The agile manufacturing is a new conception for rap id reaction to the consumers. 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.
