System Engineering: Amphibious Car

governance conducting Amphibious Car1 Statement of workIn 20th century, system locomotive engineer has been developed for human beings in night club satisfy their postulate in transportation services by implementing multipurpose vehicle. The aim of inventing amphibious gondolamobile is to lead on the track as well as operate in body of water as water vehicle.The objective of our team is to put up an energy efficient, environmentally friendly consumer vehicle which pile compete Richard Bransons record set in the Gibbs Aquada implemented on 2004.To develop the conceptual new geneproportionn of amphicar, the team has to query on the first generation stylel manufactured in 1961-1968. As described on the supra, to run down in performance as well as in energy efficiency, team need to be digested in the ideas of Gibbs Aquada.To meet the above requirements, amphicar should be assembled with jet engine using Supersonic Amphibious (SSA) engineering science to cast up the acce leration comp ar with the last generation. The vehicle go place commence the maximum capacity of 4 persons, which average body weight of 80KG. The amphicar should have token(prenominal) operation hour of 2 hours in the water.The expected project duration for the whole project allow be 30 days with reserved unity week for any delay. The project mess be divided into 4 major chapters, which are Systems Engineering Management Plan, System Requirement Specification, useful digest and Allocation and System Specification. Each chapter ordain have 2 days for preparation, 3 days for research and 2 days for final key out.2 cut back break overmatch structure2.1 Gantt Chart2.1.1 ScheduleFunctional Analysis Allocation2.2 CostNoNameBudget (US$)Expected Cost (US$)1 cat Plan20,00020,00021 Statement of Work1,00032 Work Breakdown Structure042.1 Schedule052.2 Cost062.3 carrefour Testing Method1,50073 Program Management2,50084 Risk Management2,50095 Resources Required2,500106 Deliverables 5,000117 Organization Structure0128 operative Concept5,00013System Requirements Specification20,00020,000149 Scope0159.1 System overview1,000169.2 Document overview2,0001710 Referenced Document2,0001811 Needs12,0001912 Requirements2,0002012.1 General Requirements1,5002112.2/3 Priority dining table Method Table5002212.4 System cleverness or Mode1,00023Functional Analysis and Allocation10,00010,0002413 Scope2,0002514 Referenced Documents1,0002615 Functional analysis2,5002716.1 Physical Overview2,0002816.2 Component exposits2,50029System test specializedation10,00010,00030Document overview2,00031Test detail8,00032Final system specification15,00015,00033Final analysis Documentation15,00034Miscellaneous5,0005,000Total cost for the whole project80,00080,0002.4 Product testing methodTesting is a kind of demonstration the abilities of the product in terms of performance characteristics, advantages and limitations that have been adequately determined for a specific purpose. Reliabilit y is an objective measurement of method reproducibility. If the test is not sufficiently reliable, that product is not qualified for using on intended purposes.In society to achieve the relevant outcomes of our amphicars objectives, there is slightly common stages of testing method impart be gone through as listed belowRisk judging Methods identify new methods in testing methods and strategiesResearch investigate mechanisms and other resources that groundwork be applied in tendency and test activitiesDevelopment carry strategies into standardized test methodsValidation make sure the accuracy and reproducibility are 100% grantedAcceptance determine acceptability for usersImplementation go over effective dashs of method for operators and users3 Program watchfulness suffer manager leave look after the entire project, call for meeting dickens times a week for steper checking and follow whenever issues arise during the period. Project engineer will work out on design specification to be developed and tested accordingly. Risk officer will report risk of infection resolution status to management team. Technical and sale engineers will control the tonicity assurances and serviceableity of entire project.Individual will have second plan for the case of emergency if first plan is failed to implement. Each and eachone will communicate and discuss the fortify of the project via phone, online instant messages and email.4 Risk management4.1 PurposeThis document describes how we perform the job of man senescence risk for Amphicar II project. It defines roles and responsibilities for participants in risk work ates, risk management activities that will be carried out, schedule and compute for risk management activities including any tools and technique that will be utilize.4.1.1 Project ManagerThe project manager will assign a Risk Officer to the project for identifying purposes on the projects organization chart. Project Manager, Risk Officer and a ll project engineers should have videoconference biweekly to appraise the status of the risk mitigation efforts, review the exposure assessments for any new risk items.4.1.2 Risk OfficerCoordination of risk identification and analysis activities, maintenance of the projects risk list, notification of project management of new risk items and submission of the report in risk resolution status to management.4.1.3 Project Engineers/Sale/Technical EngineerOfficer will assign each newly identified risk to a Project Engineer, who will assess the exposure and probability for the risk factor in and report the results of that analysis back to the Risk Officer. All Project Engineers are also responsible for performing the steps of the mitigation plan and reporting progress to the Risk Officer biweekly.4.2 Risk DocumentationRisk Identification1.

