WSDL and PHP exercise.The exercise is split in 2 parts:
Part 1For the Hand-in Assignment for this week, please create a Web service using PHP. This should be similar to the examples provided in the Lecture Notes (see attachment). Be sure to include the client, server and WSDL files similar to those described. Upload the server and WSDL files to a web server. Keep the Web service fairly simple, unless you are confident of creating a more complex one—don’t bite off too much. Then post the URL for your WSDL file and any other information needed to a word document.Please do this ASAP, as others in the class will be waiting for class members’ Web services in order to complete Part 2.
Part 2
For this part, write PHP scripts to access and consume two Web services that other class members have made available to you from Part 1 of the Hand-in Assignment. You can keep the scripts relatively simple if you wish, or if you are confident, you can enhance them from the simple ones provided in the Learning Resources.Submit all of the files (five at least) and specify the URLs of the services that you consumed in Part 2. This is so the Instructor can test your Web service and your consumption of others.
PS: I need part 1 solution Tuesday May 6 the latest.As you noticed, in order for you to solve part 2, I need to give you 2 web services files from the class. I am still waiting my classmates to submit the files and I will submit them as soon as I get them so that you can write the PHP scripts.
Kindly submit part1 ASAP as a reply to this thread and entire assignment will be considered to be completed as soon as both parts 1 and 2 are done.

A’s Supermarket is determined to please its customers with a customer advantage card. Currently, 30 percent of all shoppers are loyal to A’s. A loyal A’s customer shops at A’s 80 percent of the time. An unloyal A’s customer shops at A’s 10 % of the time. A typical customer spends $140 per week, and A’s is running on a 4 percent profit margin.
The customer advantage card will cost A’s an average of $0.01 per dollar spent. You believe A’s share of loyal customers will increase by an unknown amount between 2 percent and 10 percent. You also believe that the fraction of the time a loyal customer shops at A’s will increase by an unknown amount between 2 percent and 12 percent. Should A’s adopt a customer advantage card? Should A’s adopt the card if its profit margin is 8 % instead of 4 %?
Utilize a what-if table to determine your answer. Do a worksheet for base case, another worksheet for card with 4% profit margin, and another worksheet for card with 8% profit margin. Hint: Use the example in class of DVD purchasing and adoption of free maintenance policy.

You and your eight-year-old nephew Elmo decide to play a simple card game. Atthe beginning of the game, the cards are dealt face up in a long row. Each card isworth a different number of points. After all the cards are dealt, you and Elmo taketurns removing either the leftmost or rightmost card from the row, until all the cardsare gone. At each turn, you can decide which of the two cards to take. The winner ofthe game is the player that has collected the most points when the game ends.Having never taken an algorithms class, Elmo follows the obvious greedystrategy—when it’s his turn, Elmo always takes the card with the higher point value.Your task is to find a strategy that will beat Elmo whenever possible. (It might seemmean to beat up on a little kid like this, but Elmo absolutely hates it when grown-upslet him win.)(a) Prove that you should not also use the greedy strategy. That is, show that thereis a game that you can win, but only if you do not follow the same greedystrategy as Elmo.(b) Describe and analyze an algorithm to determine, given the initial sequence ofcards, the maximum number of points that you can collect playing against Elmo.(c) Five years later, Elmo has become a much stronger player.

Topic 1: Ethics and budgeting
Budgeting is generally regarded as an essential technique for planning and controlling an
organisation’s activities. However, budgeting systems can also create incentives for unethical
behaviour.
Using examples to illustrate your discussion, explain:
• How the use of budgets in planning and controlling an organisation’s activities may create
incentives for unethical behaviour; and,
• What strategies organisations can adopt to minimise the risk of their budgeting system
leading to unethical behaviours.
Topic 2: Accounting for overhead
Modern manufacturing processes are typically characterised by large-scale automation, with
machines replacing people. Consequently, manufacturing overhead has often become a much
more significant component of total manufacturing costs and this presents a particular challenge for
cost and management accountants. Competitive pressures make it essential that firms have
accurate and up-to-date cost data, but overhead is an indirect cost and allocating it to individual
products and product lines will always involve subjectivity and estimation.
Discuss the difficulties associated with allocating overhead costs in the contemporary manufacturing
environment and identify strategies that firms can adopt to help make their overhead allocations
more accurate and reliable.

QUESTION 2 Decision Analysis 20 marks

Show all calculations to support your answers. Round all probability calculations to 2 decimal places.


John Carpenter runs a timber company. John is considering an expansion to his product line by manufacturing a new product, garden sheds. He would need to construct either a large new plant to manufacture the sheds, or a small plant. He decides that it is equally likely that the market for this product would be favourable or unfavourable. Given a favourable market he expects a profit of $200,000 if he builds a large plant, or $100,000 from a small plant. An unfavourable market would lead to losses of $180,000 or $20,000 from a large or small plant respectively.

(a) 2 marks
Construct a payoff matrix for John’s problem. If John were to follow the EMV criterion, show calculations to indicate what should he do, and why?

(b) 2 marks
What is the expected value of perfect information and explain the reason for such a calculation?

