System Engineering Assignment On Design and Function Analysis

Introduction:
The main objective of this system engineering assignment is to transform the interface, functionality and some other demands, which is identified by the process of requirement analysis into the function description of the system. This is used to manage and monitor the activity of the synthesis design. The function arrangements and decomposition of the function from a high level to a low level and performance of duty can define the above thing. The analysis of the timeline and the flow block diagram is included in the tools, which is used in this (Chapman, 2018). The result of the design synthesis is the solution of the requirements, which is correctly done by the functional analysis and allocation. The function is used to identify the objective of the system. The elements can derive them, or they might be explicitly described. The function is the central part of designing the operation of any organization.

The process overview of the functional analysis and allocation:
From the requirements of the higher level, the functionality and the performance of the elements are developed in any level of the system. To define the function of the lower level and requirement of the function, successively is repeated by the functional analysis and allocation (Bahr, 2018). To provide the verification of the system and the design of the system, the requirements of the system is allocated, and this is used to support the integrated design of the system. Here the process of design is as follows.
  • At first, make the function according to the system and then decompose the function into small sub function.
  • The requirement performance of the high level is translated into the design criteria’s performance. This is describing the performance of the function.
  • Internal and external interfaces of the function are identified
  • All characteristics of the function are determined and co-operated them into the process of function analysis and allocation.
  • Examine the life cycle of the function and include some primary function, which is needed for the project.
  • Arrange the alternative function to fulfil the requirements and again revise the whole process to solve the problem with the functional risk.

  • Inputs: the input of the functional analyzing and allocation is the result of the analysis of the requirements process.

    Outputs: the outputs are the details of function architecture and the details of the architecture.

    Supporting process: some models like QFD, diagram of block flow, IDEF, chart of N2 etc. some organizational inbuilt process is used.

The function analysis approaches/ methods:
The function is called the interaction between the input and output. In another word, the function is called the duty of the product that it is capable of doing that. To solve the design problem, some service is used, and function is made according to the design of the system (Chapman, 2018). The function does not depend upon the solution, and it consists of the input and output, which is used to solve any design problem of the system. The function establishes the relationship between the input and output. There are some methodologies of the function analysis in system engineering. The first step of the method is to identify the physical components from the starting point or the top level. The identifying product is used in future to produce the future product. The analysis of function is applied in every level of the design, sub level and the system of the system. The total methodology of the function analysis process is shown in the Fig1of this system engineering assignment. It also shows the tasks, relationship between each job and lastly the input and output of the job. The functions of the functional analysis are listed below:
  • Tree of the function
  • Matrix of the function components
  • Tree of product
  • Relationship matrix
  • Block diagram of function

The function tree is generated at the first step of the analysis process of the function based on the requirements of the system (Garvey, Book and Covert, 2016). After generating the functional tree, the component matrix of the function is created and is identified the basic component for the product tree. After identifying the necessary ingredients, the product tree and the relation or connection matrix both are built successfully. Now with the help of the product tree and the relation matrix, the final functional block diagram can be drawn. Useful tree, a matrix of the function and the tree of the product is the core part of the functional analysis. Mainly, with the help of identified components and the requirement the future product will be generated. To determine the future product, product tree is used (Morse et al., 2018.). When the connection and relationship between each task is identified, then the architecture of the future product is wholly done. The primary output of the function analysis process is the function tree and the tree of product. The secondary production of the functional analysis is the diagram of the functional block.

The function allocation approaches/ methods:
In the allocation of the function approach, the main thing is to use the FAR approach the output of the distribution of the function is generated, and a use case model shows the actual output using this FAR approach (McKean, 2019). The use case model is used to define all use case, which is analyzed from the system. FAR produces the function breaks down structure, description of the functional architecture and the sheet of requirements allocation. The input of the activity of flow down is the FAD and RAS. The information now changes as the output of the different system’s requirement specification.

The function breaks down structure: the functional break down structure provides the complete functionality of the system and the complete overview. The system provided a group of function is included in the functional break down structure. This added function is the primary function served by the requirements of the system.

Survey of use case model: the main objective of this system engineering assignment is to give the whole concept of the every use case, which is present in the model.