Man Power For individuals or organization, illness, death, resignation, personal matter.Lack of manpower could have caused the direct impact on the whole project progress, such as delaying on the deliverable of the project within given time.According to our Gantt chart, to decrease the impact or to sweep over for above risk, we have targets for each section to complete one day before the dead line and also as we have split up our project, everyone has to be submitted to the project manager advanced in two days before the dead line. So that, in case someone leaves in an unexpected condition, we quiesce have time slot to cope the job within the given time.2. Project Job tak ing too long, unable to complete within deadline. in that location could be many reasons for the delay. It is very of the essence(predicate) and we could face the liability for the delay period.To overcome this risk, we have reserved some tolerance period and fund. Keep snub on the project progress with the Gantt chart schedule.3. Financial After spending more on low priorities, there is not enough funds to complete the project.There are a lot of factors that could cause the financial over spent. The major cost consuming factors are labor cost during the test process to improve the functionality due to unexpected time delay and longer period to done the test. Improper budget plan may cause the project failure.To overcome the risk, we have allocated the budget accordingly and set aside some fund, so that in case of financial crisis or in the worst scenario, we still have some budget to work out. To minimize the test cost without jeopardizing the quality of the product, we implemen ted all the test procedure and specification carefully.4. System Failure Sever / PC down or crash.Equipment break down could cause the major issue as well. In the event of server or computer which important information stored was crashed or unable to operate, there will be a delay. We need to re-do all the work and it might cause project failure.To overcome and lessen the impact from this risk, everyone had kept their project information not only in the computer but also at away hard drive and finger drive. After sending out to project manager at the given date, the project manager had compiled all the individual work and saved it in his external hard drive as well.5. Communication Break Down Failure to pass down information.The breakdown in communication could cause the total desolation of the entire project. To overcome this risk, we have a schedule to meet one week 2 times, the first meeting of the week will be conducted by video conference.6. Technical Skills- Weakness of k nowledge in technical skill could prolong the employee is handling and maybe even impose the danger or upon to himself or the whole project. To overcome this risk, each one of us has to monitor closely and updates each other. Anyone finds out some important information on the wind vane or book that could improve our knowledge and skill for this project, we had to share by mail or scan the page and attach it.7. Procedure Failure of accountability, internal system and control.Failure of accountability, internal system and control could cause the whole organization structure collapsed.To lessen this risk, we had already implemented the role and responsibility for each one of us and organization chart. This will ensure each one of remain still on the track while doing project. Moreover by having limber organization chart (rotation of duty) will ensure that everyone is involved.8. Health Safety Injuries staff in the course of project.Health and synthetic rubber always has been the highest priority in every organization. Lacking of preventative requirement could cause paralyze the whole organization and goal.To overcome this risk, we had been oriented with safety requirement and regulation issued by WHS (Work place Safety and Health).9. Security Loss of data through unauthorized access.Loss of data through unauthorized access could have more than unexpected impact on the progress of the project.To overcome the risk, we had implemented all the security access code to our equipments and facility, which contains the informations of the entire project.10. Confidential Improper used of data by the staff.Improper used of confidential data may cause in leak aging of information to the third party as well as there can be bad reputation in Society.To lessen the risk, we had been brief all the staffs regarding about how to consequence precaution on this issue.4.5 Risk Assessment jeopardyRISK TYPEIMPACTLikely-hoodRisk levelCurrent controlMitigation optionsRisk owner Man powerDelay project long suit mediumAmberBack up man powerSet target earlier dateRisk