Determining the Optimum Process Mean for an Indirect Quality Characteristic
نویسنده
چکیده
The distribution of quality characteristic of a product is usually assumed to be known. In some situation, the quality characteristic of a product cannot be measured directly. It needs to be measured by controlling another factor. Wen and Mergen (1999) presented a method for determining the optimum process mean in order to minimize the expected total loss of a product. However, they have not considered the quality loss for a product within specification in the model. In this paper, we will propose a modified Wen and Mergen’s (1999) model taking into account an indirect quality characteristic with the quadratic or linear asymmetrical quality loss of a product within specifications.

Optimum target value of multivariate processes with unequal non-conforming costs
In quality control charts, the problem of determining the optimum process mean arises when the deviation of a quality characteristic in one direction is more harmful than in the opposite direction. The failure mode in these two directions is usually different. A great majority of researches in this area have considered asymmet-ric cost function for processes with single quality characteristics....
متن کاملAbsorbing Markov Chain Models to Determine Optimum Process Target Levels in Production Systems with Rework and Scrapping
In this paper, absorbing Markov chain models are developed to determine the optimum process mean levels for both a single-stage and a serial two-stage production system in which items are inspected for conformity with their specification limits. When the value of the quality characteristic of an item falls below a lower limit, the item is scrapped. If it falls above an upper limit, the item is ...
متن کاملSimultaneous Optimization of Production and Quality in a Deterioration Process
Achieving optimal production cycle time for improving manufacturing processes is one of the common problems in production planning. During recent years, different approaches have been developed for solving this problem, but most of them assume that mean quality characteristic is constant over production run length and sets it on customer’s target value. However, the process mean may drift from ...

متن کاملDesigning an Economic Repetitive Sampling Plan in the Presence of Two Markets
In this paper, we develop an optimization model for the economic design of repetitive sampling plan in the presence of two markets. The process under consideration produces a product with a normally distributed quality characteristic with unknown mean and known variance. The quality characteristic has a lower specification limit. The quality of the product is controlled via lot-by-lot acceptanc...
