Table 3 shows the process sequence in a production line and its related direct time study data. The production process must follow a specific route of processes A, B, C, and D respectively. Task A is in full automatic mode and requires one operator at the workstation. The worker at task B was rated with 90%, the worker at task C was rated with 115% and the worker at task D was rated with 80%. The standard allowances accepted by the company are 6% for fatigue, 5% for personal, and 4% for delay. The normal operating period is 8 hours per day and 24 days per month. Analyse the given information and determine the standard time for the product in minutes.

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)
A certain job shop specializes in one-of-a-kind orders dealing with parts of medium-to-high complexity. A typical part is processed sequentially through 10 machines in batch sizes of 1. The shop contains a total of eight conventional machine tools and operates 40 hr/wk of pro duction time. Average time values on each part per machine are: machining time = 0.5 hr, work handling time = 0.3 hr, tool change time = 0.2 hr, setup time = 3 hr, and non operation time = 12 hr. A new programmable machine is being considered that can per form all 10 operations in a single setup. The programming of the machine for this part will require 20 hr; however, the programming can be done off-line, without tying up the machine. Setup time will be just 2 hr because simpler fixtures will be used. Total machining time will be reduced to 80% of its previous value due to advanced tool control algorithms; work han dling time will be the same as for one machine; and total tool change time will be reduced by…

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. 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. Identify the number of workstations for the balanced line. Calculate the balanced line effieciency to 2 decimal places (Example 0.78).
It is currently day 10 in the production calendar of the Machine Shop. Three orders(A, B, and C) are to be processed at a particular machine tool. The orders arrived in thesequence A-B-C. The table below indicates the process time remaining and productioncalendar due date for each order. Determine the sequence of the orders that would bescheduled using the following priority control rules: (a) first-come-first-serve, (b) earliest due date, (c) shortest processing time, (d) least slack time, and (e) critical ratio

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…
A batch of 35 parts is ordered by a customer about every six months. The parts are currently processed sequentially through five conventional machines, listed in the following table with setup times and work cycle times per piece. These machines all require an operator to be in attendance during the work cycle. There is a delay of 10 hr/machine dueto transport between machines and waiting in queues of other parts processed by thesemachines. A recommendation has been made to process the parts on a new multitaskingmachine that would complete the batch in one setup, which would involve a simple fixtureand a setup time of 2.0 hr. The work cycle on the multitasking machine consists of thesame operations that are accomplished by the five machines, but the cycle time would beless than the sum of the five cycle times by one-half because of tool path improvementsand reduced part handling. Determine the manufacturing lead time (how long it takes tocomplete the batch of 35 parts, including…
Suppose that four machines, 1, 2, 3, and 4 have been identified as belonging in a Group Technology (GT) machine cell. 50 parts enter the machine grouping at machine 3, 20 parts leave afterprocessing at machine 1, and 30 parts leave after machine 4. Determine a logical machine arrangement through cluster analysis.
