Mass Customization Production Planning & Management System based on Unfulfilled-order-rate with Advance Demand Information -Performance Analysis of Three Indices about Unfulfilled-order-rate -

Abstract

In this paper, we try to model for 'Naiji System' which is a unique corporation between a maker and suppliers in Japan. We propose Mass Customization Production Planning & Management System (MCPS) based on unfulfilled-order-rate by using Advance Demand Information, which is called 'Naiji'. This model is formulated as a nonlinear stochastic programming problem which minimizes the sum of production cost and inventory holding cost subject to the set of probabilistic constraint and some linear production constraints.We propose that (i)the strictly defined indicator of the unfulfilled-order-rate (SOn), (ii) the upper bound to estimate the unfulfilled-order-rate more strictly(SOn(min)), (iii)the indicator of the unfulfilled-order-rate in the case that inventory is independent between each periods and we analyze performance of 3 indicator. We confirm that inventory becomes 7-12% decreases by using the indicator of SOn,comparing with SOn(0). Finally an availability of the indicator and of the procedure is shown.
