Objective: This study proposes a decision model for evaluating sustainable supplier development programs (SSDPs) using the HFLTS-QFD technique, which is a combination of Hesitant Fuzzy Linguistic Term Sets (HFLTS) with the Quality Function Deployment (QFD) method. Theoretical Framework: The implementation of supplier development programs is important to improve supplier performance in aspects related to economi...
This work aims to establish assertive inventory policies for the raw materials in a Portuguese bakery. The demand behaviour of some items was analysed, using the ABC classification, and 14 main items were prioritised. Using Holt-Winters’ additive method, the demand for these items was forecast until the end of 2023. With these forecast data, the paper presents a simulation and comparison between two different in...
The present study brings forward a simulation-based study of the production process of a Portuguese bakery. The main goal is to analyse different production processes and propose improvements, through the use of discrete event simulation. A relevant set of data was collected, and four productive processes were selected to be modelled using Simio software (Simulation Modelling based on Intelligent Objects). The a...
The automotive industry deals with complex processes. Becoming aware of the importance of agile management they are contributing to a creative fusion known as “leagile”. However, this concept needs further study and investigation. This work presents a systematic literature review on Lean Agile implementation in the automotive industry. Thirty-three publications were reviewed and characterized according to the y...
The XXI Congress of APDIO, the Portuguese Operational Research Society, took place on 7 and 8 November 2021, with more than 120 registered participants and around 80 papers submitted. This congress took place at a very particular historical moment. After the first waves of the COVID-19 pandemic, which had immobilized humanity, cancelling all gatherings, society was equipped with the first effective weapons agai...
The present and future digital transformations of industry 4.0 set a high skill requirement for workers. This skill requirement calls for upskilling, a change in job profiles, and lifelong learning, both for the worker, the workplace, and society in general. However, for upskilling activities to leave a lasting impact on the behaviour and skills of the worker, the upskilling needs to be authentic, relevant, and...
The main objective of this study is to analyse different production scenarios of a company, and propose improvements with the use of discrete event simulation. We use a simulation tool, SIMIO software, to reproduce the existing production layout of the company. Our purpose is to gather relevant information about the actual production system behaviour, and to find strategies to increase the production level to m...
Industry 4.0 comprises the application of different technological solutions so that business processes throughout the production chain are integrated. The supplier’s selection, considering the industry 4.0 requirements, is essential in promoting collaborative strategies between suppliers and manufacturers. In this context, this study presents a systematic literature review about quantitative models to support s...
Industry 4.0 is promoting the digitisation of manufacturing sectors towards smart products, machines, processes and factories. The adoption of disruptive technologies associated to this industrial revolution is re-shaping the manufacturing environment, decreasing low-skilled activities and increasing high-skill activities. These technological trends are affecting the job profiles and the skills required by the ...
The present study brings forward a simulation-based study of the production process of a Portuguese company that produces a wide range of bread. The main objective of this study was to analyse the different production processes of the company, and to propose further improvements to these, through the use of discrete event simulation. A relevant set of data was collected and four productive processes were chosen...
