SITUATION: A company is about to begin
production of a new product. The manager of
the department that will produce one of the
components for the product wants to know
how often the machine used to produce the
item will be available for other work. The
machine will produce the item at a rate of
200 units a day. Eighty units will be used daily
in assembling the final product. Assembly will
take place five days a week, 50 weeks a year.
The manager estimates that it will take almost
a full day to get the machine ready for a
production run, at the cost of $300. Inventory
holding costs will be $10 a year.
QUESTION: Suppose the manager decides to
increase the run size of the new product. How
many additional units would be needed just
to accommodate the other job? How much
will that increase the total annual cost?

PROBLEM: Unable to meet the production quota resulting to opportunity loss
CAUSES: High Rate of absenteeism (Laziness of workers)
Idle Time of Workers (Laziness)
Shortage of Materials
Due to under-stock (supplier’s problem)
Insufficient Number of Trucks (supplier’s problem)
Longer Machine Downtime
Lack of Technician (Machine cause)
Bottleneck
Poor Layout
DATA:
The company operates 9 hours a day with one hour organized lunch break
Total working days per month is 20 days
Production Quota is 40,000 units per day
Actual Output is 16,000 units per day
Rate of absenteeism is 8 workers per day
Machine Capacity is 4000 units per…

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…arrow_forwardManufacturing Company uses FIFO method of accumulating costs in a two-department process.

How many ma-chines should be purchased to meet the upcoming year’s de-mand without resorting to any short-term capacity solutions?arrow_forwardTheories and concepts: Cause of the difficulties In this section, I will explain the causes of the difficulties which I have explained above. The reason for the missing cages uses to be that the cage is still being picked or not and if the picker is still using the cage to pick the items then request the picker to drop the cage off to the packing department so that the items can be packed and sent out the shipping department for the delivery. Also, if the cage is not in the picking department buffer or pack buffer and is not being picked then as a process guide it was my duty to search for the cage at the packing stations first, and if not found then to escalate to the management so that relevant department can be contacted for the action. During the critical pool time, there were a few shipments IDs use to get sent down from the picking department which they couldn’t send into the picker’s scanners as either the batch assigned for the item by the stowing department would be wrong or…arrow_forwardWhich operation is the bottleneck of this process? a.
