IT Management Issues for Public Transportation -myassignmenthelp

Question: Discuss about theIT Management Issues for Public Transportation. Answer: Introduction Bid Taxi is a service that has been proposed in order to improve the ride sharing services for the passenger. As a replacement of the existing system of offering services in a fixed rate, the Bid Taxi makes use of bidding service for a ride. For availing the Bid Taxi services, customers will have to state the beginning and end point of the journey, the number of passengers who will be availing the service and the time for pick up. These data will be broadcasted to all the drivers or driver providers, and the interested driver provider will bid for the service (Lucas Lau, 2012). Customers can therefore choose from the available bidding options. This therefore improves the process of booking the ride. Customers will be able to able to track the responses of the drivers in real time. Apart from this, the whole journey will be tracked with the help of a GPS system. The report discusses the working principle and the business operation of Bid Taxi and recommends certain improvement in the services as well. The business operation of Bid taxi is discussed in the following section. Business Operation In order to provide a hassle free service to the passengers, the Ministry of Public Transportation has set up certain business goals that give an overview of the business operation of Ministry of Public Transportation. The business operation of Ministry of Public Transportation is as follows- The Bid Taxi services provides an option of making and online booking of the taxi services in the lowest price possible. This is definitely an intelligent business operation as undertaken by Ministry of Public Transportation as the ease of booking offered by Bid taxi is expected to increase the customers engagement with the services. Bid Taxi on boards only the certified drivers for offering their services. Furthermore, the vehicles are thoroughly checked as well in order to verify whether the vehicle has insurance or not (Lu et al., 2016). This is an important business operation of Ministry of Public Transportation as it assures the passengers that premium services are provided to the customers. The booking of the taxi services can be done online with the help of the smartphone application or with the help of the website of Bid Taxi. Majority of the people now a day have an access to Smartphones and internet and therefore, it would not be difficult to book the services offered by Bid Taxi (Bai et al., 2014). Apart from the application, the Bid taxi services can be booked with the help of the website as well. This enhances the process of Taxi booking and therefore, is expected to increase the customers engagement with the services. The payment option for the Bid Taxi services has been simplified as well. The passengers availing the Bid taxi Service can make their payment through credit or debit card services. Furthermore, the Osko payment application can be used as well in making the payment. The payment received from the Osko payment services will be help by the Bid taxi Office. The passengers who do not have an access to any of the payment method can make use of the gift cards purchased from the supermarkets. Providing an option for secure payment services is expected to draw more customers in availing the service, thus increasing the profit margin of the Ministry of Public Transportation (Weng et al., 2017). This is therefore an important business operation of Ministry of Public Transportation. With a view to encourage the customers in availing the Bid Taxi Services, Ministry of Public Transportation has introduced a service loyalty program. In this program, the passengers who are paying for the Bid Taxi service are given status points for the rides paid. These points can be used by the passengers in their next ride as a discount, can be given as a tip to the drivers or can be donated in charity (Pueboobpaphan, Indra-Payoong Pueboobpaphan, 2018). It is an intelligent business operation as the passenger who had paid for the Bid taxi Service once, will avail the services once again. This will improve the customers engagement with the services as well. A Star rating system has been incorporated in the bid taxi services as well. In this rating system, the customer and the driver are able to rate each other. A customer rates a driver on basis of the services provided while a driver can rate a customer on basis of the co operation offered by the customer while availing the services of Bid Taxi. According to those rating, the Ministry of public transportation will be able to modify certain services provided to the customers. This includes removal of the driver or driver provider from service, who is rated bad consecutively for the rides offered. The rating on the customers will further help the ministry of public transportation in understanding which customers are offering full co operation to this service (Wang, Cheu Lee, 2014). This feedback can be used to provide additional benefits to the passengers who are rated highest in the list by the drivers. Presence of this star rating system is therefore an important business operation pr ovided by the ministry of public transportation. Not only the customers who are rewarded for the services offered by the Bid Taxi, the drivers are also rewarded for providing excellent services to the clients. The driver providers on completing a pre set timely targets are rewarded with a fuel discount gift cards by the company. This in turn encourages more driver providers in offering services to Bid Taxi. The points give an overview of the business operation of the Ministry of Public Transportation. Bid Taxi is capable of revolutionizing the way of providing sharing rides to the passengers across the country (Agussurja Lau, 2012). The business operation of Ministry of Public Transportation can be further improved by modifying the certain existing operation and the services of