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?

A clothing factory can make three shoe types: A,B, and C. Their profits per shoe are, respectively,
$5, $4, and $3. Type A shoes require 4 pieces of leather, and 1 piece of cloth; type B shoes require
3 pieces of leather, and 2 pieces of cloth; type C shoes require 5 pieces of cloth. The factory
has 10,000 pieces of leather and 50,000 pieces of cloth available. Furthermore, the factory must
produce at least 500 units of each type of shoe.

- B: Iraq Glass Industries Company produces two types of products, A and B, each one goes through two production stages. Product A needs 1 working hour in the first phase, and 4 working hours in the second phase, while Product B needs 2 working hours in the first phase, and 3 hours of work in the second stage. If you know that the profit per unit of product A is $60, and the profit per unit of product B is $50. The available weekly working hours in the first stage are 40 hours, and in the second stage are 120 hours. Required: Building a mathematical model that maximizes the company's profitsarrow_forwardthe final answer is 0.5 A production machine operates in a semi-automatic cycle but a worker must attend the machine 100% of the time to load parts. Unloading is accomplished automatically. The worker's cost rate = 37$/hr including applicable labor overhead rate. To produce the parts, the production machine was bought six years ago for installed price of $750,000. At that time it was anticipated that the machine would last 8 years and be used 5000 hours per year. However, it is now in need of major repairs that will cost $166,500. These repairs will be made and as a result, the machine will last three years, operating 4000 hours per year. Applicable overhead rate for the machine = 42%. Cost of the starting parts = 0.12$/pc. The job runs several months so the effect of setup can be ignored. Each cycle, the actual process time = 26s, and time to load the part = 18 s. Automatic unloading takes 4 s. A proposal has been made to install an automatic parts-loading device on the machine. The…arrow_forwardSuppose that a company needs 1,600,000 items during a year and that preparation for each production run costs $500. Suppose also that it costs $23 to produce each item and $4 per year to store an item. Use the inventory cost model to find the number of items in each production run so that the total costs of production and storage are minimized.arrow_forward

If the hourly rate for workers is $50.00/h, will the assembly line be justified using a 3-year service life? Assume 50 weeks/yr.

They spend 15 minutes at the start of each day discussing the productions schedule, quality, and other administrative matters and workers take two 15-minute breaks during the day. The company experiences 81 hours of breakdowns, 72 hours of setup, 65 hours of idling, 11 hours of stoppages, spends 20 hours on rework, and spends 23 hours making defects.

- 4) A factory manufactures chairs, tables and bookcases each requiring the use of three operations: Cutting, Assembly, and Finishing. The first operation can be used at most 600 hours; the second at most 500 hours; and the third at most 300 hours. A chair requires 1 hour of cutting, 1 hour of assembly, and 1 hour of finishing; a table needs 1 hour of cutting, 2 hours of assembly, and 1 hour of finishing; and a bookcase requires 3 hours of cutting, 1 hour of assembly, and 1 hour of finishing. If the profit is $20 per unit for a chair, $30 for a table, and $25 for a bookcase, how many units of each should be manufactured to maximize profit?arrow_forwardA manufacturer has the following data regarding a product: Fixed cost per month = Rs. 50000 Variable cost per unit = Rs. 200 Selling price Per unit = Rs. 300 Production capacity = 1500 units per month If the production is carried out at 80% of the rated capacity, then the monthly profit (in Rs.) isarrow_forwardThe from-to chart below indicates the number of loads moved per 8-hr day (above the slash) and the distances in ft (below the slash) between departments in a particular factory. Fork lift trucks are used to transport the materials. They move at an average speed = 275 ft>min (loaded) and 350 ft/min (empty). Load handling time (loading plus unloading) per delivery is 1.5 min and anticipated traffic factor = 0.9. Availability = 95% and worker efficiency = 110%. Determine the number of trucks required under each of the following assumptions: (a) the trucks never travel empty; and (b) the trucks travel empty a distance equal to their loaded distance.arrow_forward

There exists unlimited demand unless stated otherwise.

Each day, the line was operating for 12 hours. The summary of the observations is shown in Table 1. Currently the average monthly salary is RM 1800 per worker. The normal operation period is 22 days per month. Analyse the given information and propose appropriate standard time for the product by applying the industrial engineering approach. Then use the standard time to compute the labour cost (in RM per unit) for the overall production process.
