可重构制造系统成本模型
Cost Model for Reconfigurable Manufacturing System
【摘要】 分析了可重构制造系统的时间要素和成本构成,给出了成本构成模型。定义了节约因子α_i、残留因子λ_i和时间价值因子σ_T,α_i表示重构固定投资C_i和初始固定投资C_O间的关系,λ_i表示固定投资未来价值与现价值间的折旧关系,σ_T表示未来投入成本的折现关系。分析了α_i与C_i的关系,给出了5种生产需求下的C_i模型。最后建立了可重构制造系统近似成本模型,并进行了影响因素趋势分析。
【Abstract】 Time and cost compositions of a reconfig-urable manufacturing system (RMS) were analyzed, andthe cost compositions models were given. Economical fac-tor α, salvage factor λ, and time value factor σ_T were de-fined to express the relationship between additional fixedinvestment C_i and initial fixed investment C_o,the rela-tionship between final and present value of fixed invest-ment and the discount relationship of a kind of invest-ment, respectively. The relationship between economicalfactor α, and additional fixed investment C_i was analyzed.Five models for additional fixed investment C_i were builtbased on five kinds of production requirements dependingon the production capacity of a RMS. An approximationcost model for RMS was built based on all models builtafore. Several conclusions that may be used to the strate-gic investment decision--making in the configuration andreconfiguration of RMS are drawn on the whole after theanalysis of related parameters included in the approxima-tion cost model.
