This study examines an imperfect production and inspection system with customer return and defective disposal. We develop an optimal lot sizing model with production and inspection quality investment, incorporating all the quality costs. We find the optimal lot size, rework frequency, defective proportion, and Type I and Type II inspection error proportions which minimize the total quality cost...

LTHOUGH reuse is assumed to be especially valuable in building high-quality software, as well as in OO development, limited empirical evidence connects reuse with productivity and quality gains. The authors' eight-system study begins to define such benefits in an OO framework , most notably in terms of reduced defect density and rework, as well as in increased productivity.

Software inspections are a software engineering “best practice” for defect detection and rework reduction. In this paper, we describe our initial empirical evaluation with using a tool aiming to provide Internet groupware support for distributed software inspections. The tool is based on a restructured inspection process to reduce synchronization and coordination problems.

Abstract Project completion behind schedule is a struggle for the construction sector, affecting time, cost, and quality. This investigation has been necessitated by lingering nature of project delay risks despite many extant analyses. study collated expert opinions from Thai sector on salient variables their influence each other DEMATEL-SD analysis. The data were analysed found consistent with...

Purpose – The purpose of this paper is to propose a new temporal disaggregation method for time series based on the accumulated and inverse accumulated generating operations in grey modeling and the interpolation method. Design/methodology/approach – This disaggregation method includes three main steps, including accumulation, interpolation, and differentiation (AID). First, a low frequency flo...
