伙伴选择问题正规解的存在性

Existence of Normal Solutions to Partner Selection Problems

基于虚拟企业管理中伙伴选择问题的整数规划模型,从理论上分析了它的性态,证明了其正规解的存在性.在单位时间拖期罚款不小于投资利息的条件下,获得了最佳工期必是预定工期的结论.所得结果对于该类问题的研究与求解以及制定工程拖期罚率提供了理论依据,对实际应用具有重要意义.

Based on an integer programming model for partner selection problems （PSPs） in virtual enterprise management, the properties of the problem are theoretically analyzed and the existence of normal solutions to the PSPs is proved. It is shown that the optimal project span-time must be identical with the stipulated project span-time under the condition that the amount of the project postponement fine in unit time is not less than the interest of capital investment. The resulting conclusion provides a theoretical criterion for the further researches and the solution of PSPs and for determining project postponement fining rate. It is of significance for real application.
