Operations Management Essay Example for Free

Operations Management Essay 1. Discuss how just-in-time manufacturing might affect a Job Shop (Consider both positive and negative impacts on both internal and external operations). Just-In-Time (JIT) manufacturing may affect a Job Shop both positively and negatively. The most important affect is that it improves the performance of job shop production. JIT also eliminates waste and/or decreases work in progress (WIP) in that same sense. JIT allows for products that are produced to fulfill an immediate demand for them. JIT emphasizes on quality. Quality is very important in JIT manufacturing because it decreases or eliminates costs and increases profits by producing high quality products the first time around. JIT allows for quality products to be transformed from raw materials into finished goods as expediently and efficiently as possible without delay. Some of the negative affects are unskilled or untrained workers. They may not make quality products because they are not trained properly or often. It may affect external operations by promoting competitive bidding between vendors to provide needed inventory. Sometimes this can cause friction between long-standing vendors and the company when they’re out bid by another vendor. It can tarnish the business relationship. 2. You operate a dairy farm, raising cows for the production of raw milk products. Briefly identify the levels of vertical integration that you would anticipate being possible for such an operation (include both backward and forward integration in your response). Operating a dairy farm, raising cows, would be a very challenging business to conduct. The competition for market share is outrageous. One level of vertical integration that I would anticipate is to possibly setup my own distribution center. I would face some challenges because I’d have to hire workers with this type of expertise, along with the knowledge of farming. Though I’d have to invest more capital and purchase or allot warehousing space for the added inventory, in the long run it would be much more economically beneficial to my farming business. I would become my own distributor, thus passing these savings to my customers, while gaining market share. Another level of vertical integration would be that I’d purchase more land to have grass to feed my cows, instead of purchasing feed from a feed company. That type of integration is called forward integration. 3. Discuss the concept of the â€Å"Process Spectrum†. Use examples where appropriate. The Process Spectrum is made up of five major types of manufacturing processes that a company may use to get to an end product, or a finished good or service. The continuous flow process is characterized by the flow of material. During this process, the material hardly ever stops, but moves constantly from one process to another. Using the continuous flow process, the time to transform raw material into a finished project can be easily estimated. The Job Shop process is the most flexible of the processes. Unlike the continuous flow process, the Job Shop process it group’s similar equipment together. This most often allows for products to flow from one machine to a different type of machine and back to a previous type of machine, if needed, unlike the continuous flow process. This process fulfills an outside customer’s order by an agreed-upon date and whatever quantity ordered. The batch flow process is most similar to the job shop process, in that the equipment is grouped by function rather than product. Unlike the job shop process, it produces products in an established lot size that move into an inventory from which further production or final customer orders are filled. The Line Flow process mostly resembles a moving assembly line, such as in the auto industry. In contrast to the continuous flow, the line flow is more flexible, less automated, and more labor/worker driven. The hybrid process is where the first part of the flow of materials resembles the batch flow process, while the latter part resembles a line or continuous flow process. In a hybrid process, on process separates the inventory by parts or semi-finished inventory, to be passed to the other process for assembly or finishing. 4. Compare and contrast the â€Å"Worker Paced Line Flow Process† and the â€Å"Machine Paced Line Flow Process† as relates to capital use, process speed, pacing, and materials requirements. In comparing and contrasting the â€Å"Worker Paced Line Flow† and â€Å"Machine Paced Line Flow† processes in reference to capital use, it is fairly cheap to manufacture and or service the customer base in the worker paced line flow than the machine paced line flow. Though the equipment is specially designed to produce the quality products of the company, the difference in capital use is greater in the machine paced line flow because the operations are most likely larger in size than the worker paced line flow process. In a worker paced line flow, the process of making raw material into a finished product is increasingly fast, such as in a fast food restaurant. The customers expect to be served in a decent time frame and expect their food to be fresh, hot, and in good or great quality. The product flow depends on the immediate demand. The greater the customer base, the greater the need to produce products and in a faster pace. However, it is still dependent upon the pace of the workers and their pace is monitored and adjusted by management as deemed fit for customer demand. In a machine flow process, the process of speed is fast. This is based upon the speed of the machine producing the product. However, machines can be set to achieve a set goal by management. In reference to materials requirements, in a worker paced line the amount of material or inventory needed or required is closely estimated by the amount of sales. In a machine paced line flow process, the amount is not known for certain until a production plan is established. 5. Briefly discuss the concept of the â€Å"cost of quality†. Consider both positive and negative costs associated with a typical quality program in a manufacturing facility. My understanding of the term â€Å"Quality is Free† is to make the product to specifications the first time, as to avoid the costs associated with correcting all of the defects. Poor quality could lead to poor customer relations, which is bad because most businesses are advertised through â€Å"word of mouth†. To scrap means to start over from the beginning. That’s not good because you’ve made the product twice at twice the cost. Costs can be mitigated when the products are inspected and tested to detect defects at different stages of WIP, before rolling out to the market. This is a good process to have in place. Ensuring workers are properly trained and cross-trained is a good preventative measure to have in place. The more processes a worker can perform, the more productive the company can be.

