This paper shows a novelty way to simulate the nonlinear behaviour of confined masonry walls subjected to in-plane lateral loading by using a 3D macro-modelling approach. For this purpose, the finite elements method implemented in ABAQUS software was used. All the 3D solid finite elements were modelled as a single part, which allowed avoiding modelling the contact interfaces between concrete and masonry elements. The nonlinear behaviour of the concrete and masonry were governed by two main types of failures: crushing and cracking, which were properly represented by the Concrete Damage Plasticity (CDP) model. Steel rebars were modelled as elastic–plastic with hardening and were assumed to have a perfect adhesion with the surrounding concrete by means of the embedded constraint. Prior to the modelling process, experiments were carried out whose results were used as patterns to validate t...

Studies present insufficient information on working models within the purchasing area using the BPM tool for agro-industrial companies, especially in Latin America, which aim to improve performance and optimize the processes of an organization. For this reason, the need for this research arises. This scientific article presents a model to improve supply management. The BPM methodology was proposed to standardize internal processes and the Kraljic matrix, a tool used in purchasing management to classify materials and optimize purchase planning. The level of compliance within the purchasing area did not satisfy the established policies, reaching only 55.96% and generating a gap in the savings goal of approximately S/.500,000. This causes an imbalance at the administrative and operational level due to a lack of general standardization of the processes. This triggered problems at the macro l...

Results of a research about the pathology and degradation on an earthen archaeological monument in the North Coast of Peru are presented, taking as case of study Huaca de la Luna, Moche Valley, as it is a macroregional diagnostic structure due to its geotopographical location, constructive techniques and the impact of meteorological, geophysical and chemical factors. This nationwide pioneering research developed several data obtaining techniques and methods of analysis, organized in relation to the nature of the impact factors and the 11 monitoring and registering stations established en the area of study. The study took as referents the North Facade (Sector A) and South Facade (Sector B) of Huaca de la Luna, to obtain and establish a contrasting line, between a protected sector (North Facade) and others exposed to the direct impact of abrasive winds (South Facade), to determine the diff...

Small and medium-sized companies seek to improve and innovate in all their different processes, since there is more competition, and they all seek to be leaders in the sector in which they operate. However, a problem that involves the entire distribution chain, as well as the profitability of the business, is the return of merchandise. The main objective of this research study was to propose an improvement proposal in distribution management to enhance the number of returns in a wholesale company for the traditional channel using the SMED, Lean Six Sigma and Demand Forecasting. The secondary objectives of this implementation were to analyze and understand the root causes of this problem to address it in the best possible way using diagnostic tools such as the Pareto Diagram and Value Stream Mapping. Likewise, to quantify and measure the impact of this indicator within the company through...
