Abstract

Purpose

This paper treats the problem of scheduling seafaring staff inspired from a real case study, where the shipowner operates several vessel categories that require specific skills aiming to achieve a fair workload distribution and minimizing incompatibility between workers while meeting legal constraints, including requirements for days off and rest intervals between shifts.

Design/methodology/approach

A mixed integer linear problem (MILP) formulation has been built to address the seafaring staff scheduling problem by integrating multiple objectives and constraints. The model’s performance is tested through experimental results across varying parameter adjustments.

Findings

Our model was tested and validated using the XPRESS solver, and the results demonstrate its effectiveness in meeting the specified objectives and constraints. Notably, findings reveal that increasing the number of qualified workers leads to improved gains, until a certain threshold. Additionally, expanding the size of the workforce can result in longer execution times, specifically when incompatibility increases.

Originality/value

The originality of this study lies in proposing a generic novel model that deals with maritime staff scheduling, incorporating worker incompatibilities and workload fairness as key objectives.

Abstract

Purpose

The purpose of this paper is to scrutinise the intricate relationship between the inadequate enforcement of anti-corruption laws and the application of good governance and the persisting prevalence of coups d'état and poverty in Africa.

Design/methodology/approach

This paper uses a doctrinal legal research approach, synthesising existing literature while extensively analysing primary and secondary legal sources. Its primary aim is to scrutinise the intricate relationship between the inadequate enforcement of anti-corruption laws and the application of good governance and the persisting prevalence of coups d'état and poverty in Africa. The choice of case study countries Burkina Faso, Chad, Gabon, Guinea, Mali, Niger and Sudan stems from their historical significance, regional diversity, data accessibility and potential insights into the interplay among anti-corruption enforcement, governance, poverty and coups d'état in Africa.

Findings

The enforcement of anti-corruption laws and the promotion of good governance are indispensable for democracy and economic stability; their suboptimal enforcement directly contributes to coups d'état and the worsening of poverty in African nations. It emphasises the imperative for African countries to consistently and proficiently enforce anti-corruption laws and adhere to principles of good governance, effectively and responsibly, to mitigate coups d'état and alleviate poverty in the region.

Originality/value

This study designs a model strategy for combating coups d'état and corruption in Africa as contribution to knowledge in the field of study.
