Abstract

States that reduction in this period of time between design and delivery of the product to the customer can lead to improved profitability, higher levels of customer satisfaction and increased market share. Points out that most cycle time reduction programmes are closely tied to an organization’s quality improvement programme and therefore not an isolated activity. Discusses new approaches to cycle time reductions including cycle time reduction through emphasis on loops and through re‐engineering. Provides short case studies as examples in practice.

Abstract

Purpose

This paper presents an investigation on the line balancing of an automated cylinder block production transfer line in order to reduce the total cycle time and increase machine utilization in an automotive plant. Results were verified by computer simulation, which showed increased throughput and higher machine utilization as a result of line balancing.

Design/methodology/approach

Three main operation lines of the transfer line were identified as critical and having the highest cycle time and were chosen for optimisation study. Strategies of re‐sequencing of existing operations and tools were used to reduce the cycle time of these critical operations and to balance the line. Results of a simulation study using Simul8 software are also presented to demonstrate the increase in machine utilisation and throughput as a result of line balancing.

Findings

Owing to line balancing, the cycle time of cylinder block line was reduced from 293.9 to 200 s, an almost 32 per cent reduction. This also resulted in increased throughput and machine utilisation. Throughput was increased by 65 per cent. Machine utilization was found to increase at all stations, with the highest increase at one station was recorded from 48 to 95 per cent due to balancing.

Originality/value

Introduces a new application to line balancing of automotive cylinder block production line. Demonstrates that effective strategies of re‐sequencing and changing of tools can lead to more balanced production line with increased throughput and higher machining utilisation, resulting in higher productivity.

Abstract

Examines how marketing research affects cycle time (the time from product conceptualization to product introduction), in technology‐driven industries. The key research question to be examined in this study is: how do the collection, dissemination and utilization of marketing research information affect cycle time? Focuses on the telecommunications industry as an industry in which technology often drives the dynamics in the marketplace. Presents an empirical examination of the key research question in an exploratory study of hardware firms in the telecommunications industry. The results suggest that the collection of marketing research does not impact cycle time significantly. However, increased frequency of dissemination of the information collected via marketing research can increase cycle time. Finds also that, while the utilization ofmarketing research in designing products can increase cycle time, utilization of marketing research for strategy development can actually reduce cycle time. Thus, incorporation of marketing research in new product development can aid the introduction of new products in a timely manner.

Abstract

Reviews the literature of purchasing and transportation management to identify factors in the purchasing and transportation processes that influence a firm’s ability to reduce total cycle time. Presents a model of these factors to establish a framework for guiding research into comprehensive, systematic approaches to total cycle time reduction. In addition, the total cycle time model serves as a blueprint for practitioners in evaluating, in specific organizations, the effect of the purchasing and transportation processes on total cycle time. Although much of the research reviewed herein dates to the early 1980s its consideration as part of a comprehensive, systematic examination of the total cycle time concept is new.

Abstract

The definition of cycle time is the time from the wafer start to the wafer output. It usually takes one or two months to get the product since customer decides to produce it. The cycle time is a critical factor for customer satisfaction because it represents the response time to the market. Long cycle time reflects the ineffective investment for the capital. The cycle time is very important for foundry because long cycle time will cause customer unsatisfied and the order loss. Consequently, all of the foundries put lots of human source in the cycle time improvement. Usually, we make decisions based on the experience in the cycle time management. We have no mechanism or theory for cycle time management. We do work‐in‐process (WIP) management based on turn rate and standard WIP (STD WIP) set by experiences. But the experience didn’t mean the optimal solution, when the situation changed, the cycle time or the standard WIP will also be changed. The experience will not always be applicable. If we only have the experience and no mechanism, management will not be work out. After interview several foundry fab managers, all of the fab can’t reflect the situation. That is, all of them will have an impact period after product mix or utilization varied. In this study, we want to develop a formula for standard WIP and use statistical process control (SPC) concept to set WIP upper/lower limit level. When WIP exceed the limit level, it will trigger action plans to compensate WIP Profile. If WIP Profile balances, we don’t need too much WIP. So WIP level could be reduced and cycle time also could be reduced.

