The purpose of this paper is to investigate the performance of unpaced reliable production lines that are unbalanced in terms of their mean operation times, coefficients of variation and buffer capacities.

Simulations were carried out for five‐ and eight‐station lines with various buffer capacities and degrees of means imbalance. Throughput, idle time and average buffer level performance indicators were generated and statistically analysed.

The results show that an inverted bowl allocation of mean service times, combined with a bowl configuration for coefficients of variation and a decreasing order of buffer sizes results in higher throughput and lower idle times than a balanced line counterpart. In addition, considerable reductions in average inventory levels were consistently obtained when utilizing a configuration of progressively faster stations, coupled with a bowl‐shaped pattern for coefficients of variation and an ascending buffer size order.

The results for these specific experiments imply that resources expended on trying to achieve a balanced line could be better used by seizing upon possible enhanced performance via controlled mean time, variability and buffer imbalance. Results are valid for only the line type and parameter values used (simulation results are specific and not general).

Guidelines are provided on design strategies for allocating labour and capital unevenly in unpaced lines for better performance in terms of increased throughput or lowered idle time or average buffer levels.

This paper might be viewed as one of the first simulation investigations into the performance of unpaced production lines with three sources of imbalance.

The purpose of this paper is to introduce sequence‐dependent disassembly line balancing problem (SDDLBP) to the literature and propose an efficient metaheuristic solution methodology to this NP‐complete problem.

This manuscript utilizes a well‐proven metaheuristics solution methodology, namely, ant colony optimization, to address the problem.

Since SDDLBP is NP‐complete, finding an optimal balance becomes computationally prohibitive due to exponential growth of the solution space with the increase in the number of parts. The proposed methodology is very fast, generates (near) optimal solutions, preserves precedence requirements and is easy to implement.

Since development of cost effective and profitable disassembly systems is an important issue in end‐of‐life product treatment, every step towards improving disassembly line balancing brings us closer to cost savings and compelling practicality.

This paper introduces a new problem (SDDLBP) and an efficient solution to the literature.

It is well-reported that financial and investment sectors of the economy have grown in recent years, but also that problems of corruption, both institutional and venal, are present. Within the sector, financial auditors and investment consultants have been entrusted to work with and for those for whom financial sector stability and adequate financial returns are crucial. However, these two professions have too often served as handmaidens of corruption. This chapter reviews the history of financial auditing and investment consulting and outlines areas in which corruption manifests. It argues for an end to corruption and it asserts that the two professions could and should be the core of an uncorrupted robust system of financial practice and regulation. Such an arrangement could safeguard a world in which investment business practices are sustainable, honest, and truly productive.

Given its social importance, Sport (especially Football), which has experienced an astounding transformation into a global industry with significant economic impact, has been a vehicle for the transmission of cultural and universal values. Its structural complexity (players, transfer agents, clubs and its owners, right holders of different contracts) creates a lot of moving parts that can easily hide illicit activity, especially because this structure incorporates the international market. The movement of large amounts of money, the difficulty in accounting for all transactions, and ironically, the clubs’ own financial needs increase this sector’s vulnerability to organized crime. For many years, this sector has had a relatively free hand in its efforts to make criminal assets legal. This is made possible by some ineffectiveness of current national and international laws and enforcement bodies, which have not kept pace with the changing situation. It is already known that sport historically has been used as a tool for enrichment of a specific group of companies, an issue deserving of public concern. This chapter argues for a sensitive situation involving the actors of the public and private sectors, notably its regulations, in order to curb corruption and money laundering through sport. The purpose is to address these matters by identifying the risks of misconduct within sport organizations, and proposing measures that could prevent, hamper, and punish any attempts to thwart these organizations’ main goal: promoting sport as a way for cultural improvement and teaching people the values of tolerance and civilized coexistence.

The principal issue that will be considered in this chapter is how the banking sector facilitates the crimes of money laundering and tax evasion. This will entail asking a series of related questions. Does the assistance of the banking sector in financial crime involve a small number of wayward employees at the periphery of banking? Or are multinational financial institutions willing participants in the systemic evasion of global antifinancial crime standards? In exploring these questions, the theory and practice of money laundering will be explored by focusing on the three stages of the money laundering cycle. The global anti-money laundering standards that apply to the banking sector, and the role of bank secrecy in promoting tax evasion, will be examined through a series of case studies. It will be argued that there is strong empirical evidence that the banking sector is a systemic offender facilitating financial crimes, despite the enactment of international and national antifinancial crime standards and criminal prosecutions of financial institutions.

