Wildlife on and Around Airfields :: essays research papers

  Ã‚  Ã‚  Ã‚  Ã‚  The danger of wildlife, particularly birds, on and around airfields has become a major issue on military bases. Hour upon hour is spent researching and testing methods to protect the wildlife, personnel, and aircraft. Despite these gallant efforts there are thousands of mishaps every year.   Ã‚  Ã‚  Ã‚  Ã‚  In the past, the effect on the environment and its living creatures wasn’t a top issue when building military bases. Unquestionably, it has been a concern though. Since flying first became a reality, documented safety reports go back as far as eighty-eighty years. As a result of not making it a number one priority, today we have problems with environmental organizations under the Endangered Species Act and millions of dollars are spent on scientific systems and even more lost to accidents and fines. There was no way obviously when airfields were being constructed that the significance of this matter could have been predicted. However, with a little more effort years ago and not just within the last twenty, many hazards could have been avoided.   Ã‚  Ã‚  Ã‚  Ã‚  Because of the numerous wildlife strikes to aircraft, literally millions of dollars in damaged parts are spent and millions are lost to complete destruction to aircraft. On the average, 3,126 strikes are reported each year by the military at nearly an average cost of $12,000 per case. This has led to over $700 million dollars lost or spent on aircraft over the past 20 years. Over all, the United States alone has lost $300 million annually, so you can tell the problem is not a small matter. Equally important are the fines handed out. Such as the case involving an international airport in France, where a flock of birds that was feasting on a carcass was neither reported nor removed before a jetliner was to depart. The plane received damage when it attempted to take-off but avoided serious consequences by shutting down just before the end of the runway. The airport was fined $3,000,000. Along with the financial losses, there have been several injuries and, more importantly, human fatalities. Possibly the most dramatic military incident was one in which several birds flew into a plane cruising at a high altitude. Damage was done to the engines and cockpit windows, causing the plane to crash and kill all 24 passengers. Over the past 30 years, a total of 37 Air Force aircraft have been completely destroyed, bringing along with it 35 fatalities.

Read the case, and answer the following questions:1.Search in the library (books on Operations Management or Production Management), to find the main components of the â€Å"Aggregate Production Planning† problem and briefly describe which are â€Å"pure strategies† and â€Å"mixed strategies† to solve this problem.The aggregate demand is the total demand for all products/services produced by a production facility without considering size, models, etc., usually there are significant seasonal variations. The objective of the Aggregate Production Plan is to manage production in order to meet the aggregate demand, matching capacity with demand fluctuations.The main components of APP are: external (Market Demand, Economic Conditions, Raw Material Availability and Competitors Behaviors) and internal (Production, Workforce Level, Inventory Level, Subcontracting, Backlog Policy, Physical Plant Capacity, Union Agreement, Capital Limit, among others).The mentioned compone nts can be modified to create production strategies which can be applied to this problem:Pure strategies: Considering one variable at a time to demand fluctuation: 1.Varying Workforce Level (Hiring or Firing). 2.Varying Production Rate (Overtime/Length of Work Hour) 3.Varying Inventory Level (High or Low).Mixed strategies: Considering two or more variables at a time to demand fluctuation: 1.Varying both Workforce Level and Inventory Level. 2. Varying both Production Rate and Inventory Level.2.Find the following parameters of the problem (specify the units involved):Productivity450 app/worker-year Expected for next year: 480 app/worker-year Regular Labour Cost$10.50/hr-worker Overtime Labour Cost1.5 times the regular hourly rate; $15.75/hr-worker Hiring Costs$1,800/worker Layoff Costs$1,200/worker Inventory Holding Costs$8/app-month Initial capacity13,000 app/month Beginning Inventory240 app3) What are the main advantages and disadvantages of each of the actions (page 2, item 6) avai lable to the company to meet demand? How can these actions be combined?1.Building inventory to meet peaks ïÆ' ¼Protection against unforeseen demand changes. ïÆ' ¼Inventory accumulation will be drawn down during peak demand periods. XIn periods of low demand, inventory would be accumulated and it would generate high holding costs.2.Using overtime ïÆ' ¼No inventory carrying costs. ïÆ' ¼Workforce held just to meet average monthly requirements. XExcessive overtime might lead to lower efficiency. XRestricted production might promote poor work habits and low morale.3.Hiring and laying off workers ïÆ' ¼The cheapest alternative. XUnion relations and employee morale could be adversely affected by frequent layoffs. X Hiring and training employees would be a problem (limited labour market).4) Replicate in an Excel spreadsheet, page 4 (Exhibit 1). It's not just to copy the spreadsheet, but to write down the formulas to incorporate the production flow balance. A similar flow balance can be obtained for workers.  There are also formulas to include all the costs involved. Although you may discuss these questions with your team, you must submit your work individually.

Langston Hughes, Prolific Writer of Black Pride During the...

During a time where racism was at its height in America through Jim Crow laws in the South, laws that separated blacks from mainstream white society. Where the notion of â€Å"separate but equal† was widely accepted in America, blacks were faced with adversity that they had to overcome in a race intolerant society. They were forced to face a system that compromised their freedom and rights. Blacks knew that equal was never equal and separate was definitely separate (George 8-9). Blacks had to fight for their rights because it wasn’t handed to them. Racism manifested itself on many levels and had to be fought on many levels. This gave rise to influential black leaders in the fight for civil rights. Langston Hughes was one of those black leaders†¦show more content†¦This excerpt shows how at the time of segregation young black artist were willing to give up their ethnic uniqueness to become assimilated and accepted into the white society. One can understand this act of shedding oneself to be accepted into a society, where if an individual was not the majority they were not counted as equal. So in order to have their work recognized black artist had to hide or want to hide their identity which was their skin color, in order to be acknowledged as equal. Hughes wasn’t afraid to express the truth when he said that this young poet would not be a great poet if he continued to run from his race and not accept who he is. Hughes felt that blacks should be comfortable in their own skin and not have to succumb to the white American standard. Through this manifesto Hughes became a spokesman for young black writers and artists, showing them that they don’t have to be white to be great, although society may believe that. Black is beautiful and we cannot be afraid of our uniqueness. Hughes was able to express his creativity and ideas through different genres of writings. Through his writings he was able to give his people a voice and tell th eir story and history, showing that the black community was part of the American experience. â€Å"The White Ones† and â€Å"The South† are two of Hughes poems that expresses the black experience. In â€Å"The White Ones† Hughes expresses the notion of â€Å"torture†. â€Å"O, white ones why do you torture me?† This lineShow MoreRelated Langston Hughes, Prolific Writer Of Black Pride During The Harlem Renaissance1658 Words   |  7 PagesDuring a time where racism was at its height in America, Jim Crow laws separated blacks from mainstream white society.
