Optimal and Self Selection of Service Type in a Queueing System where Long Service Postpones the Need for the Next Service
Refael Hassin, Jiesen Wang
We study a make-to-order system with a finite set of customers. Production is stochastic with a nonlinear dependence between the ordered quantity and the production rate. Customers…
How Advance Sales can Reduce Profits: When to Buy, When to Sell, and What Price to Charge
Amihai Glazer, Refael Hassin, Irit Nowik
A consumer who wants to consume a good in a particular period may nevertheless attempt to buy it earlier if he is concerned that in delaying he would find the good already sold. Th…
A strategic model of job arrivals to a single machine with earliness and tardiness penalties
Amihai Glazer, Refael Hassin, Liron Ravner
We consider a game of decentralized timing of jobs to a single server (machine) with a penalty for deviation from a due date, and no delay costs. The jobs' sizes are homogeneous an…
On the price of anarchy in a single server queue with heterogenous service valuations induced by travel costs
Refael Hassin, Irit Nowik, Yair Y. Shaki
This work presents a variation of Naor's strategic observable model (1969), by adding a component of customer heterogeneity induced by the location of customers in relation to the…
Delay-minimizing capacity allocation in an infinite server queueing system
Refael Hassin, Liron Ravner
We consider a service system with an infinite number of exponential servers sharing a finite service capacity. The servers are ordered according to their speed, and arriving custom…
Minimum diameter and cycle-diameter orientations on planar graphs
Nili Guttmann-Beck, Refael Hassin
Let G be an edge weighted undirected graph. For every pair of nodes consider the shortest cycle containing these nodes in G. The cycle diameter of G is the maximum length of a cycl…
