An exact solution procedure for multi-item two-echelon spare parts inventory control problem with batch ordering in the central warehouse
Topan, Engin; Bayındır, Zeynep Pelin; Tan, Tarkan (Elsevier BV, 2010-09-01)
We consider a multi-item two-echelon inventory system in which the central warehouse operates under a (Q, R) policy, and the local warehouses implement basestock policy. An exact solution procedure is proposed to find the inventory control policy parameters that minimize the system-wide inventory holding and fixed ordering cost subject to an aggregate mean response time constraint at each facility.
An Exact Schedulability Test for Non-Preemptive Self-Suspending Real-Time Tasks
Yalcinkaya, Beyazit; Nasri, Mitra; Brandenburg, Bjoern B. (2019-01-01)
Exact schedulability analysis of limited-preemptive (or non-preemptive) real-time workloads with variable execution costs and release jitter is a notoriously difficult challenge due to the scheduling anomalies inherent in non-preemptive execution. Furthermore, the presence of self-suspending tasks is well-understood to add tremendous complications to an already difficult problem. By mapping the schedulability problem to the reachability problem in timed automata (TA), this paper provides the first exact sch...
An optimization model to coordinate scheduling and controling in projects: case with instantaneous control constraints
Hazir, Öncü; Schmidt, Klaus Verner; Eryilmaz, Utkan (National Technical University of Athens; 2014-01-01)
Today, many enterprises in different industries take part in various projects, and organizational performances depend more and more on project performances. In order to maximize performance, effective management of project functions is crucial. In this regard, we focus on scheduling and control functions and their relation. Characteristics of data sharing among them and possible integration strategies are theoretically investigated. A model base for a decision support framework that accounts for these inter...
An Algorithm for the forward step of adaptive regression slines via mapping approach
Kartal Koç, Elçin; Batmaz, İnci; İyigün, Cem; Department of Statistics (2012)
In high dimensional data modeling, Multivariate Adaptive Regression Splines (MARS) is a well-known nonparametric regression technique to approximate the nonlinear relationship between a response variable and the predictors with the help of splines. MARS uses piecewise linear basis functions which are separated from each other with breaking points (knots) for function estimation. The model estimating function is generated in two stepwise procedures: forward selection and backward elimination. In the first st...
An Objective-Based Design Approach of Retaining Walls Using Cuckoo Search Algorithm
Tutuş, Eren Burak; Ghalandari, Taher; Pekcan, Onur (null, Springer, 2020-01-01)
In the past two decades, there has been ongoing trend to design retaining walls in an optimal way rather than the conventional trial and-error approach. In this study, reinforced concrete cantilever retaining wall is optimized using the Cuckoo Search (CS) algorithm, a metaheuristic swarm-based method that imitates the reproductive behavior of cuckoo birds. To obtain the optimal solution, design requirements are expressed as constraints to overcome violated solutions. Together with a mathematical definition ...
