A very special manufacturing operation is being designed as an assembly line. Table 1 shows the tasks that need to be performed, their task time, and preceding tasks. The goal is to produce 5760 products per month. The company has an operation pattern of 24 days per month with 8 hours per day. 1. i. Draw a precedence diagram. Determine the cycle time. Using the largest work element-time rule, assign tasks to the workstations in order to have appropriate line balancing. Identify the idle time for workstation 1, 2 and 6. ii. iii. iv. Identify the number of workstations for the balanced line. Calculate the balanced line effieciency to 2 decimal places (Example 0.78). V. vi.

A worker is currently responsible for tending two machines in a machine cluster. The service time per machine is 0.35 min and the time to walk between machines is 0.15 min.The machine automatic cycle time is 1.90 min. If the worker’s hourly rate = $12/hr andthe hourly rate for each machine = $18/hr, determine (a) the current hourly rate for thecluster, and (b) the current cost per unit of product, given that two units are produced byeach machine during each machine cycle. (c) What is the percent idle time of the worker?(d) What is the optimum number of machines that should be used in the machine cluster, ifminimum cost per unit of product is the decision criterion?
A CNC milling machine has a purchase price of £120,000 and it is considered from an accounting standpoint to be depreciated to zero value over a period of 5 years. If the machine is to be used for 2 shifts with each shift working for 37 hours/ week and 45 weeks/ year. What is the machine cost/ hr which must be charged in order to amortise/repay the costs over the 5 year period? To make the calculation simpler, you can assume that over the 5 year period you will be required to pay back 8% interest on the sum borrowed. Express your answer in § / hour rounded up to the nearest penny
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 M–N plant manufactures two different products: M and N. Selling prices and weeklymarket demands are shown in the following diagram. Each product uses raw materialswith costs as shown. The plant has three different machines: A, B, and C. Each performsdifferent tasks and can work on only one unit of material at a time.Process times for each task are shown in the diagram. Each machine is available2,400 minutes per week. There are no “Murphys” (major opportunities for the system tofoul up). Setup and transfer times are zero. Demand is constant.Operating expenses (including labor) total a constant $12,000 per week. Raw materialsare not included in weekly operating expenses.a. Where is the constraint in this plant?b. What product mix provides the highest proi t?c. What is the maximum weekly proi t this plant can earn?
A chemical firm produces sodium bisulfate in 100-pound bags. Demand for this product is 20 tonsper day. The capacity for producing the product is 50 tons per day. Setup costs $100, and storage andhandling costs are $5 per ton a year. The firm operates 200 days a year. (Note: 1 ton = 2,000 pounds.)a. How many bags per run are optimal?b. What would the average inventory be for this lot size?c. Determine the approximate length of a production run, in days.d. About how many runs per year would there be?e. How much could the company save annually if the setup cost could be reduced to $25 per run?

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,…
A company makes two kinds of door Knobs, standard and deluxe ,the making process cost the company 15$ for the standard and 20$ for the deluxe by making on a grinder and a smoother machines, which they can be run for at most 80 hours a week, each standard one needs 2 hours on the grinder, and 4 hours on the smoother, and each deluxe one needs 4 hours on the grinder and 3 hours on the smoother ,the company sales at 25$,35$ for the standard and the deluxe respectively. To have the profit it wants the company decide to make at least 15 knobs from them at a week, formulate the linear programming model?
A flow-line mass production operation consists of six manual workstations. Work units are moved synchronously and automatically between stations, with a transfer time of 10 secs. The manual processing operations performed at the six stations take 45 sec, 50 sec, 40 sec, 42 sec, 30 sec, and 55 sec, respectively. Determine (a) cycle time for the line, (b) time to process one work until through the six workstations, (c) average production rate, and (d) time to produce 20,000 units.
