The handling of external operational loss data by individual banks is one of the longstanding problems in risk management theory and practice. The extant literature has not provided a method to identify the best way to combine internal and external operational loss data to calculate operational risk capital. Hence, to improve the knowledge and understanding of internal-external data combination in operational risk management, this study applied a simulation-based evaluation of well-known data combination techniques such as the scaling, the Bayesian, and the covariate-base techniques. This research considered operational losses arising from internal fraud in retail banking within a group of international banks that share data through an operational loss data exchange. One of the key elements of the simulation-based statistical evaluation was the development of a dynamic internal fraud mod...

Data envelopment analysis is a non-parametric practical method to compute efficiency on decision making units. The present work applies DEA on then branch network of one of the most important peruvian banks with a Lingo optimization model and a Microsoft Excel spreadsheet. The problem is solved under two approaches (financial/management and selling) in order to compute both global and technical efficiency of each individual branch. Additionally, a ranking system (based on average efficiency, time-windows analysis and benchmark-solution recurrence) is proposed as a management tool for the direction teams.

Currently, one of the worrying problems in vehicular traffic is the large number of cars making left turns at intersections. This phenomenon has generated various challenges in terms of road safety, traffic fluidity and transportation efficiency. To face this situation, today, alternative and innovative solutions are being proposed through the design of unconventional intersections. One of these is the displaced left turn (DLT) intersection. However, given that intersections of this type are few in Peru, it is necessary to evaluate the operational performance of this type of intersections. Therefore, this study evaluates the operability of DLTs using a scenario comparison study based on selected performance measures. For this, the case of a conventional intersection in the city of Lima is evaluated, in which the DLT was implemented in two accesses that have a greater flow of vehicles. Th...

In this article, we prove the existence and uniqueness of the solution of the homogeneous generalized Schrödinger equation of order m in the periodic distributional space P0, where m is an even number not a multiple of four. Furthermore, we prove that the solution depends continuously respect to the initial data in P0. Introducing a family of weakly continuous operators, we prove that this family is a group in P0. Then, with this family of operators, we get a fine version of the existence and dependency continuous theorem obtained. Finally, we give the conclusions and remarks derived from this study.

The research problem arose from the need to implement a system to remotely manage the traffic operations of the network of traffic lights to reduce vehicular congestion. The procedure involved designing the placement of electronic sensors to track the number of vehicles in the area. This allowed for the testing of different operational strategies for modifying the timing of the traffic light signals. A simulation model was used to test these strategies in seven intersections on Av. Petit Thouars in Lima, between Av. Alejandro Tirado and Av. 28 de Julio. Detectors were installed at the access points of secondary access streets to the main road (Av. Petit Thouars) which yielded cumulative positive results. Alternatives 1 and 2 produced a 59% reduction in queues, thus demonstrating the validity of the general hypothesis.

Radioisotope techniques are highly useful tools to investigate variety of problems in oil & gas refining and petrochemical industry. Major techniques and applications are in routine service to industry of many countries. Gamma-ray scanning, often referred to as “column scanning”, is a convenient, cost effective, fast, efficient and non-intrusive technique to examine inner details of a process column or a reaction vessel, while it is in operation. Column scanning allows an engineer in petroleum refineries, gas processing installations and chemical plants, to study tray or packing hydraulics inside a distillation column at any set of on-line condition. It provides essential data to optimize the performance of columns, extend column run times, trackthe performance-deteriorating effects of fouling and solids deposition, and identify maintenance requirements well in advance of schedul...

The Business Alliance for Secure Commerce (BASC) management system is a strategy to strengthen the security and efficiency of companies in the logistics sector by preventing illegal activities such as smuggling and drug trafficking. The problem lies in the need to evaluate its impact on operational efficiency and security. Prior to its implementation, the company had deficiencies in traceability, regulatory compliance and security, and employees did not have a clear understanding of the impact of this system on these aspects. To assess this impact, a mixed methodology was used, combining a document review and a questionnaire structured in five key sections: general data, perception of safety, operational efficiency, regulatory compliance, and challenges and benefits of the system. The results indicate improvements in performance indicators: on-time deliveries increased from 88 % to 96 %,...
