In this work we present a tabu search metaheuristic method for solving the permutation flow shop scheduling problem with sequence dependent setup times and the objective of minimising total weighted tardiness. The problem is well known for its practical applications and for the difficulty in...

In rotating machines, shaft and bearing are the critical components of interest for fault diagnosis. In recent years, the application of machine learning for fault diagnosis is gaining momentum. This paper presents the fault diagnosis of shaft and bearing using support vector machine (SVM). The...

The free disposal hull (FDH) models are used as an alternative to data envelopment analysis (DEA) models for performance measurement and efficiency assessment. The conventional FDH models are used to evaluate the performance of a set of firms or decision-making units (DMUs) using deterministic...

The Gini coefficient has been widely used to measure the performance of rare event targeting models. Although it is a good performance measure when the scores and hits are proportionally associated, it fails to address the possible non-linear distribution of targeting scores and neglects the...

The increasing complexity in workflow management systems (WMSs) has led to greater vulnerability due to system failure. Although system vulnerabilities cannot be completely eliminated, the accidental or anticipated failures have to be thoroughly understood and guarded. Traditionally, the failure...

In practice, during the system requirements gathering phase, the focus is often on the functional requirements of the system, while non-functional requirements are often captured by system analysts at a very global level. The European ECSS series of standards for the aerospace industry includes...

Adaptive sample size and sampling intervals schemes have been widely used to improve the statistical efficiency of Hotelling T² control chart in detecting small changes when the quality of a product or a process can be characterised by the multivariate distribution of quality characteristics....

This study compares the robustness of conjoint analysis versus multiple linear regression when using orthogonal data. The explained variance (R²) by four independent variables was utilised to test the robustness of the regression analysis while Pearson's R and Kendall's tau were used for...

Tourist satisfaction refers to the emotional state of tourists after exposure to the opportunity or experience. Experience can be regarded as the individual's intention to create a situation whereby he gains satisfaction. As a result, a tourist's satisfaction is determined by factors or criteria...

This study aims to gain insight into criteria (detailed market study, business/financial analysis, business/financial analysis before promotion, resource allocation) that contribute to the success of new service development (NSD) ventures in sectors of tourism economy and focusing especially on...
