In this paper, we consider a single machine scheduling problem with two criteria: minimizing both total flow time with total tardiness and minimize maximum tardiness with number of tardy jobs. Unlike the classical scheduling ...

The logistics sector is one of the most important domains in the service sector in understanding the increasing scale of business activities along with globalization. Due to the nature of the service sector, where competition ...

Purpose The purpose of this study is to explore the presence of ethical standards in the content of international hospitals codes of ethics disclosed in their websites. Design/methodology/approach Firstly, the focus is on ...

When the dynamic environment of ship recycling is considered, many different severe risks may occur. These risks affect different dimensions including people, environment and economic. The aim of the study is give a framework ...

Although the disassembly line balancing problem is one of the intensively studied areas in manufacturing, there is little research from a green perspective. This study therefore proposes an integrated framework that considers ...

Quality of medical and pharmaceutical products has a key role in healthcare systems such as hospitals for better services to patients. This study proposes a comprehensive multi-objective mathematical model in healthcare ...

Today's competitive world is given the critical role of enterprise resource planning (ERP) for coordinating the workflow in companies from different industries. To provide valuable insights into ERP, identifying the critical ...

The aim of this paper is to apply the variable block insertion heuristic (VBIH) algorithm recently proposed in the literature for solving the quadratic assignment problem (QAP). The VBIH algorithm is concerned with making ...

Job satisfaction, in terms of worker's satisfaction, is one of the intensively studied areas in human resource and management. However, there is little information available on how ergonomics and the manufacturing environment ...

In this paper, a memetic algorithm with a variable block insertion heuristic is presented to solve the single machine total weighted tardiness problem with sequence dependent setup times. Together with the traditional ...
