A multi-robot stage production is novel and challenging as different robots have to communicate and coordinate to produce a smooth performance. We made a multi-robot stage production possible using the NAO humanoid robots and the Lego Mindstorms NXT robots with a group of undergraduate women who had programming experience, but little experience with robots. The undergraduates from around the wo...

In this paper, we conduct a simulation study to evaluate the impact of using imperfect advance demand information (ADI) in a single stage production/inventory system. We mean by ADI the fact that the production system receives customer orders in advance of their due-dates. We consider four types of ADI: 1) Perfect ADI, 2) ADI with imperfect due-dates, 3) ADI with imperfect demand quantities and...

In just-in-time (JIT) production systems, there is both input stock in the form of parts and output stock in the form of product at each stage. These activities are controlled by production-ordering and withdrawal kanbans. This paper discusses a discrete-time optimal control problem in a multistage JIT-based production and distribution system with stochastic demand and capacity, developed to mi...

The objective of this study was to optimize continuous acetone-butanol-ethanol (ABE) fermentation using a two stage chemostat system integrated with liquid-liquid extraction of solvents produced in the first stage. This minimized end product inhibition by butanol and subsequently enhanced glucose utilization and solvent production in continuous cultures of Clostridium acetobutylicum B 5313. Dur...

The following note develops theorems which enable one to schedule operations on a single-stage production system so a s to minimize certain functions o r optimizers. It is shown that the maximum tardiness of job completion is minimized by ordering the jobs according to the date the job is due to be completed. The sum of t imes until eachjob is completed may be minimized under various conditions...

this paper introduces a novel approach to improve performance of speech recognition systems using a combination of features obtained from speech reconstructed phase space (rps) and frequency domain analysis. by choosing an appropriate value for the dimension, reconstructed phase space is assured to be topologically equivalent to the dynamics of the speech production system, and could therefore ...
