Similar Cost

In order to be cost competitive in the consumer electronics industry, it is needed to estimate product costs earlier in the design phase. In this study, we reviewed quality and quantity cost estimation techniques to develop a cost estimation system. The qualitative cost estimation technique is used to store expert's knowledge in the form of rules or a decision tree, and quantitative cost estimation techniques is used to extract a similar cost basis based on historical cost data of products. Also, we developed a cost comparison system using these two methods.

Competitive Nature

Due to the highly competitive nature of businesses today, cost estimation forms an important strategic process in making decisions about design and development of new products. It is advantageous to be able to estimate the product costs early in the product development cycle. In this paper, products' cost structure based on the feature is proposed by analyzing product cost, and the calculation methods of manufacturing cost is introduced. By means of parametric designing capability, functional frame of cost estimation system is built on the basis of the secondary development technique of SolidWorks. Taking certain type of hydraulic support as an example, the software prototype of cost estimation is developed. The result of cost estimation accords with actual product cost prove the feasibility of cost estimation method based on the secondary development of SolidWorks.

Purpose This paper aims to propose an intelligent system that serves as a cost estimator when new part orders are received from customers. Design/methodology/approach The methodologies applied in this study were case-based reasoning (CBR), analytic hierarchy process, rule-based reasoning and fuzzy set theory for case retrieval. The retrieved cases were revised using parametric and feature-based cost estimation techniques. Cases were represented using an object-oriented (OO) approach to characterize them in n-dimensional Euclidean vector space. Findings The proposed cost estimator retrieves historical cases that have the most similar cost estimates to the current new orders. Further, it revises the retrieved cost estimates based on attribute differences between new and retrieved cases using parametric and feature-based cost estimation techniques. Research limitations/implications The proposed system was illustrated using a numerical example by considering different lathe machine operations in a computer-based laboratory environment; however, its applicability was not validated in industrial situations. Originality/value Different intelligent methods were proposed in the past; however, the combination of fuzzy CBR, parametric and feature-oriented methods was not addressed in product cost estimation problems.
