A company uses various machines in the preparation of ice cream. The firm has been successful until recently when it noticed growing repair expenses for the various machines it uses. Over the past 20 months, the machines have broken down at the rate indicated in the following table: Each time a machine breaksdown, the company estimates that it loses an average of US$300 in production time and service expenses. Should the company opt to purchase a service contract for preventive maintenance by Angeles Machineries Inc., (AMI) there will still be breakdowns, averaging one breakdown per month. The price for this service by AMI is US$150 per month. a. If the company continues as is, what is the expected no. of breakdowns based on past history? b. What will be the cost of breakdowns per month to the company without a preventive maintenance contract? c. What will be the cost of breakdowns per month to the company with a preventive maintenance contract? d. Should they engage the…
An emergency situation has arisen in the milling department, because the ship carrying a certain quantity of a required part from an overseas supplier sank on Friday evening. A certain number of machines in the department must therefore be dedicated to the production of this part during the next week. A total of 1000 of these parts must be produced, and the production cycle time per part = 16.0 min. Each milling machine used for this rush job must first be set up, which takes 5.0 hr. A scrap rate of 2% can be expected. Assume availability = 100%. (a)If the production week consists of 10 shifts at 8.0 hr/shift, how many machines will be required? (b)It so happens that only two milling machines can be spared for this emergency job, due to other priority jobs in the department. To cope with the emergency situation, plant management has authorized a three-shift operation for six days next week. Can the 1000 replacement parts be completed within these constraints?
1. A certain batch of parts is routed through six machines in a batch production plant. The setup and operation times for each machine are given in the table below.

Suppose the part in the previous problem is made in very large quantities on a production line in which an automated work handling system is used to transfer parts between machines. Transfer time between stations is 30 sec. total time required to setup the entire line is 102 hr. Assume that the operation times at the individual machines remain the same as in the previous problem, Determine (a) manufacturing lead time for a part coming off the line,…
Consider a line consisting of only one machine. This machine takes on average 4 minutes (te=4 min) to complete a job and Ca2=Ce2=1. The arrival rate of the parts to this machine is 1/8 part/minutes.

A batch of 35 parts is ordered by a customer about every six months. The parts are currently processed sequentially through five conventional machines, listed in the following table with setup times and work cycle times per piece. These machines all require an operator to be in attendance during the work cycle. There is a delay of 10 hr/machine dueto transport between machines and waiting in queues of other parts processed by thesemachines. A recommendation has been made to process the parts on a new multitaskingmachine that would complete the batch in one setup, which would involve a simple fixtureand a setup time of 2.0 hr. The work cycle on the multitasking machine consists of thesame operations that are accomplished by the five machines, but the cycle time would beless than the sum of the five cycle times by one-half because of tool path improvementsand reduced part handling. Determine the manufacturing lead time (how long it takes tocomplete the batch of 35 parts, including…
