Just In Time (JIT) Inventory Control

Just In Time (JIT) Inventory Control Just In Time Introduction Just In Time Inventory Control is a production method which views inventory as waste. Although it eliminates the need for inventory, it a complex process which is not easily implemented in companies. In order for a company to successfully implement JIT Inventory Control, different areas of statistics, industrial engineering, production management, and behavioral sciences have to be taken into account. Just in Time (JIT) is a tool for process improvement. This type of manufacturing system has allowed the company to substantially improve the value stream, that is, increase profitability and build high-quality, low-cost products at high efficiencies. JIT principles are closely aligned with lean manufacturing, another production concept that grew out of Toyota. Lean is an overarching philosophy which seeks to reduce waste throughout the organization. While JIT is one of several tools used to achieve lean, it can be implemented on its own. Lean practitioners have a language of their own, and the definition or application of these terms is often debated. Here are some common terms which are associated with lean practices and one accepted meaning for each: 5S A five-step method for creating clean, organized workspaces: sort, simplify, sweep, standardize, and sustain. Kaizen is known as an event in which team members evaluate procedures or equipment and seek to make improvements. Kaizen events are part of a continuous improvement process. In addition, Kanban is a visual sign or signal typically used to trigger an order for parts or materials, (Edward J. Hay; Wiley, 1998.) Description According to the traditional accounting practices, inventory holds and adds value. Just In Time, on the contrary, views inventory as waste that is constantly incurring costs. The waste is associated in terms of time, labor, and storage space. In essence, JIT Inventory Control produces only what is needed, when needed, and only in the amount required. JIT Inventory Control also produces the required units, in required quantities, with the right quality. There are many problems which can arise due to having little or no inventory such as work center backups, machine breakdown, variance in processes, problems with employees, lack of flexibility of employees and equipment, or even insufficient capacity. The main problem with JIT Inventory Control is that companies cannot predict total accuracy of material flows. Another problem that is encountered is that warehouse inventories fluctuate and inventories may be full or near empty at any given time. This makes it a task for members of manag ement to accurately plan logistics. History and Development Ford Motor Company initially used JIT in the early 1920s. This was later implemented by Toyota in 1954 who then publicized the concept. This concept helped Toyota cut down on overstocking car production. The concept focuses on eliminating inventory that doesnt add value to the product and it views inventory as a sign of poor management as inventory acts as a buffer that conceals problems in the production system. Toyota has proved to be one of the largest players in the auto industry. The company is headquartered in Toyota City in Japan and has plants worldwide. Cultural aspects It is necessary to consider several factors that influence the Japanese culture, which accelerated the evolution of JIT. Different Japanese characteristics, from which will take those that is considered the most relevant are lack of space: in Japan in general there is not room enough for mostly any activity, not surprisingly the reduction of inventories was welcome by the management. Commitment to consumers: consumers satisfaction has always been a priority. JIT is a pull production system that minimizes the waiting time of each buyer. This time starts when the buyer places the request for new products. Overcrowded living conditions: lead time shortages and maximum efficiency are a consequence of Japaneses requirements to improve their living conditions, either inside the company or within the society. Toyota aims at producing cars of high quality at a low cost. JIT Process Control enables Toyota to achieve this effectively. Toyota, especially being situated all over the world, has excellent labor relations. For Toyota, parts are delivered to the assembly line just in time for assembly. Supplier and labor relations are a crucial aspect of this process. Toyota holds and maintains close relationships with its suppliers and focuses on continuous improvement. Together, teams follow a decentralized method of decision-making and move forward with a motivated workforce. Employees are cross-trained to operate many different types of machinery. Toyota also uses â€Å"Andon† to show daily production figures and to report problems encountered on the assembly line. Toyota also focuses on total quality that is achieved through zero defects. This ties in with just in time inventory control. If a part is defective, the pro blem is traced to the source and the problem is attended immediately or the production line is stopped. Without excellent supplier relations, a large manufacturer cannot support a just in time manufacturing system. Parts are delivered many times daily and suppliers are also responsible for entire systems such as brakes, seats, and electrical systems. Since deliveries can be interrupted, Toyota uses two suppliers. A strong, long-term relationship with a few suppliers is better than short-term, price-based relationships with many competing suppliers. â€Å"Toyota uses this long-term relationship to send Toyota staff to help suppliers improve their processes. These interventions have been going on for twenty years and have created a more reliable supply chain, improved margins for Toyota and suppliers, and lowered prices for customers. Toyota encourages their suppliers to use JIT with their own suppliers.† Without cooperation and a dedicated workforce, success of the JIT Inventory Control system would not be possible for Toyota. Long term commitment and cooperation is essential for the success of JIT. Implementing JIT Just-in-time cannot be explained in a simple multi-step process. Naturally, every company presents unique challenges and opportunities. The following is a basic overview of just-in-time concepts. People involvement- whoever is related to the company that intends the implementation, shall be committed to the project. Starting with the machine operators and ending on the high level management, everybody has not only to be aware of the implications but to support the implementation as well. Implementation is a critic phase of JIT, and is advisable to avoid problems, to reduce the amount of time and efforts throughout this stage. Plants- numerous changes take place in the layout of the new plant. Some changes are easy to achieve as the so called productions cells, in which the machinery is located in a way that helps reducing the time it takes to move materials from one process to another. Nevertheless the introduction of Kanban (Japanese name of the cards that confirm material requirements), self-inspection, Material Requirement Planning (MRP) and MRP II (in case they were not already in use) and job enrichment within plant workers, involve structural change; thus they are far from being simple to implement. MRP I involves a computer system for building inventory, scheduling the production and to administrate inputs; on the other side MRP II, that stands for Manufacturing Resource Planning, includes the MRP Is activities plus marketing and purchasing operations and the financing function. Systems- existent systems may remain within the company; however the MRP and MRP II systems should be implemented. Further investments can take place, as the use of luminous Kanbans or the implementation of the Electronic Data Interchange (EDI) to link inventory existences with the suppliers. Purchasing- relationships with suppliers become a key factor not only in a JIT environment but in other production systems that intend to reach efficiency and to shorten production time. This issue is reviewed in depth on the 3rd part of this paper. Conclusion JIT Inventory Control is a very effective and efficient in eliminating waste. The process also enables companies to use more of the warehouse for assembly and production. Therefore space is not wasted and utilized instead to maximum capacity. This also reduces inventory costs. JIT Inventory Control requires cooperation and commitment between suppliers and the manufacturer. Without a close knit supplier-manufacturer relationship and reliability, JIT Inventory Control is useless. Although with many suppliers, manufacturers can expect price wars and competition enjoying lower prices. However, this puts reliability at stake. With limited or few suppliers as in the case with Toyota, a close bond can be maintained and reliability is not jeopardized. If it is possible, companies should adopt JIT Inventory Control and maintain long term supplier manufacturer relationships with dependable suppliers in order for the process to flow smoothly.

