Robust parameter design (RPD) involves the effects size, component restrictions, and fixed effects of mixture-process-noise variables (MPNV) in product and process design. The traditional methodology does not necessarily ensure a minimum variance and a reasonable model adjustment. Contrary to process and noise variables, mixture factor levels are not independent, negative proportions are not allowed, and their summary must be equal to unity. A transformation function enables the incorporation of noise factors into the response surface model, thus estimating the mixture-process optimum variables that minimize the variance expression without a cross array. In addition, it allows the determination of a confidence region over a point to achieve another component combination with similar or higher quality products. The third-generation process capability index, Cpkm as an alternative signal to noise ratio (SNR) estimator, improve process capability and product quality for fixed factor problems for full factorial and fractional experiment designs with or without repeated measures. Keywords: Robust Parameter Design, Dual Response, Process Capability, Mixture Experiments, Signal-To-Noise Ratio, Response Surface Methodology.

Demand forecasting is a very important feature in companies since it provides valuable information for taking decisions about planning, pricing and business growth strategies. In this paper, multi-country demand forecasting for a company of the construction industry is carried out. In the case study, we analyze different external variables from open data sources of each country in order to reduce uncertainty in demand forecasting. The analysis is carried out with different univariate and multivariate methods. The results show how the consideration of external variables improves the forecasts. Finally, forecasts of different kinds of demand are evaluated using Syntetos, Boylan and Croston classification methodology. Key words: Demand forecasting, forecast models, multivariate methods, accuracy indicators

Presently, achieving the circularity of supply chains is a major challenge. The difficulty consists of the assimilation by the actors in the supply chain and its own complexity. Therefore, this research focuses on the main differences among the three main variables (integration, circular economy, and the elements of the traditional supply chains) of a supply chain in the coconut sector in the province of Manabí, Ecuador. To achieve this, two hypotheses and their possible combinations are defined. The first hypothesis focuses into the existence of the differences among variables. The second one, is based on the possibility of a positive strong correlation among the variables. Hence, relationships between the three variables in the context of circularity are identified. The supply chain under study is formed by 160 actors, limited to the national sector. For the diagnosis of each of the variables, three check lists are used, which allow to compute a general value for each variable in each actor and in the supply chain. Results indicate that: (a) the supply chain of the coconut sector in the province of Manabí has a performance evaluated to be fair in terms of integration levels, circular economy and the definition of the supply chain; (b) actors dedicated to production and manufacturing show slightly superior performance compared to those dedicated to selling to the customer; (c) the actors maintain proportional and direct performances in the three variables. As a consequence of this study, strengths and opportunity areas of the coconut sector to accomplish an effective transition towards the circularity. Key Words: supply chain management, circular economy, coconut sector case study

In most scientific articles where a state of the art is presented, a bibliometric analysis is not included. Considering that a state of the art aims to present what has been researched in a research field, it is very useful to accompany this study with additional information regarding the main journals where these works are published, as well as who are the main scientists or institutions researching on the topic in question. In the first stage, this research work presents a state of the art describing the most relevant research articles on technologies applied to occupational Ergonomics. In the second stage, a bibliometric analysis is carried out to gather relevant information on the main technologies being applied in occupational Ergonomics, together with the characterization of the main agents involved in this field of research. With regard to the results obtained, it is worth highlighting that the United States is the country where most research is carried out, followed by European countries such as the United Kingdom, Italy, France and Germany. On the other hand, Virtual Reality, digital technology and robotics are some of the technologies with a preponderant role in this area. Keywords: Ergonomics, Virtual Reality, wearable technology, eye Tracking, collaborative robot, exoskeleton

The companies avoid going to the bankruptcy process, they do it late and a great majority finish with liquidation; probably because the bankruptcy process does not meet the objective of restructuring companies with financial problems. If the active resources and the granted credit were in balance (standard accounting principle); this problem would disappear; but it certainly is not the case and the problem persists. Thus, our work aims to determine the degree of impairment shown by the assets in bankruptcy proceedings to try to reveal the variables that could explain the greater or lesser impairment. This work highlights the lack of efficiency of the bankruptcy process due to the poor credit satisfaction of its creditors in liquidation. This helps to establish a cause, specifically, the low liquidation value of the assets. This implies that the culture in the bankruptcy process must change one should go to the process as soon as possible and try to balance assets and equity and payable at all times. Keywords: bankruptcy proceeding, liquidation value, efficiency, risk, illiquidity.

