TL;DR: This paper considers how to compute the start-service time and arrival time distributions for each customer to create a feasibility check that can be “plugged” into any algorithm for the SVRPTW and thus be used to solve large problems fairly quickly.

TL;DR: Evidence is provided that a coordinated production–ordering contingency policy in the supply chain within and after the disruption period has been developed and tested to reduce the negative impacts of the ‘postponed redundancy’.
Abstract: Performance impacts of ordering and production control policies in the presence of capacity disruptions are studied on the real-life example of a retail supply chain with product perishability considerations. Constraints on product perishability typically result in reductions in safety stock and increases in transportation frequency. Consideration of the production capacity disruption risks may lead to safety stock increases. This trade-off is approached with the help of a simulation model that is used to compare supply chain performance impacts with regard to coordinated and non-coordinated ordering and production control policies. Real data of a fast moving consumer goods company is used to perform simulations and to derive novel managerial insights and practical recommendations on inventory, on-time delivery and service level control. In particular, for the first time, the effect of ‘postponed redundancy’ has been observed. Moreover, a coordinated production–ordering contingency policy in the supply chain within and after the disruption period has been developed and tested to reduce the negative impacts of the ‘postponed redundancy’. The lessons learned from experiments provide evidence that a coordinated policy is advantageous for inventory dynamics stabilization, improvement in on-time delivery, and variation reduction in customer service level.

Journal ArticleDOI
TL;DR: A Lagrangian multiplier technique based algorithmic approach is proposed, which evaluates a very limited number of combinations of lead time of the buyers to find simultaneously the optimal lead time, order quantity and safety factor of the buyer and the number of shipments between the vendor and the buyers in a production cycle.

TL;DR: In this paper, a method of initiating a wireless communication session with a communication network is provided, where a cost estimate for the communication session is determined based on a quality of service level and a quantity of information to be communicated.
Abstract: A method of initiating a wireless communication session with a communication network is provided. A cost estimate for the communication session is determined based on a quality of service level and a quantity of information to be communicated. The communication session is initiated when the cost estimate is accepted. In one embodiment, the user may select a second quality of service level for the communication session when the first cost estimate is not accepted and is provided a second cost estimate for the second quality of service level. In yet another embodiment, a communication session is initiated when there is sufficient balance available to the wireless communication device or a user's smart card for a communication session at a quality of service level selected by the user. In one embodiment, the method may be performed in accordance with a packet radio service network providing packet data services.

TL;DR: In this paper, the effects of an order allocation procedure in a supply chain are studied, where the authors developed a solution algorithm and tested it to examine its effectiveness in terms of the service level and the company's total purchasing cost.
