the purpose of this article is to investigate a two-echelon supply chain inventory problem consisting of a single-vendor and a single-buyer with controllable lead time and investment for quality improvements. this paper presents an integrated vendor-buyer inventory model in order to minimize the sum of the ordering cost, holding cost, setup cost, investment for quality improvement and crashing ...

rapid expansions of new location-based services signify the need for finding accurate localization techniques for indoor environments. among different techniques, rss-based  schemes and in particular oneof its variants which is based on graph-based semi-supervised learning (g-ssl) are widely-used approaches the superiority of this scheme is that it has low setup/training cost and at the same ti...

This paper presents a feedback adjustment rule for discrete-part manufacturing processes that experience errors at the setup operation which are not directly observable due to part-topart variability and measurement error. In contrast to previous work on setup adjustment, the off-target cost function of the process is not symmetric around its target. Two asymmetric cost functions – constant and...

This paper presents a new mathematical model for a production system through a scheduling problem considering a material handling system as an intelligent transportation system by automated guided vehicles (AGVs). The traditional systems cannot respond to the changes and customer’s demands and for this reason, a flexible production system is used. Therefore, for this purpose, automated transpor...

Many techniques are available for estimating landslide surface displacements, whether from the ground, air- or spaceborne. In recent years, Unmanned Areal Vehicles have also been applied in domain of hazards, and able to provide high resolution precise datasets better understanding predicting movements mitigating their impacts. this study, we propose an approach monitoring detecting using a low...

Singlet microscopy is very attractive for the development of cost-effective and portable microscopes. In contrast to conventional microscope objectives, which consist multiple lenses, manufacturing process singlet lenses done without extensive assembling aligning. this manuscript, we report a novel virtual Zernike phase setup unstained pathological tumor tissue slides. setup, objective consists...

This paper models and solves the scheduling problem of cable manufacturing industries that minimizes total production cost, including processing, setup, storing costs. Two hybrid meta-heuristics, which combine simulated annealing variable neighbourhood search algorithms with tabu algorithm, are proposed. Applying some case-based theorems rules, a special initial solution optimal setup cost is o...

Imperfect quality items are unavoidable in an inventory system due to imperfect production process, natural disasters, damages, or many other reasons. The setup cost and production cycle time can be related in terms of process deterioration and learning and forgetting effects. Learning reduces production run length and setup cost, whereas deterioration and forgetting increases both. Keeping the...
