Metrics for data accuracy improvement in a production scheduling software: An application in the Brazilian Meat Industry

Title: Metrics for data accuracy improvement in a production scheduling software: An application in the Brazilian Meat Industry.

Abstract: This study aims to develop a method for improving the data accuracy of a specific production scheduling software for the meat industry. The proposed method was based on the results obtained in the implementation phase of the scheduling tool in Empresa Alfa, that produces food based on chickens, turkeys and porks. The research method used was a case study, by means of which the influence of data accuracy on the information generated by the system during the project is reported and analysed. The development of the proposed method was based on the theoretical framework on production scheduling, data quality and information quality, the author's perceptions about the project which was applied in the case study and the contributions of experts in the subject of the work. The method was structured in processes and subprocesses, hierarchy that enabled the implementation of the objectives of each process regarding the data accuracy in stages (subprocesses).

An approach to structuring and conducting workforce planning projects

Title: An approach to structuring and conducting workforce planning projects.

Abstract: Building on a study of quantitative and qualitative approaches to workforce planning, a structure and a set of steps are proposed for conducting workforce planning projects in organizations. This approach contemplates four styles of governance applicable to a workforce planning project and the combinations (centralized or decentralized) to be used in the process of reaching decisions in the various difference organizational units. Its structure also comprises the sequencing necessary for workforce planning, as well as the various elements that make up each of the steps. Lastly, its application leads to the systematic construction of an information base that can contribute to enhancing the assertiveness of workforce planning decision making.

Value analysis and value engineering: case study in services

Title: Análise de valor e engenharia de valor: estudo de caso em serviços. (Value analysis and value engineering: case study in services).

Abstract: The aim of this article was to report a structured application of value analysis in the negotiation cell of the Supply Department of a company in the agro-industrial sector. The application object was services provided. Usually, the method is applied to goods. The research method was a single case study. The functions performed by the professionals of the cell were identified, the costs to perform these functions were analyzed and these functions were classified according to their importance. The comparison of the importance with the cost of these functions made it possible to identify opportunities for cost reduction and process optimization in functions where their costs are greater than their importance, eliminating unnecessary activities that do not add value and directing efforts to more important adding value activities. Ideas and proposals were raised for improvements in the processes. After discarding the unviable ideas, viable ones were detailed and specified for presentation and deployment. With the proposal, it is expected to have a sensible reduction in activities that do not add value or cost reduction in activities that now add more cost than value.

Foreseeing Iron Ore Prices Using System Thinking and Scenario Planning

Title: Foreseeing Iron Ore Prices Using System Thinking and Scenario Planning.

Abstract: In competitive and complex markets such as the commodities one, having the ability of planning scenarios and envisioning the behavior of prices in each of them, constitutes a competitive advantage for organizations. Within this context, this research aims at developing a method for the understanding of the key factors that impact the pricing of commodities through a systemic approach, allowing the estimation/evaluation of future prices in different scenarios. Action research was used as research methodology, which is characterized by the principles of collaborative and continuous learning. In order to implement the objectives of this research, an adaptation of the Systems Thinking and Scenario Planning method was developed and implemented in an industry of the iron ore market. The first phase led to the understanding of the main variables associated to the price; in the second phase, this learning was materialized in a system dynamic computational model, which was used in the third and final stage for the estimation/evaluation of future prices in some alternative scenarios. Interviews were conducted in parallel with the quantitative evaluation, in order to obtain subsidies for acceptance and refinement of the proposed method. The results obtained, the learning reported and the possible applications identified for the use of the model indicate that the proposed method allows for the understanding of the pricing of commodities through the systems thinking and the planning by scenarios.

Design Science Research: a research method to production engineering

Title: Design Science Research: método de pesquisa para a engenharia de produção. (Design Science Research: a research method to production engineering).

Abstract: This paper aims to contribute to the Brazilian community of Production Engineering addressing the need to adopt a research strategy focused on the evolution of Production Engineering as a Design Science (DS) showing its effects and process. A theoretical and conceptual methodological approach based on an extensive literature review was used. The literature review showed that the concepts of the methodology proposed associated to Design Science Research (DSR) are relevant and can be applied to Production Engineering. The present study presents a review of DS and DSR concepts stressing the importance of defining the classes of problems and the artifacts to solve them. It also suggests appropriate steps to conduct DSR in Production Engineering context. To deepen the understanding of the meaning of DSR, this article also makes analyses and comparisons between DSR, Case Study, and Action Research in order to clarify the main differences between these methods. Finally, this study makes some remarks on the application of DSR methods and the validation of DSR results.
