Q5. Basic Tools of Process Design Consider the following six tasks that must be assigned to 4 workers on a conveyor-paced assembly line (i.e., a machine-paced line flow). Each worker must perform at least one task. Time to complete task Task 1: Task 2: Task 3: Task 4: Task 5: Task 6: 30 seconds 25 seconds 35 seconds 40 seconds 15 seconds 30 seconds The current conveyor-paced assembly line configuration assigns the workers in the following way: Worker 1: Task 1 Worker 2: Task 2 Task 3, 4 Task 5, 6 a) What is the capacity of the current line? Worker 3: Worker 4: b) Now reallocate these tasks to the same four workers to increase the capacity of the whole line, subject to the conditions that (1) a worker can only perform two adjacent operations and (2) all tasks need to be done in their numerical order. What is the capacity of this line now?

Please do whole question with all parts done correctly Farmer John sells fruit and vegetables at a farmer’s market in the middle of a city. He is bringing tomatoes to the city for this weekend’s farmer’s market. The tomatoes are very ripe and, therefore, he will need to sell the tomatoes at the farmer’s market and then have to discard any that were not sold. However, there is a cost to the farmer to bring tomatoes into the city for the farmer’s market. In particular, it costs the farmer $1.75 per case of tomatoes to prepare them and bring them to the market. Farmer John can sell each case for $4.5. Farmer John estimates that he will be able to sell 12, 13, 14, or 15 cases of tomatoes at the farmer’s market. Based on historical sales, he believes that the probabilities of being able to sell 12, 13, 14, and 15 cases are 0.1, 0.3, 0.4, and 0.2, respectively. (a) Develop a decision analysis formulation of this problem by identifying the decision alternatives, the states of nature,…

Employees Layoffs at the University Medical Center The University Medical Center is medium-sized, 300-bed capacity hospital at Dasmarinas Cavites. The facilities have grown gradually over the years and are now the 2nd largest in the town of Dasmarinas. It is entirely nonunion and has never experienced an employee layoff since its inception. Sister Veronica Cornista, the Chief Executive Officer of the hospital for 8 years presented a rather bleak financial of the BOD. This according to her is the result of the declining occupancy rate which has affected the hospital’s revenues to such an extent that it ran a deficit for the first time last 1998. Such declines have not been unusual for this industry because of increasing competition. So far, the only response to these changes has been tightening of requirements for equipment or supply purchases. The projected deficit for the coming year is around 1,300,000 unless some additional revenues were identified or some additional savings…

5. During the construction of a house, six joists of 24 ft each must be trimmed to the correct length of 23 ft. The operations for cutting a joist involve the following sequence: Operation 1. Place joist on saw horses 2. Measure correct length (23 ft) 3. Mark cutting line for circular saw 4. Trim joist to correct length 5. Stack trimmed joist in a designated area Time (seconds) 15 5 5 20 20 Three persons are involved: Two loaders must work simultaneously on operations 1,2, and 5, and one cutter handles operations 3 and 4. There are two pairs of saw horses on which untrimmed joists are placed in preparation for cutting, and each pair can hold up to three side-by-side joists. Suggest a good schedule for trimming the six joists.
