Abstract

Purpose

Robust design is a well‐known quality improvement method that focuses on building quality into the design of products and services. Yet, most well established robust design models only consider a single performance measure and their prioritization schemes do not always address the inherent goal of robust design. This paper aims to propose a new robust design method for multiple quality characteristics where the goal is to first reduce the variability of the system under investigation and then attempt to locate the mean at the desired target value.

Design/methodology/approach

The paper investigates the use of a response surface approach and a sequential optimization strategy to create a flexible and structured method for modeling multiresponse problems in the context of robust design. Nonlinear programming is used as an optimization tool.

Findings

The proposed methodology is demonstrated through a numerical example. The results obtained from this example are compared to that of the traditional robust design method. For comparison purposes, the traditional robust design optimization models are reformulated within the nonlinear programming framework developed here. The proposed methodology provides enhanced optimal robust design solutions consistently.

Originality/value

This paper is perhaps the first study on the prioritized response robust design with the consideration of multiple quality characteristics. The findings and key observations of this paper will be of significant value to the quality and reliability engineering/management community.

Abstract

Purpose

The purpose of this study is to examine the legal framework for court-annexed dispute resolution in courts with Sharī‘ah jurisdiction in Nigeria, Malaysia and Singapore. The major part of the study is dedicated to propose reforms in the administration of justice system in the courts with Sharī‘ah jurisdiction in Nigeria and the relevance of such reforms to the ongoing reforms in the Middle East and North African (MENA) countries.

Design/methodology/approach

This is an integrative literature review, which adopts a comparative approach in analyzing the conceptual framework of amicable dispute resolution in the modern world with particular reference to the Sharī‘ah court.

Findings

The findings of this research illustrate the adaptability of the practices in Malaysia and Singapore in the courts with Sharī‘ah jurisdiction in Nigeria and the MENA region.

Practical implications

An exposition of the dispute resolution processes in Islamic law reveals the relevance of these processes in modern reforms of the administration of justice system. The practical implications of this study include the streamlining of the rules and procedures of modern Sharī‘ah courts in post-revolution Arab countries to allow for court-annexed amicable (alternative) dispute resolution initiatives.

Originality/value

As far as it is known, this is the first conceptual study on the court-annexed dispute resolution frameworks of Sharī‘ah courts in three commonwealth jurisdictions.