OfficerOverrun dead lineFinancialMediumLowAmberClosely monitor with schedule time lineRisk OfficerOver spent on budgetProject failureHighLowAmberSet aside some fundRisk OfficerSystem Down motionalHighMediumOrangeBack up systemDepartment /TeamCommunication break downProject failureHighLowAmber twice a week meetingRisk OfficerLack of skill and knowledgeMay danger to otherMediumLowAmber overlap knowledgeRisk OfficerFailure of accountabilityOperationMediumLowAmberRole responsibilityRisk OfficerHealth safetySick or InjuryMediumLowAmberBrief on WHSRisk OfficerLack of securityOperationalMediumLowAmberImplement access codeRisk OfficerLeakage of confidentialOperational, FinancialHighLowAmberBrief on the die hardRisk Officer5 Resources requiredDefining the resource requirement is dividing the responsibilities of the people who involved. To do this, initially, listing roles and responsibilities for the project then start with the ideal way in which the project should be organized. It is often useful to refer back to the previous project that the people done before which kind of roles and responsibilities exhibited.Also review the resources available such as software, PCs, budgets limitation for the project and the individual member skill that they possess. Lastly, it is required to arrange the responsibilities, which is suited for every team member.6 DeliverablesThe projects are monitored from planning to operations. In accordance with the customers needs, wants and expectations, the project should have to plan towards delivering. The purposes are to complete on time, within budget, with the highest degree of quality, etc. Following are some facts of deliverables Procurement and Contract ManagementThe decisions are to be made including pickaxe of contractors and the types of contracts to be utilized.Executive SummaryThis should be a clear and concise digest of the current status of the project such as budget, schedule, quality etcProject Activities and DeliverablesThis is to highlight the deliverables occurring the previous month and planning for the next one to report in meeting, audits and other reviews, design packages submitted etc.Action Items/Outstanding IssuesThe action items/ outstanding issues may be dropped from this section upon full implementation of the remedial and upon no progress monitoring anticipated.Product QualityThe product is needed to plan corrective actions for deficient in quality.Internal and Stakeholder CommunicationsIt should have a discussion betwixt the internal members and stakeholder.Environmental MonitoringThe environmental permits may be obtained to specify additional requirements to be adhered.Safety and SecurityIn order to complete the project, safety and security is required for all individuals working.Traffic ManagementThis should be the requirement for providing monitoring and oversight of day-to-day maintenance of traffic operations.Project Communications (Media and macrocosm Information)A critical objective for the projects is to maintain the trust, support and confidence of the media and public throughout the project.Human Resources ManagementThis includes how roles and responsibilities for the project. Any other project functions that the project sponsors feel would be beneficial to include in the project Management Plan to ultimately help in meeting the project Objectives.7 Organisational structure7.1 Roles And righteousnessProject Manager will manage the entire project, assign right task to the right person, call up the meeting and always take commemorate of the deadline.Project Engineer will directly assist to project manager with majority in developing and testing the project.Sale Engineer shall have responsibilities of marketing, budget control, banking and purchasing.Technical Engineer manages the technical part and specification of the project.Risk Officer will maintain the proje cts risk list, safety and security of the entire project.8 Operational ConceptThe project is about the design of the Amphicar-II which is the amphibious vehicle and able to operate as a recreational water vehicle and travel on the land. The aim of the project is to produce an energy efficient, environmentally friendly consumer vehicle and crossbreedingizing in the English Channel to beat the record of Richard Branson set in the Gibbs Aquada (2004).General description of the projectThe project carried into 4 parts.a. Draft systems engineering management plan (SEMP)b. Draft system requirement specification (SRS)c. Draft functional analysis and allocation (FAA)d. Final system specification (SS)Before we start the project, we formed the organizational group. Then we analyzed the work breakdown structure, such as schedule, cost and product