In this paper, an algorithm is proposed to improve the Maximum Load Carrying Capacity (MLCC) of exible robot manipulators. The maximum allowable load which can be achieved by a exible manipulator along a given trajectory is limited by the joints' actuator capacity and the end e ector accuracy constraint. In an open-loop approach, the end e ector deviation from the prede ned path is signi cant a...

Optimal load of mobile robots, while carrying a load with predefined motion precision is an important consideration regarding their applications. In this paper a general formulation for finding maximum load carrying capacity of flexible joint mobile manipulators is presented. Meanwhile, overturning stability of the system and precision of the motion on the given end-effector trajectory are take...

Determining the production capacity of flexible manufacturing systems is a very important issue in the design of such systems. We propose an approach for determining the production capacity (i.e., the maximum production rate) of a flexible manufacturing system with several part types, dedicated pallets, and fixed production ratios among the different part types. We show that the problem reduces...

Cellulose nanofibrils (CNFs), which are generated from abundant, environmentally friendly natural plant resources, display numerous interesting properties such as outstanding mechanical strength, negligible light scattering, and low thermal expansion (Zimmermann et al., 2010). These nanofibers are usually created by mechanical fibrillation or chemical oxidation of pulp fibers. CNFs have previou...

Flexible and highly efficient energy storage units act as one of the key components in portable electronics. In this work, by planar-integrated assembly of hierarchical ZnCo₂O₄ nanowire arrays/carbon fibers electrodes, a new class of flexible all-solid-state planar-integrated fiber supercapacitors are designed and produced via a low-cost and facile method. The as-fabricated flexible devices exh...

T paper examines how the optimal investment in the capacity of flexible and nonflexible resources is affected by financial leverage and, conversely, how a firm’s resource flexibility affects its optimal capital structure. We consider a two-product firm that invests in the optimal capacity of product-flexible and productdedicated resources in the presence of demand uncertainty. Before investing ...

Avoiding deadlock is essential in the operation of highly automated manufacturing systems. Many of these systems support sufficient redundancy to permit flexible part routing. Although flexible routing improves the inherent operational flexibility of these systems, it also requires more highly sophisticated supervisory control techniques. The objective of this work is to characterize the deadlo...
