Question
Chapter 9, Problem 35AP
(a)
Summary Introduction
Interpretation:The sequence for the production of the ice-cream flavors for the minimization of the mean flow time for all flavors is to be determined.
Concept Introduction:
Shortest processing time rule is used for the minimization of mean time flow of the project and hence it is used to minimize the time of mean flow of a process.
Tardiness is used to calculate the difference between the actual completion time and the required due date of the job. Any tardy jobs get completed after the due date of the job.

The company (from the previous example) producing training sets for basic operations with SMD components produces them in a total of 3 of its factories: New York factory, the Washington factory, and the HK factory.
In total, the company will produce a total of 420 teaching sets. The New York factory will produce 50% more sets than the total production in Washington and HK combined, and the production in Washington factory is 10% higher than in HK factory. How many sets are produced in the individual production factories?

In addition to homestays bookings, Miss Felicia also receives bookings for events and meals delivery during the guests’ stay. Recently, due to the lifting of the movement control order (MCO), there are increasing requests and bookings made by the guests. Miss Felicia is overwhelmed with the processes since she is using a manual system in managing all bookings and requests, which are recorded in a logbook. There were incidents of overlapping and missing bookings and payments received. On several occasions, meals were not delivered as promised. Miss Felicia is worried that these incidents could affect her business’s reputation and sales. Therefore, she is urgently considering a new system to support FNB Hospitality business. She is also interested to consider a platform or a system that could help the business…arrow_forwardA company assembles a product that consists of three pieces called AA, BB, and CC.

Each specialist has about 5 administrative employees who help with coding, billing, customer service, and other administrative tasks. You supervise all administrative employees. For two months you have noticed that a series of conflicts have arisen between the employees you supervise, which you must address promptly to avoid escalation. These are the conflicts that have been identified: A new position has been opened to supervise night operations and two of the employees have requested it. However, both have resorted to demonstrating that the other does not have the capabilities to rise to the position. These interpersonal differences have resulted in a tense work environment.It has been rumored that one of the medical specialists is going to retire, so it is possible that he will put the five administrative employees…arrow_forward
- Cubway, the sandwich shop, is run by Jim, Tim and Kim. When a customer arrives, Jim spends 5 minutes taking order from the customer. After this, Tim prepares bread and Kim prepares filling for the order. These activities are performed in parallel, and take 6 and 12 minutes respectively. Jim then assembles the bread and filling, which takes 4 minutes of his time. Finally, Tim spends 1 minutes in delivering the order and taking payment. What is maximum number of sandwiches Cubway can make per hour? (In other words, what is the capacity of the process in sandwiches per hour?)arrow_forwardThe process of making a batch of paint in a paint factory consists of the following steps: First, the correct amount of raw materials must be mixed in the proper sequence. The operator must follow specified safety instructions. After mixing, a sample is drawn and taken to a laboratory, where it is tested to ensure conformance to customer requirements a and specifications. Next, the mixing tank is taken to a filling station and verified to be the correct one prior to filling individual cans of paint. The filled cans go to the packing department where labels are printed and applied to the cans. They are inspected to ensure that the labels are correct and the proper quantity was produced for the customers’ order. The cans are packed in boxes and moved to shipping. a.

The process is experiencing severe quality problems related to insufficiently trained workers. Specifically, 20 percent of the parts going through operation 1 are badly processed by the operator. Rather than scrapping the unit, it is moved to a highly skilled rework operator, who can correct the mistake and finish up the unit completely within 15 minutes. The same problem occurs at station 2, where 10 percent of the parts are badly processed, requiring 10 minutes of rework. Station 3 also has a 10 percent ratio of badly processed parts, each of them requiring 5 minutes by the rework operator. a)What is the utilization of station 2 if work is released into the process at a rate of 5 units per hour? b)Where in the process is the bottleneck? Why? (Remember, the bottleneck is the resource with the lowest capacity, independent of demand.)arrow_forwardABC Manufacturing is evaluating the desirability of implementing process improvements and is seeking your help in determining whether it should proceed with the proposed improvements. One area of focus is how the improvements will affect processing time (manufacturing cycle time efficiency). Estimated activities and associated times for these activities under both the current process and after process improvements are as follows: Process Activity Current Process After Process Improvements Wait time 4 hours 1 hour Inspection 40 minutes 5 minutes Moving 80 minutes 20 minutes Processing (manufacturing) 2 hours 75 minutes Required: 1. Determine the manufacturing (production) lead time (in minutes) for each of the two decision alternatives. 2. Determine the manufacturing cycle efficiency (MCE) for each decision alternative.arrow_forward
