Two Sided GridPick System

Here is the newly developed two sided GridPick system. In this model, with the same size grid, there are two picking sides and pickers are moving back and forth to process orders on the pick face. With the order release policy, picker-1 picks odd numbered orders at the bottom, and picker-2 picks the item of...

3 Minute Thesis at Auburn University

I have recently attended 3 minute thesis event at Auburn University. Since it requires to summarize your dissertation in 3 minutes, it was quite an experience. It is also a good indication of how you describe and represent your work efficiently to an audience who is not familiar with your study area. Probably it will...

Petri Nets Modeling on GridPick

Petri nets is a tool for modeling of distributed, concurrent, and discrete event systems. In the Petri nets, tokens flow through the places via transition firings. Petri nets provide the capability of state space analysis for the structural properties of a model. Petri nets applications and modeled systems can be quite large and complex depending...

GridSequence

Sequencing problem appears in several operations of the intralogistics. In one common application, robotic palletizer workstations place the cartons on a pallet with the determined order according to a number of constraints such as space utilization, stability, fragility, etc. Therefore, robotic palletizers need to receive the orders in exact sequence. Our model sequences a random...

GridPick: A Dynamic Order Picking System

Order picking operations are still labor intensive and major part of the processing time consist of traveling to the items in the distribution center. Kevin Gue (my advisor) and I introduce a new order picking system for high pick density and low worker travel. Therefore, system provides high productivity in the order picking operations. GridPick is a semi-automated...

Physical System

Developed systems are based on a grid based architecture in which unit sized conveyors have controllers to perceive boxes and do the message passing with the neighbors. They are also able to convey in the four cardinal directions (North, South, East and West). Underlying technology for the puzzle based storage systems is called FlexConveyor. It...

Fun Fact

Our research is closely related to a board game called "Rush Hour". If you haven't played before, it is a really nice game. You can also try online versions of it. In this game, there are several interfering trucks and cars placed on the board with different orientations. The objective is to take the red...

GridFlow

GridFlow is an automated storage and retrieval system with high density and decentralized control. Requested items travel to the bottom row and leave the system. Interfering items move to the left and right with the "puzzle based movement rules" and allow the passage of the requested items. So, they form a temporary aisle there. For...

New Blog

Hi, I am just starting a new blog (thanks to wordpress). This site will mostly include updates about my research throughout my studies. I am working on puzzle based storage systems with decentralized control. It is about warehouse automation and intralogistics of distribution centers. There will be also some personal stuff and hobby things. Keep following...
