Software engineering is the discipline which paves the road map for the development of software within the given schedule and effort with the desired quality. The process begins with estimating the size, effort and time required for the development of the software and ends with the product. In most existing research on the effort estimation, the Function Point Analysis (FPA) method is used to e...

The increased use of advanced composites in aerospace manufacturing has led to the development of new production processes and technology The implementation of advanced composites manufacturing technology is poorly served by traditional cost accounting methods, which distort costs by using inappropriate volume-based allocations of overhead. Activity-based costing has emerged as a methodology, w...

ABSTRACT Six Sigma is a widely used moniker to represent a set of design and manufacturing techniques, the aggregate of which should effectively improve quality and lower cost. Six Sigma implies that six standard deviations of performance should be maintained between the performance mean and the closest specification limit. When multiple performance attributes must be satisfied, aggregation tec...

  Selecting an effective project plan is a significant area in the project management. The present paper introduces a technique to identify the project plan efficient frontier for assessing the alternative project plans and selecting the best plan. The efficient frontier includes two criteria: the project cost and the project time. Besides, the paper presents a scheme to incorporate Directed Ac...

The objective of Empirical Software Engineering is to improve the software development and maintenance processes and consequently the quality of theirs various deliverables. This can be achieved by evaluating, controlling and predicting some important attributes of software projects such as development effort, software reliability, and programmers productivity. One of the most interesting sub-f...

Accurate effort prediction is an ongoing challenge to software engineers. It is an important task in the management of software projects. Effort estimation is the challenging and is an important area in the software project management research field. The development of software has always been characterized by the parameters that contain certain level of fuzziness. This requires some degree of ...

OBJECTIVE – The objective of this paper is to investigate the use of a Bayesian Network (BN) for Web effort estimation. METHOD – We built a BN automatically using the HUGIN tool and data on 120 Web projects from the Tukutuku database. In addition the BN model and node probability tables were also validated by a Web project manager from a well-established Web company in Rio de Janeiro (Brazil). ...

Academia and practitioners confirm that software project effort prediction is crucial for an accurate software project management. However, software development effort estimation is uncertain by nature. Literature has developed methods to improve estimation correctness, using artificial intelligence techniques in many cases. Following this path, this paper presents SEffEst, a framework based on...

Poor estimates of effort and schedule are frequently responsible for software project failure. Accordingly, there is a need to investigate and better understand the impact of requirement changes (RC) on software development projects in terms of effort. Requirements changes are unavoidable and unpredictable during the development of most software projects. Regardless of software development team...

Postponement is a growing trend in manufacturing. It can lead to superior supply chains. Form postponement (FP) involves the delay of final manufacturing until a customer order is received and is commonly regarded as an approach to mass customisation. Mass customisation is a trend towards the production and distribution of individually customised goods and services for a mass market. It is prov...
