Vol. 11 No. 2 (2018): July-December
We are grateful to all JOSCM collaborators, associate editors, authors, reviewers and readers from this journal that help us, in many ways, to deliver the second edition of 2018. These eight papers illustrate from different theoretical and contextual perspectives some current topics in Operations Management and Supply Chain Management research such as risk management, international freight prices and health supply chain, among others. The last two papers are part of the Forum SIMPOI, which publishes the best papers from SIMPOI/2018 conference. I hope these papers bring relevant insights and advances for the development of our research area.
The first paper of this edition “Modeling and optimization of multilayer aggregate production planning” is authored by Ridwan Al Aziz, Himangshu Kumar Paul, Touseef Mashrurul Karim, Imtiaz Ahmed, and Abdullahil Azeem. This paper focuses on the determination of production, inventory and workforce levels while meeting the fluctuating demands requirement. The suggested model assumes the physical resources as deterministic and constant. Once the Aggregate production planning is established, constraints are imposed on the production process and assumes the physical resources as deterministic and constant in order to apply the model to enhance productivity and profitability
The second paper “Rudimentary causes and impacts of Supply chain risks in sub-Saharan Africa” is written by Adenike Aderonke Moradeyo. This study is exploratory and aims to highlight supply chain risks, their impacts and mitigation strategies used by manufacturing firms in Nigeria. It presents data from multiple sectors. Findings point out the main causes of supply chain risks, such as: transportation delays, variation in raw material prices and quantities, unexpected customer demands, and constant power outages.
The third paper is called “Do analytically-oriented supply chains better manage risks?” by Murilo Zamboni Alvarenga, Marcos Paulo Valadares de Oliveira, Hélio Zanquetto Filho, and Washington Romão dos Santos. This paper verifies the impact of analytical orientation on supply chain risk management through a survey with micro, small and medium sized Brazilian companies. A structural equation modeling was carried that point out that those supply chains that are more analytical better manage their risks resulting in a lower perception of uncertainty.
Alvarenga, Oliveira, Zanquetto Filho and dos Santos are also the authors of the fourth paper of this edition “Analytical supply chains: Are they more Resilient? A model’s proposition”. Analytical supply chains: Are they more resilient? A model’s proposition. This study is a theoretical essay that aims to present a model that include analytical orientation to recover supply chain interruptions. It proposes an expansion in supply chain resilience model to be tested.
Daniel Dramani Kipo-Sunyehzi is the author of the fifth paper “Principal-agent problems in implementation of Ghana’s health insurance scheme”. This paper analyses principal-agent problems in implementation of National Health Insurances Scheme in Ghana. The relationships between health service providers (agents and health insurance authority) and clients as principals. Results compared private and public health service providers and bring implications for policy that can be expanded for developing countries.
The sixth paper of this issue is called “The Brazilian ocean freight oscillation: The experts’ explanation to the USA, Europe and China trade” authored by Felipe BúrigoBathazar, Marcelo André Machado, and Guilherme Luís Roehe Vaccaro. A panel of experts in charge of pricing international freight analysed ocean freight from and to East Coast of United States, Northern Europe and China to Brazil. The relationship between supply and demand with ocean freight is the most influence for freight rates. The study also points out other variables that are relevant to explain ocean freight oscillation.
The seventh paper “The moderate effect of analytics capabilities on the service quality” comes from the Forum Simpoi is authored by Laís Rocha Vale, Larissa Alves Sincorá and Letícia de Sousa Milhomem. The study focuses on the moderation effect of organizations capabilities in the development and service delivery processes. It contributes proposing relationships between analytics capabilities and the Service Quality model that can be expanded in further research.
The last paper “Sustainable practices in the coffee supply chain in the cerrado mineiro region, Brazil” was also presented at Simpoi 2018 and is authored by Warley Henrique da Silva, Patrícia Guarnieri, and José Márcio Carvalho. It discusses the sustainability in coffee supply chains through sustainable practices and its effects in cerrado mineiro Region, Brazil. A case study carried out with different stakeholders from the coffee chain illustrate the empirical discussion. The paper contributes to understanding the decision-making process by the agents that operate in the coffee supply chain, mainly in the case of producers, cooperatives and development agencies.
I hope you enjoy reading this new JOSCM issue.
