Preliminary design
The main objective of this phase in system engineering

1.
The requirements which are defined in the conceptual design phase are reviewed and
updated.

2.
The technologies which are identified while conceptual design phase are investigated and
refined to establish a preliminary design and technical solutions for the system.

3.
The requirements are developed on the basis of solution of conceptual design
architectural system.

The cost budget and subsystem functional are reviewed and updated as per requirements while

starting the preliminary design phase. The detailed technical solution and the optimal system

architecture are selected in this phase. The reliability and safety requirements are verified to

conduct reliability and safety assessments. The evaluation of risk will be updated which includes

options of reviewed mitigation. Control procedure will be implemented to maintain the integrity

of the system. At the last step in preliminary design, evaluation was done according to the

budget, the schedule, the target cost and the organization requirements of the selected design

solution. (Ryen, E. 2008)

Functional analysis
Physical components which are named as building blocks are identified by functional analysis. It

is used to build up the future product. There are different levels in a project such as subsystem

level, system of systems level on which functional analysis can be applied. Shape memory

alloys, elastomeric bearing, base isolation technique, ductility are the components which are

identified in functional analysis. Higher level functions are identified by decomposing via

analysis of requirements into low-level functions in function analysis. Functional analysis allows

better understanding of the system that what ways it can do it and what the system has to do. It

provides the important information which optimizes the physical solutions.

Detailed design

Requirement is the important step while developing any project. Requirements should be well-

defined to plan a program for project manager which should be followed. Engineers should know

what to build check the requirements of the user’s community and how to build and scientists

should be able to validate the system to There are different materials which are used to construct

the shockproof structure of building. Steel and concrete are the materials which are used in

construction but these materials can’t handle bridges which are strong. The researchers find the

alternatives to concreate and steels in bridges.( Sebokwiki,2018)

Shape memory alloys are the elements which provide the facility of withstand strain, super

elasticity and heating. Example of shape memory alloys is Nickel-titanium which has super

elasticity and is temperature sensitive. It can re-center bridge columns which reduced the

permanent tilt columns. Glass carbon fiber-reinforced polymer was tested to prevent damage,

utilize shake tables and strengthen concrete which enhanced.

An elastomeric bearing is a steel plate placed on the thick rubber pad on the concrete to allow the

bridge not to obtain the stress. It should be utilized allow the movement of thermal, contraction,

expansion with ambient bridge temperature .It has ability to carry loads of large vertical loads

due to reinforcement which prevents building of elastomer. There are many types of elastomeric

bearing such as steel reinforced, cotton duck and fiberglass reinforced bearing pads.( The

Constructor. 2018)

Ductility is important to cover the bridge columns in fiber or steel reinforced polymer jackets.

This is a wrapping process which is also named as passive confinement.

The Base isolation technique is used to prevent or to degrade the damage to bridges due to

earthquakes and heavy loads. Base isolation system is an important requirement for providing

flexibility and resistance to vertical service loads. There are many types of isolators such as flat

sliding bearing, elastomeric rubber bearing, sliding bearing high damping bearings, pendulum

bearings ,lead rubber bearing etc. Low cost, the bridges are protected and ensures structure

safety, the performance of the structure is improved are the advantages of this technique.

TPM stands for total productive maintenance which is a holistic approach. It is used to achieve

perfect production by equipment maintenance. It has no breakdowns, no defects and no slow

running or small stops. It provides a safe environment for working. It maximizes the equipment

operational efficiency by emphasizing preventative and proactive maintenance. The distinction

between maintenance and the roles of production gets blurs by locating a strong emphasis which

helps to maintain their equipment. TPM program implementation creates a responsibility shared

for equipment which motivates more involvement by plant floor workers. It improves

productivity effectively.

System test, evaluation, validation and optimization processes

System development and construction of building design includes iterative process in which

development steps and detailed study of design is constituted. The steps of designing building

are requirements in designing of system components are discussed, objectives of designing are

completed with the implementation of technical activities, elements and activities of system are

integrated, utilize the designing tools which are selected, documentation of data are prepared,

prototype models are developed, evaluation, review for design and feedback are implemented

and changes which are required and appropriate are incorporated in the design. The life cycle to

shockproof building is examined with specified primary functions.(AcqNotes. ,2018)

The requirement of construction shockproof building is the material concrete, masonry and steel

which reduce the damage risk of earthquake resistant. The main objective to build the

shockproof building is reduces the risk of earthquake forces and provide protection to the

buildings. Feasibility evaluate whether the shockproof approach would be technically and

financially feasible or not to build the bridge. There are three types of feasibility as giver below:

1.
Technical feasibility: The equipments which are used to construct the shockproof
building are checked i whether software or equipments will satisfy or fulfil the user

requirements or not. The output is produces in a given time ,response time under

specified conditions, at a specified speed it provide ability to process transaction of a

certain volume, It provide facility to communicate data to distant location are included in

technical feasibility.

2.
Economic Feasibility: The effectiveness of a proposed system is evaluated in economic
analysis. It determines the costs of the proposed system .If the cost overweigh then a

decision is taken by engineers to design and implement the system.
Document Page
3. Operational feasibility: The operations which are performed by the engineers to develop
the system in included in this feasibility. The drawbacks of building or bridge are

analyzed. This feasibility considered the steps such as what changes are required for the

system, organizational structure of the bridge which is disturbed ,What kinds of skills are

required and do the staff members of the existed system have these skills?

This feasibility includes the limitations of building or bridge and then requirements which

are needed to overcame the limitations. The skills which are required to construct the

bridge which reduces the risk .

The technical knowledge of the domain in which engineer operates system and systems

engineering management are the two disciplines which are significant in the system engineering.

The objective of the system engineering is to provide flexibility in the process to which converts

requirements into specifications. In the development process, the process of system engineering

can be repeated more than one time .In the life cycle, development process and the planning

associated with planning are included. It reduced the requirement for rework substantially,

product cycle -times and redesign.

The system engineer customers perform the functions of life-cycle. The requirements of the

system users are emphasized due to the needs of the customers generate the systems engineer

requirements. The technical tasks such as planning, tracking and coordinating are performed

during development in systems engineering. The system engineer’s responsibilities are

The solution of whole system design development balances cost, risk, performance and risk. The

technical information tracking and development are required to decision making. Technical

solutions verification is required to fulfil the requirements of customer. The system development

which produced economically is supported entire life cycle. The interface of the systems and

subsystems are monitored internally and externally by open systems approach. Configuration

control and baselines are established.

Validation

The solutions which are provided are compared to the customers’ requirements and this phase is

known as validation phase. Development at each level for each requirement must be verified.