Specification of the use case: the specification consists of the precondition, postcondition and the context information. This information is the introduction of the specification. It defines the black box scenario that means the relationship between the system and the user is described by the use case specification (Mensah, Kakaï and Seifert, 2016). Use case model shows the fragments of scenario and by using this scenario reach to the scene of success. The primary step is to identify the proper position of situation based on the pieces. Fragments are inserted place, which is suitable for the fragments. The result of the fragment may be generating a success scenario, or it closes the use case. The following steps are the scenario of the black box.

Step1: when the customer provides a general id, then the use case is started. After accepting a public id from the customer, a unique identifier is requested from the customer. It requires 1 sec response time to do this step.

Step2: in step 2, the customer or user provides the unique id, and the system accepts the id. The system creates a platform to check the validity of the general id and the unique id. The maximum response time of this step is 0.5sec

Step3: if the generated identifier is valid, the system provides services as per the requirements and then use case is finished. It also requires 0.5sec.

If the unique id is not valid, then the system gives an error message to the customer and suggests generating a new unique identifier. Then the use case again continues with the normal process.
If both the unique id and general id are invalid, then the system generates some error message after accepting the public id.

Description of functional architecture: the technical architecture description includes the realization of all use case of the system (Smith et al.,2019). The collaboration of all the subsystem and representation of how they solve a specific task with excellent communication is called the realization of the use case. In the other hand, it is known as white box description of the use case. Each black box steps of the use case is decomposed into several numbers of white box steps. Here discuss the step of the white box where shown the collaboration of every subsystem.
After accepting the authentication result from the validation of the unique id then the card reader captures the general id (Gore, 2016). If there is any error, then transaction control gives an error message with the help of output devices. Then the error message is presented to the customer by the output devices.

The sheet of requirements allocation: there are two purposes for the requirements allocation sheet. The first one is that it manages the overall system between the use case and the needs of the system. The second one is that it is used to allocate some not suitable requirements for the use case. It is tough for the use case to handle the conditions, which is non-functional.
Requirements of the subsystem: the primary responsibility is to specify all elements of the subsystem. This is the primary work for the domain engineers. The system engineer is used to ensure that the result of the requirements of the sub system is presented in the original order and ensure their allocation. More than one subsystem requirements are resulted in the analysis of FAD and RAS.

Conclusion
It is concluded from this system engineering assignment that the function analysis and allocation is an essential part of the system engineering. With the help function, the designing of any system is possible. The service creates some relationship between the input and output. To solve the design problem, some function is used and function is made according to the design of the system. The function does not depend upon the solution, and it consists of the input and output, which is used to solve any design problem of the system (Krarti, 2016).To develop the design of the system the function is designed. According to the behaviour of the system design, the function is generated. Use case model shows the fragments of scenario and by using this scenario reach to the scene of success. The collaboration of all the subsystem and representation of how they solve a specific task with excellent communication is called the realization of the use case. The first part of the system engineering assignment shows the method of function analysis. Here using some steps like the functional tree, requirements tree, tree of the product, then making the relationship matrix for this and lastly, draw a function block diagram to analyze the function. Then the step is to discuss the allocation method of the service. In this step use some use case model, function break down structure, specification of use case model, black box description of use case, white box description of use case, then make functional architecture description maintain the allocation sheet and lastly discuss the requirements of the subsystem. Here to generate the success scenario, many fragments are used. The best performance is managed by the FAR approach based on the needs of the company. This study is also used in system engineering, software engineering and electrical engineering. This is used in some pilot project in future (Hui et al., 2015). This will help to describe all the functionality of the system. But there may be a problem of identifying the best possible use case and make all types of description of the use case. Here methodological support is necessary for this approach. So functional analysis is starting with identifying the physical components of the high level and then decomposed them into the lower level. After completing the decomposition of the requirements of the function, individual allocation is performed at the lower level. Then showing the allocation process of the lower level then combined all the result of that level and passes it to the higher level to produce the final scenario and then the improved design of the system is done. In other word, the function is the interface between the requirements of the system and then according to the conditions they design the system correctly. System engineering assignments are being prepared by our engineering assignment help experts from top universities which let us to provide you a reliable assignment help online service.

