Concurrent engineering (CE) is a work methodology emphasizing the parallelisation of tasks (i.e. performing tasks concurrently), which is sometimes called simultaneous engineering or integrated product development (IPD) using an integrated product team approach. It refers to an approach used in product development in which functions of design engineering, manufacturing engineering, and other functions are integrated to reduce the time required to bring a new product to market.[1]

Introduction[edit]

A 2008 publication described concurrent engineering as a new design management system that has matured in recent years to become a well-defined systems approach to optimizing design and engineering cycles.[2] Concurrent engineering has been implemented in a number of companies, organizations, and universities, most notably in the aerospace industry. Beginning in the early 1990s, CE was also adapted for use in the information and content automation field, providing a basis for organization and management of projects outside the physical product development sector for which it was originally designed. Organizations such as the European Space Agency's Concurrent Design Facility make use of concurrent design to perform feasibility studies for future missions.

It decreases product development time and also the time to market, leading to improved productivity and reduced costs. Concurrent Engineering is a long term business strategy, with long term benefits to business. Concurrent Engineering is a branch of engineering that defines a process in which diverse stages run parallel during the design and development phase. It is counted in a long-term strategy that minimizes the development time but improves quality and productivity. A comparison of the concurrent engineering model and the traditional model of product realization is shown in Figure 5. As it can be seen, there are huge time savings when concurrent engineering is implemented in the design-to-manufacturing cycle of the product realization.

The basic premise for concurrent engineering revolves around two concepts. The first is the idea that all elements of a product's life-cycle—from functionality, production, assembly, testing, maintenance, environmental impact, and finally disposal and recycling—should be taken into careful consideration in the early design phases.[3]

The second concept is that design activities should all be occurring at the same time, i.e., concurrently. The idea is that the concurrent nature of these activities significantly increases productivity and product quality.[4] This way, errors and redesigns can be discovered early in the design process when the project is still flexible. By locating and fixing these issues early, the design team can avoid what often become costly errors as the project moves to more complicated computational models and eventually into the actual manufacturing of hardware.[5]

As mentioned above, part of the design process is to ensure that the product's entire life cycle is taken into consideration. This includes establishing user requirements, propagating early conceptual designs, running computational models, creating physical prototypes, and eventually manufacturing the product. Included in this process is taking into full account funding, workforce capability, and time requirements. A 2006 study claimed that a correct implementation of the concurrent design process can save a significant amount of money, and that organizations have been moving to concurrent design for this reason.[4] It is also highly compatible with systems thinking and green engineering.

Concurrent engineering replaces the more traditional sequential design flow, or 'Waterfall Model'.[6][7] In Concurrent Engineering an iterative or integrated development method is used instead.[8] The Waterfall method moves in a linear fashion, starting with user requirements and sequentially moving forward to design and implementation, until you have a finished product. In this design system, a design team would not quickly look backward or forward from the step it is on to fix or anticipate problems. In the case that something does go wrong, the design usually must be scrapped or heavily altered. The concurrent or iterative design process encourages prompt changes of tack, so that all aspects of the life cycle of the product are taken into account, allowing for a more evolutionary approach to design.[9] The difference between the two design processes can be seen graphically in Figure 1.

A significant part of the concurrent design method is that the individual engineer is given much more say in the overall design process due to the collaborative nature of concurrent engineering. Giving the designer ownership is claimed to improve the productivity of the employee and quality of the product, based on the assumption that people who are given a sense of gratification and ownership over their work tend to work harder and design a more robust product, as opposed to an employee that is assigned a task with little say in the general process.[5]Minecraft download for pc windows 10.

Challenges associated with concurrent design[edit]

Concurrent design comes with a series of challenges, such as implementation of early design reviews, dependency on efficient communication between engineers and teams, software compatibility, and opening up the design process.[10] This design process usually requires that computer models (computer aided design, finite element analysis) are exchanged efficiently, something that can be difficult in practice. If such issues are not addressed properly, concurrent design may not work effectively.[11] It is important to note that although the nature of some project activities project imposes a degree of linearity—completion of software code, prototype development and testing, for example—organizing and managing project teams to facilitate concurrent design can still yield significant benefits that come from the improved sharing of information.

Service providers exist that specialize in this field, not only training people how to perform concurrent design effectively, but also providing the tools to enhance the communication between the team members.

Elements[edit]

Cross-functional teams[edit]

Cross-functional teams include people from different area of the workplace that are all involved in a particular process, including manufacturing, hardware and software design, marketing, and so forth.

Concurrent product realization[edit]

Doing several things at once, such as designing various subsystems simultaneously, is critical to reducing design time and is at the heart of concurrent engineering.

Incremental information sharing[edit]

Incremental information sharing helps minimize the chance that concurrent product realization will lead to surprises. 'Incremental' meaning that as soon as new information becomes available, it is shared and integrated into the design. Cross-functional teams are important to the effective sharing of information in a timely fashion.

