Computer-aided tool cost estimating: an evaluation of the labour content of injection moulds
描述了一家英国模具公司与大学合作，改用基于计算机的注塑模具成本估算系统，重点评估模具制造中的劳动含量，通过形状和结构分析及聚类回归得出估算。
The accurate cost estimation of major production tools, such as for presswork or injection moulding, is important for successful toolroom management. This paper describes how a British tool-making company, working with a university department, is changing to a computer-based tool cost estimating system for injection moulds. The new system is mainly concerned with the labour content of tool manufacture. It uses component shape and tool structure analyses based on conventional coding principles. The resultant data base is classified and subdivided by cluster analysis. Estimates are then derived by multiple linear regressions which use the relevant cost characteristic tool group.
