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.

Construction design, one of the oldest specialties in civil engineering, is a combination work of architectural design and structural analysis. By the development of computer technology, the idea of construction design has been revolutionary changed. This paper introduces a new construction design methodology considering both evolutionary structural optimization and 3D model printing technology. Instead of manual drawing and planning, computer-aided design (CAD) is the used to assist in the creation, modification, or analysis of an architectural design. Computer-aided design involves more than just drawing. In structural engineering area, by using the finite element analysis software (ABAQUS), evolutionary structural optimization (ESO) method can improve the design in defining shape, choosing material and calculating the tolerance of a construction. Finally, the computer designed digital model is made into a three dimensional solid object from the 3D model printer. The solid model can give a visualized view of the whole construction.

Purpose Various occupations in life require personnel to stand for a prolonged period of time. This causes excessive stress on the joints leading to musculoskeletal disorders. This paper aims to design an equipment ensure the personnel rests on whenever necessary. Design/methodology/approach The method followed in this paper is the adoption of Karl Ulrich’s product design methodology with suitable modifications as per requirement. Human anthropometric data from the Indian population has been considered during the design and modelled according to it using computer aided design and computer aided engineering tools. Findings The conceptual equipment – exoskeleton designed sustained loads of human beings and proved to be a safe design in terms of the strength of the material used in the design. Social implications This design can serve as equipment, which helps the personnel with long-standing work hours to relieve themselves without actually sitting. Originality/value The design has been carefully crafted based on the inputs from the anthropometric features of human beings, which is completely passive in nature i.e. no use of external power is required for this exoskeleton compared to the other available designs.

Theoretical Results

The results of integrity of narrowband and wideband lumped element circulators design methodology to the computer aided design system of microwave devices AWR Microwave Office are presented in the article. The calculation method of narrow band circulators circuits which consist of serious and shunt tuning capacities is investigated. The simple and visual method of wideband ferrite isolators optimize design based on circulation impedance calculation is described here. The results of design of the ultra wideband circulator with shunt capacity, serious resonant matching circuit and serious resonant circuit between common terminal and ground are considered. The new theoretical results of calculation of two schematics of wideband high power circulators with serious tuning capacity are presented. The first schematic is formed with matching resonant network being connected in serious at each terminal. It is shown that double hump characteristic is realized. The second schematic is formed with serious resonant network connected between common terminal and the ground. It is shown that four-order Tchebycheff characteristic is realized.
