Challenge yourself.
Planning an innovative house. A local electric company wants to build an experimental house that will conserve energy. Company officials believe the project breaks down naturally into the following tasks (the time required for each task is given in parentheses):
1. Draw plans for house (2 months)
2. Design energy systems for house (6 months)
3. Develop new insulation techniques (3 months)
4. Purchase land (4 months)
5. Build conventional shell of house (6 months)
6. Install new energy systems (2 months)
7. Install new insulation (1 month)
8. Finish the remaining conventional parts of the house (3 months)
9. Landscape (1 month)
10. Perform tests to determine energy usage in house (8 months)
Determine a reasonable list of dependencies for these tasks, then draw a PERT diagram and develop a schedule for these tasks. Answers will vary.

Parent W requires one of component B and two of component C. Both B and Care run on work center 10. Setup time for B is 2 hours, and run time is 0.1 hour perpiece. For component C, setup time is 2 hours, and run time is 0.15 hour per piece. Ifthe rated capacity of the work center is 80 hours, how many Ws should be producedin a week?
The Lawson Fabric Mill Produces five different fabrics. Each fabric can be woven on one or more of the mill’s 36 looms. The sales department’s forecast of demand for the next month is shown in below Table 1, along with data on the selling price per yard, variable cost per yard, and purchase price per yard. The mill operates 24 hours a day and is scheduled for 30 days during the coming month. The mill has two types of looms: draw and regular. The draw looms are more versatile and can be used for all five fabrics. The regular looms can produce only three of the fabrics. The mill has a total of 36 looms: 8 are draw and 28 are regular. The rate of production for each fabric on each type of loom is given in below Table 2. The time required to change over from producing one fabric to another is negligible and does not have to be considered.
The Lawson Fabric Mill satisfies all demand with either its own fabric or fabric purchased from another mill. Fabrics that cannot be woven at the…
in the early 1970s there were approximately 40,000 trees lining the streets of Newton. Today, that number is about 26,000-a 35% loss. The current annual rate of decline is about 650 trees per year. At this rate, if unchecked, public street trees would diminish to approximately 10,000 within a generation (25 years), and in 40 years, public street trees would no longer be part of the Newton landscape.
a) show work for how that loss comes to be 35%
b) show work for how it comes to be a decline of 650 trees per year

- Solar energy generation along highways. The potential of using solar panels constructed above national highways to generate energy was explored in the International Journal of Energy and Environmental Engineering (December 2013). Two-layer solar panels (with 1 meter separating the panels) were constructed above sections of both east-west and north-south highways in India. The amount of (kilowatt-hours) supplied to the country's grid by the solar panels above the two types of highways was determined each month. The data for several randomly selected months are provided in the table. The researchers concluded that the "two-layer solar panel energy generation is more viable for the north-south oriented highways as compared to east- west oriented roadways." Compare the mean solar energy amounts generated for the two types of highways using a 95% confidence interval. Does the interval support the re- energy searchers' conclusion?
