Q4: The Dynaco Manufacturing Company produces a particular product in an assembly line operation. One of the machines on the line is a drill press that has a single assembly line feeding into it. A partially completed unit arrives at the press to be worked on every 7.5 minutes, on average. The machine operator can process an average of 10 parts per hour. a: Determine the average number of parts waiting to be worked on, b: the percentage of time the operator is working, and c: the percentage of time the machine is idle. 1 d: The management of Dynaco Manufacturing Company likes to have its operators working 90% of the time. What must the assembly line arrival rate be for the operators to be as busy as management would like?

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).
A machine makes two components; call them types A and B. It takes 250 seconds to switch production between the component types. During that time, no production occurs. When in production, each unit of A or B requires 0.5 second to be completed. The two components, A and B, are combined in an assembly process to make a final product; call it C. The assembly step can combine the two components into 1 unit every 2 seconds, or 30 units per minute. Assume there is ample demand. Suppose the machine rotates between one batch of 1,000 units of A and 1,000 units of B. What is the average inventory of B components? answer:______units

In a casting machining company, it takes an operator 15 seconds to load and 15 seconds to unload each machining center. There are several same centers, all working on the same type of part, and the duration of the automatic operation is 1 minute. Given that the cost per hour of the operator and the cost per hour of the machine is $10, using the man-machine diagram, determine the value of the highest production rate for the system.
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) Consider an AS/RS machine in an aisle that is 280 ft long and 70 ft high. The I/O point is in the lower left corner, and the S/R machine travels at 300 ft/min horizontally and 100 ft/min vertically. The time required to pick up or drop off a load is 0.8 minutes. Assuming a single command operation, find the total cycle time in minutes and the throughput in operations per hour. b) Complete part a, assuming dual command operation.
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.
