A Model of Makespan Flow-Shop Scheduling Under Ergonomic Requirements

This paper address the recent growing interest the industrial environment has put over the healthy work. The ergonomics studies worker’s fatigue and muscular stress risks. It shows the need to measure and evaluate risks to improve the efficiency and reduce the costs. Based on a literature review from the scheduling and ergonomics point of view implications are highlighted. The paper presents a MILP mathematical model to minimize makespan in an n-job flow shop problem with sequence dependent setup times considering recovery times.

Implementación de actividades de aprendizaje y evaluación para el desarrollo de competencias genéricas: un caso práctico de aplicación de técnicas de Pensamiento de Diseño, y evaluación mediante rúbricas, de las competencias de Creatividad, Innovación y Emprendimiento.

La investigacion evidencia que existen practicas docentes que estimulan una mayor participacion de los estudiantes, dando lugar a un trabajo motivador que estimula el pensamiento creativo e innovador, que potencia su autonomia y facilite el aprendizaje de competencias transversales y profesionales. Durante los ultimos curso se han incorporado tecnicas de pensamiento de diseno, pensamiento visual y pensamiento ludico al proceso de ensenanza-aprendizaje de determinados contenidos de la asignatura Modelos de Negocio y Areas Funcionales de 4o curso de Grado en Ingenieria Informatica, con el objetivo de potenciar el pensamiento creativo e innovador de los estudiantes. En este trabajo se presenta dicha experiencia de innovacion educativa.

Order Promising Process for Supply Chains with Lack of Homogeneity in the Product

Traditionally, during the Order Promising Process (OPP), the homogeneity of different available units of the same finished good to be committed to customers has been assumed. However, this assumption is not valid for manufacturing contexts with Lack of Homogeneity in the Product (LHP). In this paper, special LHP-dimensions that affect the OPP are outlined. Based on them, specific LHP availability and allocation rules are defined.

Modeling the Master Plan for Supply Chains with Lack of Homogeneity in the Products

Master Planning of Supply Chains (SCs) with Lack of Homogeneity in the Products (LHP) strongly differs from other SCs. Although LHP affects SCs of different sectors, an absence of a common research body exists. In this paper, the characterization of LHP dimensions for Master Planning and their modeling is described. To validate the proposal an application to the fruit SC is presented.

Set-up Continuity in Tactical Planning of Semi-Continuous Industrial Processes

In most of production planning models developed in a hierarchical context at the tactical level setup changes are not explicitly considered. Its consideration includes decisions about the allocation and lot sizing of production, known as CLSLP problem. However the CLSLP problem does not account for set-up continuity, specially relevant in contexts with lengthy set-ups and where product families minimum run length are almost are similar to planning periods. In this work, a MILP model which accounts for this set-up continuity inclusion is modelled, solved and validated over a simplified real-case example.

Metodología para la reingeniería: basada en el modelado de procesos de negocio

Methodologies to improve processes help to find ways to improve industrial activity, reducing inefficiencies and improving the value perceived by the customer. One of the most widely used improvement methodologies to improve processes is the Business Process Reengineering. Yet, despite its high diffusion, many organizations complain about the low returns they have achieved with it and many experts stress its risks or criticize. Other methodologies surveyed are unwieldy and have problems such as long periods of implementation, or the high effort, knowledge and training required for use. Therefore, the objective of this paper is to propose a methodology for business process improvement simple and effective, by which is possible to identify areas of process improvement from its modeling. The result is an agile methodology, effective, that consists of seven stages by which it is possible to identify, both possible improvements in process, and improvements that are not technically feasible. All this with low training requirements and low cost. The main contributions of the proposed methodology are, therefore, its simplicity, ease of use and communication, its graphic aspect and its flexibility to adapt to different companies, sectors or types of processes.
