โœฆ Synopsis

In today's competitive environment, it is necessary to deliver products on time and within budget. Unfortunately, design projects have been plagued by severe cost and schedule overruns. This problem persists in spite of the significant advances that have been made in design technology over the last two decades. In most of the cases, the problem of overruns was due to poor estimations. The search for a solution has become even more pressing in the present era of shrinking product cycle times. Driven primarily by this need, this paper proposes parametric estimation models. Unlike existing estimation techniques which are based on process or product physical decomposition, the proposed models are based on product functional decomposition. The models were applied to project data collected from two Canadian companies. The results indicate that the proposed models have good accuracy for estimating design effort.

This paper describes an analogy-based model for estimating design effort. It is based on estimating the productivity of an upcoming project by incorporating the concept of an eigenvector to estimate the influence of various factors on productivity. The model is intuitive and does not require any pri

Modelling of physical processes always involves approximations. This undermodelling, coupled with noisy process data, results in biased frequency response estimates of models. The bias error cannot be eliminated, but can be distributed over frequencies by careful design of the estimator. This paper
