1. A product line has two models: X and Y. Model X consists of 4 components: a, b, c, and d. The number of processing operations required to produce these four components are 2, 3, 4, and 5, respectively. Model Y consists of 3 components: e, f, and g. The number of processing operations required to produce these three components are, 6, 7, and 8 respectively. The annual quantity of Model X is 1000 units and of Model Y is 1500 units. Determine the total number of (a) components and (b) processing operations associated with these two models, (c) workers that will be needed to accomplish the processing operations if each worker works 800 hr/yr. Solution: (a) The total number of components: npf = PQnp 1000(4) + 1500(3) = 4000 + 4500 = 8500 components …show more content…
Total work content for a product assembled on a manual production line is 33.0 min. Production rate of the line must be 47 units/hr. Base parts are attached to a moving conveyor whose speed = 2.2 m/min. Repositioning time per worker is 6 sec, and line efficiency is 94%. Due to imperfect line balancing, the number of workers needed on the line must be two more workers than the number required for perfect balance. Manning level = 1.6, excluding utility workers. Determine (a) the number of workers and (b) the number of workstations on the line. (c) What is the balance efficiency for this line? (d) If the workstations are arranged in a line, and the length of each station is 3.3 m, what is the tolerance time in each station? (e) What is the elapsed time a work unit spends on the line? Solution: (a) Tc = 60(0.94)47= 1.2 min, Ts = 1.2 - 0.1 = 1.1 min For perfect balance, Eb = 1.0. w = Minimum Integer ≥ 33.0 1.0(1.1)= 30 workers. With 4 more workers than required for perfect balance, w = 30 + 2 = 32 workers (b) n = 32 1.6 w M = 20 stations (c) Eb = 33.0 32(1.1)= 0.9375 = 93.75% (d) Tt = Ls/vc = (3.3 m)/(2.2 m/min) = 1.5 …show more content…
A ten-station rotary-indexing machine performs machining operations at nine workstations, and the tenth station is used for unloading and loading parts. The longest process time on the line is 1.75 min and the loading/unloading operation requires less time than this. It takes 9.0 sec to index the machine between workstations. Stations break down with a frequency of 0.006, which is considered equal for all ten stations. When breakdowns occur, it takes an average of 8.0 min to diagnose the problem and make repairs. The starting work part costs $2.50 per unit. Operating cost of the indexing machine is $96/hr, and tooling cost is $0.38 per piece. Determine (a) line efficiency, (b) average hourly production rate, and (c) completed part cost. Solution: (a) F = np = 10(0.006) = 0.06 Tc = 1.75 + 9/60 = 1.90 min Tp = 1.90 + 0.06(8) = 1.90 + 0.48 = 2.38 min/pc E = 1.90/2.38 = 0.798 = 79.8% (b) Rp = 60/2.38 = 25.2
The spaghetti diagram data complements the findings of the work sampling. In general, fabrication operators travel more than operators in other departments. This generalization is a result of several factors such as, the machines they need to use are not all located within their department, they have to collect their material off the racks, and the wash area is not easily accessible. However, based on the spaghetti diagram of each operator, it can be seen that there is one operator in the fabrication area that travels the most distance during his daily tasks. For this reason, it would be beneficial to move that operator from their current work are to the location that is closer to the fabrication area with the rest of the operators. This would reduce the travel distance to the inventory racks, tools, and the wash area. Additionally, it would also be ideal to move some machines closer to the fabrication operators, however, some machines are constrained by their wall hookups or the cost that would be incurred to move
b. The amount of molasses and byproduct shipped to seven customers (a majority of which are internal and therefore don't generate profit accounted for in this model).
By end of 1990, They employed 8,486 FT employees and 134 PT employees. By February 2014, they had 44,430 FT employees and 1,321 PT employees.
The presentation of the material is in dollars only. Overhead is applied to products as a percent of direct labor dollar cost. Factory profit for each year is found by subtracting direct material, direct labor, and direct overhead costs from total sales. The overhead percentage is calculated at the same time budgeting and is applied as a single overhead pool throughout each model year. The consulting company used 435% of direct labor costs in 1987 for their study; the budgeted was actually 437% (OH/DL=107,954/24,682). A similar percentage applies in the following year (109890/25294=434.5%). However in the next two years, after the outsourcing of oil pans and mufflers was enacted, the allocation of overhead in...
Results: The experiments required the starting, ending, and total times of each run number. To keep the units for time similar, seconds were used. An example of how to convert minutes to seconds is: 2 "minutes" x "60 seconds" /"1 minute" ="120" "seconds" (+ number of seconds past the minute mark)
The sales director proposed that if the firm were to reduce the price of Item 345 to FF15.00/m, they would be able to increase sales to 175,000 units (or 25% of industry volume). But if they were to keep the price at the current value of FF20.00/m, they would be able to sell not less than 75,000 units (or 11% of industry volume).
The Darby Company is re-evaluating its current production and distribution system in order to determine whether it is cost-effective or if a different approach should be considered. The company produces meters that measure the consumption of electrical power. Currently, they produce these meters are two locations – El Paso, Texas and San Bernardino, California. The San Bernardino plant is newer, and therefore the technology is more effective, meaning that their cost per unit is $10.00, while the El Paso plant produces at $10.50. However, the El Paso plant has a higher capacity at 30,000 to San Bernardino’s 20,000. Once manufactured, the meters are sent to one of three distribution centers – Ft. Worth, Texas, Santa Fe, New Mexico and Las Vegas. Due to the proximity of El Paso to Ft. Worth, they are only plant to ship to Ft. Worth. The costs associated with each shipment are described in detail in Appendix 2.2A. From these distribution centers, meters are shipped to one of nine customer zones. The Ft. Worth center services Dallas, San Antonio, Wichita and Kansas City, the Santa Fe center services Denver, Salt Lake City, and Phoenix, and the Las Vegas center ships to Los Angeles and San Diego.
Will you state the hours of labor at the period when you first went to the factory, in ordinary times?
Overhead based on direct labor includes the cost of the Product Development Support Center, interest expenses, and general and administrative expenses. The Product Development Support Center failed to account for hours spent on each product, which will not only complicate the product cost calculations, but also the calculation of capitalization expenses later on. The Development Support Center will be most used during the peak (i.e. most hours) time of development for each product, and hours worked will probably be the best way to divvy up the costs of the support center. The money invested in the company is being used on developing each product right now. I figured interest would best be divvied up by hours to attribute the interest expense to the product using the most of the investment. Similar to the reasons stated before general and administrative costs are going to be associated with the most prominent product, and that is best seen through hours. (Figure A)
SUBPOINT: Workers would have to set a block every 2.5 minutes, 7 days a week in order to finish in 23 years.
The timesaving realized from start to finish of that inspection is 30-50% depending on the inspector and the aircraft.
The second step is to identify the direct costs of the job. There are two types of direct costs that need to be calculated: direct materials and direct manufacturing labor. When employees order materials they are recorded on a materials-requisition record which has information about the cost of direct materials used on a specific job in a specific department. Direct manufacturing labor is accounted for using a labor-time sheet which has information about the amount of labor time used for specific jobs in specific departments as well as the wage earned per hour. Any costs other than direct materials or direct manufacturing labor are considered to be indirect costs.