Educational Goals and Philosophy :: Teaching Teachers Education Essays

Educational Goals and Philosophy My idea of the perfect teacher is one that gets the right message across to all students. The perfect teacher would show his or her students good morals and ethics, and still yet deliver to the students what is in the text. The teacher would not necessarily have to teach straight from the book, but just getting the message across is the key. That might even involve a field trip or a hands-on activity, as long as students learn the best way. The best way to learn in my classroom will be the fun way. I will try my best to be as close to the perfect teacher that I can be. I will look at teaching through three of the four philosophical standpoints: idealism, realism, and pragmatism. The most emphasis will be placed on idealism. This is because I want to look at myself as a role model for the children. I also don’t believe in sending students to the office unless it is absolutely necessary. Kids this day in time don’t mind being sent to the office because they don’t want to do the class work anyway. It would only be doing them a favor to send them to the office. I am about half and half on realism. Some of the realist strategies would be very useful in the classroom but there are some I absolutely don’t agree with. I would really like to incorporate technology into the classroom because it is necessary for all children to master technology in the age we live in today. The rules and regulations will also be posted in the class at the beginning of the school year. However, students will not be grouped according to how good their test scores are. From pragmatism I will look at the classroom as a community of learners and apply problem-solving techniques. The students will also learn by engaging in activities first-hand, they do this because when the students start to get bored with what they are doing they quit learning.

Macbeth †Hero or “Hellhound” Essay

William Shakespeare the author of Macbeth was born in April 1564 in Stratford-upon-Avon, England. He is generally regarded as the greatest playwright ever to have lived. During the time of Shakespeare (which was the Elizabethan times) the theatres in which his plays were performed were very basic. They had no scenery or sets so they used simple items such as a stool, which would represent an indoor scene. He theatres were also very small, the fortune theatre only being 80ft square. The stage had three tiers; the main stage where most of the scenes would be performed, the tiring house which was used for scenes such as the witches’ cave in Macbeth and the gallery (upper stage) which was used for scenes such as the balcony scene in Romeo and Juliet. People in the Elizabethan times were extremely religious and believed in a â€Å"chain of being†. This is a hierarchical society that is divided into three sections, Heaven, Hell and Earth. They believed that everybody was born into a level and this could not change or chaos would ensue. Due to this belief the killing of king – known as regicide was regarded as the worst crime in the world as the king was god’s messenger on Earth. Macbeth was written for King James in around 1605. Because of whom it was written for Shakespeare had to change the character of Banquo to a â€Å"good guy† as it was one of James’ ancestors (Shakespeare actually borrowed the idea for the play from Ralph Holinheads’ chronicles). The play is about a Scottish nobleman ‘Macbeth’ who becomes king by murdering the previous king. The world is then thrown into disarray until eventually ‘Macbeth’ himself is killed and the true successor to the throne is crowned when order is restored. There are many themes in Macbeth many of which recur throughout the play. These include masculinity. Lady Macbeth always questions ‘Macbeth’s’ manhood whenever he doesn’t want to go through with something, which leads to ‘Macbeth’ doing whatever she wants him to. Linking with this is femininity, during the play Lady Macbeth refers to this when she calls for the spirits to â€Å"unsex† her. There is also the theme of darkness, which creeps up a few times during the course of the play. ‘Macbeth’ says to the stars as he is about to murder Duncan, â€Å"hide your fire, let not light see my black and deep desires.† Lady Macbeth also asks for darkness when she says, â€Å"come thee thick night, and pull thee in the dunnest smoke of hell.