below. Round Change in Change in Change in Loans Deposits Reserves First $1000 $200 $800 Second Third Fourth Fifth b. After 5 rounds, what is the total change in deposits as a result of the single NEW deposit? C. What is the eventual total change in deposits? d. What is the eventual change in the money supply? What is the eventual change in reserves? In loans