testing method. First, we drew the gantt chat for schedule and estimated the cost. Then, we analyzed the program and risk management and defined res ources and types of deliverables.In the second stage, we defined needs and system requirement specifications. The needs include able to travel on road and water, environmentally friendly, energy efficient and cross the English Channel to beat Gibbs Aquada. The requirements are general, safety, user, environmental, security and privacy and legal requirements.In the third stage, we sketched the functional analysis and allocation. We used the core software to produce the diagram. We sketched the physical designs and write the ingredient details and matched them. And we drew the flow chart to analyze the system.In the final stage, we performed the system testing and summarized the project. And, we made the modification according to the test result. Then, we prepared the report and handover to the customer.System Requirements Specification (SRS)9 ScopeThe aim of amphicar-II project is to produce an energy efficient, environmentally friendly consumer vehicle that is capable of travelling on road and operating as a recreational water vehicle. Moreover to introduce the vehicle to public, the first prototype will be used in crossing in the English Channel, beating Richard Bransons record set in the Gibbs Aquada.After years of on the road development, amphibious cars start to introduce to the public which can travel not only on the land also on the water. In this project, we are trying to pursue the new technologies to provide better innovative, efficient, affordable options for daily life. To concern about this, below will briefly describe what the system all about is according to purpose, operation and maintenance.9.1 System Overview9.1.1 Vehicle On The RoadHybrid systemHybrid means any vehicle that combines two or more sources of power that can directly or indirectly provide propulsion power. 7 It uses the rechargeable energy storage system and uses as power source to drive the vehicle. As concerns increase over global warming, hybrid uses less raise and causes le ss pollution to environment as well as easy mode of transportation and lessening.Operation of hybrid system with engineAccording to our needs, we should be using gun-electric Hybrid Structure that can compatible to our aims. This structure includes the following parts to operate as hybrid systemGasoline engine the gasoline engine using in our Amphicar II project will be smaller than other normal car engines but it can help to reduce emissions and increase efficiencyFuel tank the fuel tank in a hybrid acts as an energy storage machination for gasoline engineElectric motor the technology of electric motor using at hybrid system is very advance and can be used not only as a motor also as a generator to supply power source to engine. Electric motor can pull energy from the batteries as well as will recharge again while the vehicle is moving.Generator the generator only produce electric power to the engineBatteries the batteries are the energy storage devices for the electric moto r in a hybrid car.As for energy efficiency and environmentally friendly, we have choose to use hybrid technology engine for our amphicar-II. Hybrid system is the wave of the future and there is more incentive to purchase one.In our conceptual design for land, the standard production model of Amphicar II will be sport car design and power by larger V-6 engine and more powerful electric motor, with the combination of the concept of plug-in hybrid that will able to go from zero to 62 miles per hour (100 kilometers per hour) in 3.5 sec and will has a top fixity of 187miles per hour (301 kilometer per hours) with CVTs continuously variable transmission 5 speed manual high performance close ratio transmission. It will be the first ever its kind of in amphibian car, which can able to deliver the performance of sport car with maximum fuel efficiency.The vehicle type will be front engine, front wheel drive with 3.73-1 axle ratio, 2- accesss, 4-passengers, convertible top, fitted with four w heel independent suspension and brake with untainted steel rotor. The amphicar-II will be approximately weighs 3,300lbs(1500 kg) and the weigh will be split up 53-47%, with 53% on the drive tires on the front9.1.1.1 OperationThe controls and operation will be completely carlike on the land. On water the accelerator can be use as a throttle and the counsel remains as the same.9.1.1.2 Vehicle StyleThe styling of the amphicar-II body structure will be look a bit like Lamborghini. The dimension of the vehicle is 4 meter in length, 2 meter in width and 1.5 meter in height.9.1.1.3 General Feature Of The