“…Saravi et al (2008) cite Ullman (2003) and then Corbett (1986) and Mileham et al (1993). Saravi et al interpretation of Corbett is wrong and their addition of Mileham et al as a reference is redundant because the latter refer only to Corbett (and they do it correctly) as their support of the IISP.…”

“…The design decisions made in the early design stages (i.e. conceptual and preliminary design phases) have a significant impact on the constructibility of a product, as between 70 and 80% of the construction cost is determined by design [26,27]. Thus, cost reduction efforts must be …”

Design-build as a procurement method is increasingly being used in the design and construction of greenfield rail networks, and that is despite the complexities that characterise rail networks-rail infrastructure projects involves significantly more complex systems such as safety, telecommunications, signalling and electrification. One of the key drivers for this choice of procurement method for the delivery of rail networks is that the design-build contractor commits to an aggressive schedule and implements strategies to enable the works to be completed to time and cost. One of such strategies is the application of concurrent engineering principles to the design and construction works. This Chapter gives an overview of concurrent engineering as applicable to design-build rail projects, focusing mainly on the design as an activity. It identifies factors that impact the application of concurrent engineering as well as mitigations that can be applied for the successful application of concurrent engineering principles in design-build rail projects.

“…Cost estimation can be carried out in each stage of a product life cycle, such as conceptualization, concept design, detailed design, prototyping and manufacture. Many researches recognize that up to 80% of the product cost is determined at the conceptual and design phases [3]. Therefore, accurate cost estimation at early stages and with different levels of defined details has an important role in manufacture success.…”

Abstract-To address the requirement of dynamic pricing and cost control in high-variation product manufacturing, nowadays many companies face the problem of generating quotes and order prices timely, accurately and consistently. A generic semantic model for the purpose of automatic cost estimation is proposed, in which a new concept named cost feature, is suggested. A cost feature can be identified with data mining methods for different targeted clients or products, and conceptually interfaced with product design and manufacturing features. Feature-based mapping model is used to determine feature scope and cost level defined, including all the dependency relations with other domain features. This model is expected to enable a visual, flexible and semantically consistent scheme to address effective and efficient product cost structures, frequent configuration variations and business changes. A case study is used to illustrate this new method. The preliminary study shows that the proposed method is potentially effective for manufacturers.Index Terms-Cost estimation, semantic modeling, product pricing, associative feature, cost feature. I. INTRODUCTIONIn today's competitive world and the on-line business era, effective and timely cost estimation has a critical role in manufactory's success. In terms of practical applications, industry needs to quickly estimate the price for any new product configuration in a customer order either interactively or automatically by on-line applications. High cost estimation accuracy at the very early stage and effective cost control during the operation phase are essential for the smooth business operation. Quick and accurate cost estimation brings lots of advantages over competitors. Cost estimation can also affect all aspects of production processes and management decisions, such as choosing between producing the product components in-house or outsourcing the product.There have been a number of researchers who studied on accurate cost estimation for manufacturing products which in turn is a part of cost engineering. Cost engineering also defines the process and conditions for forecasting a product's price [1]. There are also lots of methods and tools for doing Manuscript received April 10, 2013; revised July 10, 2013 cost estimation. In general, cost estimation methods have two main categories: traditional and advanced approaches. Traditional cost estimation approach includes bottom-up engineering, analogy, and parametric methods. This approach is fundamentally based on historical data and experience knowledge.Advanced cost estimation approach includes expert judgment, feature-base evaluation, fuzzy logic, neural networks and data mining (DM) methods. This approach is more suitable for complex product and dynamic cost estimation [2]. Cost estimation can be carried out in each stage of a product life cycle, such as conceptualization, concept design, detailed design, prototyping and manufacture. Many researches recognize that up to 80% of the product cost is determined at the concept...
