中文摘要 | 集中化序列投資問題(Centralized Sequential Investment Problem; CSIP)旨在考量區域特徵影響下,求得一投資序列使得所有投資區域在最短時間內達至目標營業額 [2, 3];而本文之目的主要在提供一有效的模式參數估計方法,俾利實務上之應用。首先,引用先前文獻之研究假設,並以遞迴式建構更精準之CSIP最終求解模式。再者,提出「區域特徵」影響投資序列之可能情況,進而引用韋伯分佈,發展此模式之參數估計方法。最後,闡述模式參數之相關意涵,以協助實務應用者更加瞭解集中化序列投資模式之應用。 |
英文摘要 | This study focuses on the development of an estimation method of model parameters for centralized sequential investment problem (CSIP). CSIP was proposed by our previous studies [2, 3]. CSIP aims to find an investment sequence under taking into account the regional characteristics effect (RC effect), the following of which would enable all investment regions to achieve the target revenues within the shortest period of time. In formulating this model we take the same assumptions as our previous studies. For improving the precision of our previous model, we use the recursive formula to present the CSIP’s finial form. By introducing the possible scenarios that RC effect on investment sequence, a method based on Weibull distribution to estimate model parameters is proposed for solving CSIP. Also, some relative discussions to the implications of parameters are given to assist the practitioners to understand the CSIP. |
