Transformation of optimization problems in revenue management, queueing system, and supply chain management

Wei, Yihua; Xu, Chen; Hu, Qiying - In: International Journal of Production Economics 146 (2013) 2, pp. 588-597

further apply our method to two optimal control problems in queueing systems and an inventory control problem in a supply …For revenue optimization problems in the literature on revenue management, supply chain management, and queueing … systems, some assumptions (such as concavity of revenue functions or increasing generalized failure rate) are often needed to …

Mathematical programming formulations for approximate simulation of multistage production systems

Alfieri, Arianna; Matta, Andrea - In: European Journal of Operational Research 219 (2012) 3, pp. 773-783

Mathematical programming representation has been recently used to describe the behavior of discrete event systems as well as their formal properties. This new way of representing discrete event systems paves the way to the creation of simpler mathematical programming models that reduce the...

When Promotions Meet Operations: Cross-Selling and Its Effect on Call Center Performance

Armony, Mor; Gurvich, Itai - In: Manufacturing & Service Operations Management 12 (2010) 3, pp. 470-488

We study cross-selling operations in call centers. The following questions are addressed: How many customer-service representatives are required (staffing), and when should cross-selling opportunities be exercised (control) in a way that will maximize the expected profit of the center while...

Optimisation of a generalised M(k)/M/k queueing system

Yang, Tao; Yue, Wuyi; Zhan, Jianfen; Hu, Qiying - In: International Journal of Revenue Management 3 (2009) 4, pp. 428-440

We study a generalised M(k)/M/k queueing system where the arrival rate depends on the number of servers. There are holding costs reflecting the waiting cost of customers and service costs relating to operation of the servers. The objective is to minimise the total system cost in a steady state....
