As a result, so-called Communication Service Providers play an important role in today’s business life. Their orders have to be carried out promptly and dependably, let them be requests for new installations, modifications, or maintenance tasks. These orders have to be performed at different locations and they often have deadlines or strict starting times. Violating such a timing requirement usually implies penalties. In this paper, scheduling problems arising at a Hungarian service provider are examined. At this company, orders are decomposed into smaller tasks, which can be performed by specially trained personnel. Transportation of these specialists contributes a lot to the costs and to the complexity of their scheduling, as well. The goal is to minimize the overall cost of satisfying all orders within the given time horizon with the available assets of the company. The proposed approach relies on the S-graph framework, which has been applied to various production scheduling problems in the literature. In addition to an unambiguous and sound S-graph model of the examined problem, slight modifications of the scheduling algorithms for cost minimization, and new bounding methods have been developed. Several of such bounds have been provided and tested for performance and scalability over a large number of generated examples. The sensitivity of the approach for certain problem features has also been examined.}, year = {2020}, eissn = {1936-6590}, pages = {913-948}, orcid-numbers = {Holczinger, Tibor/0000-0003-4427-9253; Ősz, Olivér/0000-0001-5306-0451; Hegyháti, Máté/0000-0003-3689-9866} } @article{MTMT:25379681, title = {Systematic approach for designing and activities' scheduling of supply chain network}, url = {https://m2.mtmt.hu/api/publication/25379681}, author = {Adonyi, R and Kirilova, EG and Vaklieva-Bancheva, NG}, journal-iso = {BULG CHEM COMMUN}, journal = {BULGARIAN CHEMICAL COMMUNICATIONS}, volume = {45}, unique-id = {25379681}, issn = {0324-1130}, year = {2013}, eissn = {0861-9808}, pages = {288-295} } @CONFERENCE{MTMT:23534274, title = {Analysis on Production Processe Optimization of Small-Mddle Float Glass Manufacturer.