† Evil is regularly associated with darkness and these references show that there is an evil side to ‘Macbeth’ and Lady Macbeth. Perhaps the most important theme in the whole play however, is fate. Every character except from ‘Macbeth’ accepts fate and the fact that they don’t have any control over it. In the first scene ‘Macbeth’ is said to â€Å"disdain fortune† and later on in the play the witches lead ‘Macbeth’ to believe that he can have complete control of his destiny, which, he later realises he cannot. The ‘tragic hero’ is a character used quite often by Shakespeare. The tragic hero is a character who is noble, brave and good but always has one fatal flaw. In ‘Othello’ the fatal flaw is jealousy and in Macbeth the fatal flaw is ambition. The tragic hero’s fatal flaw will inevitably result in their death, hence the name ‘fatal flaw’. I am now going to work through the play discussing the question ‘Macbeth’-Hero or â€Å"Hellhound†. The play starts with thunder and lightning, which is seen as a reference to the Gunpowder Plot, which occurred around the same time as the play. The Elizabethan audience would recognise this and see the relevance because in both the case of the Gunpowder Plot and the play the intended victim was the king. The meeting of the witches is the first scene in Macbeth. This shows that the witches are a very important part of the play and they will be very influential during its course. The audience will know to be afraid of the witches because of the society of the time. To the Elizabethans witchcraft was a fact of life. We also discover that the witches are definitely a source of evil when they say, â€Å"fair is foul, and foul is fair, hover through the fog and filthy air.† This shows that the witches are trying to disrupt the natural order, which, according to the chain of being will throw the universe into chaos. In the second scene we learn of ‘Macbeth’s’ bravery in battle. This where he is said to â€Å"disdain fortune† which shows us that he doesn’t believe in fate. We also find ‘Macbeth’ is a very strong fighter and that; he and other people believe that he is unbeatable in battle. An example of this is when the captain says, â€Å"yes as sparrows eagles: or hare the lion.† This is a reference to ‘Macbeth’s’ fighting ability and the fact that he is as scared as a lion would be of a hare. When the opposition army is refreshed and with new troops the captain says, â€Å"As cannons overcharg’d with double cracks, so they doubly redoubled strokes upon the foe.† This shows the audience how ‘Macbeth’ but will make them wonder is he too bloody and over the top? ‘Macbeth’s’ first words in scene three are, â€Å"so foul and fair a day I have not seen.† The audience will pick up on this as it links in with what the witches say at the beginning of the play. The audience may also be a little disturbed by the way that ‘Macbeth’ seems to be acting now. The witches know what ‘Macbeth’s’ name is and this startles ‘Macbeth’ and the audience. They say â€Å"All hail Macbeth, hail to thee Thane of Glamis.† The audience will now begin to realise just how powerful the witches are as this is little known information. They then say â€Å"All hail Macbeth, hail to thee Thane of Cawdor.† Of course by now the audience will know that the Thane of Cawdor is a traitor but they don’t know how the witches have this knowledge. This will scare the audience and make them wary of the witches’ behaviour. Banquo mentions to ‘Macbeth’ that he should be happy by this news, â€Å"Good sir, why do you start, and seem to fear things so fair?† This shows us that the witches have also startled ‘Macbeth’. Does this mean that ‘Macbeth’ can’t be too evil as he is scared of the witches or he is just shocked because he has already thought of murdering the king? Banquo also says that ‘Macbeth’ seems â€Å"rapt withal† so we wonder if he is deep in thought or under a witches spell. If ‘Macbeth’ is in fact under the witches’ spell then his actions throughout the rest of the play can’t really be seen as his fault. Banquo seems to be aware that the witches are evil although ‘Macbeth’ isn’t. â€Å"Cannot be ill. Cannot be god.† Is he just reassuring himself or is he really not aware that the witches are bad? ‘Macbeth’ thinks of murdering the king and is scared by his thoughts: â€Å"Why do I yield to that suggestions whose horrid image doth unfix my hair, and make my seated heart knock at my ribs, without the use of nature.