Integrated project management[edit]

Integrated project management ensures that someone is responsible for the entire project, and that responsibility is not abdicated once one aspect of the work is done.

Engineering

Definition[edit]

Several definitions of concurrent engineering are in use.

The first one is used by the Concurrent Design Facility (ESA):

Concurrent Engineering (CE) is a systematic approach to integrated product development that emphasizes the response to customer expectations. It embodies team values of co-operation, trust and sharing in such a manner that decision making is by consensus, involving all perspectives in parallel, from the beginning of the product life cycle.

The second one is by Winner, et al., 1988:

Badhai Ho has opened to rave reviews from critics and audience alike. Some of the pirated copies seems to have been shot from a handy camera with average print quality while some have made HD quality prints available. The movie has collected Rs 7.29 crore on the opening day because of the immense buzz and strong word of mouth. Download free movies new releases.

Concurrent Engineering is a systematic approach to the integrated, concurrent design of products and their related processes, including, manufacturing and support. This approach is intended to cause the developers from the very outset to consider all elements of the product life cycle, from conception to disposal, including quality, cost, schedule, and user requirements.[12]

Using C.E.[edit]

Currently, several companies, agencies and universities use CE. Among them can be mentioned:

  • European Space AgencyConcurrent Design Facility
  • NASATeam X - Jet Propulsion Laboratory
  • NASAIntegrated Design Center (IDC), Mission Design Lab (MDL), and Instrument Design Lab (IDL) - Goddard Space Flight Center
  • CNES – French Space Agency
  • ASI – Italian Space Agency
  • Boeing
  • EADS Astrium – Satellite Design Office
  • The Aerospace Corporation Concept Design Center

A college diploma has become a necessity for most working Americans aiming for a comfortable lifestyle. In fact, that college degree is worth $1 million in wages over a lifetime, according to a study by the Georgetown University Center on Education and the Workforce. The question is how to get it without getting crushed under a mountain of student debt.

Here are some ways to find grants, scholarships, and other tuition benefits that pay you, or at least repay you, to earn a degree.

Corporate Tuition Reimbursement

If your employer offers tuition reimbursement as part of a benefits package, taking advantage of this perk can be a straightforward way to get paid to go to school.

Competitive Advantages Of Concurrent Engineering

Tuition reimbursement policies vary. Some employers pay for any degree, while others pay only for education related to their lines of business. Many place annual limits on how much tuition they reimburse or require employees to maintain a certain grade point average to qualify.

If you are looking for a job but hope to go to school in the near future, check out prospective employers' education benefits as part of your job search.

Military Tuition Benefits

Engineering

Higher education benefits and on-the-job training are among the appeals of service in the U.S. military.

These are some of the benefits available as of 2017:

  • Military Tuition Assistance pays up $4,500 per year for eligible recipients. Different rules apply in each branch of the military.
  • Montgomery GI Bill (MGIB) benefits pay about $1,700 per month or up to $64,000 for 36 months of tuition for a broad range of qualifying college and vocational or technical training. You need a minimum of two years of military service in order to qualify for MGIB benefits.
  • Family members of some veterans can get reimbursement for tuition through the Dependents' Educational Assistance program.

College Financial Assistance

Some colleges and universities have student financial aid programs that cover up to 100% of their costs.

Although public universities have lower tuition rates, some private and liberal arts schools with hefty endowments offer more generous financial aid packages.

To qualify for need-based grants and scholarships at such schools, you'll need to fill out the federal government's Free Application for Federal Student Aid (FAFSA). Because colleges determine financial aid based on need, you typically won't need to apply separately for grants or scholarships at the college you choose.

Community College Education

Peliculas completas de risa comicas americanas. If you're considering earning a two-year degree at a community college, you should know that you may be able to get a grant to cover all or part of their tuition simply by submitting a FAFSA application each year.

The most commonly awarded grant is the federal Pell Grant, which awards up to $6,095 to full-time students for the 2018-2019 school year. The maximum covers the cost of full-time enrollment in most community college degree programs. Qualifying students who work and attend community college part-time may be eligible to receive Pell Grant money on a prorated basis.

Merit and Minority Scholarships and Grants

Merit scholarships and grants are awarded to students with a demonstrated track record of achievement in a field. A wide variety is available, with qualifications based on demonstrating excellence in a school sport or achieving a high grade point average.

Other scholarships and grants are awarded to students who are members of minority groups that are underrepresented in college.

The best place to find out about grants and scholarships is through a high school or college counselor or the resources provided by your high school or college.

Advantages Of Concurrent Engineering Approach

You can conduct independent research using websites such as CareerOneStop, sponsored by the U.S. Department of Labor. The site has a wealth of information about professional apprenticeships, certifications, and internships as well as college aid programs. Your state's higher education agency sites also may be useful.
