A lot sizing and sequencing algorithm for dynamic demands upon a single facility

A heuristic algorithm is developed and applied to determine lot sizes and production sequence on a single facility. The various product demands are treated as deterministic and time varying (dynamic) over a finite planning horizon, such as that generated from a material requirements planning (MRP) system.In contrast to other approaches available, the algorithm considers the sequencing decision in each period by realistically assuming inventory holding cost occurrence in the period of production, and in addition, it is capable of considering set-up times where such set-up times consume available productive capacity. The ability to handle numerous products, and the capability of being able to specify maintenance time and holidays is an integral aspect of the algorithm.The results of an application of the algorithm in a medium size bearing company have shown very significant reduction in the controllable inventory holding cost while eliminating late deliveries. In an effort to cope with potential realistic schedule alterations, different solutions were developed for managerial evaluation providing greater flexibility but at a higher cost.     

Restructuring in the West Midlands'clothing industry

This article reviews the flexible specialisation debate in the context of the clothing industry in the West Midlands. It questions the central importance given to the introduction of technology in the recent restructuring of the industry and argues that such changes do not necessarily benefit the workforce.     

Towards a new perspective on accounting control

What new insights, if any, can be gained by a systems approach to business planning and control? By far the most important one is that the types of organizational and control objectives and performance measures appropriate to complex open systems will differ from those now in use. It is proposed that the organizational objective should be to maximize adaptability subject to a minimum degree of stability. Corresponding aggregate and costing period performance measures are tentatively discussed.     

Training and development deficiencies in ‘high skill’ sectors

Policy debates across advanced industrial economies are stressing the centrality of skills and training to compete in the new ‘knowledge economy’. In the UK increasing importance is being placed on improving workplace learning, yet policy has so far failed to confront the issue of employers' lack of investment in training and development. This article examines whether the high skill sectors that exist within the UK can provide a model of workplace learning for other such sectors to emulate. By using case study research from the aerospace and pharmaceutical industries, training and development practices are examined in relation to the requirements of the business and individual employees. The article will argue that the companies in question, despite their favourable product market position, remain constrained by the broader institutional environment.     

The emergence of small transnational enterprise in Vancouver: the case of Chinese entrepreneur immigrants

This article examines the small transnational enterprises of recent Chinese entrepreneur immigrants to Vancouver, Canada. These enterprises are part of the globalization process and contribute to the economic and cultural integration of certain regions of Asia with large urban areas of Canada. The entrepreneurs are analyzed utilizing a transnationalism framework which is situated in the ethnic enterprise literature. The article explains how these transnational small Chinese businesses are different from the businesses of earlier Chinese in Canada. A detailed analysis of the Canadian Business Immigration Program illustrates how and why small Chinese transnational enterprises have emerged. The primary data comes from extensive in–depth interviews with 61 Chinese entrepreneur immigrants that allows for the delineation of three transnational business types: (1) Asian production–North American distribution, (2) retail chains and (3) import–export. Quantitative data illustrate the major differences between ‘transnational’ and ‘non–transnational’ enterprises along several variables. Other qualitative data provide insights on how family networks are interwoven with firm relations in small transnational businesses, how entrepreneurs perceive interethnic relations and the extent to which they experience barriers to mobility. Evidence is provided of extensive transmigration and, in contrast to the sojourner identity of earlier Chinese, the data here suggests the emergence of a new transnational and cosmopolitan identity amongst entrepreneur immigrants. Cet article étudie les petites entreprises transnationales des récents immigrants chinois de Vancouver (Canada). Celles–ci s’inscrivent dans le processus de mondialisation et contribuent à l’intégration économique et culturelle de certaines régions d’Asie dans d’importantes zones urbaines canadiennes. L’analyse de ces créateurs d’entreprise est faite à partir d’un cadre d’analyse transnationaliste qui se situe dans la littérature sur l’entreprise ethnique. L’article explique en quoi ces petites entreprises chinoises transnationales diffèrent de celles des Chinois arrivés plus tôt au Canada. Une étude détaillée du Programme canadien d’Immigration des Hommes d’affaires explique comment et pourquoi sont apparues ces petites entités transnationales. Les principales données, tirées d’entretiens approfondis avec 61 entrepreneurs chinois, permettent de définir trois types d’entreprises transnationales: production asiatique avec distribution nord–américaine, chaînes de détaillants, et import–export. Des données quantitatives illustrent les grandes différences entre les entreprises ‘transnationales’ et ‘non–transnationales’ en fonction de plusieurs variables. D’autres données quantitatives révèlent de quelle manière les réseaux familiaux s’entremêlent avec les relations professionnelles dans les petites entités transnationales, comment les chefs d’entreprise perçoivent les relations inter–ethniques et dans quelle mesure ils rencontrent des obstacles à leur mobilité. Une importante transmigration est mise en evidence et, par opposition au caractère temporaire du séjour des premiers Chinois, les données suggèrent ici l’émergence d’une nouvelle identité transnationale et cosmopolite chez les immigrants chefs d’entreprise.
