Why Logistics Is Important 'logistics is defined as the process of planning, implementing, and controlling the efficient, effective flow and storage of goods, services, and related information from point of origin to point of consumption for the purpose of conforming to customer requirements.' Note that this definition includes inbound, outbound, internal, and external movements, and return of materials for environmental purposes' (Council of Logistics Management, 2011). Logistics has played an important part in human society since the early known recollection. Land based logistics is the oldest form of transportation since before recorded history and is still in use today. Land based logistics has evolved with technology to incorporate many different kinds of transportation. All of these technological advancements have made it easier for human life to flourish. These advancements in technology have allowed human kind to also explore and interact with each other around the world. Sea based logistics is the second oldest form of transportation. Sea based logistics has become made exploratory and mapping of the world possible. Sea based logistics allows many of the developed countries to continue to advance. Sea based logistics also allows for under developed countries to benefit from the advancements made in by developed countries. The further advancements in sea based logistics can provide peace and prosperity for the entire planet. Air based logistics is the newest in the transportation realm. Air based logistics is used by both civilian and military departments. There are many new concepts that are arising from old technology to make air based logistics more manageable. Although air based logistics is fairly new, there are still many bugs to work out in the system. Air based logistics is the newest and fastest way of delivering passengers and cargo. It is important to understand each and every one of these types of transportations. Land based transportation has brought villages closer together. Sea based transportation allows from products to travel across the world at ample speed. Air based logistics allows for the rapid delivery of cargo and passengers. These types of transportation made logistics easier to manage. But with the management of these types of transportation there is also disaster. Land-Based Logistics Land based logistics is the oldest form of transportation. Even before there were combustion engines many walked between their destinations. They also carried their goods for trade and barter. No one knows when the domestication of animals took place but it made travelling faster as well as carrying a greater amount of cargo. An example of this can be seen in the 'ships of the desert' also known as camel caravans or camel trains (Thompson, 1998). It is uncertain who invented the wheel, according to many archaeologists it is presumed to have been invented around 8000 B.C. in Asia, although the oldest wheel that has been discovered in Mesopotamia and dates back to 3500 B.C. (ThinkQuest,2010). Along with the wheel and domestication of animals, great inventions came along such as the chariot and more modernly the horse drawn carriage. Although these types of transportation are vital in third, fourth and fifth world countries, it is rarely used in developed countries. Human kind has not been satisfied with animal power. The invention of steam and combustion engine during the industrial revolution has allowed for greater transport and logistical advancements. The steam engine was widely used to in locomotive trains in the eighteen and nineteen hundreds. With the development of further railroads heading west trains became longer and faster. There are disasters that took place one of the most famous explosions of a steam engine occurred on July 3rd 1927, the engine was Maine Central # 505. 'July 3, 1927: Maine Central #505 was in Bartlett having come in on the 'Local' Portland, ME to Bartlett, NH job the night before. The Roundhouse was short on power so the 505 was to be a 'helper' locomotive. It was rare for her to be used as a helper as this was the case for all the Class W's. These were used almost exclusively east of Bartlett, where they really shine. 505 were due to go back to Portland on the afternoon local later that day. She was pressed into service to help with a very 'heavy' extra. She would be put in mid train, and cut off at Crawford's. Bob Morse and Oscar Clemons planned an afternoon fishing trip for when they returned. There would be 2 locomotives on the head pin. As the Engineer, Bob Morse worked the engine, to help make up the train; the throttle felt 'Soggy'. He reported it to the mechanics at the Bartlett Roundhouse, they checked the loco over, but could not find the problem. Bob and his fireman, Oscar Clemons, went back to work. Again, Bob reported the sluggish response of the 505; the shop crews brought her in to the Roundhouse and did everything but dump the fire and pull the boiler jacket off, which Bartlett was not equipped for anyway. So at about 8:00 the 505 took her place, on a WESTBOUND extra freight, about mid train. The train departed at about 8:30 a.m. Bob Morse was a popular man, but pushed his locos to their operational limits, he got every bit of operational power out of the engine he was running, and he was very good. One trick almost all engineers had in those days been to run the loco water low. This gave you the maximum amount of steam pressure and the maximum performance from the loco, but the engineer had to have a fireman that could handle the task, it was a dangerous dance, but Oscar Clemons had worked with Bob Morse for years and knew exactly what he was doing. At about 10:00 the train passed Willey House Station, Mile post 81 about 1/4 miles up the track it becomes straight and levels off. The 505 was traveling at 40 MPH under past maximum pressure, when the loco reached this point Oscar opened the petcock for water and the engine exploded. The boiler failed just in front of the drive wheel 2nd from the firebox (3rd driver from the front). The explosion blew Engineer Morse out of the cab and 500 feet back. The Locomotive lifted clean out of the train, fracturing the connecting bar between the engine and tender, flew up in the air 60 feet, turned end for end and dropped upside down and over the bank, crushing the cab with Oscar Clemons still inside, before rolling back on her side and coming to rest. Investigators found that the sight glass used to measure the water in the boiler was faulty, the boiler plates failed due to metal fatigue and the soggy feeling Mr. Morse was feeling while working in the yard, were the plates flexing. It blew the face plate of the locomotive off and split the boiler from Stack to bell. The explosion was so loud that it created an 'Acoustic echo'. The explosion was not heard at the Willey Station, but at the Mount Willard Dwelling it was like a clap of thunder. The trees in the area were all blistered, Mr. Morse's watch was found in a tree, 20 feet off the ground. The water can that held water and a drinking cup was blown over a mile away. However, Mr. Morse's wooden lunch pail was found beside the engine, on a rock. This was a round pail with plates in it, not ONE plate was broken. Mr. Morse survived the explosion and being thrown 500 feet, he was found crawling towards a brook, all he said was, I know I'm done for, go check on Oscar. Oscar Clemons was trapped in the wreck, still alive. Both men made it to the hospital, both died at about the same time, 6 o clock that evening. Maine Central, not in its finest hour tried to sue Mrs. Morse for the loss of the equipment and damage. However in the court search it was found that 505 had received damage to its boiler, while in service in Baldwin Maine. Although not catastrophic, it did do some damage. It was also found that the 505 had been reported at least 5 times the previous month as having a leaky boiler, nothing was done. MeCRR dropped the suit, Mrs. Morse counter sued and won. The youngest surviving son of Oscar Clemons, now in his 80's commissioned a granite memorial to be placed near the site. It was put there several years ago. From a story penned by Bartlett, NH native Scotty Mallett based on firsthand accounts from families of those involved' (Pitts, 2008). 51Due作为专业的留学教育辅导机构,专业辅导essay代写-伯明翰assignment代写-paper代写-曼彻斯特论文代写,自2004年至今,坚持以学生为中心,全天候服务,为海外留学生完成了数万篇以上的论文,以优质的英国代写服务赢得留学生的信赖,有代写需求或者剑桥essay辅导、爱丁堡essay辅导需求的,可以咨询51Due哦。