† Again Banquo says, â€Å"look how our partners rapt† so again we wonder if he is under a spell or just deep in his thoughts. The way that this idea of ‘Macbeth’ being â€Å"rapt† could be Shakespeare’s way of telling the audience that ‘Macbeth’ is being controlled by something more powerful than just his mind or ambition. In the next scene Duncan announces that the successor to the throne will be his son. ‘Macbeth’ also declares his loyalty to the king when he becomes thane. The audience will already know that ‘Macbeth’ has had thoughts about killing the king and therefore will see this as ‘Macbeth’ being very two faced. ‘Macbeth’ also says in this scene: â€Å"the Prince of Cumberland: that is a step, on which I must fall down, or else o’erleap for of in my way it lies. Stars hide your fires let not light see my black and deep desires.† This reveals a lot about ‘Macbeth’s’ current train of thought. He is basically saying that the Prince of Cumberland is in his way and must be overcome. ‘Macbeth’ also becomes quite scary in this speech when he says the part about â€Å"Stars hide your fires†. This will symbolise to the audience that he is moving into darkness from light or more worryingly from good to bad. In scene five Lady Macbeth is introduced. She offers quite a lot of insight into ‘Macbeth’s’ character that hasn’t been mentioned before. She says, â€Å"Yet I do rear thy nature is too full of the milk of human kindness.† This is a feminine quality; she is basically that ‘Macbeth’ is not masculine – bloody enough. She also says that he is, â€Å"without the illness that should attend ambition.† This means that his ambition is pure but does not having that â€Å"illness† mean that ‘Macbeth’ doesn’t have a conscience? She says that he wants to do things the right way, â€Å"holily†, â€Å"wouldst not play false† and also that ‘Macbeth’ fears to do things. This shows us that Lady Macbeth has, perhaps, a confused idea of masculinity and femininity and also good and evil. Lady Macbeth’s behaviour echoes that of the witches as she calls upon the spirits to â€Å"unsex† her. We can also links with ‘Macbeth’ when she says, â€Å"come thee thick night, And pull thee in the dunnest smoke of hell.† Here she is calling for darkness like her husband did previously. ‘Macbeth’ arrives home at their castle and tells Lady Macbeth that Duncan will be staying for a night, to which Lady Macbeth says, â€Å"O never shall sun that morrow see.† This is a clear indication that she too wants the king to die. She tells ‘Macbeth’ to â€Å"look like th’ innocent flower, but be the serpent under’t.† ‘Macbeth’ says â€Å"we will speak further.† This shows the audience that ‘Macbeth’ hasn’t yet decided whether or not to kill the king. In scene six the king arrives at ‘Macbeth’s’ castle. In scene seven ‘Macbeth’ argues against killing the king by saying, â€Å"he’s here in double trust.† This means that it should be ‘Macbeth’s’ duty to protect the king and not try and kill him. He also says to Lady Macbeth, â€Å"we will proceed no further in this business.† Lady Macbeth retaliates to this by saying that ‘Macbeth’ is a coward and she follows it up by saying something extremely shocking. She says that she has had children but would rather rip the baby from her and kill it then break her vow to kill the king. This shows to us that it may not just be the witches who are proving to be a bad influence on ‘Macbeth’s’ mind. This causes ‘Macbeth’ to change his mind. Lady Macbeth outlines a plan to kill the king. Her idea is to get the king’s guards so drunk they fall asleep then Duncan will be unguarded. Once Duncan has been killed she will pour blood on the guards to make it look like they murdered him. ‘Macbeth’ ends the scene by saying, â€Å"I am settled.† He has decided to kill the king. We wonder whether this was perhaps his intention all along or was it Lady Macbeth’s intervention that pushed him to do it? In Act two scene one ‘Macbeth’ starts on his mission to kill the king. A dagger appears before him. There are lots of interpretations about what this means. Is ‘Macbeth’ going mad and just imagining it? Is the dagger really there? Is it a witches’ spell making him see it? Some versions of Macbeth actually show the dagger appearing before him while some don’t, as if it is in his mind. In scene two ‘Macbeth’ kills the king and is in a terrible state. He says, â€Å"I could not say amen.