Emerging technologies associated with Industry 4.0 require such dynamic management methods that solutions based on conventional methods are sometimes not acceptable. Under this premise and with the help of process reengineering, it was determined of interest to carry out a study applying a novel tool to projects in the industrial design environment, obtaining exceptional results. Said tool was the agile Scrum methodology, a priori exclusively used for ICT environments, characterized by the incorporation of the client into the process, flexible planning, teamwork, acceptance of failure and the diffuse profile of the objective in its early stages. stages. These characteristics make it possible to respond to the requirements of industrial creativity such as the need to fail quickly, cheaply and frequently. Developing a new mixed work model arises from the verification of the existence of incompatibilities between predictive and agile methodologies, a model of which its viability has been verified through three years of empirical study. The answer sought has not been to facilitate WHAT update a product requires but HOW the next update should be carried out, favoring the work of industrial design managers to obtain both the success of the project object and the success of the project. For practical development, we have worked in a university environment linked to business projects, with the participation of 150 students and engineers, obtaining 14 prizes in national and international design competitions. The results of the empirical study demonstrate the viability of optimizing industrial innovation through a combination of double gates governed simultaneously by the project manager and the project object manager (product owner). Keywords: Innovation, Industry 4.0, Project management, Agile methodologies, Industrial design.

Crowdimpacting is a form of participatory financing in projects that generate a positive social or environmental impact, in addition to an economic benefit. This initiative arises in Spain, as a very attractive and beneficial financing model for society. However, it faces a series of barriers that can limit its expansion. This reflexion article analyzes the current situation of crowdimpacting, identifies the barriers faced, and proposes a solution to overcome two of these barriers: the creation of an online crowdimpacting community. This community will allow a greater diffusion of impact projects among potentially interested investors, as well as the link between the entity proposing the project and the investors will not disappear once the necessary funds for the development of the project have been collected. The methodology used combines the critical analysis of the existing literature on crowdfunding and crowdimpacting, as well as the inductive method. The main conclusions of the work carried out are that (1) the crowdimpacting is a new investment formula that offers a viable alternative to traditional financing methods, while allowing small investors to participate in the development of socially and environmentally responsible projects; and (2) the creation of an online community can help to overcome some of the barriers to crowdimpacting supporting its dissemination and consolidation.

The purpose of the study was to classify the excellence management models and awards, according to the types of organizations, the criteria for their application, and the countries in which those models and awards were applied. Some conclusions were that the awards for excellence in management that have been delivered in the five continents were based exclusively on the three main models: EFQM, Deming’s Model of Excellence, and Malcom Baldrige, which were created with the aim of continuous improvement according to diverse criteria and principles, and these models used different percentages of them and that these excellence models have been used together with a combination of criteria in a single context to make the implementation feasible. It is recommended to extend an investigation in detail due to that the classifications can be given not only in the principles that are used for obtaining an excellence award or in the countries that the models are used, but also with the information about the industries in which were used and considering the moment in which the application has been submitted. Keywords: Quality Management, Excellence Models, Excellence Awards, Excellence Management Models, Excellence Management Awards

In recent years, the logistics sector has witnessed the entry of different actors with new business models. Among these actors, there are mainly startups that, with technology-based solutions, are introducing great innovations in logistics. In this sense, this work focuses on the analysis and understanding of new business models based on innovation that are emerging and transforming the logistics sector by categorizing them through large groups. The categorization is made based on the review of the literature and the analysis of real cases of startups. Thus, five types of business model based on innovation and different specific areas of application are presented in each of them, which are illustrated by describing microcases of logistics startups. The results allow to identify different opportunities to create value by applying innovation and the main challenges faced by companies in the sector, as well as to identify the adoption of new technologies such as Internet of Things, Big Data and Cloud Computing, whose use is currently a growing trend in logistics.
