This study considers a flowshop type production system consisting of m machines. A material handling robot transports the parts between the machines and loads and unloads the machines. We consider the sequencing of the robot moves and determining the speeds of these moves simultaneously. These decisions affect both the robot's energy consumption and the production speed of the system. In this study, these two objectives are considered simultaneously. We propose a second order cone programming formulation to find Pareto efficient solutions. We also develop a heuristic algorithm that finds a set of approximate Pareto efficient solutions. The conic formulation can find robot schedules for small cells with less number of machines in reasonable computation times. Our heuristic algorithm can generate a large set of approximate Pareto efficient solutions in a very short computational time. Proposed solution approaches help the decision-maker to achieve the best trade-off between the throughput of a cell and the energy efficiency of a material handling robot.

Scheduling in two-machine robotic cells with a self-buffered robot Gündoğdu, Emine; GÜLTEKİN, HAKAN (2016-02-01) This study considers a production cell consisting of two machines and a material handling robot. The robot has a buffer space that moves with it. Identical parts are to be produced repetitively in this flowshop environment. The problem is to determine the cyclic schedule of the robot moves that maximizes the throughput rate. After developing the necessary framework to analyze such cells, we separately consider the single-, double-, and infinite-capacity buffer cases. For single- and double-capacity cases, c...
Spray rolling of rapidly solidified Al-FeV-Si alloy Özyurda, Halit Akın; Kalkanlı, Ali; Department of Metallurgical and Materials Engineering (2006) In this study an experimental spray-rolling set-up is designed in order to produce rapidly solidified Al-Fe-V-Si flat product. Al-Fe-V-Si alloys produced by rapid solidification powder metallurgy (RSP/M) methods are mostly used in high temperature applications in aerospace and automotive industries. The RSP/M technique used is spray deposition, which is desirable because of the high cooling rates achieved, as a result fine silicide dispersoids and intermetallics are observed in the microstructure which are ...
Development of a 3 axes PC numerical control system for industrial applications Başar, Feza; Hızal, Mirzahan; Department of Electrical and Electronics Engineering (2003) In this study, a three-axes PC numerical control system for industrial applications has been developed. With this system, fast and cheap prototyping of designed objects can be realized. The system consists of software and a hardware which includes an XYZ positioning table and three step motors controlling this table. A proper drive circuit for the stepper motors is utilized. The software digitizes two dimensional drawings of three dimensional objects and generates the control signals for the XYZ positioning...
Collaborative building control: a conceptual mixed-initiative framework Topak, Fatih; Pekeriçli, Mehmet Koray (Taylor & Francis, 2021-6-22) In the last two decades, automation systems have shown advanced developments and are widely adopted for various purposes in many fields. However, automation in buildings has not gained popularity and has a low acceptance level amongst the occupants. Decreased perceived control, ever-changing dynamic human needs, and standardized, one-size-fits-all approach in current automation systems lead to disharmony in human-machine coexistence. Although well-established continuous interaction between building control ...
A capacity allocation problem in flexible manufacturing systems Bilgin, Selin; Azizoğlu, Meral; Department of Industrial Engineering (2004) In this study, we consider a capacity allocation problem in flexible manufacturing systems. We assume time and tool magazine capacities on the Numerical Controlled (NC) machines and limited number of available tools. Our problem is to allocate the available capacity of the NC machines to the required demand of the operations, so as to maximize the total weight of operation assignments. We formulate the problem as a Mixed Integer Linear Program and show that it is NP-hard in the strong sense. We solve the mo...
