Resumen
A large number of studies have demonstrated the strong influence of and correlation between innovation and export activities as key factors of the firm’s competitiveness. However, these two activities have usually been considered independently of each other in terms of management and support. This paper relies on the characterization of a conceptual innovation/export common space representing the synergistic effects between these two activities. A hybrid AHP/Flowsort MCDM-methodology is proposed in order to model this common space through the evaluation of a framework of joint practices related simultaneously to the innovation and export capabilities of SMEs. The relevance of this methodology is tested through the design of a decision-making tool applied to a French exporting and innovative SME. This case study opens up further research perspectives and points to areas for improvement in the evaluation of SMEs’ capabilities.

Resumen
The agile transition is crucial for traditional organizations to remain competitive in the current market, which is characterized by a fast-pace and a constant need for innovation. In order to implement this transition, organizations must adjust their mindset to the new agile values. Despite its evident benefits, the transition to agile model is complex and time-consuming, posing many challenges to organizations. Since the agile philosophy is people-centered, rather than process-centered, most challenges are related to the human aspects of this transition and they demand a large transformation in all areas of the organization. This article provides a Systematic Literature Review (SLR) of the human aspects of agile transition and summarizes the existing literature into three categories: People, Management and Organization. Its main objective is to assist organizations undergoing agile transition in reducing risks related to this process, by acquiring knowledge on the challenges involved and implementing the proposed recommendations.

Resumen
In this context, we introduce a multi-objective optimization problem (MOOP) to simultaneously minimize the objectives of cancerous cells density as well as the approved drug amount in order to optimize the medical remedy of a tumor. The main aim is gaining a proper pattern for medical supervision to sick people with malignant cancer. To this end, a comparison is made between the two important and useful methods of non-dominated sorting genetic algorithm II (NSGA-II) and multi-objective particle swarm optimization (MOPSO). The gained Pareto's Curve here yields a series of optimal protocols. A desired optimal technique is then selected from these optimal protocols for drug supervision, relating to an under consideration criterion. The results show that in both criterions the convergence and expansion of Pareto optimal fronts of the performance of the NSGA-II method is better compared to MOPSO.

Resumen
In this paper we tackle a two-dimensional cutting problem to optimize the use of raw material in a furniture company. Since the material used to produce pieces of furniture comes from a natural source, the plywood sheets may present defects that affect the total plywood that can be used in a single sheet. The heuristic presented in this research deals with these defects and present the best way to handle them. It also considers the use of the plywood sheets for the long term planning of the company, since usually purchases of raw material are done only at certain periods of time, and must last for several weeks.
Experimental results show how an intelligent cutting plan and selection of the plywood sheets reduce considerable the amount of raw material needed compared with the current operation of the company, and guarantees that the purchased sheets last during the planning period, regardless of the available area to cut pieces on each plywood.

Resumen
The scheduling of examination timetables is a problem that arises in educational institutions such as universities, high schools and junior high schools. Mathematical programming models are used to solve this administrative problem. This is known as an NP-complete problem from the perspective of computational complexity, because of the large number of possible timetable combinations. This article presents a new strategy for defining the scheduling of examinations by stages, by decomposing the original problem, using binary variables, into three mathematical models. The assignment considers students, time slots, classrooms and examiners. We have taken the Department of Postgraduate Studies of the Tecnológico Nacional de México in Celaya as a case study. The strategy generated a significant reduction in the number of binary variables, Making it possible for the exact technique of branch and bound to reach efficient times in the search for an optimum solution at each stage.

Resumen
Advanced engineering is essential for the evolution of today´s society. The possibility of mixing several disciplines allows academics and industries to align and survive to the fourth industrial revolution. The mix of signal processing and production processes disciplines was detected by Universidad Autonoma de Ciudad Juarez (UACJ) to create the Ph.D. program of advanced engineering science. Therefore, in this paper, an overview of the latest works in both disciplines applied to advanced engineering are discussed. First, we discuss the reasons of what advanced engineering implies, followed by a justification to mix signal processing and production processes. Then, original research works in computer vision, digital image processing, augmented reality and pattern recognition are discussed. After that, the discipline of the production process is addressed by discussing works in lean manufacturing, ergonomics and human factors, and supply chain. At the end, the future of the proposed mixture is discussed.

Resumen
At the present time, business and industrial organizations are given the task of good planning when determining any type of acquisition for their services. That is, identify and evaluate the different options of provision of inventory that allow the company to maintain and improve its offer. Within this evaluation, it can be noticed that the decision of the management and administration of resources, involves the problem of distribution (goods and services), being also of great importance within the supply chain. In this way, in this paper we analyze the Capacitated Vehicle Routing Problem with ellipsoidal distances, which includes an inventory model with uniformly distributed demands, so that inventory costs and distances are minimized. With this contribution, the way to minimize total costs in a distribution period can be refined. For validation, computational evaluations obtained from the mathematical model and backed by the software are presented (LINGO 18.0 - MATLAB).

Resumen
Wind energy is one of the most promising renewable energies in the coming years. The construction of wind farms is destined to increase in the U.S. and Mexico, only Mexico has a wind potential of 19,805 GWh. An important stage in the construction and design of wind farms is to solve the Wind Farm Layout Optimization Problem (WFLOP). The design of the wind farm involves many factors. One of the non-linear factors is the wake effect, which reduces the energy produced by wind turbines. To maximize the wind energy capture, in this paper an evolutionary algorithm is implemented in such a way that the placement of wind turbines within wind farm be optimized taking account the individual energy loss due to wake effects. The evolutionary algorithm is implemented in several instances. The results obtained by the evolutionary algorithm are compared with the results of the Generalized Reduced Gradient (GRG) algorithm.

Resumen
Abstract. This paper proposes a risk study to suffer from obesity based on genetics and caloric intake. Using the calculation of the amount of glucose ingested and Hopfield networks to detect patterns of kinship between a control group and their relatives with obesity or bad eating habits. Of the volunteers who are at risk of triggering obesity, 43% have good nutrition and obese parents, another 43% have a poor diet with obese parents, those volunteers who have poor nutrition and do not have overweight parents, have a 10% risk of obesity, those who do not have obese parents and have poor nutrition, their risk percentage is 4%. It was possible to detect the predominance of genetics in obesity and the advantages of the use of computer techniques in the support for the timely detection of obesity.
