Assessing knowledge level of stakeholders on transport interchange design and operation

The paper advances the results of the on-going work conducted within the frame of the European Twinning project ALLIANCE. In the effort to assess educational needs of different stakeholder groups involved in the domain, this paper’s main interest is to study knowledge and importance of governance issues and smart solutions, which enable smooth and seamless interconnectivity of alternative transportation modes, and techniques for facilitating decision-making and evaluation of these solutions. Data were collected through a questionnaire web-based survey addressed to different stakeholder groups in Latvia: policy makers, industry, academia/research and students. From the statistical analysis conducted it was concluded that there are differences in the average rating of different thematic areas (i.e. governance, smart solutions, decision-making) by the respondents. Especially stakeholders belonging to policy makers, industry and students valuated their knowledge on Governance and Smart Solutions below average and at the same time these areas as important for carrier development. Recommendations on the adaptation of an education/training program for Latvia were drawn from the above analysis

Making Warehouse Logistics Smart by Effective Placement Strategy Based on Genetic Algorithms

Supply chain executives are faced with the challenge of reducing labor costs. Travel time or picking efficiency can easily account for 50% or more of order picking time. If we omit human factor and the technical equipment of the warehouses, picking efficiency is mostly affected by two factors: correct combining orders into a single travel instance and picking orders in batch is the first factor; the second one is a goods placement – the more effective the goods are located, the shorter will be the picking distance for each order or batch of orders. It means that individual orders will be picked faster. Usually to determine the correct location for the goods 3PL’s are using ABC analysis that includes indicators like count of orders, goods turnover, picking rate, weight etc

Strategy for Research Development in the University. Case Study of Transport and Telecommunication Institute

The paper represents Transport and Telecommunication Institute research programme for period of time 2016-2020. Developed research programme should insure sustainable development of TTI as research institution and should raise research capabilities of the organization by planning and further implementation of the collaboration activities with national and international partners. The analyses of main technology development in the area of TTI research activities, framework for development of research programme, the structure of key TTI strategies and main directions of TTI research activities are described in the paper sides

Simulation as a decision support tool for airport planning: Riga International Airport case study

This research considers the aspects of decision-making according to the airport activities. The decision about airport planning and management should be comprehensive and operative and of course, the assessment of alternative decisions is necessary. The purpose of this research is to highlight the role of simulation modelling at the stage of airport development. The authors present the methodology of a model-driven decision-making approach and then describe 2 cases of using simulation for Riga International Airport (RIX) development. The 1st case study is used for analysis possibility of the development of the airport’s surrounding territory. The planned massive development of RIX and the surrounding area requires detailed analysis for increasing its positive impact on regional and national business economics, social aspects, business and the environment. The 2nd case supports decision-making for the needs of the terminal reconstruction, presents a helpful tool for visualization of the tendencies in the future, and allows the analysis of the different infrastructure layouts. Both cases give the possibility to predict the situation and evaluate the service provided for passengers (travellers) of the airport. Simulation modelling allows to study complex system – airport and evaluate direct and indirect impacts of planned reconstruction. First published online 20 January 202

Evaluation of Freight Measures by Integrating Simulation Tools: The Case of Volos Port, Greece

Simulation modelling tools have been widely adopted for the evaluation of alternatives in transport planning, management and logistics. The complexity that underlies in transport systems and logistics necessitate the integration of different models that are capable of overcoming limitations that may exist individually to each model. Towards this direction, this paper aims to integrate two simulation software and use the integrated model for the evaluation of traffic and logistics measures in the wider area of Volos Port, Greece. The built model is able to simulate the traffic conditions on a transport network along with port’s intra-logistics processes and is used to evaluate a set of measures in the year 2030, by comparing it with the situation in the year 2030 without having implemented any new measure. For the evaluation, a set of indicators is used to gauge the environmental and transport impacts. The analysis is completed by using a multi-criteria decision making tool to generate the Logistics Sustainability Index (LSI) to summarize the information that is provided by the indicators. The results show that the use of integrated simulation models can provide a holistic impact evaluation of complex decisions with a high level of accuracy
