TL;DR: In this article, a system and method for detecting or reporting service level or service outages on a network includes a meta service generator that operates on network inventory to generate service definitions.
Abstract: A system and method for detecting or reporting service level or service outages on a network includes a meta service generator that operates on a network inventory to generate service definitions. The system is a server-based model, and each service definition includes usergroup and points of presence, thus instantiating multiple services in a manner that allows the definition to focus on relevant element events amid massive network event data, and detect service outages quickly and dependably. The outages, transaction spec outages and events so determined may be aggregated to provide overall measures that are compared with thresholds, performance criteria and other service metrics specified in a user Service Level Agreement (SLA) for billing, credit, evaluation or other purposes. Batch processing embodiments may operate with outage logs, and employ a concurrence algebra to correct outage intervals for planned and forced outages, providing a truer measure of performance that allows the system to generate multiple different reports reflecting different compensable or inconsequential outage states.

TL;DR: A hybrid multi-criteria method which is fuzzy analytic hierarchy process (FAHP) and fuzzy vlsekriterijumska optimizacija i kompromisno resenje (FVIKOR) is exploited to offer decision-makers an integrated and consistent model for evaluating and selecting the most efficient 3PLs.
Abstract: With the effects of the COVID-19 pandemic, the e-commerce trend is driving faster, significantly impacting supply chains around the world. Thus, the importance of logistics and supply chain functions has been amplified in almost every business that ships physical goods. In Vietnam, the logistics service sector has seen rapid expansion. Since more and more businesses are seeking third-party logistics (3PL) providers to outsource the logistics functions, this article aims to offer decision-makers an integrated and consistent model for evaluating and selecting the most efficient 3PLs. To this end, the authors exploit a hybrid multi-criteria method which is fuzzy analytic hierarchy process (FAHP) and fuzzy vlsekriterijumska optimizacija i kompromisno resenje (FVIKOR) while examining the most influential and conflicting criteria regarding economic, service level, environmental, social, and risk aspects. Fuzzy information in the natural decision-making process is considered, linguistic variables are used to mitigate the uncertain levels in the criteria weights. First, FAHP (the weighting method) is adopted to evaluate and calculate each criterion’s relative significant fuzzy weight. FVIKOR (the compromised ranking method) is then used to rank the alternatives. The combination of FAHP and FVIKOR methods provides more accurate ranking results. As a result, reliability and delivery time, voice of customer, logistics cost, network management, and quality of service are the most impactful factors to the logistics outsourcing problem. Eventually, the optimized 3PLs were determined that fully meet the criteria of sustainable development. The developed integrated model offers the complete and robust 3PLs evaluation and selection process and can also be a powerful decision support tool for other industries.

TL;DR: There is a limit to which reductions in coordination costs for on-line source substitution and associated inventory availability decisions can provide benefit, and this limit is influenced by both the proportion of the market managed through on-lines sales and the service level constraints in place for both on-LINE and in-store channels.

TL;DR: The results of this study show that both perceptions and expectations of the passengers’ are important to estimate the service quality of the city bus service.
Abstract: This study aims to find out the service quality of the city bus service based on users’ perceptions and expectations of the service. The results of this study show that both perceptions and expectations of the passengers’ are important to estimate the service quality. To collect the passengers’ perceptions and expectations data, a questionnaire survey has been conducted and the respondents are asked to rate some qualitative attributes of the city bus service as per their perceptions and their minimum expectations from the service. Data has been analyzed by a combination of statistical tools comprising of factor analysis, linear regression analysis, and structural equation modeling to find out the latent factors which affect users’ perception and expectation. From these analysis four latent factors namely safety, comfort, accessibility, and timely performance have been extracted along with their perceived and expected values. Using the percentage differences of the perceived and expected values, a level of service (LOS) scale has been established to find out the service level of the city bus service. The range of this LOS scale varies from LOS 1 to LOS 5 depicting best to worst service quality. It is found that, safety, comfort, and timely performance fall under LOS 3 group while accessibility falls under LOS 2 group. Based on the results of the study, some recommendations have been made to improve the service quality of the bus service.
