Concurrent engineering vs traditional sequential methods
Conventional study approach compared to Concurrent Engineering Working within a guided process, the concurrent access of all experts to a shared database, and the direct verbal and medial communication between all subsystem experts, are the defining characteristics of Concurrent Engineering studies.
Following the design stage, the CE team compares the derived cost of the product design to the targeted cost. Decision making involves full team participation and involvement.
Concurrent engineering adalah
This includes establishing user requirements, propagating early conceptual designs, running computational models, creating physical prototypes, and eventually manufacturing the product. 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. Without their implementation and further upgrading, concurrent engineering might never be able to realize its full potential in terms of design cost and lead-time optimization. Reducing or eliminating these extra steps means the product will be completed sooner and with less wasted material in the process. Failure Mode and Effects Analysis FMEA allows for a systematic investigation of the occurrence and impact of possible flaws in the new product design. At the beginning of the s, the automotive industry pioneered many of the concurrent engineering concepts and their implementation. Cross-functional teams are important to the effective sharing of information in a timely fashion. The different steps are done one after another, with all attention and resources focused on that one task. However, this trend has not been limited to individual companies; complete industry sectors also have implemented concurrent engineering principles. Decision making involves full team participation and involvement. The fact that concurrent engineering could result in faster time-to-market is already an important advantage in terms of a competitive edge over other producers. Second, more revolutionary new product development, which often is based on significant technological advances, typically requires longer time horizons to reach completion. Due to large amounts of time allocated towards all stages of product development, sequential engineering is associated with high cost and is less efficient as products can not be made quickly. After the design team completes its task, the production processes are designed based on the design of the product. During design and development projects, methods are utilized that foster and support smooth interdisciplinary problem definition and problem solving.

In fact, the time and cost incurred by the development and construction of prototypes generally are reduced by factors of 2 to 5 when using digital e.
After it is completed it is left alone and everything is concentrated on the next task. Some examples of these technologies include: three-dimensional 3-D computer-aided design CAD systems, rapid prototyping techniques, rapid tooling and rapid testing techniques, as well as techniques that enable the representation of product designs in a virtual context.
The benefits of concurrent design and manufacturing can be sorted in to short term and long term. Although mostly focused on satellite design, exploration missions and space transport systems, the CEF has enabled the study of life support systems, and space-based or terrestrial infrastructures.
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 engineering is a key method for meeting this need of shortening a new product's time-to-market. By engaging in multiple aspects of development concurrently, the amount of time involved in getting a new product to the market is decreased significantly.
These design technologies are important because of the key information they convey: their 3-D character allows the expert to interpret design features in a more effective and efficient way. Reducing or eliminating these extra steps means the product will be completed sooner and with less wasted material in the process.