† This could be evidence that he is under a spell because if he was just evil it wouldn’t bother him that he couldn’t say amen. He also says, â€Å"me thought I heard a voice cry, sleep no more.† This shows that ‘Macbeth’ is both hearing and seeing things. This will make the audience wonder if ‘Macbeth’ has truly gone mad or if he just feels guilty about it. In scene three we see the chain of being has been disrupted and chaos is ensuing when it is said, â€Å"some say the earth was feverous, and did shake.† Also in this scene Macduff finds the king dead. ‘Macbeth’ kills the servants. Is this ‘Macbeth’ being careful and cautious or just bloody? In the first scene of act three we realise that Banquo suspects ‘Macbeth’ of getting in to the position he is in more by foul play than coincidence. â€Å"I fear thou play’dst most foully for ‘t.† We wonder whether Banquo suspects ‘Macbeth’ because he knows that ‘Macbeth’ is capable of doing this. ‘Macbeth’ says, â€Å"to be this is nothing but to be safely this.† ‘Macbeth’ is pondering whether he should kill Banquo, after all he saw the witches and he knows what ‘Macbeth’ is doing. He also says, † come fate, into the list.† ‘Macbeth’ is personifying fate again, which links with when he is said to â€Å"disdain fortune.† This is very important because it shows that ‘Macbeth’ is now acting against the witches as he has decided to kill Banquo and his son. This time however ‘Macbeth’ gets â€Å"murderers† to kill Banquo. Is this because he is too scared? Does he still feel some loyalty to Banquo? Or is he just being more devious? He says to Lady Macbeth, â€Å"Be innocent of the knowledge, dearest chick.† This is a huge step for ‘Macbeth’ because the murder is all his own planning and no witches or wife are persuading him. He also says, however, â€Å"O, full of scorpions is my mind, dear wife.† This shows that, again, ‘Macbeth’ is showing some remorse. This shows us that ‘Macbeth’ does not become purely evil immediately. In scene four Lady Macbeth says ‘Macbeth’ is â€Å"womann’d.† In Shakespeare language this means that it is good to be kind, good to be scared. Theses are all necessary parts of being a hero, not a villain. In this scene Banquo’s ghost appears before ‘Macbeth’. We wonder again, as with the dagger, is this a spell, a hallucination or just his guilty conscience playing tricks on him. ‘Macbeth’ says â€Å"I will to-morrow (And betimes I will) to the weird sisters, more shall they speak.† ‘Macbeth’ is going to see the witches. He knows that he has gone too far and cannot be good again. He has â€Å"embraced evil.† â€Å"For know I am bent to know the worst means the worst.† The audience will now wonder whether this is ‘Macbeth’ being brave or just purely evil. In scene five the queen witch says that ‘Macbeth’ isn’t linked with the witches. The audience will wonder is the witch lying? And also is this good or bad? If ‘Macbeth’ is linked with the witches then they can be blamed for his actions but, if what the witches are saying is true then ‘Macbeth’ is responsible for his own actions. Act four scene one. The witches produce apparitions as they talk to ‘Macbeth’. The audience will link this with the dagger and Banquo’s ghost and will now believe that the witches are the cause of these images. The witches’ first warning to ‘Macbeth’ is clear. â€Å"Beware Macduff, beware the Thane of Fife.† The second apparition is a bit more cryptic. â€Å"for none of woman born shall harm ‘Macbeth’.† The witches know that they are tricking ‘Macbeth’. At first ‘Macbeth’ decides not to Macduff as he thinks he can’t be harmed by him but then changes his mind to be on the safe side. This is another example of one of the many times ‘Macbeth’ goes a bit over the top by killing people. The third apparition tells ‘Macbeth’ that he will be safe until the wood marches up to the castle. This makes ‘Macbeth’ feel safe as he thinks, that the wood can’t march and that everyone is woman born. The audience however, will know not to trust what the witches say. In act five scene two we see some peoples’ opinions of ‘Macbeth’. â€Å"Tyrant, mad and valiant fury† are all mentioned. The audience will know that ‘Macbeth’s’ reign is likely to come to an end. In scene three ‘Macbeth’ learns that the English are marching into Scotland. ‘Macbeth’ says, â€Å"I’ll fight till from my bones, my flesh be hack’d!