Optimisation decision support software for
resource scheduling and management

For more than 30 years, SISCOG has been combining generic and client-specific knowledge, incorporating experience, research & innovation and mobility industry trends, to design optimisation resource scheduling and management software solutions for the transportation cluster.

The SISCOG Suite includes a combination of Artificial Intelligence and Operations Research techniques, and offers management, schedulers, and dispatchers, software tools to improve business productivity and quality and, ultimately, the satisfaction of employees and passengers/clients.

The Team



38 Successful years

In the 1980s, João Pavão Martins and Ernesto Morgado, both Fulbright Scholars holding PhDs in Artificial Intelligence from State University of New York at Buffalo (USA), decided to combine scientific knowledge, cutting-edge technology and practical know-how and apply it to the rail business. Together, they created a key player in the rail and metro operations software market. Today, SISCOG ranks high in the world for rail scheduling systems and keeps expanding to new markets.

Business Ethics

Information technology, artificial intelligence and operations research share a common aspect - a highly competitive and innovative spirit under constant change. SISCOG follows these natural transformations keeping a continuous commitment to making decisions based on an ethical and righteous conduct.

We honour our Code of Ethics and Conduct, which determines our relationship with employees, clients, suppliers, partners, society and environment.

Conciliation between Professional, Family and Personal life

Balance between the three dimensions increases well-being and satisfaction

From the employees’ perspective, this balance is fundamental to increase levels of well-being, quality of life, personal satisfaction and personal and professional development. From SISCOG's perspective, this conciliation eases the contribution and involvement of employees with the organisation and its objectives, the achievement of higher productivity, and offers the benefits that arise from promoting their personal development and consequent learning.

The company joined the Pact for Conciliation in 2019, the first measure taken by the Portuguese Government that committed a pioneer group of companies and public bodies to the implementation of related practices.

SISCOG annually defines a plan within the scope of this conciliation, with objectives, actions, responsibilities, and deadlines. This plan is aligned with the contributions received from stakeholders and the organisation's strategy, and includes actions related to improving training offerings, increasing the organisation's attractiveness, and employee satisfaction and well-being. The Work-life Balance Policy can be found here.

SISCOG maintains an Integrated Management System that includes the principles of the Conciliation between Professional, Family and Personal life standards from NP 4552.

Suggestions, needs, or expectations regarding the professional, family and personal life balance can be sent by any SISCOG stakeholder to conciliation@siscog.pt.

Quality and Innovation are at the heart of everything we do

These are key to SISCOG´s successful products and systems, and are powered by devoted teams, by abiding industry standards, monitoring international trends and advancements in the state-of-the-art, and listening to clients' suggestions and needs.

SISCOG has been investing on research, development and innovation (RD&I) from inception, and since 2003 dedicated an entire department to RD&I. In this lab, a team of highly-skilled researchers, develop and improve optimisation models used to solve resource scheduling challenges faced by transportation companies. The work is done internally but also in partnership with other research labs, universities and even clients.

This positioning is consistently recognised through published papers, awards and our clients’ continuous use of the systems.

SISCOG maintains an Integrated Management System that includes the principles of the Quality and the Research, Development and Innovation management standards (ISO 9001 and NP EN 4457, respectively).



Information Security

Security of information as a standard since inception

As one of the most critical assets for the operation and survival of an organization, information’s security management requires the selection and implementation of the best security controls, offering a high degree of trust to all stakeholders.

Our software development and maintenance undergo strict security of information management in terms of confidentiality, availability and integrity.

SISCOG maintains an Integrated Management System that includes the principles of the Information Security management standards from ISO 27001.




Environment respect is key to a sustainable and socially responsible organisation

The SISCOG Suite, as a set of products that optimise the operations of transportation companies, contributes for the sustainable use of resources by our clients, namely by enabling an efficient use of rolling stock, hence directly reducing power consumption.

At SISCOG, water and power consumption, and waste separation and reuse, have always been safeguarded. As has the concern in reducing our travel footprint by privileging meetings through the use of modern high quality communication technologies. These aspects reflect SISCOG’s major impacts on the environment, and efforts and goals are set out to continuously minimise them.

Our environment responsibility goes an extra mile, by maintaining an Integrated Management System that includes the principles of the Environment management standards from ISO 14001.
