Abstract
Purpose
The purpose of this paper is to develop an economic model, which could determine the acceptance sampling plan that minimizes the quality cost for batch manufacturing.
Design/methodology/approach
The authors propose a variable sampling plan based on one-sided capability indices for dealing with the quality cost requirement.
Findings
The total quality cost is much more sensitive to process capability indices and inspected cost than internal and external failure costs.
Research limitations/implications
The experimental data were randomly generated instead of real world ones.
Practical implications
The proposed model is specifically designed for manufacturing industries with high sampling cost.
Originality/value
The one-sided capability indices were utilized for the first time to be suitable for the purpose.

Abstract
Purpose
This paper aims to identify ways to establish an information system to aid users to enhance the effectiveness of self-regulated learning and solve the problem of learning domain unawareness. Many libraries are spacious and with a rich collection of books, the problem a newcomer may encounter in the wide library is spatial unawareness. In addition, people new to a particular field of study often encounter the problem of learning domain unawareness.
Design/methodology/approach
This paper presents an overview of self-regulated learning theory first. We realize the essential principles of self-regulated learning model in the library and developed a learning system that utilizes the concept of combining mobile augmented reality (AR), indoor navigation and data mining algorithms.
Findings
The proposed NO Donkey E-learning (NODE) system utilizes AR and innovative indoor positioning technology to fulfil the goal of navigation inside a library and solve the problems of spatial and learning domain unawareness. On the one hand, the system allows peers to communicate asynchronously to create a cloud-based information sharing community; the dual-track terminal (the website and the app interfaces) in the system could provide both educational functionalities and mobility for readers. On the other hand, AR navigation function integrates the information of reading paths, the real-space locations, real-time dynamic information, book introductions and readers’ comments to help readers have access to the topic-related books efficiently.
Practical implications
We found that although the library provides the floor plan and signs, such passive and fixed indication may cause spatial unawareness. People need system to show the bookshelf location and dynamic direction indicators when they walk in the wide library. However, most existing library information systems only provide readers with the function of book search, including which floor the book is on, call number and check-out status. In this sense, we propose that self-regulated learning theory integrated the new innovation technology is the solution for the above issues.
Originality/value
The system developed in this study, while viewing the real scenes inside the library through camera lens, provides related virtual educational information services and learning paths on screen and guides the public to do systematic self-regulated learning. With the functions of the “learning topic” and “knowledge sharing”, the learning system promotes the general public to self-monitor their learning progress and to use the sharing mechanism as the system structure to solve the two main problems of spatial unawareness and domain unawareness in learning in libraries, creating a truly innovative people-centred library information system.

Abstract
Most previous studies concerning company performance evaluation focus merely on operational efficiency. Operational effectiveness, however, which might directly influence the survival of a company, is usually ignored. As a result, this paper presents a study which uses an innovative two‐stage data envelopment analysis model that separates efficiency and effectiveness to evaluate the performance of 41 listed corporations of the banking industry in Taiwan. The empirical result of this paper is that a company with better efficiency does not always mean that it has better effectiveness. There is no apparent correlation between these two indicators.