Real Friendship

Real Friendship Friendship is really hard to find in our lives today, especially in this world because according to us nowadays it is known as the quality or condition of being friends or just simply having a friendly relationship. A friend isn’t someone you randomly meet and know them just for who they are. My belief of a real friend comes as fate. If it is meant to be then it will happen because a true friendship lasts forever through good times and bad times. A friend is someone who is honest and dependable when is needed in certain consequences. That is why I believe in Cicero’s theories of friendship because a friend is someone who: . Thinks alike. 2. Is honest. 3. And understanding. This essay of real friendship focuses on these three main ideas. Thinks alike. I have a friend who is known to be my best friend since kindergarten. She is humorously been my friend for fourteen years and I hope it continues through out life. But the thing about her is that she is very much like me although our lives are very different according to our families and I am very thankful that she has been able to control her life on her own. Cicero says â€Å"A friend is, as it were, a second self† (Cicero, 1971). I consider Cicero’s theory to be right because according to other friends that I have had in the past have never been even close to what I have with my best friend. The ethical idea or the golden rule, â€Å"Do to others as you would have them do to you† (Fieser & Pojman, 2009). Applies to my friend and me because we always treat each other with respect and we don’t talk behind each other’s backs. We treat each other like if we were sisters. Is honest. Being honest is the quality of truthfulness. Honesty is something that should be required in a friendship because you are able to express yourself about anything. I am certain that most people can not accomplish any problems without being honest because if you are not, it just brings more problems into your life. â€Å"Friendship improves happiness and abates misery, by the doubling of our joy and the dividing of our grief† (Cicero, 1971). This quote is very important and meaningful to me considering that my best friend is there for me when I need advice and she is honest with me about it. I would not like for her to be dishonest, due to the choices I can make with her advice, and then she would not be a real friend because I will be making bad choices. In the Core Morality, rule number three is do not lie or deceive. â€Å"Language itself depends on a general and implicit commitment to the principle of truth telling. Accuracy of expression is a primitive form of truthfulness† (Fieser & Pojman, 2009). Honesty exists in my friendship and I really appreciate it now that I know what real true friendship is especially because we are moral to each other. Understanding. To know something or someone you must understand it or them. Just like how I know my best friend, she knows me and therefore we understand each other. I treasure our friendship for the reason that it has last so long and how we are uncomplicated. We rarely have any problems with each other, but when we do have problems we fix them as soon as possible. We do not like to let problems pass by because we do not like to fight or make bigger consequences. We come to an agreement until we understand each other. I really like how we can always settle our disputes unlike other relationships that I had who were so called my friends. â€Å"Friendship is the only thing in this world, the usefulness of which all mankind are in agreement† (Cicero, 1971). Any action taken into our friendship has always been our words and we always depend on the right act. â€Å"A right act that is permissible for you to do. It may be either obligatory or optional† (Fieser & Pojman, 2009). I think we have constantly picked obligatory because it is moral rather than optional. As a result I am happy we are still friends, through thick and thin. In completion, Cicero’s philosophy on friendship is very convincing and true because I never really paid attention to it. It makes you realize a lot about who your real friends are and who are not.

Why Marijuana Should Be Legal - 886 Words

Many people are pushing their state’s legislature to legalize the possession and sale of marijuana to persons over the age of 21. While many people believe marijuana is medically beneficial when used properly, just as many people disagree with this belief. The purpose of this paper is to give the facts supporting both sides of this proposal. Cannabidiol (CBD), and tetrahydrocannabidiol (THC) are the two main active chemicals found in marijuana that have positive medical benefits. Tetrahydrocannabidiol causes pain relief, and cannabidiol seems to impact the brain without a high. Marijuana when smoked can be used to treat the progression of some health conditions, such as glaucoma. According to the National Eye Institute studies in the 70’s showed that smoking marijuana reduced intraocular pressure in both healthy eyes and the eyes of a person suffering from glaucoma. In 2012 a similar study was published in the journal of the â€Å"American Medical Association† about marijuana. The study stated that marijuana does not impair lung function and can even increase lung capacity. In epileptics, marijuana has been proven to help control, or even temporarily stop the seizures all together. A study was conducted by â€Å"Robert J. Delorenzo† of Virginia Commonwealth University in which he administered marijuana extract, as well as synthetic THC to epileptic rats. The rats went without having a seizure for ten straight hours.
