Analysis of the (s, S) policy for perishables with a random shelf life
(Taylor & Francis, 2008)
A continuous review perishable inventory system operating under the (s,S) policy is considered. Assuming a random shelf life with a general distribution, renewal arrivals and a negligible replenishment lead time, exact ...
Age-based vs. stock level control policies for a perishable inventory system
In this study, we investigate the impact of modified lotsize-reorder control policy for perishables which bases replenishment decisions on both the inventory level and the remaining lifetimes of items in stock. We derive ...
Robustness and stability measures for scheduling: single-machine environment
(Taylor & Francis, 2008)
This paper addresses the issue of finding robust and stable schedules with respect to random disruptions. Specifically, two surrogate measures for robustness and stability are developed. The proposed surrogate measures, ...
Experimental investigation of iterative simulation-based scheduling in a dynamic and stochastic job shop
A vital component of modern manufacturing systems is the scheduling and control system, which determines companies' overall performance in their respective supply chains. This paper studies iterative simulation-based ...
Bundle pricing of inventories with stochastic demand
We consider a retailer selling a fixed inventory of two perishable products over a finite horizon. Assuming Poisson arrivals and a bivariate reservation price distribution, we determine the optimal product and bundle prices ...
The role of repair strategy in warranty cost minimization: an investigation via quasi-renewal processes
Most companies seek efficient rectification strategies to keep their warranty related costs under control. This study develops and investigates different repair strategies for one- and two-dimensional warranties with the ...
Input data analysis using neural networks
(Sage Publications, 2000)
Simulation deals with real-life phenomena by constructing representative models of a system being questioned. Input data provide a driving force for such models. The requirement for identifying the underlying distributions ...
Analysis of serial production lines: Characterisation study and a new heuristic procedure for optimal buffer allocation
(Taylor & Francis, 2006)
Buffer allocation in serial production lines is one of the important design issues, and hence it has been studied extensively in the literature. In this paper, we analyse the problem to characterise the optimal buffer ...
Assembly line balancing using genetic algorithms
(Kluwer Academic Publishers, 2000)
Assembly Line Balancing (ALB) is one of the important problems of production/operations management area. As small improvements in the performance of the system can lead to significant monetary consequences, it is of utmost ...
