The parts are produced within the departments in a sequential manner (from department 1 to 2 to 3 to 4).
Determine the efficiency of each departmental operation if only one shift is operated between 7:30 am-4:30 pm, with a 40 minute lunchbreak and two 10 minute coffee breaks.
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…
: The output of a certain machine can be increased if it undergoes a major overhaul now and it will
result additional cash flow of $ 20,000 at the end of each year for “N” years. If i = 15 % per year,
how much can we afford to invest to overhaul this machine?

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.arrow_forwardB: Iraq Glass Industries Company produces two types of products, A and B, each one goes through two production stages.

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_forward
- A proposal has been submitted to replace a group of assembly workers, each working individually, with an assembly line. The following table gives the individual work elements. Element Te (min) Immediate predecessors 1 1.0 2 0.5 3 0.8 1,2 4 0.3 5 1.2 3 0.2 3,4 7 0.5 4 8 1.5 5,6,7 The demand rate for this job is 1600 units/week (assume 40 h/week) and the current number of operators required to meet this demand is eight using the individual manual workers. a) Construct the precedence diagram from the data provided on work elements. b) Use the (i) Kilbridge and Wester rule and (ii) ranked positional weights method to assign work elements to stations, respectively. c) What is the balance delay for the solutions? d) The initial cost to install the assembly line is $2,000,000. If the hourly rate for workers is $50.00/h, will the assembly line be justified using a 3-year service life? Assume 50 weeks/yr. Use a rate of return of 10%. 2.arrow_forwardthe final answer is 0.5 A production machine operates in a semi-automatic cycle but a worker must attend the machine 100% of the time to load parts. Unloading is accomplished automatically. The worker's cost rate = 37$/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.

- Consider the following tasks that must be assigned to four workers on a conveyor-paced assembly line (i.e., a machine-paced line flow). Each worker must perform at least one task. There exists unlimited demand unless stated otherwise.
