Chapter 7, Problem 26P
The Wet Wellies Corporation produces waterproof boots and assembles them with optional linings and other features on an assembly line. Due to global warming, the demand for wellies has increased and the company would like to be able to produce 1200 boots in an 8-hour day. The table below contains work elements involved in the production process, as well as time and precedence requirements.
- a. Calculate the desired cycle time for boot production.
- b. Calculate the theoretical minimum number of workstations.
- c. Draw a precedence diagram and balance the line.
- d. Calculate the efficiency of the line.
- e. Customer feedback and returns indicate there are problems with the outer sole of the boot. The QIT (quality improvement team) recommends either taking more time prepping the outer sole or taking more time assembling the outer sole to the boot. They estimate increasing the time of either work element I or J by 0.1 minutes would help fix the issue. Does it matter which work element time is increased? Why or why not?

Scenario
You have been given a task to create a demand forecast for the second year of sales of a premium outdoor grill.
Accurate forecasts are important for many reasons, including for the company to ensure they have the materials
they need to create the products required in a certain period of time. Your objective is to minimize the forecast
error, which will be measured using the Mean Absolute Percentage Error (MAPE) with a goal of being below 25%.
You have historical monthly sales data for the past year and access to software that provides forecasts based on
five different forecasting techniques (Naïve, 3-Month Moving Average, Exponential Smoothing for .2, Exponential
Smooth for .5, and Seasonal) to help determine the best forecast for that particular month. Based on the given
data, you will identify trends and patterns to create a more accurate forecast.
Approach

Approach
Consider the previous month's forecast to identify which technique is most effective. Use that to forecast the next
month.
Remember to select the forecasting technique that produces the forecast error nearest to zero. For example:
a. Naïve Forecast is 230 and the Forecast Error is -15.
b. 3-Month Moving Forecast is 290 and the Forecast Error is -75.
c. Exponential Smoothing Forecast for .2 is 308 and the Forecast Error is -93.
d. Exponential Smoothing Forecast for .5 is 279 and the Forecast Error is -64.
e. Seasonal Forecast is 297 and the Forecast Error is -82.
The forecast for the next month would be 230 as the Naïve Forecast had the Forecast Error closest to zero with a
-15. This forecasting technique was the best performing technique for that month. You do not need to do any
external analysis-the forecast error for each strategy is already calculated for you in the tables below.
