A bumpy ride: structural inequalities, quality standards, and institutional limitations affecting cycling infrastructure
(Elsevier Ltd, 2022) Tiznado-Aitken, Ignacio; Mora Vega, Rodrigo; Oyarzun, Gabriel; Vergara, Jaime; Vecchio, Giovanni; CEDEUS (Chile)
Structural socio-economic and institutional limitations can affect the implementation of cycling infrastructure. More stringent cycling infrastructure standards aiming to solve deficiencies might exacerbate disparities, especially in poor districts with fragmentary governance. Using an audit and quantitative and spatial analysis of cycleways, this paper examines to what extent structural inequalities and governance issues affect the availability and quality of cycling infrastructure, considering new indicative and normative standards aiming at improving cycling infrastructure in Santiago, Chile. Our results show that the distribution of cycleways is unequal and only partially complies with national quality standards. All districts in the city have both high and low standard bicycle lanes, but since district finances have huge differences, this can lead to inequalities in cycle coverage and districts' capabilities to address current standard problems. This raises relevant challenges regarding governance and how to ensure an equitable distribution of cycling infrastructure in Global South cities.

A comparative analysis of University Sustainable Travel Plans – Experience from Australia
(2023) Nelson J. D.; Balbontin Tahnuz, Camila; Hensher D. A.; Beck M.
Travel Demand Management (TDM) initiatives are widely applied by transport planners to establish and enable appropriate use of critical transport infrastructure. Less attention has been given to the specific case of TDM in an education precinct (university) context. Travel Plans have been promoted as a means for an organisation to encourage sustainable travel choices by their employees, visitors and customers. This paper offers an empirical contribution to the literature through a comparative qualitative evaluation of selected University Sustainable Travel Plans (USTPs) in Australia to identify the most important questions that a USTP should address explicitly. The evaluation comprised identification of a set of evaluation questions, completion of a template for each USTP considered and application of a simple scoring exercise. We also identify TDM measures that have been introduced as part of a USTP in response to the typical travel patterns exhibited in university settings. A contribution of this paper is to create a means of comparison of USTPs and to establish the components of a comprehensive travel plan.

A Data-Driven Approach to Discovering Process Choreography
(2024) Hernandez-Resendiz, Jaciel David; Tello-Leal, Edgar; Sepúlveda Fernández, Marcos
Implementing approaches based on process mining in inter-organizational collaboration environments presents challenges related to the granularity of event logs, the privacy and autonomy of business processes, and the alignment of event data generated in inter-organizational business process (IOBP) execution. Therefore, this paper proposes a complete and modular data-driven approach that implements natural language processing techniques, text similarity, and process mining techniques (discovery and conformance checking) through a set of methods and formal rules that enable analysis of the data contained in the event logs and the intra-organizational process models of the participants in the collaboration, to identify patterns that allow the discovery of the process choreography. The approach enables merging the event logs of the inter-organizational collaboration participants from the identified message interactions, enabling the automatic construction of an IOBP model. The proposed approach was evaluated using four real-life and two artificial event logs. In discovering the choreography process, average values of 0.86, 0.89, and 0.86 were obtained for relationship precision, relation recall, and relationship F-score metrics. In evaluating the quality of the built IOBP models, values of 0.95 and 1.00 were achieved for the precision and recall metrics, respectively. The performance obtained in the different scenarios is encouraging, demonstrating the ability of the approach to discover the process choreography and the construction of business process models in inter-organizational environments.

A decision support system for planning and scheduling bottling lines in a large winery
(2017) Cawley A.M.; Maturana Valderrama Sergio; Pascual R.
Planning and scheduling bottling lines in large wineries is an important process that greatly impacts production costs of large wineries, which have several of these lines, and the service level it provides to its clients. A ''good" plan needs to ensure that the wine is packaged and available on time to serve the demand, or else it can affect the service level given to the customer; it also should keep inventory low and efficiently use the bottling lines and labor. The many different aspects that have to be considered, such as the sequence of the products to be bottled, the constraints that have to be met due to production, sanitation, and labor requirements, the different types of setups, some of which are sequence dependent, and the large number of products that have to be scheduled on the different bottling lines, make it a very hard problem to solve without the help of a decision support system (DSS). We describe in this paper a DSS that was implemented for a large winery in the US that uses a mathematical model to help find a good plan that both minimizes production costs and maximizes the service level of their clients. The results obtained on test problems showed that the system could obtain cost reductions in the order of 15% to 30%. A visualization and intervention software was built into the system to support the planning process by allowing the planner an easy visualization of the production schedule through Gantt charts and also the possibility to intervene the solution using drag and drop. Key performance indicators are also presented to help analyze the solution from a cost, production parameter, demand, and capacity perspective. The system is able to provide good solutions in a reasonable amount of time, running on a standard personal computer.

A discrete-event public transportation simulation model to evaluate travel demand management impacts on waiting times and crowding conditions
(Elsevier B.V., 2023) Soza-Parra, J.; Tiznado-Aitken, Ignacio; Muñoz Abogabir, Juan Carlos; CEDEUS (Chile)
Several approaches have been proposed and adopted by researchers and decision-makers to improve and deal with public transport operation issues, especially travel demand management (TDM) measures. Disruptions like lockdowns provoked by weather conditions, political riots, special events, natural disaster issues, or the recent COVID-19 pandemic create a need for tools to manage public transport demand and supply o keep users circulating in an efficient, convenient and safe manner. Our work develops a simulation tool of the operations of a public transport system using smart card, GTFS and census data to evaluate the impacts of different intervention scenarios using the pandemic context as a case study. Using a pre-pandemic baseline scenario, we study the impact of several travel demand and public transport supply measures, focusing the analysis on waiting times and crowding conditions inside vehicles and platforms. As a result, we generate easy-to-analyze visual outputs that facilitate prioritizing actions at the metropolitan and district level, identifying where and when waiting times and crowding conditions would exceed certain thresholds.
