快时尚品牌产品开发流程对时间绩效的影响

Influence of product development process of fast fashion brand on time performance

针对快时尚产品开发流程的时间绩效问题,以快时尚品牌S为实际案例,对产品开发流程进行系统动力学建模,构建了仿真实验平台。采用"战略-资源-绩效"的基本框架,对流程的7个主要变量进行资源配置的仿真实验,预测了周期时间、准交率和平均产能等3个关键绩效指标(KPI)的仿真估计值。使用局部灵敏度分析和熵值法,确定周期时间、准交率和平均产能等KPI指标的权重系数,分别为53.5%、2.7%和43.4%。根据权重系数和S品牌的时间竞争战略,对流程的时间绩效进行综合评价。研究发现,批量、服装设计速率、面料重复使用率和面料生产速率等变量对流程的时间绩效影响较大。当S品牌的企划确认批量减少约25%时,整体时间绩效最优。

To solve the issue of time performance in fast fashion product development process,this paper constructs a system dynamics model of product development process based on the practical case of a fast fashion brand S,and build a simulation experiment platform. With the basic framework ＂strategyresources-performance＂, the simulation experiments of resource allocation are carried about 7 key variables in the process flow, and the simulation estimated values of three key performance indicators（ KPI）, such as cycle time, delivery rate and MEAN flow, are evaluated. Using local sensitivity and entropy method,weight coefficients of cycle time,delivery rate and MEAN flow are recognized as 53. 5%,2. 7% and 43. 4%. According to weight coefficients and time-based competition strategy of brand S,time performance of process is evaluated comprehensively. The research shows that variables of batches,rate of designing clothing and fabric repeat usage have a great effect on the time performance of the process flow. When layout batches reduce by about 25%,the total time performance is optimal.