Bid taxi. The recommendations for improving the business operation of Ministry of Public transportation are as follows- Along with the start rating system, it is recommended for the Ministry of Public Transportation to provide a feedback system to the customers and the drivers as well. The feedback system will enable the customers in providing a public review to the services availed. Furthermore, since the reviews of the customers and the drivers will be posted in the public platform, it will enable the new passengers in having a complete understanding of the services that will be offered by Bid Taxi (Kumar Kumar, 2016). The Ministry of Public Transportation will furthermore be able to improve the services according to the customers demand. The feedback system is expected to act as an intelligent marketing tool as well, since the positive reviews will surely encourage more passengers in availing the Bid taxi services. The Bid Taxi generally offers the ride sharing services across the city. One addition to the service might be offering services for a long distance journey like he tour travel services. This is expected to improve the customers engagement with this service (Zike, 2012). Offering the tours and travel services to the client can therefore be a suggested addition in the business operation. With the help of this service, the clients of Bid taxi will be able to avail a cost effective taxi service for short journeys as well. Another recommendation to the services and business operation of Ministry of Public Transportation is that the bidding time can be considerably reduced in order to provide services to the passengers who are in a hurry. The option of pre booking a particular ride should be present as well in order to avail the service just in time when it is required the most (Billhardt et al., 2015). Reduction in the bidding time is necessary to provide quick services to the clients. The presence of the pre booking services is expected to improve the customers engagement with the business as well. A pre booking charge can be levied from the passengers who are using the service for the first time (Wang Cheu, 2013). However, in order to increase the customers engagement, it pre booking charges can be dropped for the regular customers. The above recommendation suggests some critical modification that can be infused in the existing operation of Bid Taxi (Chen, 2014). These suggestions are expected to improve the business operation of Ministry of Public Transportation in terms of profit and customers engagement of with the service. Conclusion Bid taxi is capable of revolutionizing the process of taxi sharing, offering a cost effective option to the clients in availing a paid taxi service. The report provides an overview of the entire business operation of Ministry of Public Transportation. The business operation of Bid taxi is aligned with the business goals identified for the project. The report further recommends certain modification in the services offered and the business operation of the company. Proper modification of current business operation is expected to work in favour of the company and in favour of the customers as well. The business operation of Bid Taxi is aligned with the certain business goals identified for the project. The business operations are so designed keeping in mind the requirements of the customers and with an aim of customer retention by increasing customer satisfaction. However, the service of the Bid Taxi can be improved by bringing in certain modification in the normal operation of Bid taxi. The recommendations for improving the Bid taxi services are as follows- Driver training can be an important addition to the current services of Bid Taxi. Bid Taxi takes on board only the certified drivers. A training program may improve the possibility of engagement of more drivers in offering their service to Bid Taxi. A driver who is willingly to offer services to Bid Taxi will have to attend this training as a mandatory requirement. This is expected to increase the customers trust as well. Not only for driving, the driver and the driver providers are needed to be trained about the use of the Bid taxi application, the star rating system and the reward programs (Chen, 2014). The training program will therefore improve the skills of the drivers thus providing them more job opportunities in future. Taking trained drivers on board will provide a sense of security to the business as well. The passengers will definitely prefer trained drivers and therefore the company is expected to offer the training services to the drivers. Customers safety should be an important consideration for the Bid taxi services. The application should incorporate an option for reporting a service or an issue if a customer faces any such problem. The entire journey of the Bid Taxi will be tracked with the help of GPS and therefore it may not be a problem for the companies to the send help to the passengers in time of need (Weng et al., 2017). Therefore, presence of a report button in the application can help the passengers in availing emergency services. The report button can be used for reporting certain other cases such as uncomfortable ride, long waiting time and so on. These are the two major recommendations for improving the business operation of Bid Taxi. The business operation of Bid taxi is designed in order to provide a hassle free taxi booking service to the clients. The operation of Bid Taxi is expected to enhance the ride sharing experience of the customers. Apart from the ease of booking, Bid Taxi provides a secure option for making the payment for the ride, which is a major advantage of this service (Debnath et al., 2014). With the certain modifications that have been proposed, the Bid taxi is expected to target a larger base of passengers who need to avail Taxi services more often. The online taxi booking service is expected to enhance and revolutionize the existing ride sharing service. References Agussurja, L., Lau, H. C. (2012).

