Developing an Add - in Decision Model for Collaborated Production Planning in Enterprise Resource Planning Systems

企業資源規劃系統協同生產銷售決策模式之研究

企業資源規劃（ERP）系統可做為整合企業資源配置、規劃與管理的平台。目前時下所提供的ERP系統都過於簡化，以致在實務上存有嚴重的缺點。例如，在ERP系統的規劃參數不是固定就是隨意選取，造成參數的設定很少是有效；且在一般的系統設定上生產產能都被假設為無限。本研究發展一套ERP系統附加決策模式，以改善生產規劃之靜態參數設定與市場之動態特性間的差距。本研究所發展之模式同時考量動態環境下生產時程、批量與價格，使後端生產決策更能反映前端市場變化。再者，本模式考量到產能的有限性，以彌補傳統ERP系統設定上的不足。本研究最後根據推導出的模型作數值分析，深入探討各重要參數與獲利間之關係。

ERP systems can provide a platform for the integration of plant and enterprise resource allocation, planning, and management. Currently available systems in the market are yet fairly simplistic that results in serious inherent weaknesses in practice. For example, the planning parameters are arbitrarily selected, fixed, and rarely validated, and production capacity is assumed unlimited in typical system settings and implementation of ERP systems. In this paper, an add-in decision model is developed that closes the gap between the static parameter settings in production planning and dynamic nature in the marketplace. The proposed model jointly considers the production schedule, lot-size and the periodic pricing in a dynamic environment that makes the back-end production decision more responsive to the front-end changing market. Further, the model takes limited capacity into account which remedies the traditional ERP system settings.
