Coding Java Vending machine Lab
Given two integers as user inputs that represent the number of drinks to buy and the number of bottles to restock, create a VendingMachine object that performs the following operations:
Purchases input number of drinks
Restocks input number of bottles
Reports inventory
The VendingMachine is found in VendingMachine.java. A VendingMachine's initial inventory is 20 drinks.
Ex: If the input is:
5 2
the output is:
Inventory: 17 bottles

a) The forecasted demand for the week of October 12 using a 3-week moving average =pints (round your response to two decimal places).
b) Using a 3 -week weighted moving average, with weights of 0.20,0.30, and 0.50, using 0.50 for the most recent week, the forecasted demand for the week of October 12=_______ pints (round your response to two decimal places and remember to use the weights in appropriate order - the largest weight applies to most recent period and smallest weight applies to oldest period.)
c) If the forecasted demand for the week of August 31 is 350 and α = 0.25, using exponential smoothing, develop the forecast for each of the weeks with the known demand and the forecast for the week of October 12 (round your responses to two decimal places).

A toy manufacturer makes its own wind-up motors, which are then put into its toys While the toy manufacturing process is continuous
A toy manufacturer makes its own wind-up motors, which are then put into its toys While the toy manufacturing process is continuous, the motors are intermittent flow. Data on the manufacture of the motors appears below.
Annual demand (D)-50,000 units Daily subassembly production rate = 1,000
Setup cost (S) = $85 per batch Daily subassembly usage rate = 200
Carrying cost = $.20 per unit per year
1. To minimize cost, how large should each batch of subassemblies be?
2. What is the average inventory for this problem?
3. What is the total annual inventory cost (holding plus setup) of the optimal behavior in this 3 Marks problem?

To determine whether the pipe welds in a nuclear power plant meet specifications a random sample of welds is selected
To determine whether the pipe welds in a nuclear power plant meet specifications a random sample of welds is selected, and tests conducted on each. Weld strength is measured as the force required to break the weld. Suppose the specifications state that mean strength of welds should exceed 100lb/in2; the inspection team decides to test Ho : μ = 100 versus Ha : μ < 100 why is this not as good as Ha : μ > 100

Patients are arriving at a clinic at a rate of two per minute. Each patient’s visit consists of four steps: check in, record vital signs, receive treatment, and check out. A receptionist takes 1 minute to check a patient in. A nurse takes 2 minutes to record the patient’s vital signs. A doctor spends 10 minutes with a patient. A staff member takes 3 minutes to check a patient out. What is the cycle time of the process in minutes?
