Janáček","doi":"10.1109/SOLI.2017.8120969","DOIUrl":"https://doi.org/10.1109/SOLI.2017.8120969","url":null,"abstract":"Crew scheduling is an important optimization problem in the railway industry. In last decades, the extension of computational resources made it feasible to address real-life problems generating large-scale set covering problems. Broadly used is the concept of shift frames, which is well suited current practice of several railway operators. In the case when the problem is described by one complete model, which covers all characteristics of the crew scheduling problem, it may lead to a large linear programming problem formulation, which can attack the limits of a common IP-solver. To overcome this obstacle, column generation technique can be used. Column generation technique can reduce the size of solved model. Despite the fact that it cannot find the optimal solution, it can enable to solve larger instances. In this contribution we explain the concept of frames used in design of periodic timetable and analyze the property of the particular frame networks. We explain the column generating principle in connection with the crew scheduling problem. We present improving methods to accelerate the column generation method that are able to find solution of the solved sub-problem faster and different strategies of producing the initial collections of columns, which enable to make the column generation process more effective. Although the computational time in the scheduling problems is not an critical issue, the reduce of the computational time can enable to use this method in the decision supporting tool for the crew schedule design under practical conditions, especially in large scale problems. To test proposed improvements we use various benchmarks of real problems from crew scheduling in railway transportation systems.","PeriodicalId":190544,"journal":{"name":"2017 IEEE International Conference on Service Operations and Logistics, and Informatics (SOLI)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122008057","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our distributed system avoids a single point of failure, is scalable, fault tolerant and robust. We describe an agent-based distributed system to conduct a set of procurement auctions. The vehicles are the “sellers” and the passengers are the “buyers” in the auction. Each vehicle bids for the passengers with a bid value which is an inverse function of the time it would take the vehicle to reach the passenger. In our agent based architecture, the various software agents reside on different systems and we describe distributed algorithms for their communication. We have performed simulations of a vehicle fleet in two different locations (Bangalore, India and Tyson's Corner, Virginia, USA) and compare the maximum and average waiting times of the passenger of our algorithm with a FIFO algorithm. We also compute the ratio of the time in which the vehicle is servicing a passenger to the total time to compute the fuel wastage. The results show that our system improves the maximum and average waiting times of the passengers, as well as the fuel costs for the vehicle fleet. Furthermore, we show that such a distributed system reduces the time it would take on average to respond to customer requests, as compared to a system which is not distributed.","PeriodicalId":190544,"journal":{"name":"2017 IEEE International Conference on Service Operations and Logistics, and Informatics (SOLI)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133372948","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To deal with this problem, we designed a FAQ creation system with a strong focus on the effectiveness of its data-curation component. We conducted a field study by inspecting two sources: incident reports and a QA forum. The first source of incident reports showed a high F-score of 89.9% (precision: 82.5%, recall: 100%).

The retailing industry is moving to a new phase, in which the distinctions between traditional and online channels disappear, namely omni-channel (OC) retailing. The new challenge is to understand how multiple channels can be synergistically managed to provide a seamless customer experience. In OC retailing, logistics represents a key success factor due to its impact on both customer service and total costs. Retailers need to define the distribution configuration for serving the online demand, making decisions on the integration level between online and traditional channels. Companies can set an ad hoc network for the online channel, or use the same network for both online and traditional channels at warehouse and/or transport levels. In this paper, we developed an assessment model of the operational costs for three distribution configurations in OC retailing. The model was also applied to a real Italian case operating in the consumer electronics industry. Results highlighted that the search for synergies between online and traditional flows in both warehouse and transport activities is important for the economic sustainability of OC systems.","PeriodicalId":190544,"journal":{"name":"2017 IEEE International Conference on Service Operations and Logistics, and Informatics (SOLI)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114230024","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Salvadori","doi":"10.1109/SOLI.2017.8120964","DOIUrl":"https://doi.org/10.1109/SOLI.2017.8120964","url":null,"abstract":"Today cities are responsible for more than 75% of waste production, 80% of emissions, and 75% of energy utilization. With regard to Europe, road transportation produces about 20% of the total CO2 emissions, out of which 40% is generated by urban mobility. It is estimated that vehicles cruising for free parking spaces cause 30% of the daily traffic congestion in an urban downtown area. In this article we attempt to show, through a simulation and an assessment model, how ITS may impact on urban parking management considering both people and freight transportation, and quantified the economic and social benefits which can be obtained. Although some benefits have been already examined by previous authors (e.g. in terms of reduction of time spent in searching a free parking spot), there is still a general lack of quantitative models able to assess the impacts of ITS technologies for urban parking. In this regard, one distinctive contribution of this article is that it combines people and freight transportation modes in a single model. First, we developed a model in order to simulate the urban parking system before and after the adoption of the Smart Parking solution. The output of the simulation model consists in the percentage reduction of the time spent by drivers of cars and vans in searching a free parking spot. Then, this percentage has been used to assess the economic and social benefits of a Smart Parking application in the City of Milan (Italy), in which the “pay and display” parking spots are provided with sensors able to communicate if the space is free or not. The analysis considers two perspectives: on the one hand the parking operator company, which can increase its revenue due to the reduction of people that do not pay for parking. On the other hand, the city-users (i.e. citizens, tourists, off-site students, etc.), who can reduce the time spent for searching a free parking spot, thus reducing fuel consumption and CO2 emissions. The results obtained showed that these technologies would help each driver to save an average of 77.2 hours every year, 86.5 euros in fuel costs, and the entire city of Milan could reduce CO2 emissions by 44,470 tons per year (out of a total of 4,144,000 tons annually produced by road traffic in the area of Milan). In addition, these technologies help the parking operator company in improving the total revenue of around 9 million euros per year. If considering the required costs to implement the Smart Parking solution, the Discounted Payback Period for the parking operator is lower than 2 years.","PeriodicalId":190544,"journal":{"name":"2017 IEEE International Conference on Service Operations and Logistics, and Informatics (SOLI)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125371194","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
