A mathematical framework for sequential passenger and baggage screening to enhance aviation security
To enhance security at both national and global levels, airport security screening systems must be designed with high efficiency and effectiveness, which are affected by both screening technologies and operational procedures for utilizing those ...
A replacement policy for a repairable system with its repairman having multiple vacations
This paper considers a replacement policy for a repairable system with a repairman, who can have multiple vacations. If the system fails and the repairman is on vacation, it will wait for repair until the repairman is available. Assuming that the system ...
Determining loading dock requirements in production-distribution facilities under uncertainty
Product handling activities play an important role in the operational aspects of a supply chain network. These activities apart from representing a major portion of the logistic costs, impede the product velocity and affect the lead time it takes to ...
Optimal multilevel redundancy allocation in series and series-parallel systems
To achieve truly optimal system reliability, the design of a complex system must address multilevel reliability configuration concerns at the earliest possible design stage, to ensure that appropriate degrees of reliability are allocated to every unit ...
An EPQ model with price discounted promotional demand in an imprecise planning horizon via Genetic Algorithm
An economic production quantity (EPQ) model for a newly launched product is developed in an imprecise planning horizon, i.e., lifetime of the product is fuzzy in nature. At the beginning of each cycle price discount is offered to boost the demand. ...
