“…However, some studies have deviated from the original steps that have been introduced by Sterman (2000). Bahadir and Akdag (2019) and Balachandra et al (2020) have done their studies by introducing the mapping part into the main steps. This has become a common practice in SD due to the importance of mapping.…”

“…The model testing was conducted as the fourth step of SD modeling. There are three types of testing in SD: direct structure tests, structure-oriented behavior tests and behavior reproduction tests (Bahadir and Akdag, 2019). Boundary adequacy test to check boundaries, structure assessment to see whether strict rules in the planning system have been applied and extreme condition test to see whether the model is accurate when extreme points are applied, are performed under direct structure tests.…”

PurposeThis paper examines how the altering nature of planning decisions affects operational efficiency in seaport container terminals. The uncertainty and the role of the planner were investigated considering the dynamic integrated planning function of the quay to yard interface.Design/methodology/approachA System Dynamics model has been built to illustrate the integrated dynamic environment. Data collection was conducted at a leading container terminal at a hub port. The model was simulated for different scenarios to derive findings.FindingsThe planner has been identified as the agent who makes alterations between the initial operational plan and the actual plan. The initial plan remains uncertain even when there is no impact from crane breakdowns, requiring a significant number of alterations to be made. The planner who had worked on the yard plan had altered (approximately 45%) the initial plan than the alterations done by the planner who had worked on the vessel plan. As a result, the feedback loop that is created by the remaining moves at each hourly operation influences the upcoming operation as much as crane breakdowns influence.Originality/value The uncertainty and the role of the planner were investigated considering the dynamic integrated planning function of the quay to yard interface. The findings of this study are significant since terminal efficiency is examined considering the quayside and landside as an integrated system.

“…Este artículo, tras centrar la simulación en el desarrollo de los servicios portuarios, ha concluido que la tecnología RFID (radio frequency identification) y la recopilación de datos del sistema de localización en tiempo real (RTLS) tienen un efecto positivo sobre la mejora de la productividad y el aumento de la utilización de los recursos. (Bahadir & Akdag, 2019) desarrollan un modelo basado en la dinámica de sistemas para las redes de contenedores hub & spoke. Su objetivo es comparar las políticas asociadas con algunos indicadores de rendimiento que incluyen la utilización de la capacidad, el nivel de servicio y, el rendimiento de inversión.…”

Este artículo se basa en la dinámica de sistemas aplicada al estudio del crecimiento del aeropuerto de Málaga. Para ello, basado en datos contrastables y en artículos científicos previos con objetivos similares, se plantea un modelo que contempla la sostenibilidad del aeropuerto de Málaga en términos de factores sociales, económicos y medioambientales, además de otros aspectos propios del aeropuerto. Se formula y valida un modelo de simulación mediante un diagrama de flujo simulado con el software Vensim®. De esta forma, se prevé información útil de la capacidad necesaria del aeropuerto en base al flujo de pasajeros y la congestión del mismo.

“…Research methods using human experts to calculate the quality of service for bus performance using long manual calculations will be time consuming and costly (Sam et al, 2018). Therefore, expert systems need to be developed because expert system are able to do better work than human experts (Bahadir & Hatice, 2019). When human experts are unavailable, expert systems are easily accessible.…”

“…By using this approach, this system could assist and navigate stakeholder, authority and operator in identified the of level of service for bus services especially in urban area (Norhisham et al, 2020). The system must be validated to ensure that it functions properly and that its credibility is maintained at an appropriate level (Bahadir & Hatice, 2019). The level of bus performance rating is based on consumers' opinion and feedbacks.…”

Every country in the world have faced a tremendous growth of development over the last decade. The number migrants from rural area to urban area has led to the increasing the traffic volume in urban and cities area. The public transport provided in Malaysia are public buses, taxis, train, Light Rail Transit and so on. Public transport has a very important role towards urban development and at the same time provides convenient transportation to passengers in economic terms. The objective of this study is to review suitable method to development of expert system view for quality of urban bus services in Peninsular Malaysia. The Expert System's knowledge base is the most significant component, as it is selecting rule from the knowledge base and then performs the actions of that rule. After that, the inference engine chooses another rule to execute. As for the framework of this research including task analysis, Data Collection, Development expert system, Refinement, Verification and Evaluation. The framework that on expert system development have been explained in this paper. There are five important attributes for evaluating bus services which are bus frequency, passenger load, Hours of service, on time performance and comparison of travel time of buses and private vehicles. These features were selected based on a as stakeholder questionnaires that conducted by previous research. According to TCQSM, these five attributes are also labelled in the five grades of service quality which are grade A to E. There is total 25 questions which is each attribute consists 5 questions each. A complete procedure on the fundamental understanding of the basic notions of the phases of Expert System creation with respect to its methodology and stages of development has been attempted.