Abstract

Purpose

This study seeks to evaluate the importance of new product development cycle time for firms that have a strategy of pursuing exporting as a means of achieving and sustaining competitive advantage.

Design/methodology/approach

A mail survey utilizing the key informant approach for selecting senior executives of US manufacturing firms was chosen because of the importance of executive involvement in international marketing strategy decisions.

Findings

This study supports the argument that faster new product development capability must be augmented for firms striving for a higher degree of export involvement. Additionally, the importance of integrating the marketing, R&D, and engineering functions to develop competitive advantage is highlighted.

Research limitations/implications

Results must be interpreted as explorative since the sample was based on US manufacturing firms. Additional research is needed to test differential effects of innovative product and modification/extension cycle time on export involvement and other indicators of performance.

Practical implications

This study demonstrates the importance of the resource‐based theory of competitive advantage, new product development cycle time as a determinant of export involvement, and competitive advantage for firms which pursue international opportunities. It suggests that product development capabilities are not a critical determining factor of the level of export involvement. The findings show that the ability to develop competitive products faster than competitors is a prerequisite for export involvement.

Originality/value

This study suggests that the speed of new product development is a precondition for export involvement and that the new product development cycle time measures were significantly related to the perception of a firm's overall competitive position in global markets.

Abstract

Purpose

A problematic issue for new approaches to prefabricated timber construction is simply that there is insufficient productivity measurement data to assist estimation of resource usage, speed onsite and best practice. A lack of information potentially results in increased pricing behaviour which may slow the uptake of prefabricated construction. The purpose of this paper is to measure installation productivity onsite for prefabricated timber floor cassette panels and develop sufficient understanding of the process to suggest improved practices.

Design/methodology/approach

A time and motion approach, paired with time-lapse photography was used for detailed capture of prefabricated cassette flooring installation processes onsite. An emphasis was placed on work flow around crane cycles from three case study projects. Time and date stamping from 300 crane cycles was used to generate quantitative data and enable statistical analysis.

Findings

The authors show that crane cycle speed is correlated to productivity including gross and net crane time scenarios. The latter is refined further to differentiate uncontrolled outlying crane cycles from normally distributed data, representing a controlled work process. The results show that the installation productivity rates are between 69.38 and 123.49 m2/crane-hour, based on normally distributed crane cycle times. These rates were 10.8–26.1 per cent higher than the data set inclusive of outlier cycles. Large cassettes also proved to be more productive to place than small.

Originality/value

The contribution of this research is the focus on cranage as the lead resource and the key unit of measure driving installation productivity (in cassette flooring prefabricated construction), as distinct from past research that focuses on labour and craft-based studies. It provides a different perspective around mechanisation, for resourcing and planning of work flow. Crane cycles provide a relatively easy yet reliably repeatable means for predicting productivity. The time-lapse photographic analysis offers a high degree of detail, accuracy and objectivity not apparent in other productivity studies which serves to enable quantitative benchmarking with other projects.

Abstract

Purpose

The purpose of this paper is to examine the long-term reliability of an anisotropic conductive adhesive (ACA) attached polyethylene terephthalate (PET) flex-on-board (FOB) assembly for industrial application used in harsh environments. In addition, the possibility of reducing reliability testing time was studied.

Design/methodology/approach

A−40/+125°C thermal cycling test with 5- and 14-minute soak times was used to study the reliability. To study the functionality of the FOB assembly during testing, a real-time resistance measurement was used together with a 90° peel strength test. Failure analysis was performed on samples using scanning electron microscopy and cross sectioning.

Findings

No failures or noticeable increase in the measured resistance values were seen during testing. The peel strength, however, decreased significantly with both soak times used. The highest drop in the mechanical strength occurred at the start of the temperature cycling tests. The time spent at the high temperature extreme seemed to have a greater impact on the peel strength than the number of temperature cycles. The failure mode of peel tested samples changed due to temperature cycling from interfacial delamination to cohesive failure. The temperature cycling was also observed to induce voiding inside the adhesive.

Originality/value

The paper illustrates the applicability of ACA attached PET flex in high reliability industrial applications. Additionally, testing methods for high reliability adhesive interconnections are discussed. Especially, the effect of temperature cycling soak time on peel test results and reliability testing time is studied.