Informal payments in health care exist in many countries around the world. However, the prevalence of informal payments varies between countries. A distinction between illegal or unethical informal payments like bribes and corruption, and legal and ethical forms of informal payment like giving gifts is not always easy to make. Illegal and unethical practices include, for example, buying medical certificates, bid rigging during procurements, or selecting service-providers for a hospital based on personal connections. A conceptual global definition of informal payments in health care is not feasible because informality depends on local regulations, values, and traditions. In this chapter, we provide an up-to-date understanding of informal payments in health care (including corruption, fraud etc.) by distinguishing micro, meso, and macro levels of informal payments. We argue that informal payments that occur at these levels cannot be unified under one umbrella of corruption because the various forms of informal payments in health care differ in nature, scope, and damaging effects.

Using the pharmaceutical sector as a microcosm of the health sector, we highlight the most prevalent structural and policy issues that make this sector susceptible to corruption and ways in which these vulnerabilities can be addressed. We conducted a literature review of publications from 2004 to 2015 that included books, peer-reviewed literature, as well as gray literature such as working papers, reports published by international organizations and donor agencies, and newspaper articles discussing this topic. We found that vulnerabilities to corruption in the pharmaceutical sector occur due to a lack of good governance, accountability, transparency, and proper oversight in each of the decision points of the pharmaceutical supply chain. What works best to limit corruption is context specific and linked to the complexity of the sector. At a global level, tackling corruption involves hard and soft international laws and the creation of international standards and guidelines for national governments and the pharmaceutical industry. At a national level, including civil society in decision-making and monitoring is also often cited as a positive mechanism against corruption. Anticorruption measures tend to be specific to the particular “site” of the pharmaceutical system and include improving institutional checks and balances like stronger and better implemented regulations and better oversight and protection for “whistle blowers,” financial incentives to refrain from engaging in corrupt behavior, and increasing the use of technology in processes to minimize human discretion. This chapter was adapted from a discussion piece published by Transparency International UK entitled Corruption in the Pharmaceutical Sector: Diagnosing the Challenges.

Using a general model of corruption that explains and accounts for corruption across professions and institutions, this chapter will examine how certain practices in the media, especially in areas where journalism, advertising and public relations regularly intersect and converge, can be construed as instances of corruption. It will be argued that such corruption, as in the case of cash-for-comment scandals, advertorials, infomercials, and infotainment, as well as public relations media releases disseminated misleadingly as journalistic opinion, is regular, ubiquitous, and systematic.

In this chapter, the nature and extent of corruption in the construction industry is considered from a worldwide perspective, but particularly in the context of research conducted in South Africa. The definition of corruption is expanded to include conflict of interest and unethical conduct. Corruption in the construction industry is found to be universal and pervasive, occurring in all areas, at all stages, at all levels, and in all forms. A simple triangular model of corruption is replaced by a more complex four-dimensional risk-based model. The challenge for the construction industry, in combating corruption, will essentially require multilateral action in all four dimensions of the enhanced model: eliminating and reducing opportunities where possible; relieving the pressures to commit corrupt acts; rebutting the rationales and arguments used to excuse corruption; and substantially improving and innovating more forensic methods of detection. While the decision to engage in corruption is risk-based, particularly in terms of the capacity to evade detection; in essence corruption is a cultural and moral issue for society.

In 2012, the New York Department of Financial Services threatened to revoke Standard Chartered Bank’s U.S. license for alleged money laundering violations involving Iran. The bank’s settlement with US regulators and law enforcement cost the bank approximately $1.099 billion. In 2013, as a signal that no bank was too big to jail, the Holding Individuals Accountable and Deterring Money Laundering Act was introduced into the U.S. Congress. We focus on a clinical examination of the Standard Chartered money laundering case and examine the role of the US regulators and law enforcement in the settlement.
