The data is for weekly sales in the dry goods department at a Wal*Mart store in the Northeast.  Peak values, I.e. spikes, usually occur at holiday periods.  Week 1 is the first week of February 2002.  To show continuity, week 1 of 2003 is represented as week 54 since week 53 represents the end of fiscal 2002 and start of the 2003 fiscal year. Dollar values are adjusted in order to disguise true sales figures, but trends in the data are retained for analysis puposes.

Dry Goods

Can you identify holiday periods or special events that cause the spikes in the data?

What holiday results in the maximum sales for this department?

a) Generate linear and quadratic models for this data.

b) What is the marginal sales for this department using each model.

c) Which model do you feel best predicts future trends and explain your rational.

Based on the model selected, what type of seasonal adjustments, if any, would be required to meet customer needs?

C# (Thank you in advance)

Create an Employee class with five fields: first name, last name, workID, yearStartedWked, and initSalary. It includes constructor(s) and properties to initialize values for all fields.

Create an interface, SalaryCalculate, class that includes two functions: first,CalcYearWorked() function, it takes one parameter (currentyear) and calculates the number of year the worker has been working. The second function, CalcCurSalary() function that calculates the current year salary.

Create a Worker classes that is derived from Employee and SalaryCalculate class.

  • In Worker class, it includes two field, nYearWked and curSalary, and constructor(s). It defines the CalcYearWorked() function using (current year – yearStartedWked) and save it in the nYearWked variable. It also defines the CalcCurSalary() function that calculates the current year salary by using initial salary with 3% yearly increment.

Create a Manager class that is derived from Worker class.

  • In Manager class, it includes one field: yearPromo and constructor(s). Itincludes a CalcCurSalary function that calculate the current year salary by overriding the base class function using initial salary with 5% yearly increment plus 10% bonus. The manager’s salary calculates in two parts. It calculates as a worker before the year promoted and as a manager after the promotion.

Write an application that reads the workers and managers information from files (“worker.txt” and “manager.txt”) and then creates the dynamic arrays of objects. Prompt the user for current year and display the workers’ and managers’ current information in separate groups: first and last name, ID, the year he/she has been working, and current salary.

Which of the following best describe Proportional Integral Derivative (PID) Control?

a) A system that changes the output of a controller based on the difference between the controlled variable and the setpoint, and how long the input has been away from the setpoint.

b)A system that changes the output of a controller based on the difference between the controlled variable and the setpoint.

c) A system that changes the output of a controller based on the difference between the controlled variable and the setpoint, and how long the input has been away from the setpoint, and how fast the input is approaching the setpoint.

d)A system that changes the output of a controller based on the difference between the controlled variable and the setpoint, and how fast the rate of change is
