PurposeThe purpose of this paper is to investigate computer‐aided design (CAD) and computer‐aided engineering (CAE) as enablers of agile manufacturing (AM).Design/methodology/approachBased on the literature review, the importance of technology integration enabling AM has been found. CAD technology has been used for modelling baseline product; CAE has been used for deriving optimized parameters; new designs have been derived.FindingsThe feasibility of CAD and CAE as enablers of AM has been ensured.Research limitations/implicationsThe study has been conducted only in one automotive sprocket manufacturing organization.Practical implicationsThe practical feasibility of generating new products through technology integration has been ensured.Originality/valueVery little research has been reported on technology‐integrated AM practices. In this study, CAD and CAE have been used for enabling product development.

The design of sliding observers is discussed in the paper. The sliding observer is shown to have a simple structure and to be robust with respect to bounded nonlinearities and uncertainties. The Lyapunov-like stability method is used to investigate the stability of sliding observers without assuming the matching condition and a computer-aided design methodology is suggested. A numerical example based on an inverted pendulum with moving support is used to illustrate the proposed design methodology.

PurposeThe purpose of this paper is to explore the researches reported in literature on agile manufacturing (AM) and determine the avenues by which agility can be imparted in traditional sectors.Design/methodology/approachAfter reviewing the literature on AM, it has been found that these papers address AM along as many as 12 directions. The findings of this review are used to design a model called total agile design system (TADS).FindingsThe major finding of the exploration reported in this paper is that, the need of the hour is to sensitize the traditional sectors for acquiring design capabilities compatible for imbibing agility in totality.Research limitations/implicationsThe TADS model proposed has been reviewed only by 25 industry captains. However, this may not affect the credibility of this model as it is designed by referring to a large number of researches reported in peer reviewed articles appeared in leading international journals.Practical implicationsAfter designing, TADS was exposed to 25 industry captains. Their feedback was gathered using a questionnaire. The results of analysis of their feedback indicates the practical compatibility of TADS.Originality/valueIt appears that no researcher has identified the different directions in which AM researches have progressed. Moreover, no researcher has contributed a model to adopt computer aided design (CAD)/computer aided manufacturing (CAM) and rapid prototyping (RP) technologies in totality to achieve agility in manufacturing organisations. As this paper has overcome the absence of these kinds of researches, it is original and valuable.