John has the option of conducting a market research survey for a cost of $10,000. He has learned that of all new favourably marketed products, market surveys were positive 70% of the time but falsely predicted negative results 30% of the time. When there was actually an unfavourable market, however, 80% of surveys correctly predicted negative results while 20% of surveys incorrectly predicted positive results.

(c) 4 marks
Using the market research experience, calculate the revised probabilities of a favourable and an unfavourable market for John’s product given positive and negative survey predictions.

(d) 4 marks
Based on these revised probabilities what should John do? Support your answer with EVSI and ENGSI calculations.

(e) 8 marks
The decision making literature mostly adopts a rational approach. However, Tversky and Kahneman (T&K) (Reading 3.1) adopt a different approach, arguing that often people use other methods to make decisions, relying onheuristics.

What do they mean by the term heuristics? (2 marks)

Describethree types of heuristicsthat T&K suggest people use in judgments under uncertainty. (3 marks)

Give one example from your own experience of abiasthat might result fromeachof these heuristics. (3 marks)

QUESTION 3 Simulation 20 marks

Dr Catscan is an ophthalmologist who, in addition to prescribing glasses and contact lenses, performs laser surgery to correct myopia. This laser surgery is fairly easy and inexpensive to perform.

To inform the public about this procedure Dr Catscan advertises in the local paper and holds information sessions in her office one night a week at which she shows a videotape about the procedure and answers any questions potential patients might have.

The room where these meetings are held can seat 10 people, and reservations are required. The number of people attending each session varies from week to week. Dr Catscan cancels the meeting if 2 or fewer people have made reservations.

Using data from the previous year Dr Catscan determined that reservations follow this pattern:

Number of reservations 0 1 2 3 4 5 6 7 8 9 10
Probability 0.02 0.05 0.08 0.16 0.26 0.18 0.11 0.07 0.05 0.01 0.01

Using the data from last year Dr Catscan determined that 25% of the people who attended information sessions elected to have the surgery performed. Of those who do not, most cite the cost of the procedure ($2,000 per eye, $4,000 in total as almost everyone has both eyes done) as their major concern. The surgery is regarded as cosmetic so that the cost is not covered by Medicare or private hospital insurance funds.

Dr Catscan has now hired you as a consultant to analyse her financial returns from this surgery. In particular, she would like answers to the following questions, which you are going to answer by building an Excel model to simulate 20 weeks of the practice. Random numbers must be generated in Excel and used with the VLOOKUP command to determine the number of reservations,0 and there must be no data in the model itself. The same set of random numbers should be used for all three parts. An IF statement is required for part (a) to determine attendance each week, given cancellation of meetings.

(a) 10 marks
On average, how much revenue does Dr Catscan’s practice in laser surgery earn each week? If your simulation shows a fractional number of people electing surgery use such fractional values in determining revenue. Paste your model results into Word including a copy of formulas with row and column headings.

(b) 3 marks
Adjust your model to determine on average, how much revenue would be generated each week if Dr Catscan did not cancel sessions with 2 or fewer reservations? Paste results into Word.

(c) 3 marks
Dr Catscan believes that 35% of people attending the information sessions would have the surgery if she reduced the price to $1,500 per eye or $3,000 in total. Under this scenario how much revenue per week could Dr Catscan expect from laser surgery? Modify your Excel model to answer this and paste results into Word.

(d) 4 marks
Write a brief report with your recommendations to Dr Catscan on the most appropriate strategy.

QUESTION 4 Regression Analysis and Cost Estimation 20 marks

The CEO of Carson Company has asked you to develop a cost equation to predict monthly overhead costs in the production department. You have collected actual overhead costs for the last 12 months, together with data for three possible cost drivers, number of Indirect Workers, number of Machine Hours worked in the department and the Number of Jobs worked on in each of the last 12 months:

Overhead Costs Indirect Workers Machine Hours Number of Jobs
$2,200 30 350 1,000
4,000 35 500 1,200
3,300 50 250 900
4,400 52 450 1,000
4,200 55 380 1,500
5,400 58 490 1,100
5,600 90 510 1,900
4,300 70 380 1,400
5,300 83 350 1,600
7,500 74 490 1,650
8,000 100 560 1,850
10,000 105 770 1,250

(a) 5 marks
The CEO suggests that he has heard that the high-low method of estimating costs works fairly well and should be inexpensive to use. Write a response to this suggestion for the CEO indicating the advantages and disadvantages of this method. Include the calculation of a cost equation for this data using Machine Hours as the cost driver.

(b) 5 marks
Using Excel develop three scatter diagrams showing overhead costs against each of the three proposed independent variables. Comment on whether these scatter diagrams appear to indicate that linearity is a reasonable assumption for each.

(c) 5 marks
Using the regression module of Excel’s Add-in Data Analysis, perform 3 simple regressions by regressing overhead costs against each of the proposed independent variables. Show the output for each regression and evaluate each of the regression results, indicating which of the three is best and why.

Provide the cost equations for those regression results which are satisfactory and from them calculate the predicted overhead in a month where there were 100 Indirect Workers and 500 Machine Hours and 1,000 Jobs worked.
