One of its implements is establishing a virtual ente rprise (VE) around the task, where each manufacturing unit, or sub-task, probab ly have at least one resource, or referred to as suppliers. Because each manufac turing unit might be carried out in different geographical places that implies t his probably gives rise to transportation cost, the selection of resources for e ach manufacturing unit must considers not only the manufacturing price of each r esource but also the transfer cost between any two potential resources. This pap er discusses the resource reconfiguration problem with two hypotheses: 1. Permit s one or more resources to attend the same manufacturing unit as long as the tot al cost can reach its least; 2. The freight contains the initial part, that is t he freight concave. Indeed, these hypotheses are much meaningful in the real wor ld. Furthermore, to simplify the solution for this problem, we propose two conce pts: assembly tree (AT) and combinatorial mode base (CMB). Formally an AT is a c omplete production line, which can ensure the parts equilibrium, and its capacit y is subjected to the least capacity of every resources and every path in it. In the end, we propose an implicit enumeration algorithm (IEA) by the use of CMB, including it is a heuristic algorithm for integer programming (HAIP) by the use of AT. The IEA can be outlined that for a determined combinatorial mode, if it h as not enumerated, we use the HAIP to get an near optima and corresponding CMB, marking every combinatorial mode extended from the CMB as enumerated, other cont inue a new iteration. The HAIP can be outlined that for a determined combinatori al mode, there are some determined number of AT, we select an AT with the le ast slope, and select the volume of this AT to its ultimate within its capacity, iterates this doing until the needed volume reached. In the end, we conclude th is paper and prospect the deep research based on GA thought.展开更多

However, as the manufacturing system evolves into more and more complicated net work relationship, the fundamental concepts of manufacturing strategy focusing o n a product family and bridging its market, competition and factory system have rarely been adapted to face new challenges from extended system, although the st rategy formation processes are widely discussed from both perspectives in terms of top-down and bottom-up. Coming into the new economy, as manufacturing industry and system have changed their role in both company and society, manufac turing, especially physical fabrications and assembly, has become less critical than ten years ago, and the compatible manufacturing strategy has been also chal lenged by the new rules based on knowledge development and by the new business m odel based on value creation. Manufacturing strategy has to find a position and mechanism contributing itself to the corporate strategy and competitive advanta ge. This paper seeks to answer the question what networked manufacturing systems can imply to the manufacturing strategy, by clarifying some key challenges to the c lassical manufacturing strategy theory, especially from networked manufacturing system and value-based manufacturing strategy perspectives. The paper is based on some preliminary case observations in several multinationa l corporations in aerospace, automotive, engineering and electronics industries. Original objectives are targeted on an evolutionary process of manufacturing system from factory-based system towards globally collaborated inter-firm netw ork, seeking to explain why manufacturing companies evolve into more and more un controllable relationship. The preliminary findings are seriously challenging t he traditional concept of firm and the theory manufacturing strategy developed b y Skinner (1969). Some key findings from the preliminary work include: - value creation is more dependent upon a proposition in the value net than crea tion of competitive edge for existing product line-which ask manufacturing stra tegy should focus more on a higher value - in manufacturing system, leveraging other companies resources seems to be more important than owning these resources - which implies networked virtual enterpr ise is preferred architecture - in inter-firm collaboration, understanding the dynamics and keeping a balance are more and more critical in the spectrum of collaboration from one end of cor porate hierarchy towards another end of free market-which means that a cont ingency picture is more needed than a single supply or virtual network model - from evolution perspective, deeply understandings about internally vertical in tegration, outsourcing, sub-contracting, and manufacturing hollowing-out are n ow more and more important than the single competence knowing how to do them-wh ich means an up-grading towards know-why These new challenges ask new solutions for industry. They imply not only new sy stem architecture of manufacturing system based on an inter-firm relationship b ut new strategy process with a context-based contingency framework. The paper summaries some existing researches and develops a theoretical framework for the new networked manufacturing system. As a preliminary case study, the paper also suggests a further research plan in the future.展开更多
