Key initiatives to improve the machining characteristics of Inconel-718 alloy: Experimental analysis and optimization
(Elsevier, 2022-11-03)Inconel 718 is a heat-resistant Ni-based superalloy widely used, particularly, in aircraft and aero-engineering applications. It has poor machinability due to its unique thermal and mechanical properties. For this reason, ... -
Impact of commitment, information sharing, and information usage on supplier performance: a Bayesian belief network approach
(Springer Nature, 2019-12-19)Due to the proliferation of information systems and technology, supply chains have the capability of acquiring an enormous amount of supplier data in their databases. However, much of the useful supplier-specific insights ... -
Effectiveness of capacity rationing heuristics in make to order environment
(Inderscience Publishers, 2015)This paper investigates the effectiveness of a dynamic capacity-rationing heuristic for order acceptance and rejection in a capacitated make-to-order manufacturing environment. The heuristics developed for managing capacity ... -
Visit length in pediatric primary care: lessons from a pilot study
(Greenbranch Publishing, 2013-05)As business drivers create pressure to see more patients in a given period, there is no reliable guidance regarding the optimal allocation of resources in ambulatory visits. Many pediatric primary clinics set appointment ... -
A toll pricing framework for traffic assignment problems with elastic demand
(Springer, 2001-12)This paper extends the notion of toll pricing and the toll pricing framework previously developed for fixed demand traffic assignment [4, 13] to the problem with elastic demand. The system problem maximizes net benefit to ... -
Hospital patient-care and outside-the-hospital energy profiles for hemodialysis services: report of two cases
(John Wiley & Sons Inc., 2015-06)Studies investigated the patient-care (in-hospital) and outside-the-hospital energy consumptions for delivering the hemodialysis (HD) service. A life cycle inventory methodology was used for this patient-based analysis for ... -
Integrated maintenance and production planning with energy consumption and minimal repair
(Springer, 2014-10)In this study, we analyze an integrated production-preventive maintenance planning problem where product processing times are affected by machine degradation. Preventive maintenance and repair can return the degraded ... -
A sustainability approach for selecting maintenance strategy
(Taylor & Francis, 2013-03)Appropriate maintenance can prolong the life of an asset and prevent costly breakdowns that may result in lost production, failed shipping schedules and a decline in customer satisfaction. The goal of this study was to ... -
A fuzzy multicriteria generation expansion planning model
(Inderscience Publishers, 2011)In this paper, we present a fuzzy multi-objective model for power generation expansion planning problem with uncertainty in objective functions and demand balance constraints. The purpose of the fuzzy generation expansion ... -
Single-machine sustainable production planning to minimize total energy consumption and total completion time using a multiple objective genetic algorithm
(IEEE-INST Electrical Electronics Engineers Inc, 2012-11)Energy is an expensive resource that is becoming more scarce with increasing population and demand. In this paper, a mathematical model to minimize energy consumption and reduce total completion time of a single machine ... -
Single-machine sustainable production planning to minimize total energy consumption and total completion time using a multiple objective genetic algorithm
(IEEE Technology Management Council, 2011-11-18)Energy is an expensive resource that is becoming more scarce with increasing population and demand. In this paper, a mathematical model to minimize energy consumption and reduce total completion time of a single machine ... -
An ant colony optimization algorithm for load balancing in parallel machines with sequence dependent setup times
(Elsevier, 2010)This study introduces the problem of minimizing average relative percentage of imbalance (ARPI) with sequence-dependent setup times in a parallel-machine environment. A mathematical model that minimizes ARPI is proposed. ... -
A new dominance rule for the total weighted tardiness problem
(Taylor & Francis, 1999)We present a new dominance rule for the single machine total weighted tardiness problem with job dependent penalties. The proposed dominance rule provides a su cient condition for local optimality. We show that if any ... -
A new lower bounding scheme for the total weighted tardiness problem
(Elsevier, 1998)We propose a new dominance rule that provides a sufficient condition for local optimality for the 1∥∑wiTi problem. We prove that if any sequence violates the proposed dominance rule, then switching the violating jobs ... -
A neuro-genetic approach to design and planning of a manufacturing cell
(Springer Verlag, 2005)In this paper, we propose a neuro-genetic decision support system coupled with simulation to design a job shop manufacturing system by achieving predetermined values of targeted performance measures such as flow time, ... -
A first best toll pricing framework for variable demand traffic assignment problems
(Elsevier, 2005)In this paper, we present a toll pricing framework for a general variable demand traffic assignment problem with side constraints, where the demand between an origin destination pair is a function of the least total travel ... -
Workload balancing in printed circuit board assembly shops
(2005)In assembling printed circuit boards (PCB), the use of numerically or computer controlled electronic component placement machines has become quite popular in the last decades. However, serious operations research problems ... -
Dispatching rules for allocation of component types to machines in the automated assembly of printed circuit boards
(Springer Verlag, 2006)In this paper, we propose a model and algorithms to solve a load balancing problem on a printed circuit board assembly line. On this line of two identical machines, the problem of allocation of component types to ... -
Machine number, priority rule, and due date determination in flexible manufacturing systems using artificial neural networks
(Elsevier, 2006-05-11)When there is a production system with excess capacity, i.e. more capacity than the demand for the foreseeable future, upper management might consider utilizing only a portion of the available capacity by decreasing the ...
