TL;DR: Results show that more spending and, under certain circumstances, using the fast shipping mode can provide sufficient motivation for the buyer to coordinate the order quantity and the service level decisions in the supply chain simultaneously.

TL;DR: Numerical results show that the hybrid system outperforms the traditional one in terms of infrastructure cost if the STDMA scheme is used and if the cost of a relay is 3 to 7% of the macro base station cost, depending on the desired service level.
Abstract: The infrastructure costs of a hybrid cellular-multihop and a traditional single-hop cellular system are compared in this paper with the help of a linear cost model. The cost is evaluated in a greenfield operator scenario most suited in a suburban type of environment, by defining a desired service level as achieved bit-rate per area unit [kbps/km/sup 2/]. The hybrid system consists of macro base stations and fixed wireless routers. The impact of the radio resource allocation scheme on the cost is exemplified with schemes: a cell-based TDMA scheme and a centralized STDMA scheme. Numerical results show that the hybrid system outperforms the traditional one in terms of infrastructure cost if the STDMA scheme is used and if the cost of a relay is 3 to 7% of the macro base station cost, depending on the desired service level.

TL;DR: This work considers a model mixed with retailing and e-tailing distribution channels where the service level and price decision are made, respectively, ex ante and ex post demand realizations, and characterize the effects of the demand uncertainty on the firm’s optimal retail service and expected profit.
Abstract: Together with regular retail channel, a firm can distribute products directly through Internet (referred to as an “e-tail” distribution channel). The competitive edge of the retail channel lies in more value-added services, some of which are unavailable through the e-tail channel. We consider a model mixed with retailing and e-tailing distribution channels where the service level and price decision are made, respectively, ex ante and ex post demand realizations. From the firm’s perspective of managing the two channels, we acquire the optimal decisions and characterize the effects of the demand uncertainty on the firm’s optimal retail service and expected profit. Applying stochastic comparison method, we show the firm’s retail service and profit both increase in the demand mean, and the firm profits from the increase of the convex order of the demand by decreasing his service level. Further, if the coefficient of the demand increases, we characterize that the firm benefits from it. Finally, several numerical studies are presented to gain insights.

TL;DR: In this paper, a call center for handling requests for medical transportation utilizes a system that assists a call centre agent by automatically determining, or prompting the agent to ask for, all information needed to assess the level of service required and the effects of any applicable contractual provisions.
Abstract: A call center for handling requests for medical transportation utilizes a system that assists a call center agent by automatically determining, or prompting the agent to ask for, all information needed to assess the level of service required and the effects of any applicable contractual provisions. The system captures information relating to the patient and the requested transportation, and applies service level rules representing the applicable regulatory requirements for medical transportation at the location of the patient to determine the required level of service based on the patient's condition and needs. The system further applies business rules representing the contractual provisions that are applicable to the requested transportation to determine responsibility for the cost of transportation, the authority of the requester to change the level of service or other aspects of the transportation, and the responsibility for the cost of transportation in the event that an aspect of the transportation has been changed.

TL;DR: This paper investigates the job-shop due-date assignment problem with a customer ‘service-level’ constraint, the percentage of time that promised delivery dates are honoured, and forms a rule to attain this service level, yet maintain as short a due- date lead time as possible.
Abstract: The job-shop due-date assignment problem arises when a manager needs to ‘promise’ a delivery date to a customer. Previous methods yield due-dates which are either optimistic (unlikely to be achieved) or conservative (the promise will be met, but too easily, because the date given was very pessimistic). This paper investigates the due-date assignment problem with a customer ‘service-level’ constraint, the percentage of time that promised delivery dates are honoured. We formulate a rule to attain this service level, yet maintain as short a due-date lead time as possible. Unlike previous attempts, this due-date rule considers not only the job content and instantaneous shop congestion information, but also implicitly incorporates information on how the jobs will be scheduled (or ‘loaded’) once they are in the shop. We simulate a single-machine shop for various measures of performance under several dispatching priorities, comparing our due-date rule with one reported to yield satisfactory performance. Our rule meets all requirements and is found to be superior for most measures of performance.