† This is another point in the play where ‘Macbeth’ is very bloodthirsty and over the top. In scene five ‘Macbeth’ hears a scream. Lady Macbeth has died. He says: â€Å"I have almost forgot the taste of fears, the time has been, my senses would have cool’d to hear a night-shriek, and my fell of hair would at dismal treatise rouse and stir as if like were in lit.† This isn’t a good sign as it shows that ‘Macbeth’ has gone too far. He also says: â€Å"She should have died hereafter, there would have been a time for such a word, tomorrow and tomorrow and tomorrow creeps in the pretty face from day to day.† This shows that ‘Macbeth’ is accepting that he will be defeated and wants death now. ‘Macbeth’ also learns that Burnham wood is coming to the castle. He says, â€Å"at least we’ll die with harness on our back.† The audience will wonder of this is noble and heroic or is he really mad? It also shows that ‘Macbeth’ â€Å"disdain fortune† once again. In scene seven ‘Macbeth’ realises that he has been tricked by the witches when he says, â€Å"they have tied me to a stake, I cannot fly, but bear like I must fight the course.† The audience may now feel a little bit sorry for ‘Macbeth’, as all that he can do now is fight. â€Å"Turn hell hound, turn.† Macduff yells to ‘Macbeth’ to which ‘Macbeth’ replies no. He decides that he doesn’t want to kill Macduff as he has already killed all of his family. Is this ‘Macbeth’ showing some compassion to Macduff by not fighting him or is it just arrogance? ‘Macbeth’ realises what the witches were talking about when Macduff says he was born by caesarean section – not born of a woman. Even though he now knows this he still wants to fight. The audience will wonder if this is ‘Macbeth’ trying to â€Å"disdain fortune† once again. Macduff kills ‘Macbeth’ in the fight, as the witches predicted. Malcolm says, â€Å"this dead butcher.† This isn’t really a very good description of ‘Macbeth’ as he perhaps had good reason to kill some of the people that he did and some of his other murders could be seen as ‘Macbeth’ being cautious rather than bloody and over the top. When the king’s named successor returns to the throne, the chain of being is back in order and the play ends. ‘Macbeth’ has been killed and order has been restored.

Character Analysis Of Bhool Bhulaiyaa - 840 Words

A Bollywood horror psychological movie â€Å"Bhool Bhulaiyaa† was directed by Priyadarshan. The leading characters in this movie are Akshay Kumar as Dr. Aditya Shrivastav (psychiatrist), Vidya Balan as Avni who suffers from DID (Dissociative Identity Disorder), Shiney Ahuja as Siddharth (Avni’s Husband), Ameesha Patel as Radha (Siddharth’s cousin), and Manoj Joshi as Badrinarayan (Ameesha’s father and Siddharth’s uncle ). This movie is placed in a small village of India. Badrinarayan plays a role of Brahmin (member of high class Hindu religion) whose ancestral castle is belived to be haunted by a ghost of Bengali dancer Manjolika. One day son and daughter in law of Badrinarayan, Siddharth and Avni return to the village from United States of†¦show more content†¦He tells him that he visited Avni’s hometown to know more about her childhood and gets the evidence of the problem. In order to cure her disorder, he tricked her by a dummy of Siddharth and she thinks that she is killing the king. After this Manjolika’s personality left Avni’s personality forever. Dissociative Identity Disorder is also known as multiple personality disorder; this disorder is described as a switching different identities in which a person develops two or more personalities or identities. A person feels the presence of two different people living inside their head, and may feel as though they’re possessed by other identities or ghost. Each identity has a unique name, history and characteristics. It includes differences in voice, gender, mannerisms and other such physical qualities. There also are differences in how familiar each identity is with the others. People with dissociative identity disorder typically also have dissociative amnesia and often have dissociative fugue. Dissociative amnesia and fugue are usually attributed to excessive stress. Symptoms may include memory loss (amnesia) of certain time periods, even ts, people and personal information. A person may face the sense of being detached from themselves and their emotions. Perception of the people and things around them seems unreal. Significant stress or problems may occur in person’s relationship, work or other important areas of life. The most common problem is
