Extracted text: Chapter 8. As we saw in Problem Set 2, on a Thursday, Jeanie decided that she would like to have a dinner party for a few of her colleagues and was wondering if Saturday was a feasible day to have the party or not. She wanted to get an idea of how many hours of work she would need to do to make a fancy dinner ready by 6 PM on Saturday. She decided to create a project network based on the activities she thought were essential for doing this. We had helped her to identify the critical path by creating a project network and activity schedule. Now, Jeanie realizes that she has another project that needs to be completed by Saturday and wonders if she can "outsource" some of her activities by paying someone else to do them, since she only has a total of 6 hours available now instead of her original 12 hours of availability. Her normal costs and crashing costs along with the crashing time are given in the table below. She wants to minimize her costs, so running a crashing LP model is her best option. Time Normal Crashing Crash Activity Description Immediate (hours) Cost Time Cost Predecessor Ti Ci Ti' Ci' A Choosing dishes/recipes 2 200 1.5 300 Inviting and confiırming # of people 2 200 1 300 Making ingredient list IA 100 500 Making shopping list |В, С 1 100 200 E Going for shopping 2 200 300 F Making the meal 5 500 1500 G Setting the Table IF 0.5 50 100


Extracted text: Notice that the original PERT/CPM model you created will work for this problem since the order of the activities has not changed. Create a Crashing Model and answer the following questions: 1. Jeanie's total cost of crashing is $ 2. The activities that Jeanie needs to crash are: 1. by hours 2. by hours 3. by hours 4. hours by
