The company estimates that 150 hours will be required to complete the project. The firm's three graphic designers available for assignment to this project are Lisa, a senior designer and team leader; David, a senior designer; and Sarah, a junior designer. Because Lisa has worked on several projects for Lake View Winery, management specified that Lisa must be assigned at least 40% of the total number of hours assigned to the two senior designers. To provide label designing experience for Sarah, the junior designer must be assigned at least 15% of the total project time. However, the number of hours assigned to Sarah must not exceed 25% of the total number of hours assigned to the two senior designers. Due to other project commitments, Lisa has a maximum of 50 hours available to work on this project. Hourly wage rates are $30 for Lisa, $26 for David, and $18 for Sarah.

Emily and Dave will be sent information and service lists that are geared toward helping new parents. She provided their names, address and phone numbers so that they will not miss any of the activities provided in the package. Has Cara dealt with her clients appropriately? NUYLOTNQhObm1bEVKUTO90 a0 Cara did not protect her clients' privacy when she shared their personal information with the baby registry. O Cara should not make this a regular practice.

- A company is setting up an assembly line to produce 90 units per hour. The table below identifies the work elements, times, and immediate predecessors. Work Element Time (Sec.) Immediate Predecessor(s) A 25 - B 18 A C 20 A D 5 B, C E 12 C F 8 E G 16 D, F H 12 G Use one of the heuristic decision rules described in Table below to balance the assembly line so that it will produce 90 units per hour. Clearly state the decision rule you use and complete the below table using the selected rule. Decision Rule Logic Longest work element Picking the candidate with the longest time to complete is an effort to fit in the most difficult elements first, leaving the ones with short times to “fill out” the station. Shortest work element This rule is the opposite of the longest work element rule because it gives preference in workstation assignments to those work elements that are quicker. It can be tried…Exercise 6: The Good Furniture makes two products: tah les and chairs, which mustbe processed through assemb ly and finishing dep artments. Assemb ly dep artment is availah le for 60 hours in every production period, while the finishing dep artment is availab le for 48 hours ofwork. Manufacturing one tab le req uires 4 hours in the assemb ly and 2 hours in the finishing, Each chair requires 2 hours in the assemb ly and 4 hours in the finishing, One tab le contrib utes P80 to the profit, while a chair contrib utes P60. The prob lem is to determine the numb er of tab les and chairs to makeper productionperiod, in order to maximize the profit. Exercise 7: A small generator b urns two types of fuel: bw sulfur and high sulfur to produce electricity. For one hour, each galon of bw sulfur emits.3 units of sulfur dioxide, generates 4 kilowatts electricity and costs P60.

Production Schedule is a Mess Henry Gantt greatly contributed to the classical management system method. He created none other than: The Gantt chart, and also, the task and bonus system- still used to this day. The task and bonus plan which rewarded workers for faster work by paying them higher wages to get the job done before the standard time, and their pay was docked if it took them longer to complete the task than standard. The Gantt chart ensured companies and organizations with understanding of basic structure and priority of events. I believe in problem number two, Gantt could contribute his methods that he created and fix the production schedule with a simple Gantt chart for the employees to follow, as the production schedule is a mess. It is not clear which projects should be completed first to ensure products are being delivered to customers on time. With this issue fixed, the deliveries would be on time, motivation would rise, and productivity would follow suit. When…