System Design Assignment: Smart Trolley


Introduction
            The supermarkets and malls have been the most populated offline stores where there is always a problem for lots of consumers to stand in a queue for making the payment and thus, they have to spend more time for just making the payment. It was identified in the previous work that this could be a vital problem for the consumers availing the offline services at the supermarkets and the malls. The proposition of a smart trolley can be the possible answer for this identified problem that can meet the consumers satisfactory level and minimizing the workloads of the supermarket staffs. It can be described as the smart tool or device that will calculate and record all the data related to the products being purchased and related details. The designed smart trolley will also allow the individuals to look at a display that will be demonstrating all the product information. The proposed tool will be much efficient and effective than an individual specially assigned at the billing counter and will be helpful in eliminating the expenses of the supermarkets and malls by providing them effortless and fast services.
 The proposed system design assignment will be helpful enough for the management of staff-less payment services and eliminating the extra need of the queue in which the customer might have to stand for a long period. The concept of this smart trolley was comprised of the electronic devices such as RFID, ARM7LPC2148, screen display, and ZIGBEE. The ARM7LPC2148microcontroller will be installed for the management of the entire operation and operational data. The proposed system design assignment would be capable enough in reducing the expenses of the supermarkets and the malls and allowing consumers to avail the best service with much-enhanced production and output.
            The purpose of this system design assignment is to demonstrate the preliminary design proposed for the project and thereafter, explain the detailed design that can be helpful in demonstrating how the project will function in the real life. An evaluation report has been also proposed in this report explaining the efficiency of the proposed project for the supermarkets and the malls.

Preliminary Design

The proposed design of the smart trolley in this system design assignment will be acting as a small database and payment system that will ensure that the products being collected in it is being recorded. This could also be represented as a small information system that will be collecting and processing the data and information related to the products and their amount. It is being assumed that all the products will be tagged using RFID and every user will scan RFID tagging while carrying it in the trolley. After processing the product scan the microcontroller ARM7LPC2148 will record the related data and process it within the embedded processing unit (Ali and Sokusare 2014). The product scanner will provide the necessary details to the display where all the products and their details will be shown along with the taxes and the product cost. Thus, the entire process of billing will be automated and the user can see the actual price of the bucket and pay accordingly. This will allow in the fulfillment of the project scope that was to eliminate the need of extra hand for the payment at the billing counter and stay in line for a longer time. The payment processing system will consume much less time than it was taking in the traditional system.

Detailed Design and development

Object Tracking

            The embedded object tracking will be scanning the products RFID tag and searching the database for the product details, cost, discount and thereafter the data will be embedded into the micro-controller for further processing. This step will be vital for recording the individual items record and cost and process them accordingly (Punitha et al. 2017). Following is the RFID diagram expressing the functioning of the product scan:
            Thus, the input within the micro-controller will be pushed through this process for further processing of the mathematical calculation and cost estimation of the whole products.
Product Scanner
 The product scanner will be processed through the Zigbee module for supporting the mathematical calculation that can be operated at a low-cost web network, is a wireless network and will be consuming low power. The proposed wireless network device will allow the representatives to monitor the budget and products being collected and stored in the buckets and process the billing system accordingly (Maini and Shettar 2014). This information will be transferred to the display screen after analyzing the whole product specification on the single platform. It will thus, increase the rapid rate of the processing of mathematical calculation and will transfer the data and information wirelessly.

            This phase will be helpful in the mathematical calculation and data and information exchange between the Zigbee and the product scanner for displaying the necessary information over the screen.

Smart display

            The collected information related to the products and their cost is being displayed over the screen for the demonstration of the cost and budget of the entire products kept in the cart. This information can be processed for the further processing of the billing of the products. The micro-controller will be playing the crucial role in this phase of the project that will be processing all the collected data and information related to the product details, budget, a number of products and total cost of the bucket and thus, the individual will be informed with the exact amount of the entire products (Awati and Awati 2012). This whole processing will be performed instantly whenever the user put a product in the bucket and thus, the time saving will be a major beneficial factor through this project. It will save time and thus, the cost for the supermarkets and the mall's owner. The developed project will be beneficial for both the consumers and the organization using this product as an integral part for the purchase processing.

