The four latent classes were given descriptive labels based on the pattern of service use that distinguished each class: Regular service use, Low service use, Declining service use and Selective service use. shows the probability of participation in each service event by service use group, and shows the distribution of service events by service use group.

Apollo web service adapter overview. To load data into Apollo the Apollo GUI calls the web service adapter GUI, which calls the web service adapter. The web service adapter invokes the web service client that communicates with the web service. The web service is deployed on an in house server that directly accesses the database. The database returns the information of interest to the web service and the web service returns it to the web service adapter. The web service returns the information as a GameXML formatted String and the GAME-XML adapter transforms the information into Apollo readable format. Subsequent the information can be loaded from the web service adapter into the Apollo main window. To write data back into the database or in a flat file the web service adapter receives the information as CurationSet from Apollo. This CurationSet will be send to the GAME-XML adapter to retrieve a GameXML formatted string, which can be transferred to the web service. The web service directs the information into the database or in a dedicated flat file.

In scenario A, four latency values are observed for the top service, one is missing for the bottom service. In scenario B, two latency values are missing for the top service, four latency values are observed for the bottom service.

Theoretical models of two dual-channel selling modes and logistics service modes. (a) Logistics service mode under the dual-channel structure of direct selling channel and reselling channel. In the dual-channel structure of direct selling channel + reselling channel, manufacturers sell products to e-commerce platforms at wholesale prices , and the e-commerce platforms sell products to customers at retail prices , while manufacturers sell products directly to customers at retail prices through direct channels (see a). On the one hand, the logistics service system of the e-commerce platform only provides logistics services for itself, and its logistics service level is expressed as . In the direct selling channel, the manufacturer buys logistics service from the third-party logistics service provider at unit price , and its logistics service level is expressed as , called the third-party logistics service model (see a(1)). On the other hand, the logistics service system of the e-commerce platform not only provides logistics services for itself but also provides logistics services for manufacturers. Manufacturers purchase logistics services from the e-commerce platform at unit price and use the e-commerce platform to represent their logistics service level , which is called the logistics service mode of the e-commerce platform (see a(2)). (b) Logistics service mode under the dual-channel structure of direct selling and agency channels. In the dual-channel structure of direct selling channel and agency channel, manufacturers sell products to customers through an e-commerce platform at retail price , and the e-commerce platform charges a proportional commission for each unit of product. Meanwhile, manufacturers sell products directly to customers at retail price through the direct selling channel (see b). First, the logistics service system of the e-commerce platform only provides logistics services for itself, and its logistics service level is expressed as . The manufacturer purchases logistics service from the third-party logistics service provider at unit price , and its logistics service level is expressed as , called the third-party logistics service model (see b(1)). Second, the logistics service system of the e-commerce platform not only provides logistics services for itself but also provides logistics services for manufacturers. Manufacturers purchase logistics services from the e-commerce platform at unit price and use the e-commerce platform to represent their logistics service level , which is called the logistics service model of an e-commerce platform (see b(2)).