The aim of this investigation is to find out how different lengths of a 1m long nichrome wire affect its resistance Essay Example

The aim of this investigation is to find out how different lengths of a 1m long nichrome wire affect its resistance Essay I predict that if I double the length of the nichrome wire, its resistance will also double. I predict that if I half the length of the nichrome wire, the resistance will also half. Therefore I predict that resistance will increase in proportion to the increase in the length of the wire.HYPOTHESISWhy does a metal conduct?A metal is made up of positive ions surrounded by a sea of free electrons. The ions in a metal are positive because it is easy for a metal to lose one or two electrons, from its outer shell, than to gain six or seven electrons to complete the outer shell. The electrons are lost and are free to move around and the ions become positive as the number of protons increase, compared to the number of electrons. The metal can now conduct electricity, as it is positive.Here is a diagram to show the structure of a metal:What is resistance?Resistance is the measure of how difficult it is for the current to get through a wire. We measure the resistance in Ohms, with the symbolRe sistance, R = p.d. across the wire (V)___Current through the wire (I)R = VIWhat causes the resistance in a wire?The electrons in a wire are free to move through it, but it is not perfectly easy. The ions of the wire get in the way. The electrons collide with the ions and get slowed down. So a single electron will make a stop/start journey along the wire as it bumps into ions. The piece of wire has resistance because the ions restrict or resist the flow of electrons.Ohms Law states that, The current flowing through a metal wire is proportional to the potential difference across it. (Providing the temperature remains constant.) Proportional means that if you double the p.d. the current is doubled. Therefore the current is inversely proportional to the resistance. Whatever we do to the resistance, it changes the current by one over the number.Voltage =Current*Resistance I.RResistance =Voltage R = VCurrent ICurrent =___1____ I 1Resistance RThis supports my prediction that if I double t he length of the wire, the resistance will also double and if I half the length of the wire, the resistance will also half as I am going to change the length of a wire while carrying out this investigation.Resistance restricts the amount of current flowing through a wire and therefore slows down any reaction, which it supports. Resistance also plays a good part as it stops things from blowing. It stops too much current from getting through, which can blow or damage an appliance.Four factors affecting resistance are:1. As the length increases, the resistance increases. This happens because if the length of a wire is increased the electrons will have to pass through more ions without colliding. That rarely occurs and resistance increases as they collide. This can affect the results of my experiment as I have to decrease the length of wire in my experiment and if I make an error in decreasing the length, it can change the results of the whole investigation.2. As cross-sectional area in creases, the resistance decreases. This is true because, if there is more cross-sectional area for the electrons to flow in, there is a better chance that they will get through without colliding. As a result resistance will decrease. This will not affect my investigation, as I will be using the same cross-sectional area of wire throughout the investigation.3. Only good conductors are used for connecting wires. Good conductors such as copper are used to connect wires as they have got a low resistance and will allow more current to flow through them. Very good conductors such as gold improve the quality of output of an electric appliance. The wire, which I am using in the experiment, is nichrome, which is a good conductor.4. As temperature increases, the resistance of a wire increases. As the temperature is increased the ions vibrate more vigorously, colliding with electrons, which are moving through the wire, producing heat energy. The increasing temperature favours more collisions, and the collisions restrict the amount of current flowing through. Therefore resistance increases. This factor will not affect the investigation, as I will be doing the investigation at room temperature.The length of a wire affects resistance because:In theory I conclude that the smaller the wire, the less resistant it is. The bigger the wire the more resistant it is. This also supports my prediction that if I double the length of a wire the resistance will also double.Apparatus required:; Power supply 0-12V (dc); 1 m nichrome wire; Ammeter; Voltmeter; Connection wire; Metre rule; Crocodile clipsHere is a circuit diagram for the experiment I am going to carry out:VariablesIndependent variables are the factors that I will change during the experiment. In my Investigation the independent variables are:; Length of wire in cm; VoltageDependant variables are the factors that depend on the independent variables. In the investigation the dependant variables are:; Resistance; Current; TimeC ontrol variables are the factors that must stay the same to make it a fair test. The control variables are:; Temperature; Type of material (wire); Thickness or cross-sectional area of wire.I must keep all the control variables the same throughout, as they will all restrict the amount of current flowing through, if changed during the experiment. Therefore they will all increase the amount of resistance and I wont be able to obtain accurate results.Method; I will set up the apparatus as shown in my circuit diagram above on page 3.; I will decrease the length and increase the voltage as I carry out my experiment. The range of measurements in my investigation are as follows:100cm-20cm this measurements are reduced in 10cm intervals and I will take 9 readings. I am only bringing down the length of the wire to 20cm so as to avoid over heating of the short wire in a