Multi-objectives exception management model for semiconductor back-end environment under turnkey service

On-time delivery is the need for customer satisfaction which is a critical factor in the survival of the semiconductor industry. The on-time-delivery performance of the whole semiconductor turnkey service depends on the performance of the back-end factories. Unfortunately, undesirable and inevitable production variations make it difficult to maintain and improve a factory's performance and more objectives such as cycle time, throughput rate and the due-date accuracy need to be simultaneously considered. This paper presents an exception management model in order to compromise the contradicting needs of delivery accuracy, throughput rate and cycle time. The exception model can be divided into three parts: (1) an integrated performance index is proposed to compromise multiple performance measures; (2) an AWDL (available WIP deviation level) determination model is designed to gather proper AWDLs for triggering exceptions and (3) a WIP correction action is proposed to make abnormal WIP levels back to normal levels as soon as possible. To evaluate the proposed WIP exception management model, a simulation model is constructed and experiments are then conducted. The simulation results show that the proposed model helps back-end factories to set proper exception triggering conditions, reduce uncertainty occurrences and achieve better performances on due dates.     

Universal equation for the relative change in profit of manufacturing company

In contemporary conditions of the company's business operations, where high dynamics of costs, sales volume and change of production programme is present, it is of crucial importance to investigate their effects on the change of profit. Starting from cost–volume–profit equation, the aim is to arrive at a universal equation that will simultaneously measure a relative change in profit for a number of products, not only under the influence of change in sales volume but also of other relevant variables, such as sales price, fixed and variable costs. The basic hypothesis is that it is possible to establish in a form of universal equation the dependence between the change in profit and change in influential variables. In this investigation, first it was observed the partial influence of some variables on the change in profit and their dependence was determined for a single product, and then for more than one product. Finally, by summing up all those effects, a universal equation of profit change was obtained. The derived universal equation for the relative change in profit along with simultaneous effects of several variables makes possible for the company management to more simply determine the profit for diverse conditions of business operations. The universal equation for the relative change in profit was applied in one company and the results obtained confirm its significance.     

Inter-firm collaborations and supply chain coordination: review of key elements and case study

Considering the effects of globalisation, the increase of production and energy costs, and the introduction of advanced technologies, companies need to change their way of doing business if they want to stay competitive. One way of doing this is to establish collaborations with suppliers, distributors and retailers, in order to exchange products efficiently and create value for customers. Nevertheless, the structure of the collaboration must be designed carefully and some coordination mechanisms must be implemented to support this way of doing business. In this article, we first analyse: why companies work together, how they should build their partnership, and which strategies they can implement to facilitate coordination of supply chain activities. We then report a case study of collaboration in the forest industry that shows the benefits of implementing coordination mechanisms as well as the necessity of using incentives to better share these benefits.     

Application of load-oriented manufacturing control in industry

This paper deals with multi-stage lotsizing models for imperfect production processes. The effect of imperfect quality on lotsizing decisions and effect ofinspection errorsare taken into consideration in the proposed models. Numerical examples are presented for illustration purposes. The developed models are very helpful for justifying quality assurance and quality improvement efforts.     

Knowledge transfer of the Western concept of quality

This paper addresses one of the issues in contemporary globalization theory: the extent to which there is 'one best way' in which business can be conducted and organizations managed. It uses Czarniawska's 'travels of ideas' model as an organizing framework to present and understand how the concept of 'quality', so important in contemporary approaches to manufacturing and services, and their management, travelled to, and impinged on, a newly opened vehicle assembly plant in Poland. The extent to which new meanings were mutually created in the process of translation is discussed, using ethnographic reporting and analysis techniques commonly used in diffusion research. Parallels between the process of translation as an idea becomes embedded into a new cultural location and the processes which contemporary research has identified as important to organizational learning are briefly discussed in conclusion.     

Gender,power and office politics

Abstract

This interpretative study explores the experiences of Taiwanese female clerical workers as they deal with office politics. A hermeneutical phenomenology is used to describe and interpret the participants' experiences. The study shows that powerlessness and frustration result from: (1) structural barriers; (2) behavioral barriers; and (3) accommodation and rationalization. This study has implications for research and practice in international area of women's studies and for the field of international career development education.     

How business associations use interorganizational networks to achieve workforce development goals: Implications for Human Resource Development

Abstract

This study uses data from a series of comparative case studies to analyse the interorganizational networks of business associations providing workforce development services in the United States. Three aspects of the networks were of particular interest, including (a) the form the partnerships took, (b) the trade-off to involving educational or community vs. business partners in providing workforce development services and (c) the strengths of associations in brokering services to adults or youth. The findings demonstrate that business associations work in intermediary networks or provide their services directly. The conclusions suggest that human resource development professionals should work more actively with local business associations to recruit, train and provide supports for workers in US firms.     

Key personality traits of engineers for innovation and technology development

Focusing on new roles of engineers for technological innovation and internal entrepreneurship, we examined the personality traits of 4876 engineers versus 75,892 non-engineers. Engineers scored higher on Tough-Mindedness and Intrinsic Motivation; but lower on Assertiveness, Conscientiousness, Customer Service Orientation, Emotional Stability, Extraversion, Image Management, Optimism, Visionary Style, and Work Drive. All but four of these traits were positively related to engineers’ career satisfaction. Overall, the results are not encouraging for the new roles of engineers such as intrapreneurship. Findings were discussed in terms of occupational profiling of engineers as well as career planning, selection, training, and professional development of engineers.     

Build-operate-transfer Outsourcing Contracts in Services – Boon or Bane to Emerging Market Vendor Firms?

Build-operate-transfer (BOT) contracting has been widely used in the engineering and construction industry and has recently spread into the service industry domains. Notably, service provider firms from emerging markets, India in particular, are now offering BOT outsourcing contracts in which the client firms are allotted call options, i.e. the right, but not the obligation, to transfer pre-specified assets from the service provider. As such, BOT outsourcing contracts seems to be an interesting contractual novelty that combines the advantages of outsourced and captive offshoring operations. In this paper we investigate under which circumstances a BOT outsourcing contract (i.e. a contract where the client firm exercises its call option) is beneficial, or the opposite, to the emerging market vendor firm. Whether BOT outsourcing contracts are boon or bane to an emerging market vendor basically hinges, we submit, on its internal diffusion of client-specific knowledge and capabilities prior to the execution of the call option.
