Road transport plays an essential role in freight transport throughout Europe, therefore, conditions that may hinder seamless operations in this sector require thorough consideration for ...evidence-based action. Critical amongst these key conditions is how, when, and where truck drivers stop, as a common set of rules strictly regulates their driving times and rest periods, which causes mandatory interruptions in the supply chains. However, approximating reliable estimations of freight traffic flows and road infrastructure usage constitutes a considerable challenge for researchers. This paper presents a robust data processing approach to designate rest area stops and to calculate the pertaining driving and rest times. Drawing on the abundance of navigation information provided by private fleet toll registration services, a comprehensive spatial-temporal truck stop database on all major rest areas along the toll road network in Hungary has been compiled. Based on the assessment and comparison of driving and rest times, driving and parking times have been analysed, including micro-scale analysis of particular rest areas. Both the methods applied and the results achieved can be of strategic interest to better understand truck driving patterns, as well as to develop targeted and cost-effective measures to streamline freight transport operations in other contexts.
Over 90% of seniors prefer to age in place, which is an idea supported by the European Semesters on Long-Term Care strategic plans for member states, but they do not have the necessary innovation to ...improve the living of the elderly in a properly built environment with sustainable financing. The spatial dispersion of housing and density in a functional area should be particularly taken into consideration by facilities’ managers and medical care institutions offering housing, healthcare and other services for the elderly in planning the built environment and other facilities for seniors because the costs of logistics (material transport, nurse workload, costs of other service providers, and transport of seniors in the case of daily programmes) greatly depend on it. Using data from a care centre in a Hungarian municipality, we simulated and optimised home healthcare routing and scheduling in various scenarios of spatial dispersion and changing density of clients. We modelled the rounds of caregivers visiting seniors in homecare as a multiple travelling salesman problem, and the solutions show the necessary workforce and service time requirements. The tool that enabled us to study the outputs of scenarios might help professionals forecast and plan for coming changes in the costs of nursing services caused by the growing number of seniors that may need help in maintaining their independence as long as possible, taking into account that the density and dispersion of households are also changing.
Več kot 90 % starostnikov bi se rado postaralo tam, kjer živijo. To idejo podpirajo tudi strateški načrti Evropskega semestra za dolgotrajno oskrbo (ang. European semesters on long-term care) za ...države članice, vendar ne vključujejo dovolj inovacij, da bi resnično izboljšali življenjske razmere starejših z ustrezno opremljenim okoljem in vzdržnim financiranjem. Prostorsko razpršenost bivališč in gostoto poselitve v funkcionalnem območju bi morala pri načrtovanju grajenega okolja in drugih objektov za starejše posebej upoštevati vodstva ustanov, ki starejšim zagotavljajo namestitev, zdravstveno oskrbo in druge storitve, saj so cene logistike (prevoz materiala, delovna sila, prevoz starostnikov v dnevne programe …) precej odvisne od teh dveh dejavnikov. Na podlagi podatkov doma za ostarele v eni od madžarskih občin smo ocenili in optimizirali načrtovanje poti ter razporejanje za potrebe oskrbe starostnikov na domu glede na različne možne prostorske razpršitve in z različno gostoto strank. Poti negovalnega osebja, ki oskrbuje starostnike, smo simulirali po modelu multiple travelling salesman problem, rešitve pa navajajo potrebno delovno silo in časovne zahteve za opravljanje storitev. Orodje, ki nam je omogočilo proučiti izide različnih možnosti, bi lahko tudi stroki pomagalo pri predvidevanju in načrtovanju prihodnjih sprememb pri stroških dolgotrajne oskrbe zaradi vse večjega števila starejših, ki bodo pri ohranjanju samostojnosti potrebovali pomoč, spreminjata pa se tudi gostota in razpršenost gospodinjstev.

The essential characteristics that distinguish homecare services from other routing and scheduling problems are relatively few patients being spread out over a large urban area, long transport times ...and several different services being provided. The approach that the authors present herein was developed to solve planning homecare services according to the criterion of increasing social sustainability and incorporating environmentally sustainable transport systems. The objective of this paper is to present a tool to plan the daily work carried out by a homecare service with assigned patients with specific care requirements. It relies on the resources of nurses with different qualifications by assuming costs that depend on both offering the service and the different chosen transport modes. The algorithm manages several priority rules by ensuring that homecare provider goals and standards are met. The developed algorithm was tested according to the weekly homecare schedule of a group of nurses in a medium-sized European city and was successfully used during validation to improve homecare planning decisions. The results, therefore, are not generalisable but its modular structure ensures its applicability to different cases. The algorithm provides a patient-centred visiting plan and improves transport allocation by offering nurses a better route assignment by considering the required variables and each nurse’s daily workload.

Due to the increasing number of requests for homecare services, care institutions struggle to perform in urban traffic, which eventually makes travel times longer and less predictable and, therefore, ...leads to a declining service quality. Homecare delivery scheduling and planning tools must lead to efficient reliable routes that allow the nursing crew to make the least efforts and use the fewest institutional resources, and that consider urban sustainability goals. For the case study, a European city was selected with 58,000 people of whom 73 patients received long-term care at homes provided by 11 homecare nurses. While maximising patient satisfaction, a homecare planning algorithm considered many means of transport and minimised travel times. The study reduced the total nurses’ working hours/day by a bus and walking combination, and by comparing if nurses ride e-bikes, which respectively reduced ~35–44% of the total time that nurses spent travelling. This result is applicable to an urban environment where the public transport network is sufficient and biking is allowed on a reasonable number of roads. Better homecare management can support the efficient use of resources of health care institutions, high-quality home care and aspirations towards livable communities and sustainable development.

The supply chain management challenges and inventory holding problems can easily be demonstrated by the widely known BeerGame simulation. In the Szabó-Szoba R&D Laboratory, we developed an ...android-based software application for tablets and smart phones for the purpose of having an adaptable, entertaining and effective program which can provide a real life experience to the participants about the nature of the bullwhip effect. Having an appropriate and comprehensive performance measurement system with the critical parameters and KPIs is inevitable for finding the right solutions - We used four perspectives of the Balanced Scorecard method. The innovative force of our research is based on the trainings: the discussion on outcomes and the team learning. The purpose of the current development is to build a new feature in the software: an artificial client can substitute one or more players in the supply chain, which makes decisions by using genetic algorithms.
