Jeff was just hired by GSI, Inc. to be their Environmental and Safety Coordinator. This is Jeff's first position after completing his engineering degree. He had taken a course in safety engineering as part of his studies and felt confident that he could handle the job. Management at GSI, Inc. has assured him that they are committed to maintaining a safe workplace. They have never had an individual dedicated to this task full-time. They will implement his recommendations if he can justify them. As Jeff begins to get familiar with the operations, he spends considerable time on the production floor. He notices workers clean their tools before break with a liquid from an unmarked 55-gallon drum. They also use this liquid to clean residue from their skin. They use paper towels to dry their tools and hands, throw these towels in the trash, and head to the break room for a snack and/or smoke. In talking with the workers, Jeff learns of some of their concerns. Several people mention…

Good morning interns, This is Ms. Gorman from the sales department. We have just secured a new, multi-million-dollar account! We are so good here in the sales department of Heavy-Duty Box Inc. The manufacturing director, Mr. Tsosie, has instructed me to send this problem out to all of you as this will be a deciding factor in which of you get offered the full-time positions available at the end of the internship! Our new client, Beastie Bearings Inc., needs the heaviest duty box we make here at Heavy-Duty Box for their bearings. The following email from Ms. Venegas from Beastie Bearings provides the information you will need. Remember, our mark-up sales price is 150% of what it costs us to manufacture the product. The cheaper it is for us to produce the box, the lower the cost for our client. There is also a grading rubric attached that Mr. Tsosie will be utilizing in evaluating your work. I would advise you to follow it well if you want a position! Good luck interns, Ms. Frances…

Ok this is the first problem i already answered Chapter 3. 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 reasonably 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. Help her identify the critical path by creating a project network and activity schedule (show work in your submission file in the last question of this problem set) and answer the following questions. Immediate Time Activity Description Predecessor Hours A Choosing dishes/recipes -- 2 B Inviting and confirming # of people -- 2 C Making ingredient list A 1 D Making shopping list B, C 1 E Going for shopping D 2 F Making the meal E…