Innovation: (establishment of the wireless connection and the smart display tablet screen)

            The IoT, sensors, smart cameras, and fast data processing have been changing the face of the world and hence, these technologies can be used within the supermarket for the further enhancement and introduction of the further innovation for this project. This emphasizes on the establishment of a wireless network and camera network throughout the supermarket and the malls. A smart tablet or mobile device can be embedded within the smart trolley that would allow the user to look for the product and move on to the particular corner where he or she could find the same product without any chaos. This will further eliminate the need for the representatives for directing the consumers as they could find their own way to further processing (Sheba and Rajakumari 2015). This will contribute in the further advancement in the idea being proposed for further processing of the billing system within the supermarkets and the malls. This system will also navigate the users within the mall through the embedded or in-built store map for directing them towards the object they are willing to look for within the supermarket. Following is an example of the user interface for the mobile device directing the consumers within the stores.

System test, evaluation & validation, and optimization process

            Following are the factors those would be considered while performing the system test:
Scalability: the proposed project will be capable of allowing the users to collect the product within the level of the bucket despite of the weight and density. Thus, the users would be able to avail the same services in product selection as they were having in the traditional process. The payment processing would be done as per the price of the product and could vary between 50 cents to as much as the user is interested in spending.
Flexibility: the users would be allowed to move the smart trolley within the supermarket to the parking garage however, they will need to pass through the RFID scanner door where the products will be scanned for billed or not billed product (DawkharDhomase and Mahabaleshwarkar 2015). The users will not have to provide any identification or does not have to register for availing the services and thus, users can avail the services whenever they want to within the supermarket or malls. It could be easily and efficiently handled by any user and no additional knowledge is required for further processing.
Security: security will be the major concern for the supermarket owners as the most crucial process of profit is being transformed completely. The proposed project will be secured enough that can allow the supermarket owners to completely rely on the system as the calculations and the budget estimations could be performed in a much easy and efficient manner (Rupanagudi et al. 2015). RFID tagging will be helpful in tracking the products and thus, users could not leave the venue without paying for the product.
Integration: the system does not need any specifications other than power supply factor and thus, integration of the proposed system will be smooth and effective for the management of the products being purchased from the malls and the supermarkets. The additional computers need to be installed that will be much more cost efficient than assigning the individuals for the billing process.
Acceptance: this will be a major factor for the successful deployment of the project within the real world as the product needs to be accepted by the users. This test can only be performed after proposing the product in front of the consumers and gathering the feedback related to the application of the product.

Evaluation

            The proposed system design assignment could be far beneficial for the consumers for paying the bills purchased from the supermarket or malls.The factors those have been utilized in analyzing the performance of the proposed project turned into to be a beneficial factor. The proposed project will be helpful in managing the operational activities related to the purchase and payment of the products in a much efficient and effective way. Quantitative research can be driven considering the investments and the profit that could be made for analyzing the efficiency of the proposed system (Punitha et al. 2017). The budget of the proposed project is 200$ per trolley and a medium sized mall or supermarkets can operate through average 300 trolleys. Total investment for the project would be
            = 300 x 200$ = 60,000$ (this will be a single time investment)
The normal supermarket and mall have 10 billing counters and so 10 representatives need to be appointed on 10 $ per hour:
Supermarket or malls open for 12 hours and so
Salary to be paid for one day = 120$
Salary for a month = 120$ x 30 = 3600$
For one supermarket, total salary paid for 10 billing counters = 3600$
For a year, total salary paid to the individuals = 3600$ x 365 = 13,14,000$ (assumptions being made that the supermarket will be open every day and the staffs will be working every day)
The above quantitative research explains how effective and efficient could be the proposed project in terms of cost saving for the supermarkets. Thus, the proposed project will not only cost-effective rather it will also be saving time for the consumers in a manner to indulge in some other activities other than standing in a queue for paying the bills.

Conclusion

 It can be concluded in this system design assignment that the proposition of the smart trolley can be helpful in providing the consumer's nest, enhanced and fast services without any tolerance. The proposed system design assignment will be allowing individuals to stay out of the queue and make the payment by just carrying their products in the bucket. The future emphasis can be driven by incorporating the payment system and the navigation of the trolley in the mall by just searching for the product. Automation will further be more applicable in enhancing the reliability factor and allowing the consumers to avail the best services. The above system design assignment also presents a quantitative research based on the cost factor being invested in the staffs as compared to the investment made for the smart trolleys. The proposed system has been identified to be cost-effective, efficient and reliable for the consumers and the supermarkets or malls. System design assignment are being prepared by our enigneering assignment help experts from top universities which let us to provide you a reliable total assignment help service.
