El capítulo tres, desarrollará la planificación del proyecto. En el capítulo cuatro, se desarrollará la implementación del modelo de planificación y control de la producción, además, se darán a conocer los resultados de la implementación. Finalmente, en el capítulo cinco, se detallarán las conclusiones y recomendaciones. / The present project was applied to a SME business in the textile sector, focused on the elaboration of men's trousers. The company decided to implement the production planning and control process due to the increase in costs due to penalties registered by the company and the lack of planning that obliged operators to work overtime to cover production stops. The implementation was done through the guidelines of the Project Management Institute (PMI), based on compliance with the points described in the Project Charter. The objective of developing these guidelines that the organization can meet the demand, considering the capacity of the company, the requirement of materials and planning of production. Five chapters are developed, which are defined as follows: Chapter one will describe the methodology implemented in the development of the project. In chapter two, the content of the act of constitution of the project is developed, which allows us to determine the scope, objectives, stakeholders, risks, etc., as well as the diagnosis of the company in the pre-implementation stage. Chapter three will develop the project planning, which will describe each of the nine steps that were considered for the development of the project. In chapter four, the implementation of the production planning and control model was developed, and the results of the implementation were made known. Finally, in chapter five, the conclusions and recommendations will be detailed. / Trabajo de suficiencia profesional

We are currently witnessing a rapid expansion of renewable power production, an increase dominated by wind and solar power. These intermittent energy sources, while having low production costs, increases the uncertainty on the electrical markets. Hydropower is a renewable source of electricity that is capable of controlled production. It is assumed that hydropower will take a more central role in terms of balancing deficiencies caused by intermittent sources. In this thesis, we present a detailed model of a single hydropower plant consisting of 𝑛 turbines. This model is then used as input of solving the optimisation problem of revenue maximisation for the hydro plant owner. The model used takes into account head effects as well as stochastic inflow of water and the stochastic fluctuations of electricity prices.

This article describes how Lean Manufacturing tools were applied in a Peruvian textile company. A production management model is proposed whose goal is to reduce the number of non-conforming products in the pants manufacturing line. For this, all information was gathered from the production area of the company under study. With the use of quality tools, the diagnosis of the current situation of the pants line was made, identifying the most significant defects, which were 19.43% of produced units in 2018. It was determined that the main causes of the observed defects refer to non-standardized sewing processes, quality control errors, non-standardized cutting processes, and poor production planning. The application of VSM and SMED allowed the correct standardization of denim pants production, TQM allowed proper control and quality management of the production process, and JIT for optimal production planning.

Los modelos de planeamiento y control de la producción han sido implementados con gran éxito en muchas empresas a nivel mundial, tanto en el ámbito manufacturero como el de los servicios. Actualmente, expertos e investigadores en el tema han encontrado manifestaciones que demuestran carencias en el desarrollo e implementación de este tipo de enfoques en grandes medianas empresas. Por esta razón, el presente artículo propone una metodología de mejora continua (PHVA) que incluye los modelos de planeamiento y control de producción con la finalidad de permitir un desarrollo sostenible y exitoso en el tiempo. La metodología está compuesta por 4 fases que son: a) planificar: en donde se proyecta todo lo que sucede y lo que se tiene que resolver, b) hacer: donde se ejecuta el plan de acción mediante herramientas ingenieriles, c) verificación: donde se valida si es factible el proyecto y, por último, d) actuar: donde se utilizan mecanismos de control. La metodología fue validada en una empresa dedicada a la fabricación de hornos industriales en el Perú, donde la ejecución generó la eliminación de ventas rechazadas por entrega fuera de tiempo en su primer trimestre después de aplicarlo y redujo también los problemas con calidad de insumo en 15% y planificación de compras en 9%. / The production planning and control models have been implemented with great success in many companies worldwide, both in manufacturing and services. Currently, experts and researchers in the field have found demonstrations that show shortcomings in the development and implementation of this type of approaches in large medium-sized enterprises. For this reason, this article proposes a methodology for continuous improvement (PDCA) which includes the models of production planning and control in order to allow for a successful and sustainable development at the time. The methodology is composed of 4 phases that are: a) planning: where everything that happens and what has to be resolved is projected, b) do: where the action plan is executed through engineering tools, c) verification: where it is validated if the project is feasible and finally, d) act: where control mechanisms are used. The methodology was validated in a company dedicated to the manufacture of industrial furnaces in Peru, where the execution generated the elimination of sales rejected by delivery out of time in its first quarter after applying it and reduced the problems with input quality in 15 % and purchase planning at 9%. / Trabajo de Suficiencia Profesional

The industrial development together with the globalization has led to that the markets are changing which in turn has led to an increased complexity of the organizational structures. Therefore, in order for firms to manage the customer’s expectations they need to develop their production planning. Although production planning and control is a mature area within research, there is a gap of knowledge regarding ways of planning the production operationally. Previous research within the area has mostly covered manufacturing issues through simulations and mathematical models, while the production planning and control structure has briefly been discussed on a more general level. This study addresses this through extending the knowledge on ways of planning the production operationally. Thus, the purpose of the research is to gain a deeper understanding for different ways of planning the production together with their implications. A case study was conducted at a Swedish high-tech make-to-order manufacturing firm characterized by low volume and high variety production, and the data was collected through interviews, observations and internal documents. This resulted in different ways of planning the production and their implications, which is divided into organizing planners and the planning process. The main empirical contributions of this research are summarized as: 1. Insight to current ways of planning through mapping the existing organization of planners and planning processes. 2. Implications with the different ways of working. 3. Understanding for what is suitable for the organization based on the implications, together with recommended actions on how to adapt. The study covers initial findings within the field, however, they should be seen as a foundation for future research as well as when taking decisions regarding areas covered within this research.
