STITCHING MACHINES
A sewing machine is a mechanical device equipped with a needle (or needles) threaded at the point-end, which puncture the fabric periodically as it moves under the needle; each stitch is created as the thread loops onto itself (chain stitch) or locks around a second strand of thread (lockstitch), sewing the materials together. Sewing machines are used in both the home and industry, but are designed differently for each setting. Those for the home tend to be more versatile in terms of the number and kinds of stitches they can perform, but they operate more slowly than industrial machines, and have a shorter life span. Industrial machines are heavier, have a much longer life span, are capable of thousands of stitches per inch, and may be designed for very specialized tasks.
Sewing machine is invented by Elias Howe in 1846 and successfully manufactured by Howe and Isaac Merritt Singer.

Types of sewing machine systems -There are three types of sewing machine systems * Mechanical sewing machines * electronic sewing machines, and * computerized sewing machines

Mechanical sewing machines are controlled by a rotary wheel. They have handles and disk to make changes in the tension or the length or width of the stitch.
Electronic sewing machine has more features than the mechanical sewing machine. Instead of turning handles or disk, electronic sewing machines use buttons to adjust length or width of the stitch. Electronic sewing machines have motors; and it is run by electricity.
Another type is the computerized sewing machine, which is very fast and easy to use. Computerized sewing machines are similar to electronic sewing machines. They use the same chips and stepper motors that are used in electronic machines. Besides, they possess a microprocessor which helps the sewing machine to accept new information in a card form and create

...As we can see, on the calculations; the company has chosen labour hours for the allocation base. But when we do the calculations with the machine hours with the allocation base, we face with a huge difference and moreover see a lower total cost, which make high the profit. Making profit higher will be a good thing, so the company should choose the machine hours for their allocation base and calculations. In addition; because of the technology improvement and automation; machinery will be more usable and effective. Moreover, because the machines will be heterogenous, we will then need different number of labor for each. Some of them is highly-automated whereas some of them is low-automated. So, again we understand that machine hours will be a better allocation base then labour hours. Labour hours Machine hours Standard products (high volume) 2500 3500 Specialised products (low volume) 1500 3000 Total 4000 6500 Difference Budgeted labour rate 42,5 279500/6500=43 -0,5 Budgeted overhead burden 149,825 599300/6500=92,2 57,625 Total Cost 192,325 135,2 57,125 2) As known, the most commonly used allocation base in traditional costing is direct labor hours. We can also see this in the case. But at this point, we may face with some problems such that in this process overhead is increasing while direct labor is decreasing. There is an 1800$ increase whereas 46% increase in the overheads dramatically. Moreover, we see a variance and complexity in the production process...

Productivity Is Difficult to Improve in the Service Sector

...Baumol (1967), many years ago stated that productivity improvements in services are harder to achieve than in goods producing industries. There is no exact data about this but only some notion of hypothesis by the economists and business men support Baumol that it is hard to improve productivity in service sector due to some reasons. Service industry means one is offering their service using a platform and most commonly used platform till today is the labour force. The first reason that leads to the difficulty in improving productivity of a company is because service industry typically needs the intensity in their labour force to compare to the manufacturing industry. This is because the labour will deliver their service to the customer. They tend to involve a significant amount of customization or customer interaction, so their operations rely heavily on these labours. The more services to be delivered or the more customers to be reached, the more labour force will be required which then, costly per each labour salary they need to pay. For example, Hotel industry is labour-intensive since they need to hire more labours to satisfy their customer since they are delivering intangible goods to the customers and the only important platform of delivering that service which is the labour, must be qualified and enough. Talking about the importance in delivering the service to satisfy the customer, this is said to be the other reason for its harder to improve the productivity in...

Case: Acme Manufacturing Company Case & United Machine Workers

...Manufacturing Company Case & United Machine Workers Introduction to the case analysis The legal aspect of every contract in business requires critical analysis for every term in accordance to the specifics upon which both parties are involved. The reason for analyzing such terms carefully is because it can become a crucial part in determining the decision making when addressing any business problem. This is generally more important from the perspective of the company management because some situations can result in high intensity and significance for the company. Analyzing the terms of a contract will help avoid any inappropriate or insufficient conclusions when presenting a final resolution in times of a dispute. The case to be evaluated in this assignment is the result from an opposing perception of an issue in which both party’s are involved. The grievance is the result from the opposing views on a subordination matter; that of the management’s perspective and that of the employee.

Technology Today

...efficiency of robots, but eventually a depressed job market would lead to a population that struggles just to feed themselves and their families, let alone purchase the products these robots make. In the long run, society will suffer if it does not take care to prevent the economic consequences of giving everything over to machines. Our careless use of automation has already taken a toll on our culture. People have been interacting with automation in nearly every aspect of their lives, whether it be shopping, banking, or the use of a telephone. The effect of this is obvious: basic respect for our fellow man is all but absent today because of increased interaction with automation. Why treat a machine with kindness? It suffers no emotional or psychological damage. In a culture saturated with automation, we get used to treating machines rudely, and we begin to treat each other rudely. This of course leads to all sorts of issues, like intolerence and incivility, and in the long run, results in the complete degradation of culture. Even in the face of these obstacles, some people argue that the increasing intelligence of today’s machines is a good thing. After all, machine power can decrease the human work load....

...Should machines be used to do good and services instead humans? I believe they should not for many reasons. Machines can not be smart unless a human is controling it. So it would not matter if its an intelligent machine or not a human is still controlling it to do everything. When using a machine it could easily malfunction and it could be hard to fix the problem or it will just take a while to fix it. If a human is taking over instead of the machine there may be fewer problems. Machines have so many problems that it would not be worth having. Also, the more machines you have the less jobs there are for people because everyone thinks it would be better to have machines instead of people. When less people are out of work that means less money for those people and sometimes they will lose their homes or cars because they can not afford anything. Sometimes working with machines can be very stressful because they may not work at times or they could be running extremely slow and won’t get anything done. Machines are not smart at all, only when people are controlling them they are but not all the time. It may seem smart but its really not. In conclusion, I think machines should not be used to take over a human job because machines can not think only humans can think and make right or wrong decisions. Machines do not have brains, their not wired to think so why have them do stuff that we can do...

Crane Operator Research Paper

...technology is now, it's pretty far, but can it replace a crane operator's human skills. Operating a crane requires good hand eye coordination, experience, safety precautions, and a knowledge of the crane limitations. The average age for this job is about 43, but most operators are older and are ready to retire. America is big, but its buildings are as well. They need maintenance that just could not be done without cranes. This is the ideal job for me because it's wage is high enough to provide for me, and the job comes with good financial benefits. Crane operators usually only operate one crane. There are mechanical, lattice boom cranes as well as cable or tower cranes and cable equipment to keep in shape. Crane operators lift and move machines, or materials for shipping or installation. There's different types of cranes for different jobs as well. This career excludes operating loaders and other equipment, but may be needed to be used once in a while("Certification Programs."). A crane operator's job includes more than just picking stuff and moving it around to another place. To operate, drive, and maintain the cranes to OSHA requirements, training, focus, effort, and testing to get a certification license, which needs to be renewed every 5 years on record. There are three different types of crane operators determined by the crane that they operate: tower cranes, overhead cranes, and mobile cranes. Tower cranes need to be set up and are not mobile by themselves. These cranes...