high voltage.The voltage is increased from 2volts to 8volts in 2-volt intervals. Therefore I will take 4 readings for each me asurement. The limit in the investigation is 8 volts so as to avoid over heating and burning the wire. If the voltage were higher than 8 volts for this type of wire, then it would burn the wire and ruin the whole investigation.; I will then record the current readings obtained and find the Resistance using the formula: R=VI; I will then find the average resistance by dividing the total resistance of all 4 different volts by 4.In my investigation I will have to cool the wire after increasing the voltage each tine so as to obtain accurate results. High voltage can also burn the wire so I will have to cool the wire for safety reasons.High voltage increases the temperature in a wire and therefore also causes more resistance because the ions and electrons gain more energy and vibrate more vigorously causing collisions, hence more resistance as the electrons are blocked from reaching their destination.I will repeat the whole experiment once again to make my results as accurate as possible .SafetyWhile doing the investigation, it is important to keep safety into consideration. The scissors should only be used for cutting the wire to the appropriate length and for no other reason. Before using the power pack, the pointer should point at 0 volts. It is important to be careful while using the power supply. While handling live wires, it is essential to be careful. The voltage should be kept low because of the safety factor and the wires heating up.OBTAININGResults table 1 showing the readings obtained after carrying out the experiment.Length (cm)Voltage (V)Current (A)Resistance ( )Average Resistance ( )10020.623.2341.253.173.1861.93.1682.543.159020.692.941.382.92.8962.092.8782.82.868020.772.641.552.582.5762.352.5583.142.557020.872.341.762.272.2762.662.2683.582.236021.011.9842.051.951.9563.11.9484.151.935021.211.6542.451.631.6463.681.6384.91.634021.471.36431.331.3464.521.3385.991.343021.841.0943.831.041.0665.731.0587.611.052022.740.7445.520.750.74680.72810.750.74I used the formula R=V to calculate the resistance.ITo calculate the average resistance I added up the resistance for each measurement and divided the total by 4.Results table 2 showing the readings obtained after carrying out the experiment.Length (cm)Voltage (V)Current (A)Resistance ( )Average Resistance ( )10020.693.393.3941.183.3961.753.4382.583.369020.663.033.0341.823.0361.993.0282.643.038020.712.822.7641.462.7462.182.7582.932.737020.842.382.4141.662.4162.482.4283.322.416020.922.172.1141.912.0962.872.0983.832.095021.161.721.7442.291.7563.441.7484.551.764021.291.551.542.661.564.061.1885.511.453021.691.181.1743.431.1765.141.1786.891.162022.280.880.8644.720.8567.10.8589.20.87AnalysingHere are the graphs showing the results from the result tables.Overall the investigation, I carried out went quite well and my results are also fairly accurate.For example in my first result table, when the length of the wire was 50cm the average resistance was 1.64 . When I doubled the length to 100cm the aver age resistance also almost doubled to 3.18In the second table, when the length of the wire was 20cm the average resistance was 0.86 . When I doubled the length to 40cm the average resistance also almost doubled to 1.50. My graph of average results also shows that all the points are almost in the line of best fit. This also proves that if I double the length of a wire the resistance will also double.This shows the evidence that the resistance is directly proportional to the length of a wire. Directly proportional means when a substance doubles the other substance also doubles. The evidence I found also backs my prediction that if I double the length of a nichrome wire, its resistance will also double. The resistance will double because the ions will restrict or resist the flow of electrons and therefore creating resistance as a result of collisions between the ions and the electrons.EvaluationAfter carrying out the full investigation I can say that my results are quite reliable and a gree with my prediction that I made.Overall there were no anomalous results in my investigation as you can see from my graphs, but my results are not also perfect as in my theoretical prediction. Errors may have occurred while I was doing the experiment.Here are the errors, which may have occurred while I was doing the experiment. There are two types of errors namely:; Systematic error-this is the type of error due to the fault in a measuring device.; Random error-this is the type of error due to human mistakes.Systematic errors in my investigation are:; The ammeters and the voltmeters were probably faulty and I could not get the accurate results.; The power pack might have malfunctioned and might have ruined whole of the voltage supply.; The scale of the metre rule I used was not marked according to scale and that affected in the accuracy of my results.The random errors:; I might have made a mistake while recording the results. E.g. instead of recording 3.06 I might have recorded 3 .66; I might have cut the wire a little longer or a little shorter while cutting it.Due to all these errors the accuracy of my results might have been brought down while doing the investigation.The ways that I could improve this method to get more reliable data are:; Using computer controlled ammeters and voltmeters to detect any faults n them.; Use a more reliable power pack then the one I used in the investigation.; Use a different piece of wire for each length so as to prevent over heating of the wire.; Use a digital ruler to measure the different lengths of wire to prevent the measuring error.These are the ways, which I came across in order to get more reliable and precise results.Further experiments that I can do to investigate this topic are:; Measuring the resistance in a bulb using different volts; Measuring the amount of resistance in metals such as copper, with different masses.Doing these experiments will further prove my results more reliable and back the theory of resis tance.
