1) Construct a network diagram for the activities 2) Determine the critical path for the network using the ES/EF/LS/LF algorithm. Are there several critical paths? What is the length of the “project”...
ії A family has decided to remodel their kitchen. They will be doing so without the help of an interior designer, though they will be having contractors do all the work. The project will involve replacing the cabinets, the floors, and the countertop, as well as painting the walls. No new appliances will be purchased. Before the work can be begun, the family must measure the kitchen, decide on a layout, and find a budget. These activities take 0.5 days, 2 weeks, and 1 week, respectively. The family already knows which vendor they wish to purchase cabinets from, but they must still find the general contractor, as well as the stores from which they will purchase the floors and the countertop. Finding the contractor takes 1 week, while the other 2 activities take 2 weeks each. Once the stores have been selected, it takes 2 days and 3 days, respectively, to pick the flooring and countertop. Choosing cabinets is slightly more involved and will take a total of a week. Once the cabinets have been purchased, they will be manufactured and delivered in 3 weeks. Packing up the existing kitchen takes 2 (very intense) days, while demolition of the kitchen takes an additional 3 days. Installation of the new cabinets takes 1.5 weeks (including trim and detail work). Once the cabinets are installed, the countertops can be installed, which will take 1 day. After this is complete, walls can be painted, which takes 2 days. Finally, the flooring can be installed, taking another 2 days. Unpacking everything into the kitchen takes 2 days.