VehicleThere will be climate-control system, 4- ambiance bags, tachometer, drivers passengers electric seat, drivers seat memory, speedometer for land and water, cruise control mode, oil pressure, engine temperature, voltage meter, gasoline fume detector, bilge ventilation blower, compass, clock, navigation (GPS), auto pilot system in water mode and AM/FM stereo.9.1.2 Vehicle On Water Jet EngineTo provide faster speed with better performance, we decided to use jet engine with lightweight and compact design while driving on the water. Though there are dissimilar types with varies sizes in jet engines, the technology used in jet engine is all the same. The fact is they depend on the high-pressure column of water pushed out of the engine to propel the boat.To travel on the water our Amphicar-II will be power by Berkeley Marine Jet with power trim package and it will has capable of speed up to 40mph (65 km/h) on water. It will able to pull a water skier easily. The Berkeley Marine jet will be design to be lighter and more compact. It will have half a length and one-third the weight, compare to most other water jet. The impeller will be installing and contain inside the body of the jet, therefore it will be very safe for swimmers. The amphicar-II will have a low speed reversing cogency by running the water jet in reverse direction. The guidance will be mounted on t he back of the stator nozzle and will connect to the car steering wheel.9.1.2.1 Main Body MaterialsAnother great thing about this amphicar-II will be durable and attractive. The lower part of the amphicar-II will be lightweight component the 5052-alloy aluminum single piece hull. The upper part of the amphicar-II body will use lightweight fiberglass to minimize the general weight of the amphicar-II.9.1.2.2 Feature On The Lower Part Of The BodyThe hull will be design to be aerodynamic in road mode and hydrodynamic in water mode. It will provide over 1750kg of hydrodynamic lift. It will also provide a stable planning surface allowing the amphicar-II to grate/plane over the surface of the water when given sufficient from the jet. The hull will have a keel fin that will give s directional stability and provide grip for high speed handling performance on water. There will be a spray rails and chin either side of the body, it will prevent the water spray to the cockpit and ensure the oc cupants remain dry. Also it will provide grip to give surpassing maneuverability.9.1.2.3 Special FeatureThe hull will be pack with floatation foam and the amphicar-II will not sink if it knocked at the bottom part of the body. It will only float on the water in the worst scenario, but it would not sink.9.1.2.4 Special Feature Of SuspensionThis amphicar-II will have retractable 4 points independent front and rear suspension system. By retracting its four wheels up to within the wheels housing, it will prevent from the wheel dragging to the water and will increase its water performance, and better manoeuvre ability. Also it will automatically decouple when the engine no longer drives them. The hydraulic rams that move the control arm suspend corner up and down, also serve as automatic ride height control.9.1.3 Mode TransitionThere will be mode selection switch, to change either water mode or land mode. The mode selection switch will interlock with water sensor, to prevent from changi ng to water mode while driving on the road. So that to change from land to water mode, the water sensor has to detect enough water depth in order to retract the four wheels. The switch will also have a cover to prevent from accidentally switching of mode select switch.By pressing the mode selector button to marine mode, it will drops the clutch, disengages the road drive, shifts the transmission into aquatic duty, retract the wheels, the jet drive kick in and take off in water. All this process will take place within 10 sec.The retraction of the wheel will be as same as what AQUADA used but only difference is that the wheels are retracted upwardly and aluminum plates will be occupied firmly without leak aging at the place of the wheels. So the entire Amphicar looks like totally as a boat floating on the water surface confidently. In order to prevent leaks, this Amphicar-II has covered with a single frame using aluminum metal.9.1.4 PerformanceIt will be like a sport car on the road a nd speedboat on the water.9.1.5 MaintenanceFrequent hull inspections at panel seams and joints are essential. The user should check and clean after cruising in salt or brackish water is a thorough hosing with fresh water for the entire hull and all exposed suspension and nautical propulsion components.Items need to be check by service engineers are lists down below,1.
