Improving urgency-based backlog sequencing of jobs: an assessment by simulation

When order release is applied, jobs are withheld in a backlog from where they are released to meet certain performance targets. The decision that selects jobs for release is typically preceded by a sequencing decision. It was traditionally assumed that backlog sequencing is only responsible for releasing jobs on time, whereas more recent literature has argued that it can also support load balancing. Although th...

Evaluating the make-to-order performance of production control systems in a re-...

In the current Industry 4.0 era, simulation, along with approaches for dealing with production activity control, is considered of the utmost importance, for instance, in cyber-physical production systems, but also in any other traditional manufacturing environment. In this context, there are varying kinds of production activity control mechanisms that can be explored, and a wide range of contributions are alrea...

Designing and implementing interdisciplinary projects in a systems engineering ...

Interdisciplinary projects (IP) carried out by teams of students have been recognized as an important approach for learning in several fields and at several levels of education. In higher education, it can be an important drive for student learning motivation and an advantage for students when entering the working marketplace. The experience acquired while developing IP gives students technical and transversal ...

Comparative simulation study of production scheduling in the hybrid and the par...

Scheduling is one of the most important decisions in production control. An approach is proposed for supporting users to solve scheduling problems, by choosing the combination of physical manufacturing system configuration and the material handling system settings. The approach considers two alternative manufacturing scheduling configurations in a two stage product oriented manufacturing system, exploring the h...

A comparison of production control systems in a flexible flow shop

Production control in make-to-order must address the companies’ need for short delivery times and on-time deliveries. Several production control systems may be used to meet these needs. This paper presents a simulation study to evaluate the delivery performance of the TKS, GKS and POLCA production co ntrol systems, in the context of a make-to-order flexible flow shop. Since TKS is used for make-to-stock manufac...

Machado-Joseph disease: from pathogenic mechanisms to therapeutic strategies

Scheduling in product oriented manufacturing systems: Comparing hybrid flowshop...

Scheduling is one of the most important decisions in production control systems. This paper explores different approaches for scheduling two stage jobs in two configurations of product oriented manufacturing systems, namely an hybrid flow shop (HFS) and a parallel machine flow shop (PMFS). An industrial case is analyzed from the automotive components industry. The HFS problem resolution is compared with PMFS on...

Product documentation management through REST-based web service

Innovation is a creative process strongly associated with development and deployment of new products. This is essential in the global economy of today for the success and sustainability of companies. Collaboration between those involved in new product development (NPD) is an important requisite for product development and innovation. New product development involves not only the company and customers but also s...

Web-based decision support system for orders planning

Competition in the global economy is intensifying the implementation of the mass customization paradigm. This requires a substantial increase in the personalized interaction between client and producer. Agility in the order-production-delivery cycle optimization is a key element for industrial enterprises as a means to meet requirements of this paradigm. The use of agile methodologies for this purpose requires ...

A document-oriented web-based application for supporting collaborative product ...

Innovation is a creative process strongly associated with development and deployment of new products, i.e., goods and services. This is essential in the global economy of today for sustainability and success of companies. Good collaboration between those involved in new product development is an essential requisite for this success. Such collaboration, which involves not only company stakeholders but also suppl...
