A toy factory is planning to make an additional item, which would be processed in 4 departments. The company is proposing to produce 600,000 units per year, working 250 days per year. The estimates of times made by an industrial engineer are in the table: DepartmentsTimes 1 2 3 4Average processing time (second/part)8 131050Average maintenance, time/day (minutes)20302015Average daily setup, time (minutes)20153020Average bookkeeping, time/day (minutes)108125Machine adjustment, time/day (minutes)15101515Defective items, (% of production)5 6 4 4The 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 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?

The analyst in the Dorben Company wishes to assign a number of like facilities to an operator based on minimizing the cost per unit of output. A detailed study of the facilities revealed the following: Loading machine standard time = 0.30 minutes Unloading machine standard time = 0.25 minutes Walk time between two machines = 0.09 minutes Operator rate = $12.00 per hour Machine rate (both idle and working) = $18.00 per hour Machine cycle time = 1.55 minutes TEC = The Expected Cost a) With your initial estimation, how many machines can be serviced exactly?(please keep a non-integer with three decimal places) b) How much is your TEC per piece if the operator has idle time? (please keep three decimal places) c)How much is your TEC per piece if the machine has idle time? (please keep three decimal places) d) How many of these machines should be assigned to each operator?(please write down a numerical number)
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. Batch size is 200 and the average nonoperation time per machine is15 hr. Determine (a) manufacturing lead time and (b) hourly production rate for operation 4.Machine 1 2 3 4 5 6Setup time (hr) 5 3 6 4 5 3Operation time (min) 3.0 3.3 8.2 3.9 4.5 2.3 a. 6(4.3+200(3.9/60)+15) = 193.8 hours 24.2 days if 8 hour shiftb. 4(60)+200(3.9)/200 =5.1 hourly production for operation 4 2. 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 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.
A firm is attempting to minimize its shipping costs. The firm has 3 factories and must supply the needs of its 3 customers without shortages. Since the firm has no storage facilities, each factory must make daily shipments to its customers. The table below shows the capacity of each factory, the amount required by each customer, and the cost of shipping from each factory to each customer. Complete the table below to show the quantity shipped from each factory to each customer. (Leave no cells blank - be certain to enter "0" wherever required.) Shipping Costs ($/unit) Factory/Capacity Customer 1 Customer 2 Customer 3 A/100 units 11 5 9 B/180 units 8 7 8 C/130 units 12 7 10 Requirement— 205 units Requirement— 68 units Requirement— 137 units What is the total cost of meeting customer requirements each day?
A drug store sells 30 bottles of antibiotics per week.Each time it orders antibiotics, there is a fixed ordering costof $10 and a cost of $10/bottle. Assume that the annualholding cost is 20% of the cost of a bottle of antibiotics, andsuppose antibiotics spoil and cannot be sold if they spendmore than one week in inventory. When the drug store placesan order, how many bottles of antibiotics should be ordered?
A factory production department consists of a large number of work cells. Each cell consists of one human worker performing electronics assembly tasks. The cells are organized into sections within the department, and one foreman supervises each section. It is desired to know how many work cells should be assigned to each foreman. The foreman’s job consists of two tasks: (1) provide each cell with a sufficient supply of parts that it can work for 4 h before it needs to be resupplied and (2) prepare production reports for each work cell. Task (1) takes 18 min on average per work cell and must be done twice per day. The foreman must schedule the resupply of parts to every cell so that no idle time occurs in any cell. Task (2) takes 9 min per work cell and must be done once per day. Neither the workers nor the foreman are allowed to work more than 8 h/day. Each day, the cells continue production from where they stopped the day before. (a) What is the maximum number of work cells that…
